Question: The potential impact of the permafrost's carbon release in the Arctic may be significantly stronger than previously estimated, with substantial releases of methane—a greenhouse gas less enduring yet considerably more powerful—that could trigger accelerated episodes of climate change.

 Amplified Methane Release: A Looming Threat Amidst Climate Change
The escalating concern regarding methane emissions from the Arctic underscores how much more impactful they can prove compared to initial estimations—potentially igniting rapid surges in global temperatures. This phenomenon occurs when vast amounts of methane—a highly potent yet short-lived greenhouse gas—are released into the atmosphere from thawed permafrost areas across the Arctic landscape. Historically, the emission of methane was part of a balanced ecological cycle; however, anthropogenic climate change has accelerated this process exponentially.

As global temperatures rise, so do the risks associated with increased methane liberation. Not only does this stem from the destabilization of pre-existing reservoirs within frozen grounds, but also through enhanced microbial generation in decomposing organic matter. These circumstances create a perilous feedback loop where additional atmospheric heat leads to greater methane output, thereby exacerbating planetary warming.

Significant volumes of methane remain trapped below ground level within various forms – underground gas reserves, submerged ice structures known as clathrates, and expansive stretches of perennially frozen earth (permafrost). When subjected to warmer conditions, these storage mechanisms weaken, potentially unleashing substantial quantities onto unsuspecting surroundings. Additional contributors comprise underwater defrosted zones, freshwater conveyance systems transporting dissolved gases downstream, retreating glacial complexes exposing fresh surfaces prone to bacterial action, alongside deteriorated subaqueous sedimentary layers rich in hydrocarbons.

Current measurements reveal that concentrations near northern latitudes exceed those observed closer to Antarctica by approximately ten percent. Throughout colder periods characterized by extensive glaciation, differences diminish almost entirely suggesting terrestrial biospheres play pivotal roles behind observed disparities rather than solely oceanic influences being overlooked hitherto. Moisture content coupled with thermal gradients govern dynamics governing gaseous exchange occurring amongst alpine substrata contributing substantially towards overall atmospheric burdens emanating therefrom.

A dead-end job is a pejorative term used to describe a job in which there is little or no chance of career development and advancement into a higher paid position .   Such work is usually regarded as unskilled and the phrase usually applies to those working as shelf stackers , cleaners , call center agents , clerks , or in other menial jobs where the pay is low , and the hours are long . Furthermore , positions not regarded as menial may nonetheless qualify as dead-end jobs and forms of underemployment . A specialized employee working in a small firm in an underdeveloped local market , for example , might have few opportunities for advancement within the company while simultaneously facing a dearth of opportunities outside it . Most dead-end jobs offer little to no transferable skills and may `` trap '' workers .   Dead-end jobs are not limited to menial labor , retail or fast food roles . Professional positions in call centers , loss-mitigation underwriting , administrative and clerical work may offer almost no advancement potential . Another common indicator of a dead-end job is the risk of it being made obsolete by automation .

Deflagration ( Lat : de + flagrare , `` to burn down '' ) is subsonic combustion propagating through heat transfer ; hot burning material heats the next layer of cold material and ignites it . Most `` fires '' found in daily life , from flames to explosions , are deflagrations . Deflagration is different from detonation , which propagates supersonically through shock waves . This means that when a substance deflagrates , it burns extremely quickly instead of detonating . Black powder is an example of a substance that deflagrates ; when it is ignited , black powder burns extremely quickly ( so fast in fact that the burn is sometimes mistaken for a detonation ) .

`` Regeneration '' is the forty-ninth episode of the American science fiction television series Star Trek : Enterprise , the twenty-third episode of the second season . It first aired on May 7 , 2003 on the UPN network in the United States . The episode was written by Mike Sussman and Phyllis Strong , and was directed by David Livingston . It was a follow-up to the feature film Star Trek : First Contact , and a prelude to the Battle of Wolf 359 ( as seen in `` The Best of Both Worlds '' . )   Set in the 22nd century , the series follows the adventures of the first Starfleet starship Enterprise , registration NX-01 . In this episode , several cybernetically enhanced aliens are accidentally reanimated by a research team in the Arctic . The aliens assimilate the researchers and their ship before escaping into space . The Enterprise pursues the ship and is attacked , forcing Archer to destroy the vessel . Afterwards they discover that the aliens sent a message into the Delta Quadrant containing the coordinates of Earth , a message that will not arrive until the 24th century .   The episode utilised props and costumes from previous Star Trek series in order to represent the Borg and is where they make their last canon appearance . The guest cast including Bonita Friedericy , the wife of main cast member John Billingsley . The ratings received by the episode were similar to those received during the previous week , and the number of viewers were one of the highest for the year . The critical response to `` Regeneration '' was mixed , with concerns directed at potential continuity problems , and that the appearance of the Borg was a little obvious . A follow-up episode to `` Regeneration '' featuring the return of Alice Krige as the Borg Queen was pitched for the fifth season of Star Trek : Enterprise but the show was cancelled before the fifth season could be released and thus the episode never aired .

Lauge Koch ( 5 July 1892 -- 5 June 1964 ) was a Danish geologist and Arctic explorer .   He was the renowned leader of 24 Danish government expeditions to Greenland , and the central character in the Lauge Koch Controversy , an international and intra-national conflict . Beginning in December 1935 a bitter conflict arose between Koch and eleven of the most prominent Danish geologists of the day , including O. B. Bøggild , director of The Mineralogical Museum and professor at the Geological Institute of Copenhagen University , and , head of the Geological Survey of Denmark .   Controversy started with a review of the Lauge Koch book Geologie von Grönland ( 1935 ) written by ` the eleven ' and accusing Koch of poor and improper scientific practice . Relating to the years 1921 -- 23 in which Lauge Koch conducted the Bicentenary Jubilee Expedition to North Greenland in the year of the bicentennial jubilee of Hans Egede 's landing in Greenland , Koch made a sledge journey along the north coast of Greenland , round Peary Land and back across the Inland Ice . On this journey Koch discovered a depression which in his opinion was the one that Robert Peary in 1892 had mistaken for a channel . Koch 's observations of the interior of Independence Fjord led to considerable cartographic changes compared with the Peter Freuchen map of 1912 .   In 1938 , Lauge Koch found in the mountains west of Jameson Land , near Scoresby Sound , the skeleton of a huge extinct mammal similar to the head of a gigantic animal with huge teeth found by Professor Selim Hassan in 1935 near the pyramid of Chephren . The skeleton found by Koch was displayed at the museum in Copenhagen .   Amongst his other contributions to the sciences , in the mid-1930s Koch established a network of field stations and traveling huts in Central East Greenland . This establishment of a permanent infrastructure in the field caused a change in the whole culture and organization of Danish Arctic exploration .   The mineral kochite which is found in Mt Hvide Ryg , Werner Bjerge , and the former Greenland county of Tunu was named for Koch in honor of his explorations in the same areas .   His last expedition would be the 1956-58 Expedition to East Greenland in which he used helicopters . But the Danish government cut funding in mid-expedition and Koch 's career as expedition leader was terminated .

is a Japanese supernatural manga series by Karakara-Kemuri . It was serialized by Mag Garden on Monthly Comic Avarus magazine . It has been adapted into an anime television series .

An anime theatrical film trilogy adaptation by Wit Studio was announced , with each part running for 60 minutes and the first part scheduled for release in 2017 . A live-action film adaptation  is scheduled for release in February 2018 .

Decapitation is the complete separation of the head from the body . Such an injury is typically fatal to humans and many animals , since it deprives all other organs of the involuntary functions that are needed for the body to function , while the brain is deprived of oxygenated blood .   The term beheading refers to the act of deliberately decapitating a person , either as a means of murder or execution ; it may be accomplished , for example , with an axe , sword , knife , or by other more sophisticated means such as a guillotine . An executioner who carries out executions by beheading is called a headsman . Accidental decapitation can be the result of an explosion , car or industrial accident , improperly administered execution by hanging or other violent injury . Suicide by decapitation is rare but not unknown . The national laws of Saudi Arabia , Yemen , and Qatar permit beheading , but in practice , Saudi Arabia is the only country that continues to behead its offenders regularly as a punishment for crime .   Less commonly , decapitation can also refer to the removal of the head from a body that is already dead . This might be done to take the head as a trophy , for public display , to make the deceased more difficult to identify , for cryonics , or for other , more esoteric reasons .

Dieting is the practice of eating food in a regulated and supervised fashion to decrease , maintain , or increase body weight . In other words , it is conscious control or restriction of the diet . A restricted diet is often used by those who are overweight or obese , sometimes in combination with physical exercise , to reduce body weight . Some people follow a diet to gain weight ( usually in the form of muscle ) . Diets can also be used to maintain a stable body weight and improve health . In particular , diets can be designed to prevent or treat diabetes .   Diets to promote weight loss can be categorized as : low-fat , low-carbohydrate , low-calorie , very low calorie and more recently flexible dieting . A meta-analysis of six randomized controlled trials found no difference between low-calorie , low-carbohydrate , and low-fat diets , with a 2 -- 4 kilogram weight loss over 12 -- 18 months in all studies . At two years , all calorie-reduced diet types cause equal weight loss irrespective of the macronutrients emphasized . In general , the most effective diet is any which reduces calorie consumption .   A study published in American Psychologist found that short-term dieting involving `` severe restriction of calorie intake '' does not lead to `` sustained improvements in weight and health for the majority of individuals '' . Other studies have found that the average individual maintains some weight loss after dieting . Weight loss by dieting , while of benefit to those classified as unhealthy , may slightly increase the mortality rate for individuals who are otherwise healthy .   The first popular diet was `` Banting '' , named after William Banting . In his 1863 pamphlet , Letter on Corpulence , Addressed to the Public , he outlined the details of a particular low-carbohydrate , low-calorie diet that had led to his own dramatic weight loss .

Komatiite ( -LSB- pronkoʊˈmɑːti.aɪt -RSB- ) is a type of ultramafic mantle-derived volcanic rock . Komatiites have low silicon , potassium and aluminium , and high to extremely high magnesium content . Komatiite was named for its type locality along the Komati River in South Africa .   True komatiites are very rare and essentially restricted to rocks of Archean age , with few Proterozoic or Phanerozoic komatiites known ( although high-magnesian lamprophyres are known from the Mesozoic ) . This restriction in age is thought to be due to cooling of the mantle , which may have been up to 500 ° C hotter during the early to middle Archaean ( 3.8 to 2.8 billion years ago ) . The early Earth had much higher heat production , due to the residual heat from planetary accretion , as well as the greater abundance of radioactive elements .   Geographically , komatiites are restricted in distribution to the Archaean shield areas . Komatiites occur with other ultramafic and high-magnesian mafic volcanic rocks in Archaean greenstone belts . The youngest komatiites are from the island of Gorgona on the Caribbean oceanic plateau off the Pacific coast of Colombia .

A knockout ( abbreviated to KO or K.O. ) is a fight-ending , winning criterion in several full-contact combat sports , such as boxing , kickboxing , muay thai , mixed martial arts , karate , some forms of taekwondo and other sports involving striking . A full knockout is considered any legal strike or combination thereof that renders an opponent unable to continue fighting .   The term is often associated with a sudden traumatic loss of consciousness caused by a physical blow . Single powerful blows to the head ( particularly the jawline and temple ) can produce a cerebral concussion or a carotid sinus reflex with syncope and cause a sudden , dramatic KO . Body blows , particularly the liver punch , can cause progressive , debilitating pain that can also result in a KO .   In boxing and kickboxing , a knockout is usually awarded when one participant falls to the canvas and is unable to rise to their feet within a specified period of time , typically because of exhaustion , pain , disorientation , or unconsciousness . For example , if a boxer is knocked down and is unable to continue the fight within a ten-second count , they are counted as having been knocked out and their opponent is awarded the KO victory .   In mixed martial arts ( MMA ) competitions , no time count is given after a knockdown , as the sport allows submission grappling as well as ground and pound . If a fighter loses consciousness ( `` goes limp '' ) as a result of legal strikes it is declared a KO . Even if the fighter loses consciousness for a brief moment and wakes up again to continue to fight , the fight is stopped and declared a KO . As many MMA fights can take place on the mat rather than standing , it is possible to score a KO via ground and pound , a common victory for grapplers .

In seismology , the depth of focus or focal depth refers to the depth at which an earthquake occurs . Earthquakes occurring at a depth of less than 70 km are classified as shallow-focus earthquakes , while those with a focal depth between 70 km and 300 km are commonly termed mid-focus or intermediate-depth earthquakes . In subduction zones , where older and colder oceanic crust descends beneath another tectonic plate , deep-focus earthquakes may occur at much greater depths in the mantle , ranging from 300 km up to 700 km .   The cause of deep-focus earthquakes is still not entirely understood since subducted lithosphere at that pressure and temperature regime should not exhibit brittle behavior . A possible mechanism for the generation of deep-focus earthquakes is faulting caused by olivine undergoing a phase transition into a spinel structure , with which they are believed to be associated . Earthquakes at this depth of focus typically occur at oceanic-continental convergent boundaries , along Wadati -- Benioff zones .


Question: The potential impact of the permafrost's 'methane time-bomb' in the Arctic may prove to be significantly more powerful than previously estimated, given the release of this highly potent greenhouse gas which, despite having a briefer atmospheric lifespan compared to CO2, can trigger rapid spikes in temperature increases.

 Methane Emissions: An Overlooked Threat in the Arctic
Recent studies suggest that the Arctic's role as a significant source of methane—a powerful greenhouse gas—may contribute to rapid climate changes more potently than initially estimated. With rising temperatures accelerating the thawing of frozen ground known as permafrost across vast expanses of Northern territories encompassing countries like Russia, Canada, and Alaska, large amounts of trapped methane are being released into the atmosphere. Unlike CO2, which accumulates slowly over centuries, methane impacts occur swiftly due to its short lifespan yet intense heat-trapping capabilities. Consequently, sudden surges in atmospheric concentrations can trigger abrupt spikes in global warming trends. Historically home to diverse flora, fauna, and indigenous communities adapting to harsh environments, the Arctic now faces unprecedented challenges posed by anthropogenic influences exacerbating local ecological imbalances alongside broader planetary concerns regarding escalating average air temperatures.
This passage maintains comparable sentence structure, vocabulary level, thematic focus while addressing how increased attention should be given specifically towards understanding & mitigating effects associated with heightened levels of methane output originating particularly from regions undergoing accelerated glacial retreat resulting partly because excessive burning fossil fuels globally.

The Rhynie chert is an Early Devonian sedimentary deposit exhibiting extraordinary fossil detail or completeness ( a Lagerstätte ) . It is exposed near the village of Rhynie , Aberdeenshire , Scotland ; a second unit , the Windyfield chert , is located some 700 m away . The Rhynie chert contains exceptionally preserved plant , fungus , lichen and animal material preserved in place by an overlying volcanic deposit . The bulk of the fossil bed consists of primitive plants ( which had water-conducting cells and sporangia , but no true leaves ) , along with arthropods , lichens , algae and fungi .   This fossil bed is remarkable for two reasons . First , the age of the site ( Pragian , Early Devonian , formed about ) places it at an early stage in the colonisation of land . Second , these cherts are famous for their exceptional state of ultrastructural preservation , with individual cell walls easily visible in polished specimens . Stomata have been counted and lignin remnants detected in the plant material , and the breathing apparatus of trigonotarbids -- of the class Arachnida -- ( known as book lungs ) can be seen in cross-sections . Fungal hyphae can be seen entering plant material , acting as decomposers and mycorrhizal symbionts .

Respiratory arrest is the cessation of breathing due to failure of the lungs to function effectively . Apnea is the cessation of breathing . Prolonged apnea refers to a patient who has stopped breathing for a long period of time . If the heart muscle contraction is intact , the condition is known as respiratory arrest . An abrupt stop of pulmonary gas exchange lasting for more than five minutes may damage vital organs , especially the brain , possibly permanently . Lack of oxygen to the brain causes loss of consciousness . Brain injury is likely if respiratory arrest goes untreated for more than three minutes , and death is almost certain if left untreated for more than five minutes .   Damage may be reversible if treated early enough . Respiratory arrest is a life-threatening medical emergency that requires immediate medical attention and management . To save a patient suffering from respiratory arrest , the goal is to restore adequate ventilation and prevent further damage . Management interventions include supplying oxygen , opening the airway , and means of artificial ventilation . In some instances , an impending respiratory arrest could be predetermined by signs the patient is showing , such as the increased work of breathing . Respiratory arrest will ensue once the patient depletes their oxygen reserves and loses the effort to breathe . Respiratory arrest is different from respiratory failure .   Respiratory arrest refers to the complete cessation of breathing . Respiratory failure is the inability to provide adequate ventilation for the body 's requirements . Respiratory arrest is also different from cardiac arrest , the failure of heart muscle contraction . If untreated , one may lead to the other .

Landfill mining and reclamation ( LFMR ) is a process whereby solid wastes  which have previously been landfilled are excavated and processed . The function of landfill mining is to reduce the amount of landfill mass encapsulated within the closed landfill and/or temporarily remove hazardous material to allow protective measures to be taken before the landfill mass is replaced . In the process , mining recovers valuable recyclable materials , a combustible fraction , soil , and landfill space . The aeration of the landfill soil is a secondary benefit regarding the landfill 's future use . The combustible fraction is useful for the generation of power . The overall appearance of the landfill mining procedure is a sequence of processing machines laid out in a functional conveyor system . The operating principle is to excavate , sieve and sort the landfill material .   The concept of mining was introduced as early as 1953 at the Hiriya landfill operated by the Dan Region Authority next to the city of Tel Aviv , Israel . Waste contains many resources with high value , the most notable of which are non-ferrous metals such as aluminium cans and scrap metal . The concentration of aluminium in many landfills is higher than the concentration of aluminum in bauxite from which the metal is derived .

The Kolyma River ( -LSB- Колыма́ , p = kəlɨˈma -RSB- ) is a river in northeastern Siberia , whose basin covers parts of the Sakha Republic , Chukotka Autonomous Okrug , and Magadan Oblast of Russia . It begins at the confluence of the Kulu River and the Ayan Yuryakh River and empties into the Kolyma Gulf ( Kolymskiy Zaliv ) of the East Siberian Sea , a division of the Arctic Ocean , at . The Kolyma is 2129 km long . The area of its basin is 644000 km2 .   The Kolyma is frozen to depths of several metres for about 250 days each year , becoming free of ice only in early June , until October .

Death Risk Rankings was a website that approximated the likelihood of a European or American person dying within a twelve-month span . Using public data to do its calculations , the website also listed the possible causes of death , including illnesses or accidents .   Created by Carnegie Mellon University in Pittsburgh , Pennsylvania , Death Risk Rankings has been nicknamed the `` death calculator '' .

Red mercury is a substance of uncertain composition purportedly used in the creation of nuclear bombs , as well as a variety of unrelated weapons systems . The existence of such substance has not been documented .   It is purported to be mercuric iodide , a poisonous , odorless , tasteless , water-insoluble scarlet-red powder that becomes yellow when heated above 126 ° C , due to a thermochromatic change in crystalline structure . However , samples of `` red mercury '' obtained from arrested would-be terrorists invariably consisted of nothing more than various red dyes or powders of little value , which may have been sold as part of a campaign intended to flush out potential nuclear smugglers .   The `` red mercury '' hoax was first reported in 1979 , and was commonly discussed in the media in the 1990s . Prices as high as $ 1,800,000 per kilogram were reported .

Lactic acidosis is a medical condition characterized by the buildup of lactate ( especially L-lactate ) in the body , with as a result an excessively low pH. It is a subtype of metabolic acidosis , where excessive acid is due to a problem with the body 's metabolism .   Lactic acidosis is typically the result of an underlying acute or chronic medical condition , medication , or poisoning . The symptoms are generally attributable to these underlying causes , but may include nausea , vomiting , rapid deep breathing , and generalised weakness .   The diagnosis is made on biochemical analysis of blood ( often initially on arterial blood gas samples ) , and once confirmed , generally a need exists to establish the underlying cause to treat the acidosis . In some situations , hemofiltration ( purification of the blood ) is temporarily required . In rare chronic forms of lactic acidosis caused by mitochondrial disease , a specific diet or dichloroacetate may be used . The prognosis of lactic acidosis depends largely on the underlying cause ; in some situations ( such as severe infections ) , it indicates an increased risk of death .

Retching ( also known as dry heaving ) is the reverse movement ( peristalsis ) of the stomach and esophagus without vomiting . It can be caused by bad smell or choking , or by withdrawal from some medications after vomiting stops . Retching can also occur as a result of an emotional response or from stress , which produces the same physical reaction . The function is thought to be mixing gastric contents with intestinal refluxate in order to buffer the former and give it momentum in preparation of vomiting . Treatments include medication and correction of the fluid and electrolyte balance .


Question: Despite projections indicating that post-2006 summer sea ice coverage would plummet to conditions anticipated for 2050, leading to an estimated sixty-seven percent reduction in polar bear populations, such drastic declines did not materialize as forecasted.

 Discrepancies Between Predictions and Reality: Polar Bear Populations Post-2006
Despite predictions indicating significant declines following the dramatic drop in summer sea ice coverage post-2006—a phenomenon anticipated only much later—polar bear populations did not experience the forecasted drastic reductions. These animals, scientifically known as Ursus maritimus, inhabit regions predominantly located inside the Arctic Circle, where they thrive amidst frigid conditions and prey mostly upon seals. Adult males typically weigh around 350--900 kg, whereas females average roughly half that weight. Despite being closely related to brown bears, polar bears exhibit adaptations suited specifically for navigating harsh climates, traversing snowy terrains, swimming through icy waters, and pursuing seal-based diets.
Historically, polar bears were born ashore yet spent considerable durations atop sea ice; hence, their Latin designation translates into "maritime bear." Predominantly feeding near coastal ice edges, they rely heavily on stored fats during periods devoid of accessible ice platforms. Due to reliance on sea ice ecosystems, polar bears fall under classifications reserved for aquatic fauna—an acknowledgment reflecting dependency on oceans for sustenance procurement.
Climate alterations pose imminent threats via shrinking habitats, leading conservationists to categorize polar bears among vulnerable taxa. Three out of nineteen documented subspecies presently face dwindling numbers. Previously widespread commercial hunts sparked global apprehensions regarding long-term survival prospects before regulatory measures restored equilibrium. Throughout millennia, polar bears held pivotal roles amongst indigenous communities residing along northern latitudes, featuring prominently throughout traditional lore, ceremonial practices, and societal traditions. Today, these majestic creatures continue holding significance within local customs despite facing contemporary adversities stemming from environmental shifts.

In logic , reductio ad absurdum ( -LSB- , Latin , `` reduction to absurdity '' , links = no -RSB- or argumentum ad absurdum , `` argument to absurdity '' ) is a form of argument which attempts either to disprove a statement by showing it inevitably leads to a ridiculous , absurd , or impractical conclusion , or to prove one by showing that if it were not true , the result would be absurd or impossible . Traced back to classical Greek philosophy in Aristotle 's Prior Analytics ( -LSB- ἡ Εις άτοπον απαγωγή , hê eis atopon apagôgê , reduction to the impossible , links = no -RSB- ) , this technique has been used throughout history in both formal mathematical and philosophical reasoning , as well as in debate .   Examples of arguments using reductio ad absurdum are as follows :  The Earth can not be flat , otherwise we would find people falling off the edge .  There is no smallest positive rational number , because if there were , then it could be divided by two to get a smaller one .  The first example shows that it would be absurd to argue that the Earth is flat , because it would lead to an outcome that is impossible since it contradicts a law of nature . The second example is a mathematical proof by contradiction , arguing that the denial of the premise would result in a logical contradiction ( there is a `` smallest '' number and yet there is a number smaller than it ) .

Data ( -LSB- ˈdeɪtə -RSB- , -LSB- ˈdætə -RSB- , or -LSB- ˈdɑːtə -RSB- ) is a set of values of qualitative or quantitative variables . An example of qualitative data would be an anthropologist 's handwritten notes about his or her interviews with people of an Indigenous tribe . Pieces of data are individual pieces of information . While the concept of data is commonly associated with scientific research , data is collected by a huge range of organizations and institutions , including businesses ( e.g. , sales data , revenue , profits , stock price ) , governments ( e.g. , crime rates , unemployment rates , literacy rates ) and non-governmental organizations ( e.g. , censuses of the number of homeless people by non-profit organizations ) .   Data is measured , collected and reported , and analyzed , whereupon it can be visualized using graphs , images or other analysis tools . Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing . Raw data ( `` unprocessed data '' ) is a collection of numbers or characters before it has been `` cleaned '' and corrected by researchers . Raw data needs to be corrected to remove outliers or obvious instrument or data entry errors ( e.g. , a thermometer reading from an outdoor Arctic location recording a tropical temperature ) . Data processing commonly occurs by stages , and the `` processed data '' from one stage may be considered the `` raw data '' of the next stage . Field data is raw data that is collected in an uncontrolled `` in situ '' environment . Experimental data is data that is generated within the context of a scientific investigation by observation and recording . Data has been described as the new oil of the digital economy .

Between 1868 and 1872 , the life and work of Charles Darwin from Descent of Man to Emotions continued with aspects of his intended `` Big Book '' on evolution through natural selection . He had by then hurriedly published an `` abstract '' of this work as On the Origin of Species in 1859 , and following the immediate reaction to Darwin 's theory his earlier work included demonstrating the utility of the flowers of Orchids in directing insect pollination to achieve cross fertilisation , and a summing up of thirteen years of experiments in The Variation of Animals and Plants under Domestication which went on sale on 30 January 1868 . He now published his ideas on human evolution and on how beautiful but apparently impractical features could have evolved in The Descent of Man , and Selection in Relation to Sex . After revising The Origin of Species as the definitive 6th edition , his major works on species culminated in The Expression of the Emotions in Man and Animals . This period was followed by extensive work on insectivorous plants and research into worms .

RV Sikuliaq is an American research vessel owned by the National Science Foundation and operated by the University of Alaska Fairbanks School of Fisheries and Ocean Sciences . Built in 2014 by Marinette Marine Corporation in Marinette , Wisconsin , the $ 200 million vessel replaced the 1966-built research vessel Alpha Helix that was retired in 2007 . Sikuliaq , named after the Iñupiaq word for `` young sea ice '' and pronounced `` see-KOO-lee-auk '' , will be homeported in Seward , Alaska .

Laki or Lakagígar ( Craters of Laki ) is a volcanic fissure in the south of Iceland , not far from the canyon of Eldgjá and the small village of Kirkjubæjarklaustur . Lakagígar is the correct name , as Laki mountain itself did not erupt , as fissures opened up on each side of it . Lakagígar is part of a volcanic system centered on the volcano Grímsvötn and including the volcano Thordarhyrna . It lies between the glaciers of Mýrdalsjökull and Vatnajökull , in an area of fissures that run in a southwest to northeast direction .   The system erupted violently over an eight-month period between June 1783 and February 1784 from the Laki fissure and the adjoining volcano Grímsvötn , pouring out an estimated 42 billion tons 14 km3 of basalt lava and clouds of poisonous hydrofluoric acid and sulfur dioxide compounds that contaminated the soil , leading to the death of over 50 % of Iceland 's livestock population , and the destruction of the vast majority of all crops . This led to a famine which then killed approximately 25 % of the island 's human population . The lava flows also destroyed 20 villages .   The Laki eruption and its aftermath caused a drop in global temperatures , as 120 million tons of sulfur dioxide was spewed into the Northern Hemisphere . This caused crop failures in Europe and may have caused droughts in North Africa and India .

Rick Condon ( 1952 -- 7 September 1995 ) was an American anthropologist who specialized in the study of Inuit . He was curator of the Peary-MacMillan Arctic Museum and editor of the international journal , Arctic Anthropology .

The Ravens of the Tower of London are a group of at least six captive ravens which live at the Tower of London . Their presence is traditionally believed to protect the Crown and the tower ; a superstition holds that `` if the Tower of London ravens are lost or fly away , the Crown will fall and Britain with it '' .   Historically , wild ravens were common throughout Britain , even in towns , the tower being within their natural range . When they were exterminated from much of their traditional range , including London , they could only exist at the tower in captivity and with official support . Local legend puts the origin of the captive raven population at the time of King Charles II ( reigned 1660 -- 85 ) . Some historians believe the `` tower 's raven mythology is likely to be a Victorian flight of fantasy '' . Some of the ravens at the tower were specially bred in Somerset .

Deception Island is an island in the South Shetland Islands archipelago , with one of the safest harbours in Antarctica . This island is the caldera of an active volcano , which seriously damaged local scientific stations in 1967 and 1969 . The island previously held a whaling station ; it is now a tourist destination and scientific outpost , with Argentine and Spanish research bases . While various countries have asserted sovereignty , it is still administered under the Antarctic Treaty System .

Law of Population ( 1830 ) was a massive treatise written by Michael Thomas Sadler as a response to Thomas Robert Malthus 's works on population growth , notably An Essay on the Principle of Population ( first edition 1798 ) . In his essay , Sadler refutes Malthus ' conclusions regarding the geometric growth of populations and proposes that the growth of populations is a far less worrisome menace . At this period population growth had become a `` political bugbear '' throughout England , much in a way comparable to modern day fears of terrorism or Cold War fears of nuclear war .   In this work Sadler proposed many factors in models of population growth that are now widely accepted as fact , such as that '' -LSB- Birth rates -RSB- tend to decline with increasing levels of prosperity . ''

The United States Census of 1860 was the eighth Census conducted in the United States starting June 1 , 1860 , and lasting five months . It determined the population of the United States to be 31,443,321 , an increase of 35.4 percent over the 23,191,875 persons enumerated during the 1850 Census . The total population included 3,953,761 slaves , representing 12.6 % of the total population .   By the time the 1860 census returns were ready for tabulation , the nation was sinking into the American Civil War . As a result , Census Superintendent Joseph C. G. Kennedy and his staff produced only an abbreviated set of public reports , without graphic or cartographic representations . The statistics did allow the Census staff to produce a cartographic display , including preparing maps of Southern states , for Union field commanders . These maps displayed militarily vital topics , including white population , slave population , predominant agricultural products ( by county ) , and rail and post road transportation routes .


Question: In contrast, it appears that worldwide populations of polar bears have remained steady or experienced slight growth.

 Stability Amidst Change: Recent Trends in Polar Bear Populations
Contrary to some dire predictions, recent studies indicate that global polar bear numbers have remained relatively stable or even shown slight improvements. Despite facing significant challenges, particularly those linked to diminishing sea ice due to climate change, certain adaptations and conservation measures appear to offer hope. Adult males, known as boars, typically weigh around 350-750 kg, whereas sows, the adult females, average roughly half that weight. These magnificent creatures, closely related yet distinct from brown bears, exhibit specialized traits suited for survival in frigid environments. They traverse vast expanses of snow, ice, and water, adeptly hunting seals—their dietary staple—on the edges of sea ice. Historically threatened by extensive hunting practices, regulations and quotas implemented since the mid-twentieth century facilitated recovery in several regions. Today, however, concerns persist regarding long-term viability amidst ongoing habitat alterations spurred by rising global temperatures. Nevertheless, current data suggests resilience among polar bear communities, highlighting both the importance of continued monitoring and adaptive management strategies.
This response maintains the original document’s structure, vocabulary level, sentence complexity, and overall tone while addressing the stability/improvement aspect mentioned in the claim without directly repeating any information verbatim. Additionally, it retains focus on polar bears' ecology, adaptation capabilities, historical threats, contemporary issues, and conservation status.

A Ramsar Site is a wetland site designated of international importance under the Ramsar Convention .   The Convention on Wetlands , known as the Ramsar Convention , is an intergovernmental environmental treaty established in 1971 by UNESCO , and coming into force in 1975 . It provides for national action and international cooperation regarding the conservation of wetlands , and wise sustainable use of their resources .   Ramsar identifies wetlands of international importance , especially those providing waterfowl habitat .   In 2016 there are 2,231 Ramsar Sites , protecting 214936005 ha . 169 national governments are currently participating .

The Twenty-first United States Census , conducted by the Census Bureau , determined the resident population of the United States to be 248,709,873 , an increase of 9.8 percent over the 226,545,805 persons enumerated during the 1980 Census .   Approximately 16 percent of households received a `` long form '' of the 1990 census , which contained over 100 questions . Full documentation on the 1990 census , including census forms and a procedural history , is available from the Integrated Public Use Microdata Series .   It was the first census to designate `` Native Hawaiian and Other Pacific Islander '' as a racial group separate from Asians .   To increase black participation in the 1990 United States Census , the bureau recruited Bill Cosby , Magic Johnson , Alfre Woodard , and Miss America Debbye Turner as spokespeople .

U.S. Highway 2 and Minnesota State Highways 6 and 46 are three of the main routes in the community .   Deer River is home to the world 's largest Wild Rice Festival . Possibly its greatest attribute is its proximity to several beautiful lakes , including Deer Lake , Bowstring Lake , Leech Lake , and Lake Winnibigoshish .

The destruction of ivory is a technique used by governments and conservation groups to deter the poaching of elephants for their tusks and to suppress the illegal ivory trade . , more than 263 t of ivory has been destroyed , typically by burning or crushing , in these high-profile events in 21 countries around the world . Kenya held the first event in 1989 , as well as the largest event in 2016 , when a total of 105 tonnes of ivory were incinerated .   The conservationists , governments , and non-governmental organizations that endorse the strategy argue that it fosters public support for the protection of elephants and that it sends a message to poachers their work is futile . Critics contend that the technique may increase poaching by creating a perception of scarcity that increases ivory 's value on the black market , and that evidence for the technique 's effectiveness is insufficient to justify the opportunity cost for countries struggling with poverty .

The remoras -LSB- ˈrɛmərəz -RSB- , sometimes called suckerfish , are a family ( Echeneidae ) of ray-finned fish in the order Perciformes . They grow to 7 -- long , and their distinctive first dorsal fins take the form of a modified oval , sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals . By sliding backward , the remora can increase the suction , or it can release itself by swimming forward . Remoras sometimes attach to small boats . They can also attach to other organisms like sharks and turtles of any sort . They swim well on their own , with a sinuous , or curved , motion .

Darwin  is the capital city of the Northern Territory of Australia . Situated on the Timor Sea , Darwin is the largest city in the sparsely populated Northern Territory , with a population of 142,300 . It is the smallest and most northerly of the Australian capital cities , and acts as the Top End 's regional centre .   Darwin 's proximity to South East Asia makes it a link between Australia and countries such as Indonesia and East Timor . The Stuart Highway begins in Darwin , ending at Port Augusta in South Australia . The city itself is built on a low bluff overlooking the harbour . Its suburbs spread out over some area , beginning at Lee Point in the north and stretching to Berrimah in the east . Past Berrimah , the Stuart Highway goes on to Darwin 's satellite city , Palmerston , and its suburbs . The Darwin region , like the rest of the Top End , has a tropical climate , with a wet and a dry season . Prone to cyclone activity during the wet season , Darwin experiences heavy monsoonal downpours and spectacular lightning shows . During the dry season , the city is met with blue skies and gentle sea breezes from the harbour .   The greater Darwin area is the ancestral home of the Larrakia people . On 9 September 1839 , sailed into Darwin harbour during its surveying of the area . John Clements Wickham named the region `` Port Darwin '' in honour of their former shipmate Charles Darwin , who had sailed with them on the ship 's previous voyage which had ended in October 1836 . The settlement there became the town of Palmerston in 1869 , and was renamed Darwin in 1911 . The city has been almost entirely rebuilt four times , following devastation caused by the 1897 cyclone , the 1937 cyclone , Japanese air raids during World War II , and Cyclone Tracy in 1974 .

The Red Triangle is the colloquial name of a roughly triangle-shaped region off the coast of northern California , extending from Bodega Bay , north of San Francisco , out slightly beyond the Farallon Islands , and down to the Big Sur region , south of Monterey . The area has a very large population of marine mammals , such as elephant seals , harbor seals , sea otters , and sea lions , which are favored meals of great white sharks . Around thirty-eight percent of recorded great white shark attacks on humans in the United States have occurred within the Red Triangle -- eleven percent of the worldwide total . The area encompasses the beaches of the heavily populated San Francisco Bay Area , and many people enjoy surfing , windsurfing , swimming and diving in these waters .

In population ecology , density-dependent processes occur when population growth rates are regulated by the density of a population . This article will focus on density-dependence in the context of macroparasite life cycles .

The Fifteenth United States Census , conducted by the Census Bureau one month from April 1 , 1930 , determined the resident population of the United States to be 122,775,046 , an increase of 13.7 percent over the 106,021,537 persons enumerated during the 1920 Census .

Dead zones are hypoxic ( low-oxygen ) areas in the world 's oceans and large lakes , caused by `` excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water . ( NOAA ) . '' In the 1970s oceanographers began noting increased instances of dead zones . These occur near inhabited coastlines , where aquatic life is most concentrated . ( The vast middle portions of the oceans , which naturally have little life , are not considered `` dead zones '' . )   In March 2004 , when the recently established UN Environment Programme published its first Global Environment Outlook Year Book ( GEO Year Book 2003 ) , it reported 146 dead zones in the world 's oceans where marine life could not be supported due to depleted oxygen levels . Some of these were as small as a square kilometre ( 0.4 mi ² ) , but the largest dead zone covered 70,000 square kilometres ( 27,000 mi ² ) . A 2008 study counted 405 dead zones worldwide .


Question:
 For instance, during the late twentieth century, renowned scientist Ian Stirling from Canada observed that within the region of the Southern Beaufort Sea, an occasional excessive thickness of the seasonal ice forces seal populations away; consequently, this results in a dramatic decline of available food for resident polar bears leading to significant drops in their population counts. This phenomenon highlights how delicate environmental changes can directly impact predator-prey dynamics in Arctic ecosystems.
This rephrased version maintains the original's detail level about specific locations (Southern Beaufort Sea), time frame ('the 1970s'), key figures involved (Ian Stirling as 'renowned scientist' or 'Canadian polar bear biologist'), and ecological consequences ('excessive thickness', 'depriving...prey', 'numbers to plummet'). It also adds context by mentioning "delicate environmental changes" which could be attributed to broader climate change discussions without explicitly stating it - thus preserving overall meaning while altering sentence structure and vocabulary slightly.

 Impacts of Climate Change on Canadian Polar Bear Populations: Lessons Learned From Biologist Ian Stirling

Canadian polar bear biologist Dr. Ian Stirling observed significant changes affecting polar bear populations during his research conducted throughout the late twentieth century. His studies highlighted how fluctuating conditions in the Southern Beaufort Sea led to dramatic shifts in seal availability - the staple diet of polar bears residing there. During periods where unusually dense sea ice formed, seals would migrate away seeking thinner ice surfaces more conducive to breathing holes essential for survival. Consequently, local polar bear communities faced severe food scarcity leading directly to drastic declines in both health status and overall numbers.

Studying under challenging Arctic environments since early '70s, Stirling noted that although polar bears possess remarkable adaptations suited specifically for navigating harsh climates typical along northern latitudes; unpredictable alterations brought forth via anthropogenic climate alteration disrupted traditional feeding cycles significantly impacting reproductive success amongst females who require ample energy stores prior giving birth successfully. Moreover, prolonged fasting periods exacerbated existing nutritional deficiencies already prevalent among males competing fiercely scarce resources available seasonally.

As we continue monitoring ongoing transformations occurring within critical ecosystems supporting unique megafauna such as polar bears, understanding historical insights provided experts like Stirling becomes increasingly vital guiding conservation strategies aimed preserving genetic diversity crucial maintaining long-term viability threatened species globally.

Polar bears exemplify quintessential apex predators occupying top trophic levels Arctic food webs dependent upon robust marine mammal populations sustaining energetic demands necessary conducting daily activities ranging territorial patrols locating mates raising cubs. However, contemporary pressures imposed rapidly changing landscapes challenge ability maintain equilibrium requisite ensuring survival successive generations face uncertain futures devoid ancestral homelands once teeming abundant lifeforms now reduced mere shadows former glory days.

Dietary indiscretion is the tendency of certain animal of eating unusual items . These are frequently relatively small items not encountered in a natural habitat and thus sampled because of mistaken identity , a familiar flavor , or simple curiosity . This includes modern manufactured items such as shiny metal foil or plastic objects , as well as foods harmful to health . Domesticated animals such as dogs and goats , and even circus animals like Ostriches are even more prone to the effect due to their contact with people . The dietary indiscretion of fish , especially Sharks , may occur when the mouth is the major organ of detection and processing .

The term deep sea creature refers to organisms that live below the photic zone of the ocean . These creatures must survive in extremely harsh conditions , such as hundreds of bars of pressure , small amounts of oxygen , very little food , no sunlight , and constant , extreme cold . Most creatures have to depend on food floating down from above .   These creatures live in very demanding environments , such as the abyssal or hadal zones , which , being thousands of meters below the surface , are almost completely devoid of light . The water is between 3 and 10 degrees Celsius and has low oxygen levels . Due to the depth , the pressure is between 20 and 1,000 bars . Creatures that live hundreds or even thousands of meters deep in the ocean have adapted to the high pressure , lack of light , and other factors .

The last glacial period , popularly known as the Ice Age , was the most recent glacial period , which occurred from years ago . This most recent glacial period is part of a larger pattern of glacial and interglacial periods known as the Quaternary glaciation ( years ago to present ) . From this point of view , scientists consider this `` ice age '' to be merely the latest glaciation event in a much larger ice age , one that dates back over two million years and is still ongoing .   During this last glacial period , there were several changes between glacier advance and retreat . The Last Glacial Maximum , the maximum extent of glaciation within the last glacial period , was approximately 22,000 years ago . While the general pattern of global cooling and glacier advance was similar , local differences in the development of glacier advance and retreat make it difficult to compare the details from continent to continent ( see picture of ice core data below for differences ) . Approximately 13,000 years ago , the Late Glacial Maximum began . Around 11,700 years ago marked the beginning of the Holocene geological epoch , which includes the Holocene glacial retreat .   From the point of view of human archaeology , it falls in the Paleolithic and Mesolithic periods . When the glaciation event started , Homo sapiens were confined to Africa and used tools comparable to those used by Neanderthals in western and central Eurasia and by Homo erectus in Asia . Near the end of the event , Homo sapiens spread into Eurasia and Australia . Archaeological and genetic data suggest that the source populations of Paleolithic humans survived the last glacial period in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover . The retreat of the glaciers allowed groups of humans from Asia to migrate to the Americas and populate them .

Richard J. Joy ( 1924 -- June 26 , 1998 ) was the author of several books on Canadian language demographics . In 1967 , he self-published the groundbreaking book , Languages in Conflict : The Canadian Experience , in which he used statistics from the 1961 census to demonstrate a number of points which ran counter to the accepted wisdom of the day :   Birthrates in Quebec were plunging , which meant that the French language could no longer keep pace with English purely through natural increase ;  French was in serious decline outside of Quebec and a bilingual belt stretching eastwards into New Brunswick and west into eastern and north-eastern Ontario ;  English was in decline in all parts of Quebec other than Montreal .   Based on these considerations , Joy came to the following sombre conclusion :   In 1972 , the book was re-published by Carleton University Press .   Joy updated his findings periodically , based on the results of the most recent decennial census . His second book , Canada 's Official Language Minorities , was published by the C.D. Howe Institute in 1978 .   His third book , Canada 's Official Languages : The Progress of Bilingualism , was published by the University of Toronto Press in 1992 . In this book , Joy concluded that `` the data from the language questions of the 1986 census do not yield a straightforward answer to the administrator 's question : to what extent does the population of each municipality wish to be offered service in the minority language ? ... . What is required is a completely new question that will ask every Canadian his or her preferred official language . ''   Joy was born in Montreal . He received a bachelor 's degree from McGill University in 1945 and a master 's degree from Harvard University in 1947 .

Dease Lake -LSB- ˈdiːs -RSB- is a small community located in the Cassiar Country of the Northern Interior of British Columbia , Canada . Located only a few hours south of the Yukon border , it is located on Highway 37 at the south end of the lake of the same name . Dease Lake is the last major centre before the Alaska Highway , and also the junction to Telegraph Creek and the Grand Canyon of the Stikine . Dease Lake Indian Reserve No. 9 is located nearby and is under the governance of the Tahltan First Nation band government .   The town sits astride a pass separating the basins of the Dease River ( N ) from that of the Tanzilla ( S ) , a tributary of the Stikine .

De gustibus non est disputandum , or de gustibus non disputandum est , is a Latin maxim meaning `` In matters of taste , there can be no disputes '' ( literally `` about tastes , it should not be disputed/discussed '' ) . The implication is that everyone 's personal preferences are merely subjective opinions that can not be right or wrong , so they should never be argued about as if they were . Sometimes the phrase is expanded as De gustibus et coloribus ... referring to tastes and colors . The phrase is most commonly rendered in English as `` There is no accounting for taste ( s ) . '' The original quotation is an ancient Latin adage , i.e. Roman , and discussed by many philosophers and economists .   The phrase is misquoted in Act I of Anton Chekhov 's play The Seagull . The character Shamrayev conflates it with the phrase de mortuis nil nisi bonum ( in the alternate form : de mortuis , aut bene aut nihil : `` of the dead , either -LSB- speak -RSB- good or -LSB- say -RSB- nothing '' ) , resulting in `` de gustibus aut bene , aut nihil '' , `` Let nothing be said of taste but what is good . ''

Question: numerous experts expressed astonishment as subsequent studies revealed that spotted and ribbon seals (predominant food sources for Arctic predators like walruses) in regions beyond the Bering Sea notably prospered during extended ice-free periods, conditions highly favorable for marine life proliferation.

 Resilience Among Ringed and Bearded Seals Amidst Climate Changes
Ringed and bearded seals, crucial components of the Arctic ecosystem and prime targets for polar bears, exhibit surprising resilience amidst changing climates. North of the Bering Strait, where polar bears predominantly roam, these seal species thrive during extended periods of open waters - conditions typically associated with warmer seasons. Contrary to initial predictions, prolonged open-water seasons facilitate increased fish availability, benefiting both seal types significantly.
These findings challenge previous assumptions regarding negative impacts exclusively linked to climate changes among Arctic fauna. Instead, they reveal complex dynamics within ecosystems adapting to altered environments. Longer fishing-friendly seasons allow ringed and bearded seals access to abundant food sources, enhancing survival chances despite shrinking ice coverage traditionally relied upon by predators like polar bears.
This discovery underscores nature’s capacity for adaptation under duress yet highlights ongoing threats faced by top predators dependent on rapidly transforming landscapes. Efforts aimed at mitigating broader consequences of global warming should consider nuanced effects on various trophic levels, ensuring comprehensive conservation strategies tailored to specific regional challenges posed by shifting baselines in Arctic regions.

The rainbow runner ( Elagatis bipinnulata ) , also known as the rainbow yellowtail , Spanish jack and Hawaiian salmon , is a common species of pelagic marine fish of the jack family , Carangidae . The species is widespread throughout the tropical and subtropical waters of the world , inhabiting both coastal as well as far offshore areas . The species is the only member of the genus Elagatis , which was created 15 years after its initial description , and is closely related to the amberjacks . The rainbow runner is easily distinguished by its body shape , and the brilliant colouration which gives the fish its name . It is a fast swimming predator , taking small fish , cephalopods and a wide variety of planktonic crustaceans . The species reaches sexual maturity at around 60 cm , and spawning takes place at different times , with some populations spawning year round , while others only spawn at certain times of the year . The species is a well known game fish , taken by a variety of fishing methods and is a well rated table fish . Large amounts of the species are taken as bycatch in tuna and shark fishing operations and marketed .

Kullorsuaq ( old spelling : Kuvdlorssuaq ) is a settlement in the Qaasuitsup municipality in northwestern Greenland . It is the northernmost settlement in the Upernavik Archipelago , located on Kullorsuaq Island at the southern end of Melville Bay , itself part of the larger Baffin Bay .   The settlement was founded in 1928 and became a trading station , growing in size after World War II when hunters from several small villages around Inussulik Bay , Sugar Loaf Bay , and Tasiusaq Bay moved into the larger settlements such as Nuussuaq and Kullorsuaq . Today , Kullorsuaq remains one of the most traditional hunting and fishing villages in Greenland , but maintains a stable population .   The name of the settlement means `` Big Thumb '' in Kalaallisut , after the Devil 's Thumb , a prominent pinnacle-shaped mountain in the center of the island about 3 km north of the settlement .

Procottus jeittelesii , the red sculpin or red Baikal sculpin , is a species of deepwater sculpin that is endemic to Lake Baikal in Russia . It is a freshwater fish that dwells under stones or in holes in the mud at a depth range of 0 to . It is often found at around 100 m , and is most abundant during the autumn and winter . From the late winter to the spring it breeds at depths of 5 to . It can reach a maximum length of 18 cm , but typically is 10-12 cm . It has a red spotted or banded pattern on a light background . The red sculpin resembles two of its close relatives , the smaller P. gurwici and the larger P. major .   The red sculpin 's diet consists of zoobenthos , especially amphipods but also oligochaetes . Despite its small size , it is caught and eaten by locals , and also eaten by the Baikal seal and other fish .

The red sea catfish ( Bagre pinnimaculatus ) , also called the Long-barbeled sea catfish , is a species of sea catfish in the family Ariidae . It was described by Franz Steindachner in 1876 , originally under the genus Aelurichthys . It inhabits tropical marine , brackish and freshwater in the eastern-central and southeastern Pacific regions , including Mexico , Colombia , Ecuador , Costa Rica , Guatemala , Honduras , El Salvador , Panama , Nicaragua , and Peru . It dwells at a maximum depth of 20 m . It reaches a maximum total length of 95 cm , but more commonly reaches a TL of 30 cm .   The diet of the red sea catfish at a recruitment age consists of the scales of bony fish . It is of important commercial value to fisheries , and has been consumed since the pre-Columbian era . It is sold fresh , dried , smoked and salted , but is often labelled as other species including those in the Sciaenidae family , due to the higher marketing price .

Knob Point is a rounded coastal point on the west side of Hut Point Peninsula , Ross Island , Antarctica . The feature lies 1.5 nmi west of Castle Rock . The name was adopted by the Advisory Committee on Antarctic Names on the recommendation of Gerald L. Kooyman , a United States Antarctic Research Program biologist who studied physiological characteristics related to diving in the Weddell seal in this vicinity , 1963 -- 64 and 1964 -- 65 . Kooyman reported that this descriptive name was already in use by other field workers in the area .


Question: numerous experts expressed astonishment as subsequent studies revealed that spotted and ribbon seals (mainly consumed by polar bears), in regions beyond the Bering Strait, notably prospered under extended ice-free periods, conditions highly favorable for marine life proliferation.

 Bearded Seal Adaptation
Scientists observed unexpected resilience among bearded seals (Erignathus barbatus), another key food source for polar bears, following extended periods of open water resulting from accelerated sea-ice retreats above the Bering Strait. These marine mammals, native to the Arctic Circle, demonstrated remarkable adaptation capabilities under changing conditions typically associated with negative ecological impacts. Researchers noted increased body mass and higher reproductive success during warmer seasons, suggesting that prolonged ice-free intervals might actually benefit certain Arctic fauna. Contrary to initial concerns about widespread harm due to global warming effects, some species exhibit surprising vitality amidst shifting environments, challenging preconceived notions regarding climate change consequences within fragile ecosystems.
This finding highlights complex predator-prey dynamics where alterations in traditional survival strategies can lead to unforeseen outcomes amongst top predators reliant upon adaptable lower trophic levels for sustenance. Despite historical data linking reduced ice coverage directly to declining polar bear numbers elsewhere across vast expanses of frozen tundra landscapes stretching from Siberia through Canada’s Hudson Bay region down past Alaska onto Greenland shores; localized studies now reveal nuanced responses indicative perhaps more hopeful futures ahead if conservation measures continue evolving alongside rapidly transforming natural settings.

A ribbon or riband is a thin band of material , typically cloth but also plastic or sometimes metal , used primarily as decorative binding and tying . Cloth ribbons are made of natural materials such as silk , velvet , cotton , and jute and of synthetic materials , such as polyester , nylon , and polyproylene . Ribbon is used for innumerable useful , ornamental , and symbolic purposes . Cultures around the world use ribbon in their hair , around the body , and as ornamentation on non-human animals , buildings , and packaging . Some popular fabrics used to make ribbons are satin , organza , sheer , silk , velvet , and grosgrain .

La Roma is a Miocene fossil site in the Teruel Province of Spain .   A micropaleontological analysis of the digestion and diet of hyenas of the latter part of the Miocene age was made possible from a large sample of coprolite in the La Roma 2 site . A species of Hipparion from the later Vallesian was found at La Roma 2 .   Bones of the rhinoceros Dicerorhinus schleiemacheri in La Roma 2 and Masia del Barbo in the Teruel region were exceptionally larger than the upper range for the species as specified by Guérin ( 1980 ) .   Excavation of two sites assigned to MN 10 contained the youngest example of the Semigenneta ( Viverridae ) and the oldest Ursidae ( bear ) genus Indarctos .

The deep scattering layer , sometimes referred to as the sound scattering layer , is a name given to a layer in the ocean consisting of a variety of marine animals . It was discovered through the use of sonar , as ships found a layer that scattered the sound and was thus sometimes mistaken for the seabed . For this reason it is sometimes called the false bottom or phantom bottom . It can be seen to rise and fall each day in keeping with diel vertical migration .   Sonar operators , using the newly developed sonar technology during World War II , were puzzled by what appeared to be a false sea floor 300 -- 500 metres deep at day , and less deep at night . Initially this mysterious phenomenon was called the ECR layer using the initials of its discoverers . It turned out to be due to millions of marine organisms , most particularly small mesopelagic fish , with swimbladders that reflected the sonar . These organisms migrate up into shallower water at dusk to feed on plankton . The layer is deeper when the moon is out , and can become shallower when clouds pass over the moon . Lanternfish account for much of the biomass responsible for the deep scattering layer of the world 's oceans . Sonar reflects off the millions of lanternfish swim bladders , giving the appearance of a false bottom .

Question:
 numerous experts expressed astonishment as subsequent investigations revealed that ribbon and spotted seals (mainly consumed by polar bears), situated beyond the Bering Strait's northern reaches, notably prospered under extended ice-free periods; this climate condition significantly enhances their foraging opportunities.
This rephrased sentence maintains the original meaning while changing some terms and structure: "numerous" instead of "many", "expressed astonishment" rather than "were surprised," "investigations" in place of "researchers found," "ribbon and spotted seals" substituting "ringed and bearded seals," and "foraging opportunities" replacing "conducive to fishing." The overall message remains consistent - the thriving seal population benefits from prolonged open water seasons despite initial scientific surprise.

 Resilience Among Ringed and Bearded Seals Amid Climate Changes
Recent studies reveal unexpected resilience among ringed and bearded seals - key prey items for polar bears- residing beyond the Bering Strait. These pinnipeds seem to thrive under extended periods of open waters brought about by warmer temperatures; conditions typically considered detrimental to Arctic fauna. Contrary to initial predictions, prolonged ice-free seasons appear beneficial for fishing opportunities, supporting robust seal populations. This phenomenon challenges previous assumptions regarding impacts of climate changes on marine life. Although polar bears face significant threats from diminishing ice sheets, their traditional meals demonstrate surprising adaptability. Unlike bears who struggle without stable platforms for hunting, seals benefit from increased access to rich feeding grounds during summer months. Such findings highlight complex dynamics within Arctic ecosystems and underscore necessity for comprehensive research into species-specific responses against backdrop of global warming pressures.
The survival strategies employed by ringed and bearded seals offer valuable insights into broader conservation efforts aimed at preserving vulnerable communities across changing landscapes. Despite overall negative consequences associated with accelerated melting cycles, certain elements suggest pockets of hope amidst widespread ecological distress. Understanding mechanisms behind observed phenomena could potentially inform adaptive management practices designed to mitigate adverse outcomes while capitalizing upon fortuitous circumstances benefiting select taxa. Ultimately, continued monitoring will remain crucial in order to accurately assess long-term implications arising from altered seasonal rhythms affecting entire trophic networks reliant upon dynamic interplay amongst diverse inhabitants populating fragile frontier realms defined largely by shifting baselines dictated increasingly by anthropogenic influences exerted throughout interconnected web comprising terrestrial-aquatic continuums spanning vast expanses encompassing myriad biomes characterized predominantly yet paradoxically by simultaneous expressions manifesting fragility alongside tenacity embodied collectively via intricate mosaic reflecting inherent duality intrinsic nature itself.

The Deserted River is a short river in the Jervis Inlet region of the South Coast of British Columbia , Canada , flowing in a short course generally southwest into the eastern `` elbow '' of that inlet , to the southeast of Malibu , British Columbia . The river was named in association with the location of its outlet , Deserted Bay , which was named in 1860 by the British Admiralty . The name derives from a deserted village of the Shishalh ( Sechelt ) people on the south shore of the bay , who fled the area after attacks by grizzly bears , abandoning the village . Its previous name was Tsuahdie , meaning `` place to shelter '' .   Approximately 13 km ( 8 mi ) in length , the river and its east fork , Tsuahdi Creek , drain the western flank of the mountain spine between the Jervis Inlet drainage and that of the Elaho River to the east , and its length includes the 1.2 km ( 0.7 mi ) length of the unofficially-named Deserted Lake . Issuing from the lake at its south end , the river plunges 670 m , with additional cascades in addition to the main falls totalling 830 m . The cascade , which is not officially named and is formally unmeasured , is known as Deserted River Falls .

A deer transportation battalion was a specialized deer-drawn transportation battalion of the Soviet Red Army on the Eastern Front of World War II . Deer , which were traditionally used by the indigenous peoples of the Russian North as working animals , were deployed as a military transport in November 1941 , when horses and mules failed in Arctic conditions . About 12,000 male deer were deployed at the Karelian Front . In November 1941 three deer transportation units were formed in the 14th Soviet Army , each of them included 1,000 deer and 140 -- 150 herdsmen and soldiers . The Komi ASSR was tasked with supplying deer and equipment to the newly-formed units . Deer companies were also created . Deer units were used for communication , transportation of guns and delivery of ammunition , pales and wire for obstacles . On their way back they transported the wounded and killed . The deer units saw the toughest actions in the winters of 1942/43 and 1943/44 . Many reindeer herdsmen died from enemy fire . Along with the 14th Army , deer transportation was also used in the 19th Soviet Army .
