Increasing abundance of bowhead whales in West Greenland. (1/6)

In April 2006, a dedicated survey of bowhead whales (Balaena mysticetus) was conducted on the former whaling ground in West Greenland to determine the current wintering population abundance. This effort included a double platform aerial survey design, satellite tracking of the movements of nine whales, and estimation of high-resolution surface time from 14 whales instrumented with time-depth recorders. Bowhead whales were estimated to spend an average of 24% (cv=0.03) of the time at or above 2m depth, the maximum depth at which they can be seen on the trackline. This resulted in a fully corrected abundance estimate of 1229 (95% CI: 495-2939) bowhead whales when the availability factor was applied and sightings missed by observers were corrected. This surprisingly large population estimate is puzzling given that the change in abundance cannot be explained by a recent or rapid growth in population size. One possible explanation is that the population, which demonstrates high age and sex segregation, has recently attained a certain threshold size elsewhere, and a higher abundance of mature females appears on the winter and spring feeding ground in West Greenland. This in combination with the latest severe reduction in sea ice facilitating access to coastal areas might explain the surprising increase in bowhead whale abundance in West Greenland.  (+info)

ABSTRACT: We describe a case series of benign hepatic fatty tumors in 10 subsistence-harvested bowhead whales. Microscopic features included lipomatous and myelolipomatous masses. Extensive atrophy and/or destruction of hepatic parenchyma was not observed. No other significant disease was present except in an animal with unrelated chronic pleuritis. Based on our longitudinal case series (1980-2016) which identified 1-2 hepatic lipomas and myelolipomas in landed whales annually at Barrow, Alaska (USA), since 2012, hepatic lipomas and myelolipomas are occasionally seen in hunter-harvested bowhead whales. A conservative estimate for the percentage of bowhead whales with hepatic fatty tumors in landed whales in Barrow from 2012 to 2016 was 6% (7/111). The pathogenesis and exact cell origin of these benign fatty tumors in bowhead whales is undetermined. Assessment of further cases is warranted to better define the tissue distribution and pathogenesis of these tumors in bowhead whale liver. ...

A bowhead whale is a slow swimmer, usually moving at about 2 to 4 mph (3 to 6.5 kph), and traveling alone or in small groups. It breaks ice as needed as it moves, particularly when it needs to come up for air. A bowhead will hide under ice when frightened. To feed, it opens its large mouth and filters prey through its baleen. Though a bowhead moves to warmer waters for the summer, it never leaves sub-Arctic waters. Mating starts in spring, and a bowhead male will sing to attract a mate. A female gives birth every three to six years, about 13 to 14 months after mating. A bowhead whale is born tail first. It is lighter-colored than an adult, and must swim to the surface, sometimes with its mothers help, to breathe. A bowhead baby drinks its mothers milk for about a year. A male bowhead is mature at about 11 years, and a female at over 15 ...

ABSTRACT: Interest in bowhead whale stock structure has been high due to the species extreme historical depletion, differential rates of recovery, the potential effects of climate change, and the need to set appropriate quotas for aboriginal hunts. We present an analysis of 42 linked and unlinked single nucleotide polymorphisms (SNPs) among 3 bowhead whale stocks and within the Bering/Chukchi/Beaufort Seas (BCB) stock, and compare results with previously published results of mtDNA control region sequences and 22 microsatellites. We performed tests of population structure (FST, χ2, STRUCTURE), population assignment, and estimates of effective population size (Ne), and evaluated different numbers of loci and samples to estimate the relative statistical power of SNPs and microsatellites. Results indicate that this number of SNPs provides similar power to microsatellites to detect low levels of differentiation (FST = 0.005−0.03) between bowhead populations with sample sizes of at least 20 per ...

Thomas Doniol-Valcroze, Steve Ferguson, Jean-François Gosselin, Jack Lawson and Kevin Hedges. Numerous Inuit communities across the Canadian Arctic hunt narwhals and bowhead whales for subsistence, economic and cultural reasons. Sustainability of these important harvesting activities relies on obtaining up-to-date estimates of population abundance. Obtaining such estimates, however, is challenging because of the vast geographic areas to cover, and difficult Arctic weather conditions. Moreover, narwhals exhibit site fidelity by returning to the same summering areas every year, and therefore each of these summer stocks has to be surveyed to provide estimates that are meaningful to local hunters.. The purpose of the High Arctic Cetacean survey, a large-scale aerial survey conducted in the eastern Canadian Arctic in August 2013, was to obtain new abundance estimates of the Baffin Bay narwhal population and the Eastern Canada-West Greenland bowhead whale population. The last estimates were ...

Todays Northwest Passage. The Lower Snake River Project received the outstanding water resources engineering project award for 1976 from ASCE. The lower 140-mile (225-km) reach of the Snake River from its mouth to the Idaho line has been developed with four dams: Ice Harbor, Lower Monumental, Little Goose, and Lower Granite. Reliable water transportation for towboat and barge is a reality now, reaching from the Pacific Ocean upstream on the Columbia and Snake Rivers for 465 miles (748-km) to Lewiston, Idaho. The unique features associated with development of the multipurpose project, the Lower Snake River Project, exemplify sound engineering decisions for some of the most complex structural, hydraulic, environmental, and geotechnical engineering problems.

The Effect of Inappropriate Calibration: Three Case Studies in Molecular EcologyThe Effect of Inappropriate Calibration: Three Case Studies in Molecular Ecology
Time-scales estimated from sequence data play an important role in molecular ecology. They can be used to draw correlations between evolutionary and palaeoclimatic events, to measure the tempo of speciation, and to study the demographic history of an endangered species. In all of these studies, it is paramount to have accurate estimates of time-scales and substitution rates. Molecular ecological studies typically focus on intraspecific data that have evolved on genealogical scales, but often these studies inappropriately employ deep fossil calibrations or canonical substitution rates (e.g., 1% per million years for birds and mammals) for calibrating estimates of divergence times. These approaches can yield misleading estimates of molecular time-scales, with significant impacts on subsequent evolutionary and ecological inferences. We illustrate this calibration problem using three case studies: avian speciation in the late Pleistocene, the demographic history of bowhead whales, and the Pleistocene

The bowhead whale also has a circumpolar Arctic distribution. It is a large, baleen whale (Mysticete) that can reach a length of 20 m and a weight of 75 tonnes. Two populations are recognized in the Canadian Arctic, which are separated by physical barriers (land and impassable ice). The Bering-Chukchi-Beaufort population summers in the Canadian Beaufort Sea, along the south and west coasts of Banks Island and west of Tuktoyaktuk Peninsula, as well as in Amundsen Gulf. In winter, the population is distributed in the western and central Bering Sea (additional information available here). The Eastern Canada-Western Greenland population summer in western Baffin Bay, the Canadian High Arctic, northern Foxe Basin, and northwestern Hudson Bay. Wintering occurs in areas with unconsolidated pack ice such as northern Hudson Bay, Hudson Strait, central Davis Strait, southern Baffin Bay, and off West Greenland (see the Species at Risk page for details). In recent years, the reduction of the summer ice has ...

By the middle of the nineteenth century, the New England port of New Bedford was among the ?ve richest cities in America. Its wealth was derived from a single source - whale oil, the "fossil fuel" of the early Industrial Revolution, providing light and lubrication to the burgeoning economy of young America. The New Bedford whaling ?eet was the most numerous, adventurous, and far-ranging in the world, setting off on voyages that often lasted for three or four years and extended as far as the Antarctic and Siberia.When the whalemen were not engaged in hunting whales or routine maintenance, some of their time was spent carving materials harvested from the whales themselves: the teeth and bones of sperm whales, baleen from right and bowhead whales, and walrus tusks acquired by barter from Native people in the Arctic. The resulting practical and decorative objects, often intricately carved and carefully crafted, would provide mementos and treasured souvenirs for loved ones back home, at voyage end. ...
Aboriginal whaling - WikipediaAboriginal whaling - Wikipedia
In the United States whaling is carried out by Alaska Natives from nine different communities in Alaska. The whaling programme is managed by the Alaska Eskimo Whaling Commission which reports to the National Oceanic and Atmospheric Administration. The commission includes eleven whaling communities who inhibit the Arctic Alaska coast: the Gambell, Savoonga, Wales, Little Diomede, Kicalina, Point Hope, Point Lay, Wainwright, Barrow, Nuiqsut, and Kaktovik.[4]. The hunt takes around 75 bowhead whales a year from a population of about 10,000 in Alaskan waters. Anti-whaling groups claim this hunt is not sustainable, though the IWC Scientific Committee, the same group that provided the above population estimate, projects a population growth of 3.2% per year. The hunt also took an average of one or two gray whales each year until 1996. The quota was reduced to zero in that year due to concerns about sustainability. The hunts are now allowed to take 744 gray whales between 2013-2018, but the maximum ...

This morning at 08:00 we landed at Gravneset in Trinity Bay at the head of Magdalenafjord. At one time Bowhead Whales and other species of whales were very numerous in this area. Two centuries of intensive whaling depleted the whale stock to the point where whaling was no longer practical. The landing site at Gravneset (grave headland) is beside a large ancient cemetery where 130 whalers from that epoch are buried. I wonder if the whalers that came here two or three hundred years ago appreciated the beauty of the region, or were they more intent on their arduous tasks and staying alive? From archeological evidence and historical records it seems the most common cause of death was disease and scurvy. Now, in the age of the computer when an interval of five years produces miraculous changes in technology it is difficult to contemplate what a whalers day-to-day life might have been like ...
Under Thin Ice: Climate Change in the ArcticUnder Thin Ice: Climate Change in the Arctic
The Arctic is a majestic world, home to wildlife rarely seen further south: bowhead whales, polar bears, narwhals and walruses. Life thrives on and under a legendary blanket of snow and ice, covering millions of square kilometres of land and ocean.. At the end of spring, when the sun shines 24 hours a day, life flourishes at the floe edge. Here, where ice meets open waters, living species gather for a feeding frenzy. In the Arctic, the entire polar web of life depends on the ebb and flow of ice.. But climate change is threatening this ecosystem. Temperatures are rising and ice is melting at an alarming rate. Since 1980, the film notes, the amount of summer ice cover has dropped by about 80 per cent. Diving with whales, walruses and polar bears, Heinerth and Cyr bring viewers into a majestic underwater world threatened by disappearing ice and rapid climate change..

Eco-Economy Indicators - Global Temperature - Past Decade the Hottest on Record | EPIEco-Economy Indicators - Global Temperature - Past Decade the Hottest on Record | EPI
Though temperatures are rising around the globe, some areas are warming faster than others, with the greatest warming taking place in the Arctic. Paleoclimate records from Arctic lakes, tree rings, and ice cores reveal that the past decade was the warmest of the past two millennia. Warming is amplified in the Arctic for a number of reasons, including the loss of the regions extensive snow and ice cover: as temperatures rise and light-reflecting ice melts, it is replaced by darker water, which absorbs more energy from the sun, thereby accelerating warming. In parts of the Arctic, average annual temperatures have increased by as much as 2-3 degrees Celsius (3.6-5.4 degrees Fahrenheit) since the 1950s. In 2007, Arctic summer sea ice shrank to its lowest extent on record, leaving the Northwest Passage completely ice-free for the first time in human memory. Then 2008 and 2009 brought the second and third lowest extent of Arctic summer ice on record ...

Genetic Mutation in Whale Eyes May Increase Mortality Risks, New Research Finds - Florida Tech NewsroomGenetic Mutation in Whale Eyes May Increase Mortality Risks, New Research Finds - Florida Tech Newsroom
MELBOURNE, FLA. - Scientists have found that a genetic mutation in the eyes of right whales that hampers their ability to see in bright light may make them more susceptible to fatal entanglements in fishing gear, one of the major causes of death for this critically endangered mammal.. The study of this whale species, which numbers less than 500 individuals remaining in the Western Atlantic Ocean, may also help scientists better understand how vision works in other mammals, including people.. Florida Institute of Technology doctoral student Lorian Schweikert and her adviser, Michael Grace, professor of neuroscience and senior associate dean of science, worked with Jeffry Fasick, an assistant professor of biology at the University of Tampa, to characterize this newly discovered mutation in Northern right whales and Bowhead whales. Their results suggest that this mutation may seriously harm the whales ability to visually avoid entanglement.. According to their new study, "Evolutionary Loss of Cone ...

The first part of the present study evaluated tissue concentrations of twelve essential and non-essential elements in four arctic marine mammal species important as subsistence resources to indigenous Alaskans. Species sampled included: bowhead whales, beluga whales, ringed seals, and polar bears. Concentrations of As, Cd, Co, Cu, Pb, Mg, Mn, Hg, Mo, Se, Ag, and Zn, were analyzed in liver, kidney, muscle, blubber, and epidermis (the latter in cetaceans only). Elements that were identified as having tissue concentrations, which in domesticated species would have been considered higher than normal and/or even toxic, were Cd, Hg, Ag, and Se. However, the concentrations of these elements were consistent with previous reports for arctic marine mammals. Remaining elements were at concentrations within normal ranges for domesticated species, although Cu was found frequently at concentrations that would be considered marginal or deficient in terrestrial domesticated animals. Across-species comparisons revealed

A newly published study is complicating one of most commonly held assumptions on the fate of Sir John Franklin and his doomed expedition for the Northwest Passage: that he and his crew slowly met their demise, in part, through lead poisoning.. Jennie Christensen, an environmental toxicologist who led a study submitted to the Journal of Archaeological Sciences, says John Hartnell, one of the three Franklin crewman buried on Beechey Island-a major source for the lead poisoning theory-actually had lead levels within a "healthy, normal range," contrary to earlier findings reported in the 1980s.. Christensen and her team based their conclusions on modern microscopic laser and X-ray scans of finger and toenail samples collected from Hartnells remains and interred at the Canadian Museum of History in Gatineau, Que., after receiving permission from Nunavuts Inuit Heritage Trust.. The real culprit for Hartnells demise: zinc deficiently from malnourishment, a condition that suppresses the immune system ...

Overland to Starvation Cove With the Inuit in Search of Franklin, 1878-1880 (Book) : Klutschak, Heinrich W. : In May 1845 Sir John Franklin sailed westward from England in search of the Northwest Passage and was never seen again. Some thirty-five years later, Heinrich Klutschak of Prague, artist and surveyor on a small expedition led by Lieutenant Frederick Schwatka of the 3rd US Cavalry Regiment, stumbled upon the grisly remains at Starvation Cove of the last survivors among Franklins men. Overland to Starvation Cove is the first English translation of Klutschaks account. A significant contribution to Canadian exploration history, it is also an important anthropological document, providing some of the earliest reliable descriptions of the Aivilingmiut, the Utkuhikhalingmiut, and the Netsilingmiut. But above all, it is a fascinating story of arctic adventure.
Making ecology count: a review of the why and how of molecular ecology |Making ecology "count": a review of the why and how of molecular ecology |
Its likely that everyone has been asked by either a friend or family member "What do you do?" Which, depending on what level of detail you shoot for, might be relatively straight forward. The follow-up question, however, can be a little trixie: "Why??". A recent review by Creer and colleagues gives a nice broad overview of molecular ecology, defines key terms, and highlights the main advances that new technology has afforded the field. From sampling to sequencing, this article briefly covers landmark moments that have laid the foundation for the advancement of molecular ecology and emphasizes the future potential of continuing to link traditional ecological approaches with sequence-based techniques.. ...

Computational Chemistry Highlights: October 2012Computational Chemistry Highlights: October 2012
If one defines nondynamic correlation as the significant contribution of several electronic configurations to the total energy of a system, it can be seen that this type of correlation becomes important for a number of chemically relevant situations, including the breaking of covalent bonds. Some of the methods typically used to recover nondynamic correlation include CASSCF and MRCI, with the common theme that they quickly become expensive in terms of computational cost, and that a degree of expertise is required in the choice of which orbitals and electrons to include in the active space of nondynamic correlation. The method proposed attempts to bypass these difficulties by carrying out a standard DFT calculation, then adding a correction for nondynamic correlation (with an empirical scale factor) via a CASCI calculation including a small set of orbitals in the active space. The authors suggest that this choice of orbitals can be automated, producing a computationally efficient black-box method ...

We introduce a new implementation of the coupled cluster method with single and double excitations tailored by the matrix product state wave functions (DMRG-TCCSD), which employs the local pair natural orbital (LPNO) approach. By exploiting locality in the coupled cluster stage of the calculation, we were able to remove some of the limitations that hindered the application of the canonical version of the method to larger systems and/or with larger basis sets. We assessed the accuracy of the approximation using two systems: tetramethyleneethane (TME) and oxo-Mn(Salen). Using the default cut-off parameters, we were able to recover over 99.7% and 99.8% of the canonical correlation energy for the triplet and singlet state of TME, respectively. In the case of oxo-Mn(Salen), we found that the amount of retrieved canonical correlation energy depends on the size of the complete active space (CAS)-we retrieved over 99.6% for the larger 27 orbital CAS and over 99.8% for the smaller 22 orbital CAS. The use ...
