Available in PDF, EPUB and Kindle. Book excerpt: More animals were seen in the water during the 1989 survey, but the proportion of animals in the water was not determined. [...] Instead of correcting only the counts from the south Ooglit islands for animals not hauled out, we also include the counts from the 3 additional haulouts surveyed at the time, and divided the combined total of hauled-out animals by 0.37 resulting in an abundance estimate of 12,119 animals (Table 6). [...] PBR estimates ranged from 129 animals using the 2010 abundance estimate of 10,439, a Rmax of 0.07, and a FR of 0.5 to a PBR of 385 animals using the 2011 abundance estimate of 14,093, a Rmax of 0.08 and FR = 1. PBR estimates using a third value for FR of 0.75 were intermediate (Table 7). [...] These counts or survey estimates of animals hauled out, are then adjusted for the proportion of animals that are thought to be in the water during the survey to obtain an estimate of abundance. [...] These methods differ in what they are estimating and in the types of adjustment factors that are appropriate to adjust the counts for the proportion of animals hauled out (Doniol-Valcroze et al.

Book excerpt: Four stocks of Atlantic Walrus (Odobenus rosmarus rosmarus) have been identified in Canada: South and East Hudson Bay; Hudson Bay-Davis Strait; Foxe Basin; and Baffin Bay. This report provides biological information on the walrus as well as information about annual harvests and resource status (including stock delineation, stock size, stock trends, and sustainable harvest rates). It also discusses management considerations.

Book excerpt: "Summarizes available information on distribution, numbers and exploitation of Atlantic walruses (Odobenus rosmarus rosmarus L.) for an assessment of their present status. The effects on walruses of various human activities other than hunting (e.g. disturbance, pollution, fishery interactions) are also evaluated."--Page 6.

Available in PDF, EPUB and Kindle. Book excerpt: These are, tentatively, the east and south Hudson Bay stock, the Hudson Bay-Davis strait stock, the Foxe Basin stock, and the Baffin Bay stock. [...] The ranges of the Hudson Bay-Davis Strait and the Baffin Bay stocks undoubtedly extend, or extended, to Greenland and these stocks may be shared by hunters there but there are no population estimates for these two stocks, and no strong evidence of their current connectedness. [...] Basic information is still lacking on the distribution, movements, and stock identity of walrus in Canada, information that is necessary to define the distribution of stocks to underpin regional allocations and sustainable yield estimates. [...] The distribution of walrus in South and East Hudson Bay was once continuous with western Hudson Strait (Richard and Campbell 1988) and may represent a part of this population (NAMMCO 1995). [...] Walrus range has contracted in the northeast corner of Hudson Bay (Richard and Campbell 1988) suggesting a separation between Hudson Strait walrus and those in south and east Hudson Bay.

Download or read book The Atlantic Walrus written by Xénia Keighley and published by Academic Press. This book was released on 2021-06-17 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic. This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies. Provides succinct overviews of the biology of the Atlantic Walrus (Odobenus rosmarus rosmarus) as well as human cultures within the North Atlantic Arctic and the surrounding region by consolidating research which until now has been scattered across fields and academic publications Editorial team of inter-disciplinary researchers ensuring the breadth, depth and integration of material covered throughout the volume Thirteen chapters, each authored by leading international researchers and experts on the Atlantic Walrus Considers the inter-relatedness and complexity of species biology, ecological change, human culture, and anthropogenic pressures onto the Atlantic Walrus, all while remaining accessible to readers from different disciplines or a more generalist audience Draws upon the latest methods in marine mammal and archaeological research Assesses historical management of the species, while also considering current and future conservation efforts in light of human activities and climate change Text supported by striking and insightful new maps and scientific illustrations, ideal for teaching and outreach

Download or read book Polar Bears written by IUCN/SSC Polar Bear Specialist Group. Working Meeting and published by IUCN. This book was released on 2006 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar arctic. Together with the previous 13 proceedings, they provide an historic record of international efforts in protecting, studying and managing polar bears. With recent documentation of how warmer arctic climate might affect the sea ice habitat of polar bears, the predictions of even warmer climate in the next decades, and documentation of effects on polar bears subpopulations, an evaluation of the red list status of polar bear subpopulations was followed by an increased conservation designation of vulnerable. In the complexity of possible interactions between climate change, local harvest, and in some areas high levels of pollutants, an increased level of international cooperation was advocated.
