Book Description
This paper provides background on populations of walrus in Canada, drawing most heavily on scientific literature but supplemented by resource-user knowledge. It summarizes information on walrus stock identity and the five postulated walrus management stocks in Canada (Maritime, South & East Hudson Bay, Hudson Bay-Davis Strait, Foxe Basin, Baffin Bay), population sizes & trends, mortality & productivity, walrus hunting regulations & harvest levels, the status of the walrus resource, sources of uncertainty in the data, and management & environmental considerations.

Book Description
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.

Book Description
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

Book Description
"The walrus, Odobenus rosmarus, is a circumpolar species of arctic and sub-arctic waters and is geographically isolated into three or more morphologically distinct groups. The Eastern Canadian Arctic and West Greenland group ranged as far south as Sable Island and the Gulf of St. Lawrence in historic times, but unrestricted commercial exploitation led to a serious decline in numbers and a withdrawal of the group to the more northern and inaccessible parts of its range. The advent of the rifle into the Eskimo economy with consequent wasteful methods of hunting caused further serious reductions in the walrus herds and necessitated the introduction of restrictive hunting measures." --
