Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game (ADF&G) has been monitoring the health and status of ringed seals (Phoca hispida) in Alaska since 1960 by collecting information and samples from the Alaska Native subsistence harvest. This monitoring program is especially important because agencies are unable to overcome the logistical and sampling constraints necessary to estimate seal abundance in remote, ice covered waters. As such, reliable estimates of ringed seal abundance or population trend are lacking. Retrospective data analyses from this monitoring program allow us to examine how parameters that affect population size and status may vary in time and how current conditions compare with past conditions. Parameters we monitor that are indicative of population health or status include growth rate, body condition, diet, age distribution, sex ratio, age of maturation, and pregnancy rate. Since 2000, ADF&G has also conducted surveys for local knowledge and hunter preferences and analyzed tissue samples for contaminants and disease. All of these collections rely on the cooperation of coastal subsistence communities. Villages that have participated in the sampling program span the region from Hooper Bay in the Bering Sea to Kaktovik in the Beaufort Sea, including islands in the Bering Sea; an area that encompasses most of the range of ringed seals in Alaska.

Download or read book A Little Less Arctic written by Steven H. Ferguson and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.

This book was released on 2019-01-11 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Law Library presents the complete text of the Endangered and Threatened Species - Threatened Status for Arctic, Okhotsk, and Baltic Subspecies of Ringed Seal and Endangered Status (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, NMFS, issue a final determination to list the Arctic (Phoca hispida hispida), Okhotsk (Phoca hispida ochotensis), and Baltic (Phoca hispida botnica) subspecies of the ringed seal (Phoca hispida) as threatened and the Ladoga (Phoca hispida ladogensis) subspecies of the ringed seal as endangered under the Endangered Species Act (ESA). We will propose to designate critical habitat for the Arctic ringed seal in a future rulemaking. To assist us in this effort, we solicit information that may be relevant to the designation of critical habitat for Arctic ringed seals. In light of public comments and upon further review, we are withdrawing the proposed ESA section 4(d) protective regulations for threatened subspecies of the ringed seal because we have determined that such regulations are not necessary or advisable for the conservation of the Arctic, Okhotsk, or Baltic subspecies of the ringed seal at this time. Given their current population sizes, the long-term nature of the primary threat to these subspecies (habitat alteration stemming from climate change), and the existing protections under the Marine Mammal Protection Act, it is unlikely that the proposed protective regulations would provide appreciable conservation benefits. This ebook contains: - The complete text of the Endangered and Threatened Species - Threatened Status for Arctic, Okhotsk, and Baltic Subspecies of Ringed Seal and Endangered Status (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure

Download or read book Ethology and Behavioral Ecology of Phocids written by Daniel P. Costa and published by Springer Nature. This book was released on 2022-03-17 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phocid (or earless or true) seals are ecologically diverse, occupying habitats from the tropics to the poles in marine and freshwater and feeding on anything from tiny zooplankton to other marine mammals. There are 18 species of phocid seals, the smallest species (ringed seal) is more than 20 times smaller than the largest (southern elephant seal), with marked sexual dimorphism present in some species. This book examines the behavior, ecology, and physiology that allow phocid seals to inhabit such a wide range of habitats. The book is composed of 16 chapters written by 37 authors from 8 countries. The book first describes the general patterns of phocid behavior, followed by descriptions of what is known about well-studied species. We have taken a holistic approach, focusing not only on the behaviors themselves but also on the factors that constrain the expression of behavior and the proximate mechanisms driving behavior. In many cases, the chapters represent collaborations between well-established researchers and early-mid career individuals who bring new perspectives to help carry the field of phocid behavioral ecology well into the future.

Available in PDF, EPUB and Kindle. Book excerpt: The Pacific Arctic region is experiencing rapid sea ice retreat, seawater warming, ocean acidification and biological response. Physical and biogeochemical modeling indicates the potential for step-function changes to the overall marine ecosystem. This synthesis book was coordinated within the Pacific Arctic Group, a network of international partners working in the Pacific Arctic. Chapter topics range from atmospheric and physical sciences to chemical processing and biological response to changing environmental conditions. Physical and biogeochemical modeling results highlight the need for data collection and interdisciplinary modeling activities to track and forecast the changing ecosystem of the Pacific Arctic with climate change.
