This book was released on 2021-06-02 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the marine mammalian groups the Otariidae and the Odobenidae, otherwise known as fur seals, sea lions and the walrus. In 30 chapters, more than 60 authors from 30 institutions and 13 nationalities, discuss a broad suite of topics from maternal care and mating behavior, through play, cognition and personality, to adaptation to life in the Anthropocene. The authors explore the behaviors that have allowed these semi-aquatic mammals to thrive in the marine realm. Many populations have recovered following historical decimation, with interesting evolutionary consequences which are explored. Detailed, selected, individual species descriptions are also provided, showcasing the behavioral diversity of this engaging, adaptive and highly successful group of marine mammals.

This book was released on 2003-04-04 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: For an unknown reason, the Steller sea lion population in Alaska has declined by 80% over the past three decades. In 2001, the National Research Council began a study to assess the many hypotheses proposed to explain the sea lion decline including insufficient food due to fishing or the late 1970s climate/regime shift, a disease epidemic, pollution, illegal shooting, subsistence harvest, and predation by killer whales or sharks. The report's analysis indicates that the population decline cannot be explained only by a decreased availability of food; hence other factors, such as predation and illegal shooting, deserve further study. The report recommends a management strategy that could help determine the impact of fisheries on sea lion survival-establishing open and closed fishing areas around sea lion rookeries. This strategy would allow researchers to study sea lions in relatively controlled, contrasting environments. Experimental area closures will help fill some short-term data gaps, but long-term monitoring will be required to understand why sea lions are at a fraction of their former abundance.

Bigg and published by Fisheries and Oceans, Scientific Information and Publications Branch. This book was released on 1985 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial censuses were undertaken for Steller sea lions (Eumetopias jubatus) and California sea lions (Zalophus californianus) during 1971-84, and a review was made of published and unpublished data on numbers seen and numbers killed since 1913. These data were used to describe the location of haulout sites, season of occupation at haulout sites, regional movement patterns, and trends in numbers seen for each species during this century.

Download or read book The Bering Sea Ecosystem written by Committee on the Bering Sea Ecosystem and published by National Academies Press. This book was released on 1996-04-22 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.
