This book was released on 2022-07-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Download or read book Marine Mammals and the Exxon Valdez written by Thomas R. Loughlin and published by . This book was released on 1994 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oil spill disaster that occurred when the Exxon Valdez ran aground has become part of the iconography of ecological disaster. This book synthesizes confidential data, recently released by the US government, concerning the effects of this spill on marine mammals (ie. sea otters, harbour seals, killer whales and humpback whales). Many of the contributors were on site within 24 hours of the spill and their results establish a baseline worst case scenario. These data should assist marine biologists, pathologists, toxicologists, environmentatlists, engineers, and coastal planners in assessing the nature of this disaster.

This book was released on 2007-03-14 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakersâ€"three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the National Science Foundation's PALMER, which is dedicated solely to scientific research. Today, the POLAR STAR and the POLAR SEA are at the end of their service lives, and a lack of funds and no plans for an extension of the program has put U.S. icebreaking capability at risk. This report concludes that the United States should continue to support its interests in the Arctic and Antarctic for multiple missions, including maintaining leadership in polar science. The report recommends that the United States immediately program, budget, design, and construct two new polar icebreakers to be operated by the U.S. Coast Guard. The POLAR SEA should remain mission capable and the POLAR STAR should remain available for reactivation until the new polar icebreakers enter service. The U.S. Coast Guard should be provided sufficient operations and maintenance budget to support an increased, regular, and influential presence in the Arctic, with support from other agencies. The report also calls for a Presidential Decision Directive to clearly align agency responsibilities and budgetary authorities.

Available in PDF, EPUB and Kindle. Book excerpt: "A major landmark contribution to fisheries science and fish ecology. Rockfish populations are in a severe decline throughout the Northeastern Pacific, and the need for a deep understanding of their biology, ecology, and management has never been more critical. This book addresses all aspects of our current knowledge of this diverse and interesting group of groundfish species, and it is written clearly and with humor. An outstanding work!"--Larry G. Allen, California State University, Northridge "Quite simply the best account ever of the fascinating, diverse, and valuable rockfishes. If you are interested in the marine fishes of the Pacific Coast, you need this book."--Peter B. Moyle, author of Inland Fishes of California
Download or read book Governing Complexity in the Arctic Region written by Mathieu Landriault and published by Routledge. This book was released on 2019-10-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines emerging forms of governance in the Arctic region, exploring how different types of state and non-state actors promote and support rules and standards. The authors argue that confining our understandings of Arctic governance to Arctic states and a focus on the Arctic Council as the primary site of circumpolar governance provides an incomplete picture. Instead, they embrace the complexity of governance in the Arctic by systematically analyzing and comparing the position, interventions, and influence of different actor groups seeking to shape Arctic political and economic outcomes in multiple sites of Arctic politics, both formal and informal. This book assesses the potential that sub-national governments, corporations, civil society organizations, Indigenous peoples, and non-Arctic states possess to develop norms and standards to ensure a stable, rule-based Arctic region. It will be of interest to all scholars and students working in the fields of Arctic Sovereignty, Security Studies, Global Governance, and International Political Economy.
