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.
Download or read book Ethology and Behavioral Ecology of Sea Otters and Polar Bears written by Randall W. Davis and published by Springer. 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 Coastal Ecosystems Modelling and Conservation written by Marco Ortiz and published by Springer Nature. This book was released on 2020-12-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a collection of large-scale network-modeling studies on coastal systems in Latin America. It includes a novel description of the functioning of coastal complex ecosystems and also predicts how natural and human-made disturbances percolate through the networks. Coastal areas belong to the most populated ecosystems around the globe, and are massively influenced by human impacts such as shipping, mining, fisheries, tourism, pollution and human settlements. Even though many of these activities have facilitated socio-economic development, they have also caused a significant deterioration in natural populations, communities and ecosystems worldwide. Covering coastal marine ecosystems of Latin America such as the NE and SE Pacific, NW Atlantic and Caribbean areas, it discusses the construction of quantitative (Ecopath-Ecosim-Ecospace and Centrality of Node Sets) and semi-quantitative (Loop Analysis) multispecies trophic-network models to describe and assess the impacts of natural and human interventions like pelagic and benthic fishing as well as natural events such as El Niño, and La Niña. The book also features steady state (and/or near moving equilibrium) and dynamical models to support the management of exploited organisms, and applies and quantifies macroscopic indices, based on Ascendency (Ulanowicz) and Local Stability (Levins ́ Loop Analysis). Further, it discusses the determination of the Keystone Species Complex Index, which is a holistic extension of the classical concept of Keystone Species (Paine), offering novel strategies for conservation monitoring and management.

Book excerpt: Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.

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.

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.

This book was released on 2018-09-04 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the recent development and use of computer modeling and simulation as an important tool for understanding environmental and resource-based conflicts and for finding pathways for conflict resolution and cooperation. It introduces a new, innovative technique for using agent-based modeling (ABM) as a tool for better understanding environmental conflicts and discusses the application of agent-based modeling for the analysis of multi-agent interaction and conflict and demonstrates the natural interdisciplinary convergence. The authors explore numerous examples of environmental and resource conflicts around the world, as well as cooperative approaches for conflict resolution.
