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.
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.
Download or read book New POPs in Marine Mammals in Nordic Arctic and NE Atlantic Areas During Three Decades written by Maria Dam and published by Nordic Council of Ministers. This book was released on 2011-11-25 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals hold a special position in the hearts of people inhabiting Nordic Arctic areas and in coastal communities around the North Atlantic Ocean as they are an essential part of the diet and traditional life-style. However, marine mammals are in a particularly vulnerable position as regards environmental pollutants, because of the large fat stores in their bodies which serve as a "magnet" to a large number of persistent and toxic pollutants. A Nordic Council of Ministers supported collaboration between Norway, Denmark/Greenland, Faroe Island, Iceland and Sweden set out to look for possible trends in "new" contaminants in marine mammals in Nordic Arctic waters. The "new" contaminants in focus are the brominated flame retardants including the PBDEs, methoxylated PBDEs, perfluorinated compounds including the PFOS family, and polychlorinated naphthalenes. In addition, a subset of the samples was analysed for brominated dioxins and dibenzofurans. The marine mammals studied were fin whale, minke whale, pilot whale, white-sided dolphins, harbour porpoise, ringed seal and hooded seal. The study aims at giving a wide scope of the presence of these "new" contaminants in marine mammals in recent time and going back to the 1980s using samples from specimen banks.

Download or read book Mammalogy written by George A. Feldhamer and published by JHU Press. This book was released on 2015-01-15 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the expertise and perspective of five leading mammalogists, the fourth edition of Mammalogy: Adaptation, Diversity, Ecology significantly updates taxonomy, includes a new chapter on mammalian molecular phylogenetics, and highlights several recently described species. There are close to 5,500 species in the class Mammalia, including the blue whale—the largest animal that has ever lived—and the pygmy shrew, which weighs little more than a penny. The functional diversity of mammals has allowed them to play critical roles in every ecosystem, whether marine, freshwater, alpine, tundra, forest, or desert. Many mammal species are critically endangered and present complex conservation and management challenges. This book touches on those challenges, which are often precipitated by overharvesting and habitat loss, as well as emerging threats, such as the impact of wind turbines and white nose syndrome on bats and chronic wasting disease on deer. Among the updates and additions to the fourth edition of Mammalogy are numerous new photos, figures, and cladograms, over 4,200 references, as well as • A completely new chapter on mammalian phylogeny and genomics • Current taxonomy—including major changes to orders, suborders, and superfamilies of bats and rodents • An explanation of the recent inclusion of whales with terrestrial even-toed ungulates • Updates on mammalian structural, functional adaptations, and fossil history • recent advances in our understanding of phylogeny, biogeography, social behavior, and ecology • A discussion of two new orders and thirteen newly recognized extant families • Reflections on the implications of climate change for mammals • Thorough examinations of several recently described species, including Durrell's vontsira (Salanoia durrelli) and the Laotian rock rat (Laonastes aenigmamus) • An explanation of mammalian biomechanics, such as that seen in lunge feeding of baleen whales • Breakout boxes on unique aspects of mammals, including the syntax of bat songs, singing mice, and why there are no green mammals (unless we count algae-covered sloths) Maintaining the accessible, readable style for which Feldhamer and his coauthors are well known, this new edition of Mammalogy is the authoritative textbook on this amazingly diverse class of vertebrates.

Download or read book Arctic Climate Impact Assessment Scientific Report written by Arctic Climate Impact Assessment and published by Cambridge University Press. This book was released on 2005-11-07 with total page 1053 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.

Book excerpt: The National Marine Conservation Areas System Plan is an important step in the process of creating a finite network of national marine conservation areas. The plan sets out an approach for the system's design in which Canada's three bordering oceans and the Great Lakes have been divided into 29 distinct marine regions, with a long-term goal of having a national marine conservation area within each region. The plan also attempts to portray each marine region with descriptions of its wildlife, marine and coastal environments, and current status of conservation areas in the region. The appendix includes a glossary and a list of marine-associated species assigned a status by the Committee on the Status of Endangered Wildlife in Canada.
