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 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.
Download or read book Bears of the North written by Wayne Lynch and published by JHU Press. This book was released on 2021-10-05 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: An unprecedented visual and scientific journey into the secret world of bears. In Bears of the North, renowned wildlife photographer, naturalist, and bestselling author Wayne Lynch offers us a work of scintillating science and stunning beauty. Following polar bears, brown bears, and American and Asiatic black bears through the seasons, this journey is an insider's view of hibernation's mysteries and the birth of cubs in winter; the mating rituals and voracious appetites of spring; hunting, fishing, and encounters with neighbors during summer; and the feeding frenzy and exuberant play of autumn. Dispelling the stereotypes and untruths—but none of the magic—surrounding these magnificent animals, Lynch comments on the latest scientific discoveries related to the biology, behavior, and ecology of bears. He describes how satellite telemetry has revealed the purpose behind the meanderings of bears and the great distances they sometimes cover on land and in water. He also shows how DNA analysis can teach us about the relatedness of bears within a population, even revealing the identity of a particular cub's father. Taking us out into the wilds of the tundra and forests to share his firsthand observations of the marvelous bears of the Northern Hemisphere, Lynch describes their survival strategies and the threats they face from habitat fragmentation and global climate change. Lynch's fascinating narrative is enhanced by over 150 gorgeous, original color photographs that capture bears in their habitats, including appearances of the elusive moon bear, fierce polar bear battles, and rare images of mothers' intimate moments with their cubs. Informed by Lynch's nearly forty years of experience observing and photographing bears in the wild, and aided by sophisticated digital photo technologies, Bears of the North is an unrivaled collection of enthralling and informative portraits of bears in their natural environments.
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 Sea Ice written by David N. Thomas and published by John Wiley & Sons. This book was released on 2017-03-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 20 years the study of the frozen Arctic and Southern Oceans and sub-arctic seas has progressed at a remarkable pace. This third edition of Sea Ice gives insight into the very latest understanding of the how sea ice is formed, how we measure (and model) its extent, the biology that lives within and associated with sea ice and the effect of climate change on its distribution. How sea ice influences the oceanography of underlying waters and the influences that sea ice has on humans living in Arctic regions are also discussed. Featuring twelve new chapters, this edition follows two previous editions (2001 and 2010), and the need for this latest update exhibits just how rapidly the science of sea ice is developing. The 27 chapters are written by a team of more than 50 of the worlds’ leading experts in their fields. These combine to make the book the most comprehensive introduction to the physics, chemistry, biology and geology of sea ice that there is. This third edition of Sea Ice will be a key resource for all policy makers, researchers and students who work with the frozen oceans and seas.

Available in PDF, EPUB and Kindle. Book excerpt: As much as one-tenth of the world’s oceans are covered with sea ice, or frozen ocean water, at some point during the annual cycle. Sea ice thus plays an important, often defining, role in the natural environment and the global climate system. This book is a global look at the changes in sea ice and the tools and techniques used to measure and record those changes. The first comprehensive research done on sea-ice field techniques, this volume will be indispensable for the study of northern sea ice and a must-have for scientists in the field of climate change research.
Download or read book Biology of Marine Mammals written by John E. Reynolds and published by Smithsonian Institution. This book was released on 2013-08-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.
Download or read book Human Impacts on Seals Sea Lions and Sea Otters written by Todd J. Braje and published by Univ of California Press. This book was released on 2011-03-23 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than ten thousand years, Native Americans from Alaska to southern California relied on aquatic animals such as seals, sea lions, and sea otters for food and raw materials. Archaeological research on the interactions between people and these marine mammals has made great advances recently and provides a unique lens for understanding the human and ecological past. Archaeological research is also emerging as a crucial source of information on contemporary environmental issues as we improve our understanding of the ancient abundance, ecology, and natural history of these species. This groundbreaking interdisciplinary volume brings together archaeologists, biologists, and other scientists to consider how archaeology can inform the conservation and management of pinnipeds and other marine mammals along the Pacific Coast.

Download or read book Fingerprints of Climate Change written by G.-R. Walther and published by Springer Science & Business Media. This book was released on 2012-11-09 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years an increasing number of studies have been published reporting observations of adapted behaviour and shifting species ranges of plant and animal species due to recent climate warming. Are these `fingerprints' of climate change? An international conference was organised to bring together scientists from different continents with different expertise but sharing the same issue of climate change impact studies. Ecologists, zoologists, and botanists exchanged and discussed the findings from their individual field of research. The present book is an international collection of biological signs of recent climate warming, neither based only on computer models nor on prediction for the future, but mainly on actually occurring changes in the biosphere such as adapted behaviour or shifts in the ranges of species. `Fingerprints' of Climate Change presents ecological evidence that organisms are responding to recent global warming. The observed changes may foreshadow the types of impacts likely to become more frequent and widespread with continued warming.
