Available in PDF, EPUB and Kindle. Book excerpt: Once thought of as a pristine environment, it is now all too apparent that the Arctic is a sink for pollutants transported northwards over long distances in the atmosphere and oceans, and is also likely to be subject to major climate change as a result of global warming. Many ecologists are currently seeking to further our understanding of how arctic ecosystems function, and to detect and predict anthropogenic changes which may occur within them. This book, resulting from a British Ecological Society Special Symposium, addresses these issues.
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 Field Techniques for Sea Ice Research written by Hajo Eicken and published by University of Alaska Press. This book was released on 2010-03-15 with total page 590 pages. 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 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 The Oxford Handbook of the Prehistoric Arctic written by T. Max Friesen and published by Oxford University Press. This book was released on 2016-08-05 with total page 1001 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Arctic was one of the last regions on Earth to be settled by humans, due to its extreme climate, limited range of resources, and remoteness from populated areas. Despite these factors, it holds a complex and lengthy history relating to Inuit, Iñupiat, Inuvialuit, Yup'ik and Aleut peoples and their ancestors. The artifacts, dwellings, and food remains of these ancient peoples are remarkably well-preserved due to cold temperatures and permafrost, allowing archaeologists to reconstruct their lifeways with great accuracy. Furthermore, the combination of modern Elders' traditional knowledge with the region's high resolution ethnographic record allows past peoples' lives to be reconstructed to a level simply not possible elsewhere. Combined, these factors yield an archaeological record of global significance--the Arctic provides ideal case studies relating to issues as diverse as the impacts of climate change on human societies, the complex process of interaction between indigenous peoples and Europeans, and the dynamic relationships between environment, economy, social organization, and ideology in hunter-gatherer societies. In the The Oxford Handbook of the Prehistoric Arctic, each arctic cultural tradition is described in detail, with up-to-date coverage of recent interpretations of all aspects of their lifeways. Additional chapters cover broad themes applicable to the full range of arctic cultures, such as trade, stone tool technology, ancient DNA research, and the relationship between archaeology and modern arctic communities. The resulting volume, written by the region's leading researchers, contains by far the most comprehensive coverage of arctic archaeology ever assembled.

Download or read book The Behaviour of Pinnipeds written by D. Renouf and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: We teach our students of behavioural science that one first defines a research problem, and then the most appropriate animal is selected to investigate hypotheses. The reverse order of events is improper: a particular class of animals should not be studied for its own sake. In the case of the Pinnipeds (seals, sea lions, fur seals and walruses) the organism and the problem are essentially the same. The research questions presented in this volume in one way or another relate to survival in two worlds, the ocean for foraging, and the terrain at its edge or frozen above it for breeding. The evolution of Pinniped behaviour and the mechanisms which underlie it are a consequence of having to cope with two seemingly incompatible sets of environmental constraints. The physiological adaptations for concomitant functioning in two media with very different physical characteristics have produced correlated behav ioural modifications. The energetic demands of reproduction and foraging are idiosyncratic because each activity occurs on opposite sides of the air/water interface. As a result, the mating system must reconcile aquatic design for such functions as locomotion and thermoregulation, with the terrestrial requirements for successful pupping. Similarly, the ecology of this dual habitat prescribes the rules governing the behaviour of the neonate and its interactions with its mother.

Download or read book Settlement Subsistence and Change Among the Labrador Inuit written by David C. Natcher and published by Univ. of Manitoba Press. This book was released on 2012-05-15 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: On January 22, 2005, Inuit from communities throughout northern and central Labrador gathered in a school gymnasium to witness the signing of the Labrador Inuit Land Claim Agreement and to celebrate the long-awaited creation of their own regional self-government of Nunatsiavut. This historic agreement defined the Labrador Inuit settlement area, beneficiary enrollment criteria, and Inuit governance and ownership rights. Settlement, Subsistence, and Change Among the Labrador Inuit explores how these boundaries—around land, around people, and around the right to self-govern—reflect the complex history of the region, of Labrador Inuit identity, and the role of migration and settlement patterns in regional politics. Comprised of twelve essays, the book examines the way of life and cultural survival of this unique indigenous population, including: household structure, social economy of wildfood production, forced relocations and land claims, subsistence and settlement patterns, and contemporary issues around climate change, urban planning, and self-government.

Download or read book Asdell s Patterns of Mammalian Reproduction written by Virginia Douglass Hayssen and published by Cornell University Press. This book was released on 1993 with total page 1036 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the appearance of the second edition of Sydney A. Asdell's widely used Patterns of Mammalian Reproduction in 1964, the field of reproductive physiology has expanded dramatically. Accordingly, this revision adopts a different structure from previous editions, substituting empirical delineations for physiological interpretations. With the emphases now on a presentation of the published facts of mammalian reproduction, it provides a thorough compilation of what is known about the basic reproductive biology of each of the 4300 mammalian species.To gather information, the authors examined more than 20,000 publications, dating up to 1992. They used primary sources as much as possible, supplementing them with English translations of Russian, Finnish, Chinese, and Japanese journals. The data are presented in taxonomic order. Each familial account summarizes the pattern of reproduction for the family and provides lists of citations arranged by topic of the literature on the endocrinology, reproductive anatomy, and reproductive physiology of the family. Following each account is a tabular listing of species-specific data for neonatal mass and size, weaning mass and size, litter size, age at sexual maturity, estrous cycle length, gestation length, lactation length, number of litters per year, and seasonality of reproduction. For each of these reproductive variables, the range of data gleaned from the literature is given, together with the source of each value listed.Virginia Hayssen is Assistant Professor of Biology at Smith College. Ari Van Tienhoven is Professor of Animal Physiology, Emeritus, at Cornell University. Ans Van Tienhoven assisted in the compilation of data for the book.
