Available in PDF, EPUB and Kindle. Book excerpt: This report describes results of aerial surveys conducted to determine the distribution and abundance of ringed seals (Phoca hispida) in the central Beaufort Sea off Alaska ... Specific objectives were to: 1) review and refine protocols for monitoring ringed seals by aerial surveys; 2) estimate relative abundance and density of ringed seals on fast ice in the Beaufort Sea during 1996-1999 and compare with data collected during 1985-1987; and 3) correlate observed ringed seal densities on fast ice with environmental parameters."--Page vi.

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 Thermal Imaging Techniques to Survey and Monitor Animals in the Wild written by Kirk J Havens and published by Academic Press. This book was released on 2015-09-22 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal Imaging Techniques to Survey and Monitor Animals in the Wild: A Methodology provides a manual for anyone interested in understanding thermal imaging and its usefulness in solving a wide range of problems regarding the observation of wildlife. In the last decade, the cost of thermal imaging technology has significantly decreased, making the equipment more widely available. This book offers an overview of thermal physics and the thermal imager, along with a methodology to optimize the window of opportunity so that wildlife can be observed and studied in their natural habitat. Users will find the knowledge and tools to formulate a sound survey design, with detailed sections on the theory and performance characteristics of thermal imaging cameras utilizing cooled quantum detectors as the sensitive element and additional information on the uncooled micro bolometric imagers which have been introduced into the camera market in past decades. The methodology presented is logical and simple, yet it presents a detailed understanding of the topic and how it applies to the critically interlinked disciplines of biology, physics, micrometeorology, and animal physiology. Covers the technical aspects of thermal imaging allowing readers to design better experiments Provides a clear description of the properties of thermal imaging Includes approaches to consider before integrating thermal cameras into a field

Download or read book Indigenous Peoples Food Systems written by Harriet V. Kuhnlein and published by Fao. This book was released on 2009 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, globalisation and homogenisation have replaced local food cultures. The 12 case studies presented in this book show the wealth of knowledge in indigenous communities in diverse ecosystems, the richness of their food resources, the inherent strengths of the local traditional food systems, how people think about and use these foods, the influx of industrial and purchased food, and the circumstances of the nutrition transition in indigenous communities. The unique styles of conceptualising food systems and writing about them were preserved. Photographs and tables accompany each chapter.

Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?
Download or read book Ecosystem Barents Sea written by Egil Sakshaug and published by Tapir Academic Press. This book was released on 2009 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the marine ecosystem of the Barents Sea, located north of Norway and Russia as part of the Arctic Ocean. Basic knowledge is presented about components of the ecosystem from virus and bacteria via plankton and fish to seabirds through to marine mammals and their interactions with the physical environment. Ecosystem dynamics are given a prominent role in the book. Mathematical models of the plankton and important fish stocks are employed to help elucidate the interplay between populations and trophic levels. The situation regarding contaminants is reviewed, as is the newly established Norwegian plan for the management of the Barents Sea. The impact of global warming is also discussed. Ecosystem Barents Sea is written for all those with an interest in marine ecology in the arctic seas, including research institutes, governmental ecosystem management units, and natural resources organizations.
