Book Synopsis Variation in Growth and Seasonal Condition of Ringed Seal, Phoca Hispida, from the Canadian Arctic by : Michael A. Goodyear
Download or read book Variation in Growth and Seasonal Condition of Ringed Seal, Phoca Hispida, from the Canadian Arctic written by Michael A. Goodyear and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ringed seal (Phoca hispida) morphometric data from three locations in the eastern Canadian Arctic were compared to examine geographic variation in aspects of growth, life-history, and condition. Seals from Eureka (80$\sp\circ$ N) reached an asymptotic length of 150.9 cm, 14.0 cm greater than individuals from Arctic Bay (73$\sp\circ$ N) and 22.7 cm greater than those from Pangnirtung (66$\sp\circ$ N). Seals may reach sexual maturity sooner in Arctic Bay than Eureka or Pangnirtung. Statistically significant sexual dimorphism was evident in Pangnirtung were males were 6.7% longer than females. Condition, expressed as blubber content (% of total mass) was estimated using three published indices of condition: blubber thickness, axillary girth/length $\bullet$ 100, and the 'LMD' index. These indices did not adequately describe changes in condition for this data and did not provide a meaningful measure of the absolute amount of fat present. A new method of estimating absolute sculp (skin and blubber) mass from sculp volume calculated by a prolate spheroid model was developed. Regressions of mass in relation to length for various seasons demonstrated that spring and summer mass loss averaged 14 kg for an adult seal with an asymptotic length of 128 cm. Prior to sexual maturity, juveniles lost proportionally less mass than adults. Observed differences in growth and condition may reflect variation in life-history strategies related to primary productivity and predation pressure by polar bear (Ursus maritimus) and Inuit.
Book Synopsis Ethology and Behavioral Ecology of Phocids by : Daniel P. Costa
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.

Book Synopsis Ecology of Arctic Environments by : Sarah J. Woodin
Download or read book Ecology of Arctic Environments written by Sarah J. Woodin and published by Cambridge University Press. This book was released on 1997-08 with total page 304 pages. 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.
Book Synopsis A Little Less Arctic by : Steven H. Ferguson
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.
Book Synopsis The Behaviour of Pinnipeds by : D. Renouf
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.
Book Synopsis Field Techniques for Sea-Ice Research by : Hajo Eicken
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.
