Download or read book Pinnipeds and El Ni o written by Fritz Trillmich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: El Niño is a meteorological and oceanographic phenomenon, which occurs at irregular intervals in the eastern tropical Pacific. Its most obvious characteristic is the warming of surface waters, which causes enormous disturbances of the marine environment. A severe Niño may also affect continental systems worldwide. This book gathers in a comprehensive way the information available on the effects of the exceptionally strong 1982-83 Niño on a group of marine mammals, the pinnipeds. It presents an analysis of the effects of environmental stress on the populations of top predators. Data and interpretations are based on a most unusual collection of long-term studies of pinniped population dynamics, behavior and ecology which spanned the El Niño event. The responses of pinniped populations to the El Niño disturbance of the marine ecosystem also has important implications for the management and conservation of marine mammal populations.

Download or read book Fur Seals and Sea Lions written by Roger Kirkwood and published by CSIRO PUBLISHING. This book was released on 2013-06-12 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fur seals and sea lions are charismatic, large carnivores that engage us with both their skill and playful antics. Although all species in Australian waters were harvested to near extinction 200 years ago, fur seals are recovering and are now common in near-shore waters across southern Australia. Sea lions, however, are endangered. Their populations appear not to have recovered like fur seals and are declining at some locations. Fur seals and sea lions are important top level predators and play an important role in Australia’s temperate marine ecosystems. Key threats they currently face relate to human activities, particularly interactions with fisheries. This book outlines the comparative evolutionary ecology, biology, life-history, behaviour, conservation status, threats, history of human interactions and latest research on the three species of otariids that live in the waters of southern Australia: the Australian fur seal, New Zealand fur seal and Australian sea lion. It also includes brief descriptions of Antarctic and Subantarctic seals that occupy the Antarctic pack-ice and remote Australian territories of Macquarie Island and Heard Island.

Download or read book Behavior and Ecology of the Northern Fur Seal written by Roger L. Gentry and published by Princeton University Press. This book was released on 2014-07-14 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering the behavior and ecology of the northern fur seal, this book is a model long-term study of marine mammals, one that tests theory through both observation of undisturbed behavior and manipulative experiments on individuals. Here Roger Gentry draws on nearly two decades of research on three different islands to show how behavior among these seals changes with population size, sex ratio, and environment, to explain the behavior of the population beginning with individuals, and to generalize the results to other members of the eared seal family. In so doing, he offers one of the most comprehensive studies of its kind on any marine mammal species to date. Gentry shows that the species is driven by very different behavioral traits than have been assumed for it in the past. His book analyzes behavior on scales of hours to lifetimes, investigates the mating system, considers processes that underlie the mating system (site fidelity, behavioral estrus, and the development of territoriality), and addresses specific aspects of maternal strategy (female attendance behavior, pup growth, seasonal influences, and the effects of continental shelf width). Gentry contributes to knowledge about marine mammals by providing a very specific basis for interspecies comparisons, and he suggests a link between population trend and environmental regime shifts. He also guides the debate over seal mating systems from an interpretive to an empirical or experimental basis. Originally published in 1997.

Download or read book Below the Convergence written by Alan Gurney and published by W. W. Norton & Company. This book was released on 2007-02-27 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This wonderfully written book tells of the first Herculean expeditions to Antarctica, from astronomer Edmond Halley's 1699 voyage in the Paramore to the sealer John Balleny's 1839 excursion in the Eliza Scott, all in search of land, glory, fur, science, and profit. Life was harsh: crews had poor provisions and inadequate clothing, and scurvy was a constant threat. With unreliable--often homemade--charts, these intrepid explorers sailed in the stormy waters of the Southern Ocean below the Convergence, that sea frontier marking the boundary between the freezing Antarctic waters and the warmer sub-Antarctic seas. These men were the first to discover and exploit a new continent, which was not the verdant southern island they had imagined but an inhospitable expanse of rock and ice, ringed by pack ice and icebergs: Antarctica.
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.
Download or read book Biology and Ecology of Antarctic Krill written by Volker Siegel and published by Springer. This book was released on 2016-08-03 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.
Download or read book Fraser s Penguins written by Fen Montaigne and published by Henry Holt and Company. This book was released on 2010-11-09 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dramatic chronicle of Antarctica's penguins that bears witness to climate changes that foreshadow our own future The towering mountains and iceberg-filled seas of the western Antarctic Peninsula have for three decades formed the backdrop of scientist Bill Fraser's study of Adélie penguins. In that time, this breathtaking region has warmed faster than any place on earth, with profound consequences for the Adélies, the classic tuxedoed penguin that is dependent on sea ice to survive. During the Antarctic spring and summer of 2005-2006, author Fen Montaigne spent five months working on Fraser's field team, and he returned with a moving tale that chronicles the beauty of the wildest place on earth, the lives of the beloved Adélies, the saga of the discovery of the Antarctic Peninsula, and the story—told through Fraser's work—of how rising temperatures are swiftly changing this part of the world. Captivated by the tale of these polar penguins and a memorable field season in Antarctica, readers will come to understand that the fundamental changes Fraser has witnessed in the Antarctic will soon affect our lives.
