Book Synopsis Elephant Seals by : Burney J. Le Beouf
Download or read book Elephant Seals written by Burney J. Le Beouf and published by Univ of California Press. This book was released on 2023-11-10 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1994.

Book Synopsis Wildlife 2001: Populations by : D.R. McCullough
Download or read book Wildlife 2001: Populations written by D.R. McCullough and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.

Are there undiscovered big cats and unclassified apes hidden in the world's forests? Do large animals of unknown type lurk in deep lakes or in the oceans? The discoveries, rediscoveries, controversies, and mysteries of modern zoology are collected here in Shadows of Existence, a thoroughly researched and up to date guide to the wonders of nature.
Book Synopsis Pinnipeds and El Niño by : Fritz Trillmich
Download or read book Pinnipeds and El Niño 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.
Book Synopsis The Comeback Kids Book 1, the Northern Elephant Seals by : Penelope Dyan
Download or read book The Comeback Kids Book 1, the Northern Elephant Seals written by Penelope Dyan and published by . This book was released on 2015-06-28 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Northern Elephant Seal, Mirounga angustirostris, the guys with the great big noses and the squabbling harems, are the really big comeback kids; and we mean that, because not only are the elephant seals really big, they have made a really big comeback! Hundreds of thousands of these really fun creatures once inhabited the Pacific Ocean, and then they were wholesale slaughtered in the 1800's for their blubber that could be rendered into oil. Only 50-100 of them were left to roam the vast ocean where they spend most of their time until it is time for them to come ashore to molt or mate. They lumber across land very slowly and they mate and molt on land, so the elephant seals were a very easy target for their human hunters. In 1922 the Mexican government enacted laws to protect them, and a few years later the United States of America did the very same thing. Miraculously these grand animals began to slowly reappear! Today it is estimated there are about 160,000 elephant seals! Males have a life expectancy of 14 years, while a female elephant seal lives to the ripe old age of 20! They are pinnipeds and molt like all pinnipeds do (to get rid of old skin and hair) but they do that all at once, once a year, during the spring and summer; and exactly when they molt depends on the age that they are, and who they are! The females and juveniles molt from April to May, and the young males molt from May to June, while the Adult males molt from July to August. They come to shore to mate and to give birth in December and hang out on the beach for a few months, because the process of birthing and mating and weaning must take its proper course. The female mates approximately 24 days after giving birth. The males are 14 to 16 feet in length and weigh up to two and a half tons each, and the females are a petite 10 to 12 feet in length and weigh a mere 1200 to 2000 pounds. This is the first book in "The Comeback Kids" Book Series. It is meant to inspire and to make you realize anything is possible in this world if we stop doing what is wrong and do what is right, and give mother nature the opportunity to nourish herself. The Photographs by John D. Weigand were taken with reverence at the direction of this author at the seal rookery at Piedras Blancas, at the southern end of Big Sur on the California coast, twelve miles north of Cambria.

Available in PDF, EPUB and Kindle. Book excerpt: Elephant seals have such a fascinating migration story. Unlike migrations of many other animals, male and female elephant seals actually take different migratory routes. They arrive in different parts of the world, eat different food sources, swim different lengths, and spend time in two different temperatures of water, among other things. This fun and informative volume tells the tale of the epic elephant seal journey with accessible, exciting language accompanied by fantastic full-color photographs. A map of both journeys provides opportunity for visual comprehension of the lengths these animals go to every year.
