Download or read book The Beginning of the Age of Mammals written by Kenneth D. Rose and published by JHU Press. This book was released on 2006-10-31 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of G. G. Simpson's classic work, Kenneth D. Rose's The Beginning of the Age of Mammals analyzes the events that occurred directly before and after the mysterious K-T boundary which so quickly thrust mammals from obscurity to planetary dominance. Rose surveys the evolution of mammals, beginning with their origin from cynodont therapsids in the Mesozoic, contemporary with dinosaurs, through the early Cenozoic, with emphasis on the Paleocene and Eocene adaptive radiations of therian mammals. Focusing on the fossil record, he presents the anatomical evidence used to interpret behavior and phylogenetic relationships. The life's work of one of the most knowledgeable researchers in the field, this richly illustrated, magisterial book combines sound scientific principles and meticulous research and belongs on the shelf of every paleontologist and mammalogist.

Download or read book The Emergence of Whales written by J.G.M. Thewissen and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Download or read book The Great Sperm Whale written by Richard Ellis and published by University Press of Kansas. This book was released on 2011-04-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, Richard Ellis has produced a remarkable body of work that has been called "magnificent" (Washington Post Book World), "masterful" (Scientific American), "magical" (Men's Journal), and a "dazzling tour de force" (Christian Science Monitor). Ellis's new book-a fascinating tour through the world of the sperm whale-will surely inspire more such praise for the author heralded by Publisher Weekly as "America's foremost writer on marine research." Written with Ellis's deep knowledge and trademark passion, verve, and wit-and illustrated with a wide array of images including his own signature artwork-his study covers the full spectrum of the sperm whale's existence from its prehistoric past to its current endangered existence. Ellis, as no one else can, illuminates the iconic impact of Physeter macrocephalus ("big-headed blower") on our history, environment, and culture, with a substantial nod to Herman Melville and Moby-Dick, the great novel that put the sperm whale (and whaling) on the literary map. Ranging far and wide, Ellis covers the sperm whale's evolution, ecology, biology, anatomy, behavior, social organization, intelligence, communications, migrations, diet, and breeding. He also devotes considerable space to the whale's hunting prowess, including its clashes with the giant squid, and to the history of the whaling industry that decimated its numbers during the last two centuries. He even includes a story about a beached juvenile he helped rescue, an event that provided scientists with one of their first opportunities to observe a sperm whale in the water and up close. Offering a rich tapestry for anyone with an interest in the marvels of ocean life, Ellis's book provides an indispensable guide to the life and times of one of the planet's most intelligent, elusive, and endangered species.

Download or read book Invasion Biology and Ecological Theory written by Herbert H. T. Prins and published by Cambridge University Press. This book was released on 2014-01-23 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many conservationists argue that invasive species form one of the most important threats to ecosystems the world over, often spreading quickly through their new environments and jeopardising the conservation of native species. As such, it is important that reliable predictions can be made regarding the effects of new species on particular habitats. This book provides a critical appraisal of ecosystem theory using case studies of biological invasions in Australasia. Each chapter is built around a set of eleven central hypotheses from community ecology, which were mainly developed in North American or European contexts. The authors examine the hypotheses in the light of evidence from their particular species, testing their power in explaining the success or failure of invasion and accepting or rejecting each hypothesis as appropriate. The conclusions have far-reaching consequences for the utility of community ecology, suggesting a rejection of its predictive powers and a positive reappraisal of natural history.

Download or read book The Walking Whales written by J. G. M. Hans Thewissen and published by Univ of California Press. This book was released on 2019-04-29 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A ... first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society"--Dust jacket flap.

Download or read book Aquagenesis written by Richard Ellis and published by Viking Adult. This book was released on 2001 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Ellis's detailed drawings bring animals to life that have not been seen for 400 million years, some that rival science fiction monsters for sheer weirdness. Early crocodiles and turtles were three times larger than they are today: and there was once a manatee that was 30 feet long and had no bones below the elbow. There were the trilobites, jointed animals with complex eyes that dominated the seas for 200 million years and then completely disappeared: sharks with teeth on their backs: and others, 50 feet long, with teeth the size of your hand." "Fifty million years ago, some land-dwelling mammals reentered the water and began the process of modification that turned them into whales. It was the most astonishing transformation in mammalian history. In Aquagenesis, you will track these changes and meet the paleontologists who have found the links between the terrestrial mammals and the first semiaquatic whales - creatures that probably looked like hyenas, huge shrews, or fat otters. Today the only animal on earth that regularly walk in an upright, two-legged stance are penguins and people. It is possible that our size, shape, stride, intelligence, and hair (or lack thereof) can also be explained by the provocative theory of the aquatic ape."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
