This book was released on 2015-07-20 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the history of life; events that have captured the imagination of scientists and the general public alike. At first glance, these major evolutionary events seem utterly impossible. The before and after look so fundamentally different that the great transformations of the history of life not only seem impossible, but unknowable. The 500 million year history of vertebrates is filled with change and, as a consequence, every living species contains within its structure, DNA, and fossil record, a narrative of them. A battery of new techniques and approaches, from diverse fields of inquiry, are now being marshaled to explore classic questions of evolution. These approaches span multiple levels of biological organization, from DNA sequences, to organs, to the physiology and ecology of whole organisms. Analysis of developmental systems reveals deep homologies of the mechanisms that pattern organs as different as bird wings and fish fins. Whales with legs are one of a number of creatures that tell us of the great transformations in the history of life. Expeditions have discovered worms with a kind of head, fishes with elbows, wrists, and necks; feathered dinosaurs, and human precursors to name only a few. Indeed, in the last 20 years, paleontologists have discovered more creatures informative of evolutionary transitions than in the previous millennium. "The Great Transformations "captures the excitement of these new discoveries by bringing diverse teams of renowned scientists together to attack particular transformations, and to do so in a contents organized by body part--head, neck, fins, limbs, and then the entire bauplan. It is a work that will transform evolutionary biology and paleontology."

Download or read book Carnivore Behavior Ecology and Evolution written by John L. Gittleman and published by Cornell University Press. This book was released on 2019-05-15 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mammalian order Carnivora is characterized by an incredible range of morphological, ecological, and behavioral variation. Carnivores can be as small as the 100-gram least weasel or as large as the 800-kilogram polar bear. Their reproductive rate can vary from one offspring every five years, as with some black bears, to three litters a year, as with the dwarf mongoose. Group sizes can be traced along a wide continuum, from the solitary ermine to the monogamous golden jackal to the large extended packs of as many as 80 spotted hyenas. Until recently the general habits of most wild carnivore species were inadequately understood. In the last decade, however, improved technologies, including the use of radiotelemetry and night-vision scopes, have led to many important discoveries. This book is at once a critical summary and an evaluation of current research on carnivores. A worthy successor to R.F. Ewer's monumental volume, The Carnivores (Cornell University Press), it is the work of 30 leading carnivore biologists, who here assemble comparative data on the basic anatomical, behavioral, ecological, physiological, reproductive, and evolutionary characteristics of this group. After a general introduction to the Carnivora, the volume is divided in three parts, each of which begins with a brief introduction outlining its main themes. Part I, Behavior, covers acoustic and olfactory communication, behavioral development, behavioral ecology of canids and hyaenids, modes of solitary living, and group living. In Part II, Ecology, topics include feeding ecology of the giant panda and Asiatic black bear, adatpations for aquatic living, ecological constraints on predation in felids, consequences of small size in mustelids, rate of basal metabolism and food habits, and reproductive output. Part III, Evolution, deals with the morphological approaches to phylogeny, and the fossil record. An appendix presents a complete classification of the Carnivora, including topics of continuing controversy. Highlighting recent developments in the study of the Carnivora and areas for further research, this broad synthesis will be of great value of students and researchers in animal behavior, behavioral ecology, wildlife ecology, mammalogy, paleontology, systematics, and evolution theory. It will also encourage realistic conservation programs to manage rapidly diminishing populations and will elucidate particular features of the carnivores for nonspecialist readers.

This book was released on 1989-01-01 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides the first full description and analysis of the postcranial skeleton of the Tertiary canid subfamily Borophagine. Borophagines have been stereotyped as noncursorial, bone-crushing scavengers, but comparisons with Recent digitigrade carnivores reveal a surprising diversity of habit among borophagines. The author relates functional characteristics to various aspects of borophagine paleoecology, including habitat, diet, social organization, and extinction.
