Download or read book Evolutionary Paleobiology of Behavior and Coevolution written by A.J. Boucot and published by Elsevier. This book was released on 2013-10-22 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the culmination of many years of research by a scientist renowned for his work in this field. It contains a compilation of the data dealing with the known stratigraphic ranges of varied behaviors, chiefly animal with a few plant and fungal, and coevolved relations. A significant part of the data consists of ``frozen behavior'', i.e. those in which an organism has been preserved while actually ``doing'' something, as contrasted with the interpretations of behavior of an organism deduced from functional morphology, important as the latter may be. The conclusions drawn from this compilation suggest that both behaviors and coevolved relations appear infrequently, following which there is relative fixity of the relation, i.e., two rates of evolution, very rapid and essentially zero. This conclusion complies well with the author's prior conclusion that community evolution followed the same rate pattern. In fact, communities are regarded here, as in large part, expressions of both behavior and coevolved relations, rather than as random aggregates controlled almost wholly by varied, unrelated physical parameters tracked by organisms, i.e., the concept that communities have no biologic reality, being merely statistical abstractions. The book is illustrated throughout with more than 400 photographs and drawings. It will be of interest to ethologists, evolutionists, parasitologists, paleontologists, and palaeobiologists at research and post-graduate levels.

Download or read book The Skeleton of the Borophaginae Carnivora Canidae written by Kathleen Munthe and published by Univ of California Press. 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.
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 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because carnivores are at the top of the food chain, their status is an important indicator of the health of the world ecosystem. They are intensely interesting to zoologists and uniquely intriguing to the general public. Devoted primarily to terrestrial carnivores, this volume focuses on such themes as carnivore reintroduction programs and the ethics of studying carnivores, drawing examples from a variety of species. The need to evaluate new conceptual ideas and empirical data inspired this volume of Carnivore Behavior, Ecology, and Evolution, a complement to the original book. In the eight years since publication of the first volume, conservation has emerged as a thematic imperative. The study of carnivores has become even more important in raising and resolving crucial biological problems. Differential rates of mortality in the giant panda and other endangered carnivores are now known to influence dispersal and life history patterns basic to these species' survival. Reintroduction efforts of the black-footed ferret and the red wolf are establishing essential guidelines for preservation and management of endangered species. Studies of the African lion and the dwarf mongoose illustrate the power of new genetic techniques of DNA fingerprinting for understanding the evolution of social behavior.
Download or read book Extinctus written by John Reese and published by AuthorHouse. This book was released on 2021-01-14 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Earth, 99% of species are extinct. Extinctus is a world where all vanished species live and die as they did when they inhabited Earth. The battle for survival occurs daily, as it did for millennium, in these hostile and violent epochs. Journey back in time to a world, one filled with fierce predators and harsh climates. Can modern humans survive in these inimical yet magnificent worlds? In Extinctus, the reader travels to three different time periods in the evolution of planet Earth. It takes the reader to the Paleocene Epoch (65-55 million years ago), the Miocene Epoch (23-5 million years ago) and the Pleistocene Epoch (2 million years ago-10,000 years ago). Based off the fossil record, each Epoch in Extinctus is a snapshot in time, a snapshot that reconstructs the emergence of the mammals, the insects, the climate, and the environmental changes over millions of years. How would modern humans fit into these violent worlds? During these expansive periods in geological time, Earth was full of monstrous predatory creatures. For millions of years, the planet stayed an extremely dangerous place for early humans. Extinctus brings to life the evolutionary plight of the mammals as they re-populate the Earth after the disappearance of the dinosaurs. Six humans must survive continual predation by an endless array of creatures as they try to survive in their new surroundings. Extinctus recounts the story of the youngest of three generations of humans to enter Extinctus. Can the youngest member of the family help save the human species? Or will Homo sapiens disappear from the record? With the help of magnificent creatures, with mysterious capabilities, known as Light Extinctos, can the humans thwart the sinister plan of Thylac, the Dark Extincto, who with the help of his delusional army seeks to destroy humanity?

Download or read book Foundations of Paleoecology written by S. Kathleen Lyons and published by University of Chicago Press. This book was released on 2019-12-13 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 99% of all life that has ever existed is extinct. Fortunately, these long dead species have left traces of their lives and interactions with other species in the rock record that paleoecologists use to understand how species and ecosystems have changed over time. This record of past life allows us to study the dynamic nature of the Earth and gives context to current and future ecological challenges. This book brings together forty-four classic papers published between 1924 and 1999 that trace the origins and development of paleoecology. The articles cross taxonomic groups, habitat types, geographic areas, and time and have made substantial contributions to our knowledge of the evolution of life. Encompassing the full breadth of paleoecology, the book is divided into six parts: community and ecosystem dynamics, community reconstruction, diversity dynamics, paleoenvironmental reconstruction, species interaction, and taphonomy. Each paper is also introduced by a contemporary expert who gives context and explains its importance to ongoing paleoecological research. A comprehensive introduction to the field, Foundations of Paleoecology will be an essential reference for new students and established paleoecologists alike.
