Available in PDF, EPUB and Kindle. Book excerpt: For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.
Download or read book Feeding written by Kurt Schwenk and published by Elsevier. This book was released on 2000-08-03 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the first four-legged vertebrates, called tetrapods, crept up along the shores of ancient primordial seas, feeding was among the most paramount of their concerns. Looking back into the mists of evolutionary time, fish-like ancestors can be seen transformed by natural selection and other evolutionary pressures into animals with feeding habitats as varied as an anteater and a whale. From frog to pheasant and salamander to snake, every lineage of tetrapods has evolved unique feeding anatomy and behavior.Similarities in widely divergent tetrapods vividly illustrate their shared common ancestry. At the same time, numerous differences between and among tetrapods document the power and majesty that comprises organismal evolutionary history.Feeding is a detailed survey of the varied ways that land vertebrates acquire food. The functional anatomy and the control of complex and dynamic structural components are recurrent themes of this volume. Luminaries in the discipline of feeding biology have joined forces to create a book certain to stimulate future studies of animal anatomy and behavior.
Download or read book Using Detection Dogs to Monitor Aquatic Ecosystem Health and Protect Aquatic Resources written by Ngaio L. Richards and published by Springer. This book was released on 2018-08-10 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the varied range of emerging applications using specially trained detection dogs to monitor and protect aquatic ecosystems, animals, plants and related resources. Featuring contributions from those at the forefront of converging disciplines ranging from canine training, ecological and biological monitoring, water resource management, law enforcement, and eco-toxicology, it addresses everyone already immersed in these or related fields, and anyone seeking to gain a broader understanding of them. Chapters cover several common themes including monitoring presence/absence through biological and ecological surveys; maintaining and evaluating water quality; law enforcement and anti-poaching initiatives; public education, awareness and compliance; standards and best practices; optimal uses of dogs in relation to and in conjunction with other available tools and pragmatic considerations for selecting and working with dogs and handlers. The aim of the book is to stimulate new ideas, promote the sharing and dissemination of information and findings - and, ideally, to catalyze new and innovative partnerships, to strengthen the preservation and conservation of our aquatic heritage.

Download or read book Sex Size and Gender Roles written by Daphne J. Fairbairn and published by OUP Oxford. This book was released on 2007-07-05 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do males and females frequently differ so markedly in body size and morphology?lSex, Size, and Gender Roles is the first book to investigate the genetic, developmental, and physiological basis of sexual size dimorphism found within and among the major taxonomic groups of animals. Carefully edited by a team of world-renowned specialists in the field to ensure a coherence of style and approach between chapters, it presents a compendium of studies into the evolution, adaptive significance, and developmental basis of gender differences in body size and morphology. Adaptive hypotheses allude to gender-specific reproductive roles and associated differences in trophic ecologies, life history strategies, and sexual selection. This "adaptationist" approach is balanced by more mechanistic studies of the genetic, developmental and physiological basis of sexual size dimorphism to provide a comprehensive and authoritative overview of the subject. Throughout the volume the emphasis is on sexual dimorphism in overall size; however, the scope of enquiry encompasses gender differences in body shape, the size and structure of secondary sexual characteristics, patterns of growth (ontogeny), and patterns of gene regulation. This advanced, research level text is suitable for graduate level students and researchers in the fields of evolutionary biology, behavioural ecology, physiology, developmental biology, and genetics. It will also be of relevance and use to non-biologists from fields such as anthropology and gender studies.

This book was released on 2006-01-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the little known species in the danger of extinction, gymophionan amphibians, are also known as caecilians or apoda. Gymnophiona contains 154 species belonging to 34 genera and 6 families. For many years, studies on the Gymnophiona were disparate and still only a few species have been deeply studied. Fortunately, in recent years, some new works have been published on their systematics, using both the classical methods as well as immunology and molecular biology. New data have also been obtained on the biology, life history, reproductive biology, endocrinology and embryonic development of several species. These fascinating aspects along with other important ones on gymnophionan studies are ably reviewed in this book.
