This book deals with reproduction of Amphibians belonging to three extant orders: Caecilians, Salamanders, Frogs and Toads. Separate chapters have been written for males and females; the chapters describe gonad structure and development, gametogenesis, urogenital connections, and reproductive tracts. The authors have provided a synthesis of the lit

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 wo

How to decelerate loss of global biodiversity is one of the greatest challenges of our generation. Reproductive technologies have enormous potential to assist the recovery of species by enhancing reproductive output, facilitating genetic management, and supporting reintroduction of threatened species. Of particular value are cryopreservation technologies coupled with the establishment of global gene banks to conserve, in perpetuity, the remaining extant genetic diversity of threatened amphibians. Reproductive Technologies and Biobanking for the Conservation of Amphibians brings together leading experts in the field to provide a comprehensive overview of current best practices, summarise technological advancements, and present a framework for facilitating the integration of reproductive technologies and biobanking into conservation breeding programs for threatened amphibians. It is an invaluable reference for the next generation of conservation practitioners: captive breeding facilities, researchers, and policy-makers involved with biodiversity conservation.

Generously illustrated, this essential handbook for herpetologists, ecologists, and naturalists features comprehensive keys to eggs, embryos, salamander larvae, and tadpoles; species accounts; a glossary of terms; and an extensive bibliography. The taxonomic accounts include a summarization of the morphology and basic natural history, as well as an introduction to published information for each species. Tadpole mouthparts exhibit major characteristics used in identifications, and the book includes illustrations for a number of species. Color photographs of larvae of many species are also presented. Handbook of Larval Amphibians of the United States and Canada, written by the foremost experts on larval amphibians, is the first guide of its kind and will transform the fieldwork of scientists and fish and wildlife professionals.

South America is one of the few areas of the world that includes vast areas of as yet undisturbed natural habitats. These areas are home to as many as half the world's species of plants and animals. Many of the animals inhabit ing these areas are of direct and immediate economic importance, while others are of unknown potential value. With economic development of these areas, there is a coincident disruption of natural habitats that have a direct impact on the reproductive capabilities of the affected species. Re production is central to the survival of all species and, regardless of the environmental stresses imposed on them, scientific attention must be fo cused on reproductive biology as a way to deal with these pressures. It is vitally important to gather as much research data as possible on the repro ductive biology of the species on this continent in order to provide gov ernmental agencies and scientists with the most accurate information on which to base decisions regarding development. This volume is intended to draw attention to these pressing matters by gathering a wide representation of scientists actively engaged in reproduction research relating to South American vertebrates. It is intended that this volume will serve as a re source for individuals and organizations interested in reproductive biology and species survival. An additional benefit is that economically important species, as well as potentially important ones such as sharks, will be dis cussed.

This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided. A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them

Herpetology has always been one of the most exciting disciplines of zoology. During the past few years the field has continued to grow, yet it has been plagued by scarcity of comprehensive, up-to-date textbooks containing the most important developments. This timely book fills that void. Through skillful synthesis, the author summarizes the diversity in the biology of living amphibians and reptiles and describes the breadth of current herpetological research. Topics covered include the evolution, classification, development, reproduction, population, and environmental issues surrounding the study of amphibians and reptiles. Designed as an advanced undergraduate textbook, Herpetology is a valuable resource for students, practitioners, and interested amateurs alike. Provides an incisive survey and much needed update of the field Emphasizes the biological diversity among amphibians and reptiles Details the most recent research findings, citing ke

This volume contains original contributions from an international group of authors with the highest reputations in their respective areas of phylogenetic and reproductive studies on salamanders and newts. A full panoply of topics is covered, from morphology of gametes and reproductive systems to considerations of behavior and life history, all placed in a phylogenetic context. The chapters not only synthesize past literature but also present new observations and indicate directions for future research. This is an essential text for anyone interested in the biology of urodele amphibians.

The present book is an up-to-date account of the recent advances in the cellular and molecular changes during diverse ovarian functions in amphibians. The ovarian compartments like developing follicles at different stages of growth, atretic follicles, post-ovulatory follicles, corpora atretica, interstitial cells and stroma have been discussed in relation to their changed cellular and molecular attributes vis-à-vis reproductive phases encompassing environmental stress induced variations in the reproductive success and fecundity. Histochemical, ultrastructural, biochemical and molecular biology of oocyte growth, vitellogenesis, steroidogenesis, oocyte maturation, ovulation, post-ovulatory follicular modulation and their endocrine regulation, have been elaborately explained. It provides comprehensive comparative details of basic and applied aspects of amphibian ovary. This book will be of significance to the scientists and students of reproductive biology, biotechnology, conservation biology and environmental toxicology and system biology. This book is of prime importance for conservation of amphibians.
