Reproductive Biology And Phylogeny Of Snakes

Offering coverage of a wide range of topics on snake reproduction and phylogeny, this comprehensive book discusses everything from primordial germ migration in developing embryos to semelparity (death after reproduction) in the aspic viper. Beginning with a review of the history of snake reproductive studies, it presents new findings on development, placentation, spermatogenesis, male and female reproductive anatomy, hormonal control of reproduction, reproductive cycles, sex pheromones, and parental care. An indispensible reference, this book offers comparative chapters on snake phylognetics examining morphological characteristics alongside strictly molecular concerns. It is rife with illustrations and color plates.

Reproductive Biology and Phylogeny of Lizards and Tuatara is a remarkable compendium of chapters written by the world's leading experts from over four continents. The book begins with a chapter recounting historical discoveries in reproductive biology and a review of phylogenetics and up-to-date hypotheses concerning evolutionary relationships among lizards. Following these chapters are detailed reviews with additional new data concerning chemical communication, sexual selection, reproductive cues, female reproductive anatomy, female reproductive cycles, oogenesis, parthenogenesis, male reproductive anatomy, male reproductive cycles, spermatogenesis, reproductive investment, viviparity and placentation, multiple paternity, and parental care. The book culminates in two chapters on tuatara reproduction giving unique insight into evolutionary patterns in reproductive biology in squamates and tuatara. This is an essential resource for anyone studying reproduction in reptiles and/or vertebrates and offers a fascinating read for those interested in reproductive biology.

Snakes of the World: A Catalogue of Living and Extinct Species, published in 2014, was the first catalogue of its kind and covered all living and fossil snakes described between 1758 and 2012.

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.

Latest developments in understanding how, when and where the extraordinary body plan and ecology of snakes evolved from lizard ancestors.

Reproductive Biology of the Crocodylia is based on over 40 years of research on global crocodiles, alligators and caimans. It brings together data and information previously scattered across publications to synthesize knowledge on the history, ecology, physiology and anatomy of crocodilians. The book provides a comprehensive look at the physiology, current taxonomy, ecology and sexual maturity factors of these reptiles. It then delves into the anatomy and cycles of both male and female reproduction systems, including nesting and incubation, temperature-dependent sex determination, and sex ratios across various species populations. Finally, the book focuses on conservation efforts to protect the reproductive cycle, taking factors such as pollution, climate change, and human disruption into consideration. It is an ideal resource for wildlife biologists and herpetologists seeking up-to-date and thorough research data on conservation efforts. It will also be helpful for exotic animal veterinarians, zookeepers, and alligator or crocodile farmers. Focuses on crocodilian reproduction and how it is impacted by seasons, social interactions, pollution, and more Provides a thorough overview by a globally recognized expert on crocodilian reproduction and endocrinology Explores conservation efforts and offers insights for protecting crocodilian reproduction cycles against current factors, including pollution, environmental effects and human interference
