Reproductive Biology Of The Crocodylia

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

Biology and Evolution of Crocodylians is a comprehensive review of current knowledge about the world's largest and most famous living reptiles. Gordon Grigg's authoritative and accessible text and David Kirshner's stunning interpretive artwork and colour photographs combine expertly in this contemporary celebration of crocodiles, alligators, caimans and gharials. This book showcases the skills and capabilities that allow crocodylians to live how and where they do. It covers the biology and ecology of the extant species, conservation issues, crocodylian–human interaction and the evolutionary history of the group, and includes a vast amount of new information; 25 per cent of 1100 cited publications have appeared since 2007. Richly illustrated with more than 500 colour photographs and black and white illustrations, this book will be a benchmark reference work for crocodylian biologists, herpetologists and vertebrate biologists for years to come.

Aspects of reproduction covered in this volume include classification and phylogeny as revealed by molecular biology; anatomy of the male reproductive tract and organs; development and anatomy of the female reproductive tract; and more.

With the expansion of human settlements and the environmental changes brought on by human activity and pollutants, toxicology and risk assessment of bird and reptile species is becoming increasingly of interest to toxicologists involved in environmental research. This book focuses specifically on environmental risk assessment in non-conventional bird and reptile species. Bird and Reptile Species in Environmental Risk Assessment Strategies will be an ideal companion to toxicologists and ecologists interested in risk assessment in the environments of birds and reptiles, particularly those with an interest in the impact introduced by human activity. The book will also be of interest to those working in conservation biology, biological invasion, biocontrol and habitat management.

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.

The second part of volume 6 discusses sexual selection of ultraviolet and structural signals; melanins and carotenoids as feather colorants and signals; sexual selection and auditory signaling; odors and chemical signaling; sexual dimorphism; sexual selection, signal selection and the handicap principle; courtship and copulation; sexual conflict an

They change color depending on their mood. They possess uniquely adapted hands and feet distinct from other tetrapods. They feature independently movable eyes. This comprehensive volume delves into these fascinating details and thorough research about one of the most charismatic families of reptilesÑChameleonidae. Written for professional herpetologists, scholars, researchers, and students, this book takes readers on a voyage across time to discover everything that is known about chameleon biology: anatomy, physiology, adaptations, ecology, behavior, biogeography, phylogeny, classification, and conservation. A description of the natural history of chameleons is given, along with the fossil record and typical characteristics of each genus. The state of chameleons in the modern world is also depicted, complete with new information on the most serious threats to these remarkable reptiles.
