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

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.

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.

Archosaurs, an important reptile group that includes today's crocodiles and birds, arose during the Triassic in the aftermath of the greatest mass extinction of all time. In the last 20 years, our understanding of the early evolution of the group has improved substantially with the discovery of new fossils and species of early archosaurs and their closest relatives, a better understanding of the relationships of these animals, and new insights into their palaeobiology. In order to synthesize these new data, researchers of early archosaurs from around the world met at the first symposium of early archosaur evolution at the IV Congreso Latinoamericano de Paleontología de Vertebrados (September 2011) in San Juan, Argentina. This symposium facilitated collaboration and strove to paint a better understanding of these extraordinary animals. The resultant body of work is a state-of-the-art examination of early archosaur groups and their close relatives including historical, anatomical, biogeographical, evolutionary and palaeobiological data. This contribution furthers our knowledge of the anatomy, relationships, and palaeobiology of species-level taxa as well as more global patterns of archosaur evolution during the Triassic -- P. 4 of cover.

The ultimate guide to understanding the biology and behavior of the amazing and underappreciated American alligator. Few scenes put the senses on edge more than a submerged alligator, only eyes and snout showing, when peering across a southern lake on a misty morning. An iconic American predator, these reptiles grow to thirteen feet or more and can live as long as humans. Alligators are complex creatures, capable of terrific attacks and yet tending to their young in the same gentle way a mother duck looks after her brood. Once extremely numerous, alligators came close to extinction in the twentieth century, but thanks to conservation efforts have since made a comeback, reclaiming their rightful place as the monarchs of the southern wetlands. In this fascinating account, richly illustrated with more than 150 photographs from award-winning wildlife photographer Wayne Lynch, expert zoologist Kent A. Vliet introduces readers to the biology, ecology, and natural history of the American alligator. Sharing nuanced depictions of their hidden lives that will forever change the way you think of these giant reptiles, the book • combines captivating storytelling with the most current scientific facts • chronicles the life cycle of the alligator • explains why the alligator's precise anatomy and physiology make it so successful • covers a wide range of topics, from courtship and reproduction to communication, basking, nest-building, and hunting • reveals the alligator's sophisticated social life in detail • evaluates the alligator's environmental role as a keystone species • examines the complicated relationship between alligators and people

Illustrated throughout and featuring the most up-to-date biological information available, this volume is a complete overview of the Chinese alligator, a conservation and cultural icon.

Evolution of Nervous Systems, Second Edition, Four Volume Set is a unique, major reference which offers the gold standard for those interested both in evolution and nervous systems. All biology only makes sense when seen in the light of evolution, and this is especially true for the nervous system. All animals have nervous systems that mediate their behaviors, many of them species specific, yet these nervous systems all evolved from the simple nervous system of a common ancestor. To understand these nervous systems, we need to know how they vary and how this variation emerged in evolution. In the first edition of this important reference work, over 100 distinguished neuroscientists assembled the current state-of-the-art knowledge on how nervous systems have evolved throughout the animal kingdom. This second edition remains rich in detail and broad in scope, outlining the changes in brain and nervous system organization that occurred from the first invertebrates and vertebrates, to present day fishes, reptiles, birds, mammals, and especially primates, including humans. The book also includes wholly new content, fully updating the chapters in the previous edition and offering brand new content on current developments in the field. Each of the volumes has been carefully restructured to offer expanded coverage of non-mammalian taxa, mammals, primates, and the human nervous system. The basic principles of brain evolution are discussed, as are mechanisms of change. The reader can select from chapters on highly specific topics or those that provide an overview of current thinking and approaches, making this an indispensable work for students and researchers alike. Presents a broad range of topics, ranging from genetic control of development in invertebrates, to human cognition, offering a one-stop resource for the evolution of nervous systems throughout the animal kingdom Incorporates the expertise of over 100 outstanding investigators who provide their conclusions in the context of the latest experimental results Presents areas of disagreement and consensus views that provide a holistic view of the subjects under discussion

The Biology and Identification of the Coccidia (Apicomplexa) of Marsupials of the World contains the most up-to-date information on the former order marsupial that is now partitioned by mammalogists into seven separate orders that contain 20 families, 86 genera, and 318 species that live on land or in trees in Oceania and the Americas. Marsupials, like other vertebrate animals have many different kinds of parasites (e.g. viruses, protozoa, worms, arthropods, etc.), but there is no definitive text that covers any one of these groups found in all marsupials. Coccidiosis is a serious global problem in most domesticated animals, and under increasing circumstances of loss of habitat and crowding, may also affect some wild animal populations, thus, there is a real need for their identification and control. Offers line drawings and photomicrograph of each parasite from each hosts species, including methods of identification and treatment Presents a complete historical rendition of all known publications on coccidia (and their closest relatives) from all marsupials species on Earth, and evaluates the scientific and scholarly merit of each Provides a complete species analysis of the known biology of every coccidian described from marsupials Reviews the most current taxonomy of marsupials and their phylogenetic relationships needed to help assess host-specificity and evaluate what little cross-transmission work is available
