Crocodiles


Book Description

This book is a comprehensive reference work on the biology, management and health of crocodiles, alligators and gharials. It is applicable to both farmed and captive animals.The introductory chapter describes crocodilian anatomy, physiology, biochemistry, and behaviour. One chapter is devoted to important aspects of crocodile farming, namely nutrition; incubation of eggs; rearing; breeding; slaughter; and welfare. Subsequent chapters cover transmissible, nontransmissible and organ diseases, and diseases of eggs and hatchlings.




Reproductive Biology of the Crocodylia


Book Description

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

Crocodile


Book Description

An ancient animal whose ancestors have roamed the earth since the time of the dinosaurs, the crocodile has survived continental drift, ice ages and the loss of once-prolific species. Today, the Australian saltie, the Chinese alligator, the Indian gharial and the black caiman are just some of the twenty-three species of crocodilian descendants found across the world. Human interaction with these dangerous yet intriguing animals has been reflected in myths and legends dating back to earliest recorded history. Feared or revered, crocodilians have always fascinated. Sadly, many breeds of this seemingly indestructible species are now facing extinction because of human activity, intrusion into their habitats and retaliation for the threat they pose to humans. This is the fascinating and extraordinary story of the crocodile, one of evolution's greatest survivors. Lynne Kelly has been teaching science, mathematics and gifted education for over 30 years. She holds a degree in engineering, education and computing, and is the author of numerous books and online courses for education, a novel and a popular science title, The Skeptic's Guide to the Paranormal.




Tears for Crocodilia


Book Description

Seventy million years ago in what would become North America, a monstrous thirty-five-foot-long Cretaceous crocodile lurked on a marshy riverbank. Springing suddenly, its huge jaws trapped and crushed a juvenile hadrosaur. Today, the remains of that ancient crocodile are being painstakingly reconstructed in Colorado, where naturalist Zach Fitzner continues his life-long fascination with this amazing animal family. In Tears for Crocodilia: Evolution, Ecology, and the Disappearance of One of the World's Most Ancient Animals, Fitzner tracks the evolution of crocodilians from prehistoric predators to modern endangered wildlife, using his own experiences with these reptiles as a lens to understanding wildlife conservation and our relationship with the natural world. Traveling the world to interact with crocodiles, from observing alligators in a wildlife refuge in Texas and paddling a canoe in the Everglades searching for crocodiles to trekking the jungles in Nepal to find endangered gharials, the author expresses a wonder in exploring these diverse ecosystems, making a connection between crocodilians and the lands they live in. As the story follows crocodilians, it also illuminates their often complicated relationship with humans, from crocodile cults in ancient Egypt to American alligators living on golf courses. Fitzner also closely examines the dark side of this relationship, including habitat destruction and poaching as well as the mechanistic view of traditional conservation that turns these magnificent animals into agricultural products. Tears for Crocodilia delves deeply into issues of wildlife conservation, ethics, and how we can coexist with other creatures. It is also a tribute to a magnificent group of animals, survivors from the age of dinosaurs.




Alligators


Book Description

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







Anatomy, Phylogeny and Palaeobiology of Early Archosaurs and Their Kin


Book Description

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.
