Monitor lizards (genus Varanus) have attracted a great deal of interest--these large and impressive lizards are often the centerpiece of reptile house exhibits. Monitors tend to be fairly wary and difficult to observe--therefore they are not particularly tractable research subjects, but they have nevertheless received an extraordinary amount of attention from devoted students.Varanoid Lizards of the World is a comprehensive account of virtually everything important that is known about monitor lizards, beginning with detailed species accounts and proceeding to various modern comparative analyses. Where possible, people who have had detailed field experience with a particular species have assembled species accounts. In the process of reporting what is known, we also identify what remains to be learned about these lizards. We hope to establish a prototype showing how such a diverse monophyletic group can be exploited both to identify and to understand the actual course of evolution. As such, this effort becomes a protocol for future workers to follow for other groups of closely-related species.

What caused their extinction remains a mystery, and one that makes an intriguing conclusion to this portrait of a true dragon of the past.

Monitor lizards are some of the most exciting captives that reptile enthusiasts can keep. They are always the center of attention at zoos and pet stores, where their dinosaur-like form captivates and entertains adults and children alike. While many species are inappropriate pets for all but the most experienced keepers, several of the smaller species make wonderful captives. Nevertheless, even the smallest species require relatively large cages and inordinate amounts of food, so keepers must consider the acquisition of a monitor lizard carefully. For those that choose to add a monitor lizard to their family, it is imperative to learn about the biology, natural history and habitats of these remarkable lizards. By doing so, you can gain a better understanding of their needs, allowing you to keep your pet happy and healthy for many years. Topics covered in this book: - Anatomy - Biology - Behavior - Taxonomy - Costs - Acquiring - Captive Habitat - Enclosures - Heating - Lighting - Temperature - Maintenance - Feeding - Hydration - Interaction - Health Problems - Breeding - Good pet species ----- and much more

The first, definitive reference on the natural history and ecology of every one of the known 6500+ species of lizards, spanning the entire globe. Our planet is literally crawling with lizards. More than 6500 species are known to science, and new species are being discovered annually. In this monumental work, eminent researcher Gordon Rodda has created the first compilation of the natural histories of all the world's lizards and amphisbaenians, as well as the Tuatara. Although other books have attempted to survey the scope of adaptations present in the world's lizards, only Rodda has been able to quantify and summarize all species or higher taxa. Analyzing the relationships among traits such as morphologic characteristics, reproductive strategies, and food sources, Rodda uncovers novel insights into reptile ecology. Identifying 14 recurring character syndromes across all the world's lizards, he proposes a new lens for categorization. He also touches on • common names • geographic range • length • mass • age • maturation • differences between the sexes • nominal variables, including diel activity cycle and foraging mode • home range • predator avoidance tactics • thermal biology • social spacing • climate envelope • habitat and microhabitat • reproduction • parental care • diet • population density • conservation status • ecological business models Rodda's alphabetical taxon accounts provide an instantly retrievable sketch of every species, genus, and family. Outlining more than 1500 statistically significant associations extracted from a data matrix composed of more than 300 conditions tabulated—to the extent known—for all 6528 species of lizards, Lizards of the World will be the go-to source for the next generation of reptile ecologists, as well as herpetology students and serious herpetoculturists.

The Ecology of Papua provides a comprehensive review of current scientific knowledge on all aspects of the natural history of western (Indonesian) New Guinea. Designed for students of conservation, environmental workers, and academic researchers, it is a richly detailed text, dense with biogeographical data, historical reference, and fresh insight on this complicated and marvelous region. We hope it will serve to raise awareness of Papua on a global as well as local scale, and to catalyze effective conservation of its most precious natural assets. New Guinea is the largest and highest tropical island, and one of the last great wilderness areas remaining on Earth. Papua, the western half of New Guinea, is noteworthy for its equatorial glaciers, its vast forested floodplains, its imposing central mountain range, its Raja Ampat Archipelago, and its several hundred traditional forest-dwelling societies. One of the wildest places left in the world, Papua possesses extraordinary biological and cultural diversity. Today, Papua’s environment is under threat from growing outside pressures to exploit its expansive forests and to develop large plantations of oil palm and biofuels. It is important that Papua’s leadership balance economic development with good resource management, to ensure the long-term well-being of its culturally diverse populace.

Alone on the endless red-sand desert in the Australian outback, tracking Varanus giganteus, the perentie lizard that grows to be more than six feet long. . . for desert rat Eric Pianka, such adventures have led to a satisfying, if unusual, way of life, as well as a distinguished career as a field biologist. In The Lizard Man Speaks, Pianka recounts more than thirty years of adventures in reptile studies, beginning with a boyhood passion for collecting snakes and lizards. He tells of "lizarding" in the North American deserts, the Kalahari Desert of southern Africa, and the Great Victoria Desert in Western Australia. His vivid imagery draws the reader into a world where lions lurk in the darkness beyond a gecko hunter's lights, where being stranded by car trouble miles from the last outpost is a constant danger, and where the wilderness still deserves to be called wild. Along the way, Pianka provides much general information about lizard ecology, the fire succession cycle, and the interaction of humans with the landscape. And he reveals the springs of his own determined spirit and love of solitude, describing a near-fatal boyhood accident and its shaping and character-building effect on the life that followed.

The extraordinary lives of lizards remain largely hidden from human eyes. Lizards feed, mate, lay eggs or give live birth, and carefully manage their temperatures. They struggle to survive in a complex world of predators and competitors. The nearly 700 named Australian species are divided into seven families: the dragons, monitors, skinks, flap-footed lizards and three families of geckos. Using a vast array of artful strategies, lizards have managed to find a home in virtually all terrestrial habitats. Australian Lizards: A Natural Historytakes the reader on a journey through the remarkable life of lizards. It explores the places in which they live and what they eat, shows how they make use of their senses and how they control their temperatures, how they reproduce and how they defend themselves. Lavishly illustrated with more than 400 color photographs, this book reveals behavioral aspects never before published, offering a fascinating glimpse into the unseen lives of these reptiles. It will appeal to a diverse readership, from those with a general interest in natural history to the seasoned herpetologist.

Lizards and snakes (squamate reptiles) are the most diverse vertebrate group in Australia, with approximately 1000 described species, representing about 10% of the global squamate diversity. Squamates are a vital part of the Australian ecosystem, but their conservation has been hindered by a lack of knowledge of their diversity, distribution, biology and key threats. The Action Plan for Australian Lizards and Snakes 2017 provides the first comprehensive assessment of the conservation status of Australian squamates in 25 years. Conservation assessments are provided for 986 species of Australian lizards and snakes (including sea snakes). Over the past 25 years there has been a substantial increase in the number of species and families recognised within Australia. There has also been an increase in the range and magnitude of threatening processes with the potential to impact squamates. This has resulted in an increase in the proportion of the Australian squamate fauna that is considered Threatened. Notably over this period, the first known extinction (post-European settlement) of an Australian reptile species occurred – an indication of the increasingly urgent need for better knowledge and management of this fauna. Six key recommendations are presented to improve the conservation management and plight of Australian squamates. This Action Plan represents an essential resource for research scientists, conservation biologists, conservation managers, environmental consultants, policy makers from Commonwealth and State/Territory governments, and the herpetological community.
