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.
The goanna's ubiquity and sometimes brazen behaviour has made them a familiar favourite with generations of Australian bushwalkers, campers, and picnickers. This updated editon brings together the fascintating natural history of these ancient animals and other members of the family Varanidae, which includes the world's largest lizard, the Komodo dragon.
What caused their extinction remains a mystery, and one that makes an intriguing conclusion to this portrait of a true dragon of the past.
Lizards of the World is ultimate book on these fascinating creatures, featuring the all the different types of lizard worldwide. As survivors from the time of the dinosaurs, lizards are scaly, cold-blooded, living fossils—relics from a prehistoric world that remain alive and well in ours. Lizards exert a morbid fascination, in many mythologies they are dark creatures, symbolizing death and misfortune. From chameleons and skinks to geckos and iguanas, Lizards of the World brings these creatures firmly into the light, to reveal their extraordinary diversity Found in almost every type of terrain globally, there are almost 6,500 species of lizard, including lizards with frills, horns, or wings, those that drop their tails, and others that squirt blood from their eyes. Here, the lizard family and subfamily profiles, organized phylogenetically, are illustrated with stunning photography. Each profile includes a population distribution map, a table of essential information, and a fascinating commentary revealing notable characteristics, fresh scientific understanding, and the diversity of species. Written by world-renowned herpetologist Mark O’Shea, Lizards of the World is a magnificent showcase of the natural history and beauty of these remarkable reptiles.
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.
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.
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.
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.
The first volume contains species accounts of the venomous lizards and elapid and viperid snakes found north of Mexico's twenty-fifth parallel. Volume two covers the twenty-one species of rattlesnakes found in the United States, Canada, and northern Mexico.
