New Zealand Amphibians And Reptiles In Colour

WINNER OF THE BEST FIELD GUIDE AT THE WHITLEY AWARDS 2019 Packed with extraordinary photographs, this ground-breaking book represents the first accessible field guide to the reptiles and amphibians of New Zealand, covering all 123 species. From the ancient tuatara to the world's largest collection of long-lived and live-bearing lizards, every species account includes an accurate distribution map and information on appearance, habitat, similar species and natural history. This definitive guide also features a comprehensive introduction to evolution, conservation, ecosystems and geographic history. This is the ultimate photographic field guide to New Zealand's herpetofauna, and is a gateway into the world of these fascinating tetrapods for amateur and expert herpetologists alike.

An art folio containing over 80 illustrations. The drawings are in black and white, the photographs are in colour. Formatted in Word 2002.

This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency--either accidentally or deliberately--and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by and independent of mankind.

This edited volume is a timely and comprehensive summary of the New Zealand lizard fauna. Nestled in the south-west Pacific, New Zealand is a large archipelago that displays the faunal signatures of both its Gondwanan origins, and more recent oceanic island influences. New Zealand was one of the last countries on Earth to be discovered, and likewise, the full extent of the faunal diversity present within the archipelago is only just starting to be appreciated. This is no better exemplified than in lizards, where just 30 species (20 skinks, 10 geckos) were recognized in the 1950s, but now 104 are formally or informally recognized (61 skinks, 43 geckos). Thus, New Zealand contains one of the most diverse lizard faunas of any cool, temperate region on Earth. This book brings together the world’s leading experts in the field to produce an authoritative overview of the history, taxonomy, biogeography, ecology, life-history, physiology and conservation of New Zealand lizards.

Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Everyone has heard of the tuatara, New Zealand¿s unique `living dinosaur¿; but equally fascinating, if less well known, are the country¿s other reptiles. There are more than 65 species of lizards (including skinks and geckos), frogs and other reptiles and amphibians native to New Zealand, and scientists such as author Tony Jewell are still discovering new species and subspecies today. In this new addition to a popular New Holland series, Tony covers all the known species from Northland to the far south; his text is backed up by outstanding photographs of their many geographic colour variants, so that readers will be equipped to identify almost any specimen encountered in the wild. A groundbreaking handbook and a superb aid for natural history enthusiasts, trampers and educationalists.
