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.

The most thorough, updated guide to frogs and toads in the United States and Canada available. A stunning diversity of frog species can be found from coastal swamps to lofty mountain peaks, and from the Florida Keys to the Arctic Ocean. They live in subtropical lowlands, grassland prairies, deserts, and alpine-tundra habitats. Some species have restricted habitat requirements, whereas others occur contiguously from the arid plains or humid southeastern forests to the high tundra. In this new edition of Frogs of the United States and Canada, C. Kenneth Dodd Jr. tours the reader through the marvelous world of North American frogs. Covering 114 native and introduced species from all US states and Canadian provinces, this comprehensive reference on the biology, behavior, and conservation of the Order Anura includes detailed and updated information on • past and present distribution • life history and demography • reproduction and diet • landscape ecology and evolution • diseases, parasites, and threats from toxic substances • conservation and management Hundreds of occurrence maps, line drawings, and new color photographs of frogs and their habitats enhance the text. The most thorough treatment of the life histories, distribution, and status of North American frogs ever produced, Frogs of the United States and Canada has been the go-to reference for naturalists, scientists, and resource managers in their efforts to understand and conserve frogs, their habitats, and biodiversity for over a decade. Based on a meticulously updated examination of more than 8,000 references current through 2021, this second edition ensures Dodd's master work will remain an unparalleled resource for years to come.

Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.

Everything a student, naturalist, or curious observer wants to know about the biology and diversity of geckos. Q: How do geckos walk across ceilings? A: Millions of hair-like setae on each foot. Q: Where do geckos come from? A: Throughout the world. Usually where it’s warm. Q: How many species of geckos are there? A: Close to 1,500 and counting! Q: What do they eat? A: Insects mostly. Discover the biology, natural history, and diversity of geckos—the acrobatic little lizards made famous by a car insurance ad campaign. Lizard biologist and gecko expert Aaron Bauer answers deceptively simple questions with surprising and little-known facts. Readers can explore color photographs that reveal the natural wonder and beauty of the gecko form and are further informed by images of how geckos live in their natural habitats. Although written for nonexperts, Geckos also provides a carefully selected bibliography and a new list of all known species that will be of interest to herpetologists. Anyone who owns a gecko, has seen them in the wild, or has wondered about them will appreciate this gem of a book.

A comprehensive illustrated guide to the Palmetto State's native species of reptiles From the lowcountry coastal tidelands to the upstate Blue Ridge Mountains and everywhere in between, South Carolina's varied landscapes and habitats are home to a fascinating and mysterious assortment of alligators, turtles, lizards, and snakes. The Reptiles of South Carolina, a comprehensive, illustrated guide to the Palmetto State, includes seventy-five native species of reptiles as well as introduced forms. Jeffrey D. Camper's accessible descriptions and intriguing details are designed to enlighten readers about this misunderstood and often-maligned group of secretive and ecologically important animals. Camper begins with a discussion of the state's mild climate and wide variety of natural habitats, including forests, plains, sandhills, wetlands, and barrier islands. The entry for each species provides a color picture, detailed descriptions of external appearance, variations in size and color, taxonomic keys, comparisons to similar species to aid in identification, and natural history. Camper also assesses the conservation status of each species and offers a detailed range map of where that species is known to occur in the state and another map showing its entire geographic range in the continental United States. The Reptiles of South Carolina includes 92 color and 79 black-and-white illustrations, a checklist by reptile family, a helpful glossary, and a short history of herpetology in the Palmetto State. This authoritative reference will prove invaluable to students, professional herpetologists, conservationists, ecologists, biologists, land managers, and amateur naturalists alike. A foreword is provided by J. Whitfield Gibbons, professor emeritus of ecology at the University of Georgia and former head of the environmental outreach and education program at the Savannah River Ecology Laboratory.

This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
