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.

Download Herping Texas Book in PDF, ePub and Kindle
Coiled beneath discarded trash or rocky slabs, basking along river edges, and tucked into rock cuts beside the highway, reptiles and amphibians constantly surround us. While many people go out of their way to avoid snakes or shudder at the thought of touching a toad, herpers take to the field armed with cameras, hooks, and notebooks hoping to come across a horned lizard, green tree frog, or even a diamondback rattlesnake. In Herping Texas: The Quest for Reptiles and Amphibians, Michael Smith and Clint King, expert naturalists and field herpers, take readers on their adventures across the state as they search for favorite herps and rare finds. Organized by ecoregion, Herping Texas describes some of the state’s most spectacular natural places, from Big Bend to the Big Thicket. Each chapter contains photographs of the various snakes, lizards, toads, and turtles Smith and King have encountered on their trips. Part nature travel writing and part guide to field herping, Herping Texas also includes a section on getting started, where the authors give readers necessary background on best field herping practices. A glossary defines herping lingo and scientific terms for newcomers, and an appendix lists threatened and endangered species at the state and federal level. Herping Texas promotes experiencing natural places and wildlife equipped with solid information and a responsible conservation ethic. Throughout their decades tracking herps, Smith and King have collected humorous anecdotes and fascinating facts about reptiles and amphibians. By sharing those, they hope to dispel some of the stigma and false ideas people have about these misunderstood animals.

Download Reptiles and Amphibians of the Pacific Islands Book in PDF, ePub and Kindle
The Pacific is not only the worldÕs largest body of water; its vast expanse also includes an extraordinary number and diversity of oceanic islands, from Palau and the Marianas east of the Philippines to Cocos Island and the Gal‡pagos west of the Americas. The isolation of these islands and the extreme distances between them long prevented scientists from studying their floras and faunas in a comparative context. But now George R. Zug, one of the world's foremost experts on the diverse reptiles and amphibians of the Pacific Basin, offers the first such systematic overview in more than half a century. Reptiles and Amphibians of the Pacific Islands is a compendium of frogs, lizards, snakes, and turtles living on these lands and in the adjacent waters of the oceanic islands in the tropical Pacific. The means to identify each species is included, along with entries that describe each animal's form, coloration, habitat, distribution, reproductive biology, and natural history. Color plates of more than 75 percent of the species also help to facilitate visual identification. This accessible and informative guide is the most comprehensive field guide available and will appeal to both novice sightseers and professional naturalists.

Download The Status and Distribution of Reptiles and Amphibians of the Mediterranean Basin Book in PDF, ePub and Kindle
The Mediterranean-rim countries hold around 400 million people and 135 million of them live on the coast. A steady migration towards coastal areas, specifically in the south and east of the Mediterranean, is causing pressure on the coastal environment and, more importantly, on its biodiversity. In this second Mediterranean regional assessment, all the reptile and amphibian species existing within the region of study have been evaluated for their global conservation status. This assessment aims to assist in regional planning and to help identify internationally important sites for biodiversity. Like the first in the series, it also hopes to encourage development of a network of regional experts to enable future assessments and the continued updating of the baseline dataset.

Download Invasive Reptiles and Amphibians Book in PDF, ePub and Kindle
In Invasive Reptiles and Amphibians, readers are shown examples of invasive snakes, frogs, and lizards to reveal the pattern of species introduction and habitat takeover. Identifying the adaptations of species like the Cane Toad, the title teaches students to compare the strengths and weaknesses of Earths animals. The susceptibility of habitats such as Floridas emphasizes the delicacy of the food chain. By analyzing and comparing cases of invasive species, readers discover how humans impact the natural world and the work that must be done to keep the balance.

Download Handbook of Alien Species in Europe Book in PDF, ePub and Kindle
Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.

Download Field Guide to the Amphibians and Reptiles of Britain and Europe Book in PDF, ePub and Kindle
This groundbreaking new guide is an authoritative field reference for these two groups of animals. The taxonomy and systematics of European reptiles and amphibians have changed a lot in recent years, yet there is no modern, up-to-date field guide available that comprehensively covers all the species. The last illustrated field guide to European reptiles and amphibians was first published 38 years ago, and remains outdated despite occasional reprints and new editions. This major new field guide addresses this deficiency. A total of 219 species are covered in detail, with a focus on identification and geographical variation; species texts also cover distribution, habitat and behaviour. Superb colour illustrations by talented artist Ilian Velikov depict every species and all major variations, and colour photographs are also included for most species. The book includes over 370 colour artworks and 200 colour photographs, 155 accurate and up-to-date distribution maps, and easy-to-use keys and tables to help with swift species identification.

Download Reptiles and Amphibians Explained Book in PDF, ePub and Kindle
While reptiles and amphibians are distantly related, these cold-blooded creatures are still distinctively different. Amphibians spend the first part of their lives in the water, then slowly migrate to solid ground. Reptiles hatch from eggs on land. Readers will learn about the similarities and differences between these two groups and test their knowledge to distinguish between the two.

Download The amphibians and reptiles of Luzon Island, Philippines, VIII: the herpetofauna of Cagayan and Isabela Provinces, northern Sierra Madre Mountain Range Book in PDF, ePub and Kindle
Long celebrated for its more than 7,100 islands, the Philippines is a country in Southeast Asia that shares only with Madagascar the distinction of having been designated as both a Megadiverse Nation and a Global Biodiversity Conservation Hotspot. The terrestrial vertebrate fauna of the northeastern Philippines, specifically Luzon Island, has been the subject of intense interest since the first historical explorations. Historically, numerous works considered the biodiversity of Luzon as ?depauperate? in the sense that they was presumed to contain a reduced number of species shared with a continental mainland source. This view has persisted until recently, when a renewed interest in faunistic studies of the northern Philippines has produced a series of notable discoveries, drawing attention to high levels of species diversity and endemism in the northern reaches of the archipelago. We provide the first report on the herpetological biodiversity (amphibians and reptiles) of the northern Sierra Madre Mountain Range, northeast Luzon Island, Philippines. We combine new and historical data, and the results of recent fieldwork, to highlight at least 101 species present in this unique region of the archipelago. Not only is this fauna largely endemic (approximately 70%), but also our results add to a nascent body of literature suggesting that the northern portions of the archipelago may be substantially more diverse than currently appreciated.

Download Freshwater Biodiversity Book in PDF, ePub and Kindle
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
