Book Description
Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.

Book Description
The allure of owning an American Bullfrog (Lithobates catesbeianus) as a pet extends well beyond the usual realm of domestic animals. This comprehensive study delves into the history of the American Bullfrog and its varied attractiveness, making it a fascinating choice for anybody seeking an interesting and engaging companion. 1. Context The diverse range of habitats in which the native American bullfrog has evolved is closely related to its complicated evolutionary past. By tracking the species' evolutionary history, we are able to comprehend the adaptation mechanisms that have allowed this amphibian species to prosper in a range of habitats, including freshwater ponds, marshes, and even urban areas. Knowing the American Bullfrog's role in the environment will help you understand its reflexes and intrinsic behaviors. The bullfrog's capacity to control insect populations via predation and its distinctive calls that echo across wetlands demonstrate its vital role in maintaining ecological balance. Examining how it interacts with other species in its home habitat can reveal insights into the intricate web of interactions that constitutes the natural world.

Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Book Description
Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society

Book Description
The American bullfrog, scientifically known as Lithobates catesbeianus, is one of the largest frog species native to North America. With its distinctive deep green coloration and prominent tympanum (ear drum) behind each eye, it is easily recognizable. These amphibians are known for their loud, deep croaking calls, which are often heard during the breeding season. American bullfrogs are highly adaptable and can be found in a variety of aquatic habitats, including ponds, lakes, and slow-moving streams. They are voracious predators, feeding on insects, small fish, crustaceans, and even small mammals. Due to their hardiness and ability to thrive in a range of environments, American bullfrogs have been introduced to many parts of the world outside their native range, sometimes causing ecological disruptions as an invasive species.

Book Description
“A huge, beautiful compendium of 600 frogs from around the world, from the famed poison-arrow variety on up to the intriguingly named plaintive rain frog.” —Wired With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world. “If you are a serious (and I mean serious) fan of the frog, you are in for a real treat.” —Boing Boing
