Описание: 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 oudated 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. This groundbreaking new guide will become the definitive field reference for these two groups of animals.
It includes:- Over 370 colour artworks and 200 colour photographs- 155 accurate and up-to-date distribution maps- Easy-to-use keys and tables to help with swift species identification

Описание: Florida is home to a more diverse variety of amphibians and reptiles than any other state due to its wide array of ecosystems - from pine forests to the subtropical Everglades to the tropical Keys - and its large number of established nonnative species. This volume is a comprehensive account of the 219 species known to exist in the state.

Описание: 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.

Описание: This 176-page title with 240 colour photographs is the only pet owner/breeder reference on health and diseases in reptiles and amphibians in captivity.
All aspects regarding the captive care of snakes, pythons, lizards, turtles and frogs are presented in a simple-to-follow layout.
The 240 colour images show examples of typical health problems to assist the herpetologist in recognising signs as well as information about the treatment or action to take to rectify or reduce the spread of disease and support the reptile/amphibian back to good health.
Too many ill animals are presented to veterinarians by keepers who are mortified when they realise that, through their lack of understanding of correct housing, hygiene, heating, lighting, feeding and breeding procedures, they may have contributed to the onset of disease in the animal in their care. Although this is not always the case, a large percentage of sick pythons, lizards, turtles and frogs are due to incorrect management.
Become informed to prevent health problems from entering your collection. Furthermore, become better equipped to recognise signs of illness before further development may prohibit a return to good health.
This book is an essential reference for any responsible keeper of reptiles and amphibians.

Описание: Amphibians: Biology, Ecology and Conservation opens with a review of the current knowledge on the Harderian gland of anuran amphibians. The Harderian gland is an orbital gland present in all vertebrates possessing nictitating membrane, with the primordium of the Harderian gland appearing during metamorphosis throughout the development of the nictitating membrane. The authors go on to discuss D-Aspartate (D-Asp), an excitatory amino acid involved in the synthesis of sex steroid hormones. High concentrations of D-Asp were found in the gonads, in the brain and in the Harderian gland of the green frog, Pelophylax esculentus. The current knowledge on the D-Asp in gonads and in tissues during the seasonal reproductive cycle is reviewed. Since D-Asp modulates sex hormone synthesis, this book correlates the local amino acid levels with serum and local sex hormone concentrations. Next, the authors report on the existing work on the steroidogenic pathways activated in reproductive and post-reproductive phases in both testis and brain in the aforementioned green frog. Plasma testosterone levels are low in the non-breeding period and high during the breeding period, while 17β-estradiol levels illustrate a contradictory trend. This study indicates a close correlation between steroidogenic process in the testis and in the brain, suggesting a synergic mechanism of regulation. The concluding chapter presents three case studies that demonstrate how the life cycle of the giant toad, Rhinella marina, as well as its somatic and hepatosomatic index, voracious appetite and highly permeable skin make it a species susceptible to the bioaccumulation of organic and inorganic pollutants and their toxicological effects. Due to these characteristics, R. marina is considered to be a good biomonitor of environmental pollution.

Описание: Experimental approaches to auditory research make use of validated animal models to determine what can be generalized from one species to another. To address broader comparative issues, this book treats both fish and amphibians together, to overcome the differing theoretical and experimental paradigms that underlie most work on these groups.
