This book was released on 1996-03-31 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume sets out to provide an overview of recent research on all aspects of amphibian ecology and behaviour and to illustrate its application to practical conservation measures for this major group of animals. Its broad scope makes it of relevance to students of general biology, ecology and conservation, but also to professionals in industries and agencies involved with environmental issues and nature conservation.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the history of amphibian conservation and research in Britain. It is packed with unique insights from the author who, in the late 1960s, was probably Britain’s first professional amphibian conservationist. At that time, the situation for amphibians was extremely serious after three decades of population decline. Up to the 1990s, Arnold Cooke was directly involved in understanding and trying to remedy the situation via research, legislation and active conservation. He initiated long-term monitoring, surveillance and studies that continued well into this century. This research developed and utilised simple monitoring techniques, such as counting breeding newts at night or toads dead on roads. The resulting datasets also proved of value in determining whether breeding behaviour was affected by climate change. This personal overview charts in detail how amphibian conservation developed from a relatively low knowledge base with few individuals involved to an abundance of information available for the many groups of people now active in the field. It includes published, unpublished and no longer readily accessible material, to emphasise how contemporary knowledge, attitudes and resources affected what was done and what happened as a result. Various policies, strategies, laws and other initiatives have helped stop or slow declines, but the future is still uncertain. The book will appeal to a broad readership, from naturalists to professional herpetologists. Furthermore, this story will have relevance for amphibian conservation in other countries in light of their more recent widespread declines. It is also of interest to those wanting to know more about the development of wildlife conservation in Britain.

This book was released on 2009 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis documented and explored empirical data on populations of natterjack toads (Bufo calamita Laurenti), a pond-breeding amphibian particularly vulnerable to climate change, habitat degradation and fragmentation. The research used data collected in the field (census and environmental data, mark-recapture study) to assess the spatiotemporal dynamics of toad populations at local (2-5km) and regional (>10km) scales, to identify the local environmental determinants of toad breeding activity and success and to assess the movement patterns of juvenile and adult toads within and between breeding sites. There was no synchrony in the toad breeding activity and success at the local level, suggesting that populations function as individual clusters independent of each other, with little or irregular dispersal among populations. Regional synchrony in both rainfall and temperature probably explain the observed regional synchrony in the number of egg strings (used as a surrogate for adult breeding female population size). Using a model selection approach, results indicated that the abundance and diversity of predators of tadpoles were the most influential factors on toad reproductive success. A 46-day mesocosm experiment indicated that the presence of B. calamita tadpoles and their predators (here the dragonfly Sympetrum striolatum larvae) could enhance the functioning of pond ecosystems through both direct and indirect effects, in particular through increases in decomposition rates and enhanced secondary production. Several aspects of the research suggested that some of the toad populations were structured as source-sink populations, where the viability of local populations in sink habitats relies on immigration from source areas. The maintenance of a network of ponds within the dispersal range of species is therefore essential to ensure the long-term viability of amphibian populations, especially for those species (e.g. B. calamita) breeding in temporary ponds.
