Available in PDF, EPUB and Kindle. Book excerpt: Amphibians of Central and Southern Africa is the first comprehensive guide to the frogs, toads, and caecilians of the ten sub-equatorial African countries—Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe. The result is at once a valuable reference tool, a field guide, and a source of ideas for future research.A source of increasing interest in their own right, amphibians are also benchmark species for biodiversity, and are used as laboratory animals in many of the sciences. In the wild, amphibians, especially frogs, act as natural monitors of water quality and are invaluable in pest control. Their skins secrete a wide range of pharmacologically active substances, such as antibiotics and painkillers. Yet frog populations are declining worldwide, mainly due to human destruction of their habitats. Alan Channing synthesizes information published over the last century to provide the first natural history and a portrait of the amphibian fauna of this vast region.Key features of Amphibians of Central and Southern Africa include*detailed accounts for 205 species of frogs and toads (and 2 species of caecilian) accompanied by color illustrations, distribution maps, details of breeding and tadpole behavior, and call descriptions*illustrations and tadpole identification keys for each genus*special sections for some species with topics such as "skin toxins"*an overview of fossil frogs, a discussion of humankind and frogs in Africa, and a bibliography of African frog biology

Book excerpt: "Amphibians are facing an extinction crisis, but getting to the facts has been difficult. "Threatened Amphibians of the World" is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians. All 1,900 species known to be threatened with extinction are covered, including a description of threats to each species and an evaluation of conservation measures in place or needed. Each entry includes a photograph or illustration of the species where available, a distribution map, and detailed information on range, population and habitat and ecology. Introductory chapters present a detailed analysis of the results, complemented by a series of short essays written by many of the world's leading herpetologists. Appendices include annoted lists of lower risk species and a country-by-country listing of threatened amphibians."--pub. desc.
