Snakes of the World: A Catalogue of Living and Extinct Species—the first catalogue of its kind—covers all living and fossil snakes described between 1758 and 2012, comprising 3,509 living and 274 extinct species allocated to 539 living and 112 extinct genera. Also included are 54 genera and 302 species that are dubious or invalid, resulting in recognition of 705 genera and 4,085 species. Features: Alphabetical listings by genus and species Individual accounts for each genus and species Detailed data on type specimens and type localities All subspecies, synonyms, and proposed snake names Distribution of species by country, province, and elevation Distribution of fossils by country and geological periods Major taxonomic references for each genus and species Appendix with major references for each country Complete bibliography of all references cited in text and appendix Index of 12,500 primary snake names The data on type specimens includes museum and catalog number, length and sex, and collector and date. The listed type localities include restrictions and corrections. The bibliography provides complete citations of all references cited in the text and appendix, and taxonomic comments are given in the remarks sections. This standard reference supplies a scientific, academic, and professional treatment of snakes—appealing to conservationists and herpetologists as well as zoologists, naturalists, hobbyists, researchers, and teachers.
This paper is an attempt to do classification on the garter-snake group to help define differences between natural groups and clarify the systematic arrangements.
The Garter Snakes: Evolution and Ecology is the first comprehensive review of the genus Thamnophis in nearly ninety years. The book includes color plates of all species (many never previously figured in color); extensive discussion of ecology, behavior, and captive care; and a modern key to all species - as well as species-by-species summaries of the systematics and natural history of the thirty different garter snakes now recognized. Of particular interest are the descriptions of lesser-known species in Mexico. Because interest in reptiles has grown dramatically in recent years, this comprehensive guide is designed to appeal to as wide an audience as possible - to both the professional herpetologist interested in the biology of Thamnophis and the hobbyist who wants to know more about these diverse and widespread snakes, both in the home aquarium and in the wild. This up-to-date, appealing book, written by the world's leading authorities, will be extremely useful not only to herpetologists but also to conservationists, ecologists, pet owners, and other readers generally interested in natural history.
Documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species.
Recent advances in molecular genetics make the sequencing of genes a straightforward exercise. Comparisons of sequenced genes from different individuals of a species, or from different species, allow the construction of family trees or evolutionary trees which reveal genetic relationships. This volume shows for the first time how those trees, or phylogenies, can be used to answer questions about population dynamics, epidemiology, development, biodiversity, conservation, and the evolution of genetic systems. The techniques for deciding what these new trees can tell us come together in a unified framework so that a common set of methods can be applied, whatever area of biology interests the researcher.
