Anna Allen Wright - Böcker

The preeminent naturalists Albert Hazen Wright and Anna Allen Wright spent years assembling the wealth of material on frogs and toads appearing in this widely used handbook, the third edition of which was originally published in 1949. With abundant black-and-white photographs, colorful descriptions, journal notes from the field, and excerpts from the literature, their personalized natural history emphasizes amphibians observed in the wild. In a foreword to the 1995 paperback edition, Roy McDiarmid, a foremost specialist on frogs and toads, brings the book into historical perspective and supplies information to bring it up to date.Accounts of more than 100 species and subspecies cover such topics as common and scientific names, range, habitat, size, and general appearance, as well as color, structure, voice, and breeding. Separate keys are given for secondary sexual characteristics, eggs, tadpoles, families, and species. Generous quotations from the Wrights' field journals give the reader a sense of the problems and satisfactions of their work.

For years Albert Hazen Wright and Anna Allen Wright traveled extensively, attempting to observe every species of snake in North America in its natural surroundings and collecting data and live specimens. Their exhaustive research resulted in a famous two-volume sourcebook, first published in 1957. Abundantly and painstakingly illustrated by the authors, this personalized natural history organizes for ready reference a wealth of information on American and Canadian snakes.Across the two volumes of Handbook of Snakes of the United States and Canada are accounts of more than three hundred species and subspecies, accompanied by photographs, drawings, and distribution maps. Generous excerpts from the authors' field journals give the reader a vivid feeling of some of the satisfactions and conclusions of the Wrights' search.Volume I features an introductory section in which the Wrights cover snake names and such features of their biology and behavior as range, size, longevity, distinctive characteristics, color, habitat, period of activity, breeding, ecdysis, food, venom and bite, and enemies. It also includes an informative new foreword written for the 1994 reprint edition by Jonathan A. Campbell, a leading expert on snakes. The main section of Volume I comprises in-depth accounts of twenty-nine snake species, from Leptotyphlopidae (blind snakes) to Opheodrys (green snakes).Volume II includes species accounts of nineteen species, from Oxybelis (pike-headed tree snakes) to Sistrurus (ground rattlesnakes, pigmy rattlesnakes, and massasaugas), as well as a glossary and an index for both volumes
