Cusco Amazónico

"Assays of assemblages of amphibians and reptiles provide important information on community structure in the tropics. These ectothermic organisms are highly responsive to slight differences in the environment and to seasonal differences, such as patterns of rainfall. Most species seem to have rather restricted home ranges; therefore, data gathered in a restricted area provide much better insight into the requirements of, and potential interactions among, the species in the assemblage."?from the Introduction The rainforests in the southwestern part of the Amazon Basin in southeastern Peru are home to scores of amphibians and reptiles. Cusco Amazónico is a richly illustrated and comprehensive account of the lives of 151 of these species. William E. Duellman's masterpiece of community ecology includes descriptions of the physical environment and vegetation found in this unique habitat along with syntheses of abundance, mass, feeding, reproductive guilds, and daily and seasonal patterns of activity. Identification keys in English and Spanish precede detailed and illustrated species accounts. Tadpoles of many frogs are described and illustrated. Cusco Amazónico will become a standard reference for herpetologists, tropical biologists, biogeographers, ecologists, and conservationists and stands on its own as a portrait of an animal community in a unique bioregion. The illustrations include 236 color photographs, 121 charts and graphs, 16 maps, 42 line drawings, 2 halftones, and 56 sets of audiospectrograms and waveforms. There are 71 tables.

Amphibians and Reptiles of Baja California, Including Its Pacific Islands and the Islands in the Sea of Cortés

The Baja California peninsula is home to many forms of life found nowhere else on earth. This, combined with the peninsula's rugged and inaccessible terrain, has made the area one of the last true biological frontiers of North America. L. Lee Grismer is not only the foremost authority on the amphibians and reptiles of Baja California, but also an outstanding photographer. He has produced the most comprehensive work on the herpetofauna of the peninsula and its islands ever published. With its stunning color images, detailed accounts of many little-known species, and descriptions of the region's diverse environment, this is the definitive guide to the amphibians and reptiles of a fascinating and remote region. The culmination of Grismer's quarter century of fieldwork on the Baja peninsula and his exploration of more than one hundred of its islands in the Pacific Ocean and the Sea of Cortés, this book gives information on the identification, distribution, natural history, and taxonomy of each species of amphibian and reptile found there. Preliminary accounts of the life history of many of the salamanders, frogs, toads, turtles, lizards, and snakes are reported here for the first time, and several species that were almost unknown to science are illustrated in full color. The book also contains new data on species distribution and on the effect of the isolated landscape of the peninsula and its islands on the evolutionary process. Much of the information gathered here is presented in biogeographical overviews that consider the extremely varied environments of Baja California in both a contemporary and a historical framework. An original and important contribution to science, this book will generate further research for years to come as it becomes a benchmark reference for both professionals and amateurs.
