"To those who have carried out research at La Selva, as well as for the serious layperson or even a first-time ecotourist, this book will be a delight. Many of these species will be seen along forest trails or in clearings nearly every day. The beauty of this splendid guide is its concise but authoritative coverage. Guyer and Donnelly have been carrying out research at La Selva for more than 25 years and have contributed much new information on the lives of these animals. A great strength is the series of keys based primarily on live coloration for rapid and accurate identification in the field. The added value is that the book covers 90% of the amphibians and reptiles found in the Caribbean lowlands from northeastern Honduras to and including Bocas del Toro Province, Panama. In sum, my words for this book are: 'Mighty Fine'! "--Jay M. Savage, author of The Amphibians and Reptiles of Costa Rica "A 40-year intensive look, precisely what we all wished we had had when we first stepped into the Neotropical rainforest. Cleanly written, in a language easily accessible to the citizen naturalist . . . . and coupled with the essential many good color photos, this book is THE herpetological starting point for any naturalist, biodiversity manager, and scientist exploring lowland Central American rainforest. It superbly complements Savage's country-wide coverage."--Daniel H. Janzen, editor of Costa Rican Natural History "This book is an important contribution to our understanding of the herpetofauna of one of the world's foremost tropical field stations. It represents an essential step toward easy field identification of an important group of tropical vertebrates. It will serve as a stimulus and set the standard, not only for herpetologists, but for students of other groups interested in producing easily used, attractive guides to local faunas and floras."--Don E. Wilson, Senior Scientist, Smithsonian Institution, and Chairman of the Board, Organization for Tropical Studies
