The amphibian fauna of Mesoamerica is one the most diverse, yet the most endangered in the area, perfectly exemplifying why the region is one of the world biodiversity hotspots. I carried out analyses from three interrelated perspectives: Conservation Genetics, species delimitation and Comparative Phylogeography of two genera of the family Hylidae in most of Mesoamerica: Agalychnis and Dendropsophus. First I performed a species delimitation analysis for the genus Agalychnis, with the specific aim of testing for cryptic diversity within the species A. callidryas, which exhibits wide morphological variation and the uncertainty of whether or not it represents more than one species has not been solved. Secondly, I did a conservation analysis of the genus Agalychnis adopting a comparative approach between endangered and non-endangered species and integrating ecological modelling and genetic information, with the aim of gathering key information for a better management and conservation planning at a regional scale of this genus in particular and Hylid frogs in general. This analysis resulted in the suggestion of short-term alternatives for conservation of critically endangered species and the management of non-endangered species at regional scale. Finally, I applied a comparative phylogeographic analysis between the two genera Agalychnis and Dendropsophus with the general objective of identifying factors and processes underlying species origin and dispersal within Mesoamerica. I proposed hypotheses for the colonization and dispersal of species of these two genera within Mesoamerica, on the basis of genetic data, geographical information, and ecological niche modelling. As part of data gathering for the latter analysis a new country record leading to the considerable extension of the geographical distribution of D. phlebodes is reported.

Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

"Illuminated by the same joyful curiosity and erudition, lyric writing, and plain love of life that made a classic of Archie Carr's The Windward Road."--Peter Matthiessen "Archie Carr shows that he can write about people and forests engagingly and accurately without recourse to fake adventures or gringo condescension."--New York Times Archie Carr's story is his love for the rural high tropics of Central America, revealed with grace and humor in the personal account of the years (1945-49) that he spent in Honduras with his family as a teacher at the Agricultural School run by the United Fruit Company. High Jungles and Low has four parts, each written in a distinctive style. "The Land" is descriptive and includes a candid chapter on Yankee relations with Latin America. "People in the Land" is anecdotal, with sketches of the hill people of Honduras. "The Sweet Sea," a short history of Nicaragua, reveals the biological drama of four centuries of turmoil in that country. "Hall of the Mountain Cow" is Carr's one-month diary of a 100-mile walk along the Mosquito Shore, the rain forest of the Caribbean coast.

In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.

"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.

In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."
