As in a field guide, the amphibians and reptiles are described in detail to aid identification. The text goes far beyond a simple field guide, however, containing substantial treatment of the habitat, habits, reproduction, and distribution of each species with additional remarks on taxonomic status, behavior, appearance and conservation. Color photos of each species are included. Two of the authors are curators for museums of natural history, the third teaches biology at Indiana U. of Pennsylvania. c. Book News Inc.
Book Synopsis Biogeographic Patterns of South American Anurans by : Tiago S. Vasconcelos
Download or read book Biogeographic Patterns of South American Anurans written by Tiago S. Vasconcelos and published by Springer Nature. This book was released on 2019-08-28 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.
Book Synopsis Distribution Patterns of Reptiles and Amphibians in Puerto Rico by : Minh Duc Le
Download or read book Distribution Patterns of Reptiles and Amphibians in Puerto Rico written by Minh Duc Le and published by . This book was released on 1999 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the question of whether a big island can be divided into many smaller islands with the same pattern of area-species curve as that of the complete island. To address this question, this study used data on the number and distribution of amphibians and reptiles on Puerto Rico and landbridge islands of the Puerto Rican Bank, which were fragmented from the big island about 10,000 years ago. In Puerto Rico, the data show correlations between the number of species and area available at different elevation levels and between species and area after removing effects of elevation. These patterns are different from the patterns of correlation between area and the number of reptiles and amphibians on 29 islands on the Puerto Rican Bank. The area-species curves of the elevationally and areally subdivided "islands" on Puerto Rico tend to have steeper slopes than the curves of the Puerto Rican Bank islands. Analyses of area and the number of those species on fragmented habitat islands at different elevations also indicated correlation between them. However, patterns of correlation seem not to be the same at each altitude. The slope of the area-species curve seems to decrease with increasing elevation levels. Other patterns of species distribution of Puerto Rico's herpetofauna are: there are linear relationships between the number of species and elevation, the number of species and distance from the coast, and the number of species and the species range areas. Multiple regression analyses of three variables: area, precipitation, and elevation, suggested that variation of species distribution in Puerto Rico is partly caused by interactions among these variables. Elevation plays an especially important role in explaining reptile and amphibian distribution. The rainfall variable had the least effect on determining herpetofauna diversity. The study results suggest that area-species correlation is a consequence of habitat heterogeneity on the island.

Book Synopsis The Amphibians and Reptiles of Costa Rica by : Jay M. Savage
Download or read book The Amphibians and Reptiles of Costa Rica written by Jay M. Savage and published by University of Chicago Press. This book was released on 2002-08 with total page 1076 pages. Available in PDF, EPUB and Kindle. Book excerpt: World renowned for its biological diversity and model conservation system, Costa Rica is home to a wide variety of amphibians and reptiles, from the golden toad to the scorpion lizard and the black-headed bushmaster. Jay M. Savage has studied these fascinating creatures for more than forty years, and in The Amphibians and Reptiles of Costa Rica he provides the most comprehensive, up-to-date treatment of their biology and evolution ever produced. Savage begins with detailed discussions of the natural and cultural history of Costa Rica, setting the stage for a detailed treatment of each of the 396 species of amphibians and reptiles that may be found there. Each species account synthesizes and analyzes everything that is known about the animal's anatomy, behavior, geographic distribution, systematics, and evolutionary history and provides keys for identifying amphibians and reptiles in the field. In addition to distribution maps and systematic and morphological illustrations, the book includes color photographs of almost every known species, many taken by the distinguished nature photographers Michael and Patricia Fogden. Because Costa Rica has played, and continues to play, a pivotal role in the study of tropical biology as well as in the development of ecotourism and ecoprospecting, and because more than half of the amphibians and reptiles in Costa Rica are also found elsewhere in Central America, The Amphibians and Reptiles of Costa Rica will be an essential book for a wide audience of nature lovers, naturalists, ecotourists, field biologists, conservationists, and government planners.

Book Synopsis Evolutionary Biogeography by : Juan Morrone
Download or read book Evolutionary Biogeography written by Juan Morrone and published by Columbia University Press. This book was released on 2009 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rather than favoring only one approach, Juan J. Morrone proposes a comprehensive treatment of the developments and theories of evolutionary biogeography. Evolutionary biogeography uses distributional, phylogenetic, molecular, and fossil data to assess the historical changes that have produced current biotic patterns. Panbiogeography, parsimony analysis of endemicity, cladistic biogeography, and phylogeography are the four recent and most common approaches. Many conceive of these methods as representing different "schools," but Morrone shows how each addresses different questions in the various steps of an evolutionary biogeographical analysis. Panbiogeography and parsimony analysis of endemicity are useful for identifying biotic components or areas of endemism. Cladistic biogeography uses phylogenetic data to determine the relationships between these biotic components. Further information on fossils, phylogeographic patterns, and molecular clocks can be incorporated to identify different cenocrons. Finally, available geological knowledge can help construct a geobiotic scenario that may explain how analyzed areas were put into contact and how the biotic components and cenocrons inhabiting them evolved. Morrone compares these methods and employs case studies to make it clear which is best for the question at hand. Set problems, discussion sections, and glossaries further enhance classroom use."--Publisher's description.
Book Synopsis Status and Conservation of Midwestern Amphibians by : Michael J. Lannoo
Download or read book Status and Conservation of Midwestern Amphibians written by Michael J. Lannoo and published by . This book was released on 1998 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1990 an international group of biologists, meeting to discuss rumors of declines in the number of amphibians, discovered that amphibian disappearances once thought to be a local problem were not -- the problem was global. And, even more disturbing, amphibians were disappearing not just from areas settled by humans but from regions of the world once believed to be pristine. Under the mantle of the Declining Amphibian Populations Task Force, this timely book addresses three fundamental questions for the midwestern United States: are amphibians declining; if so, why; and, if so, what can be done to halt these losses? In the Midwest -- defined here as Missouri, Iowa, Illinois, Indiana, Ohio, Minnesota, Wisconsin, and Michigan -- there can be no doubt that the number of salamanders and frogs has declined with EuroAmerican settlement and the conversion to an agriculturally dominated landscape. Habitat loss and landscape fragmentation have been major factors in this decline, as have aquacultural uses of natural wetlands. Bullfrog introductions have eliminated populations of native amphibians, and collecting for the biological supply trade has reduced the number of individuals within many populations. The goal of the forty-two essays in this well-documented, well-illustrated book is to put between two covers all we know now about the status of midwestern amphibians. By doing this, the editor has created a readily accessible historical record for future studies. Organized into sections covering landscape patterns and biogeography, species status, regional and state status, diseases and toxins, conservation, and monitoring and applications, this landmark volume will serve as the foundationfor amphibian conservation in the Midwest.

This book was released on 2023-02-28 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: An expansive and detailed review of the biology of Caribbean amphibians, considering their threats, conservation and outlook in a changing world. Amphibians are the group of vertebrates undergoing the fastest rate of extinction; it is urgent that we understand the causes of this and find means of protecting them. This landmark illustrated volume brings together the leading experts in the field. As well as offering an overview of the region as a whole, individual chapters are devoted to each island or island-group and the measures used to protect their amphibians through legislation or nature reserves. The biological background of insular biogeography, including its methods, analysis and results, is reviewed and applied specifically to the problems of Caribbean amphibians – this includes a re-examination of patterns and general ideas about the status of amphibians in the Anthropocene. The Conservation and Biogeography of Amphibians in the Caribbean offers an important baseline against which future amphibian conservation can be measured in the face of climate change, rising sea level and a burgeoning human population. Covers over 300 species.
Book Synopsis Extinction in Our Times by : James P. Collins
Download or read book Extinction in Our Times written by James P. Collins and published by Oxford University Press. This book was released on 2009-07-07 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.

Book Synopsis Sexual Segregation in Ungulates by : R. Terry Bowyer
Download or read book Sexual Segregation in Ungulates written by R. Terry Bowyer and published by JHU Press. This book was released on 2022-11-15 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why does it benefit some male and female animals to live separately? Sexual segregation, wherein the sexes of a species live apart for long periods of time, has far-reaching consequences for the ecology, behavior, and conservation of hooved mammals, which are called ungulates. Award-winning researcher R. Terry Bowyer has spent the past four decades unravelling the causes and consequences of this perplexing phenomenon by studying ungulates and the large carnivores that prey upon them. In Sexual Segregation in Ungulates, Bowyer's critical, thought-provoking approach helps resolve long-standing disagreements concerning sexual segregation and offers future pathways for species and habitat conservation. He highlights important elements of the natural history of wild ungulate species, including bighorn sheep and elk. He then uses this perspective to frame and test hypotheses illuminating the motivations behind sexual segregation. He investigates the role of sexual segregation in mechanisms underpinning ungulate mating systems, sexual dimorphism, paternal behavior, and population dynamics. Bowyer's research spans ecosystems from deserts to the Arctic and involves most species of ungulates inhabiting the North American continent. He also provides a timely review of sexual segregation for species of plants and other animals, including humans. Covering definitions, theory, findings, and practical applications of related study, Bowyer describes the behavioral patterns related to sexual segregation, explains how to detect these patterns, and considers the implications of sexual segregation for new approaches to conservation and management of ungulates and other species of wildlife. This book is essential reading for scientists and all those interested in the conservation and management of species, including wildlife professionals, hunters, outdoor enthusiasts, and naturalists.
