Book Synopsis Ecotoxicology and Genotoxicology by : Marcelo L Larramendy
Download or read book Ecotoxicology and Genotoxicology written by Marcelo L Larramendy and published by Royal Society of Chemistry. This book was released on 2017-06-15 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential impact of anthropogenic pollutants such as agrochemicals on the environment is of global concern. Increasing use of certain compounds can result in contamination of food, water and atmospheric systems and in order to combat this pollution it is important to be able to accurately monitor the short and long term effects. This book describes the latest non-traditional terrestrial species models used as indicators of the toxic effects of environmental pollutants. The book enables understanding of the effects of pollutants in non-target species, and therefore enables analysis of the effects on ecosystems. This book will be of interest to anyone interested in developing new biomarker species with high degrees of ecological relevance. It will serve as a useful resource for regulatory and research toxicologists, particularly those interested in soil screening and the effects of pollutants on wildlife and insects and their use as biological indicators.

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 Frogs of the Fitzingeri Group of Eleutherodactylus in Eastern Panama and Chocoan South America (Leptodactylidae) by : John D. Lynch
Download or read book Frogs of the Fitzingeri Group of Eleutherodactylus in Eastern Panama and Chocoan South America (Leptodactylidae) written by John D. Lynch and published by . This book was released on 1983 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Based on field data and on examination of more than 3000 preserved specimens, species limits and distributions are defined for the frogs currently assigned to the fitzingeri group of Eleutherodactylus in the Chocoan lowlands (mainly below 1000 m. elev. in eastern Panama, western Colombia, and western Ecuador). Several of the species are abundant, ecologically important animals that have been repeatedly confused in the literature. Nine species are treated in detail and described and illustrated from living as well as preserved material, with natural history notes added where possible. Eleutherodactylus achatinus (Boulenger) occurs from Panama south to southwestern Ecuador; the names E. brederi Dunn and Hylodes pagmae are assigned to its synonymy (although brederi might yet prove to be a valid sibling species with a different call). Eleutherodactylus caprifer Lynch is known from west-central Colombia and northwestern Ecuador. These two species lack appreciable toe webbing. The following four species have moderate toe webbing: Eleutherodactylus fitzingeri (O. Schmidt) occurs from Nicaragua to west-central Colombia, being here treated primarily in the southern part of its range, where it has been confused with Eleutherodactylus raniformis (Boulenger)--a larger frog that occurs from eastern Panama south to west-central Colombia. Eleutherodactylus longirostris (Boulenger) occurs from the Darién highlands of extreme eastern Panama throughout western Colombia to southern Ecuador. All previous reports of longirostris in lower Central America seem to have been based on specimens either of fitzingeri or especially of Eleutherodactylus crassidigitus Taylor, whose range is extended out of Costa Rica and throughout the Isthmus of Panama to the Colombian border. However, the variation of crassidigitus remains inadequately studied and the redefined species might be a composite. E. crassidigitus differs from longirostris in color pattern, smaller size, and in a greater extent of toe webbing, although all specimens do not show these differences to the same degree. A closer relative (sister species) of longirostris may be the Central American E. talamancae Dunn. The remaining three species are streamside frogs having extensive toe webbing: Eleutherodactylus anomalus (Boulenger) is common in western Colombia and northwestern Ecuador. Eleutherodactylus anatipes, new species, is known only from northwestern Ecuador, and Eleutherodactylus zygodactylus, new species, is described from west-central Colombia. The fitzingeri group of Eleutherodactylus is especially diverse in the Chocoan lowlands. At most localities in South America, only two or three species are ever sympatric, but west of the Andes as many as seven species of the group co-occur in geographic sympatry, with species density being greatest in the region of the Río San Juan drainage of Colombia. Natural history data are fragmentary. The vocalizations and/or calling behavior of several species have characteristics that may reduce the frogs' vulnerability to sound-responsive predators"--P. 484.

Book Synopsis The Physical Geography of South America by : Thomas T. Veblen
Download or read book The Physical Geography of South America written by Thomas T. Veblen and published by Oxford University Press. This book was released on 2015-12-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge about this mostly tropical continent, together with its high mountains and temperate southern cone. The authors systematically cover the main components of the South American environment - tectonism, climate, glaciation, natural landscape changes, rivers, vegetation, animals, and soils. The book then presents more specific treatments of regions with special attributes from the tropical forests of the Amazon basin to the Atacama Desert and Patagonian steppe, and from the Atlantic, Caribbean, and Pacific coasts to the high Andes. Additionally, the continents environments are given a human face by evaluating the roles played by people over time, from pre-European and European colonial impacts to the effects of modern agriculture and urbanization, and from interactions with El Ni?o events to prognoses for the future environments of the continent.

Book Synopsis Marsupial Frogs by : William E. Duellman
Download or read book Marsupial Frogs written by William E. Duellman and published by JHU Press. This book was released on 2015-10-15 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first major synthesis of marsupial frogs, this book is the magnum opus of renowned herpetologist William E. Duellman. This scientific masterpiece reveals many aspects of the lives of marsupial frogs and closely allied genera. Native to Central and South America, these amphibians differ from other frogs in that they protect their eggs after oviposition by either adhering them to the female’s back or placing them in a specialized dorsal pouch (thus the common name, marsupial frog). During mating, the male typically collects the eggs from the female with his feet—often one at a time and always out of water—fertilizes them, and then tucks them into the female’s pouch or attaches them to her back. In some species these eggs hatch as tadpoles, but most emerge as miniatures of the adults. Even among the tadpoles there is remarkable divergence, with some behaving in the typical manner (feeding and metamorphosing), whereas others forego all feeding until they metamorphose. In Marsupial Frogs, William E. Duellman’s synthesis of all that is known about the unique family Hemiphractidae is largely based on decades of his own careful laboratory and field study. He reveals the diversity of exotic color patterns and the frogs' geographic distributions by providing more than 200 photographs, illustrations, and maps. This exceptional tome should find its way into the libraries of serious herpetologists, tropical biologists, and developmental biologists. Included in this book are • A molecular phylogeny of the family Hemiphractidae • A thorough osteological analysis • A review of external morphological features • An overview of the evolution of reproductive modes • A biogeographic synthesis • Keys to genera and species • Diagnosis and thorough description of each species of marsupial frog • Colored physiographic maps depicting species distributions
