Herpetology has always been one of the most exciting disciplines of zoology. During the past few years the field has continued to grow, yet it has been plagued by scarcity of comprehensive, up-to-date textbooks containing the most important developments. This timely book fills that void. Through skillful synthesis, the author summarizes the diversity in the biology of living amphibians and reptiles and describes the breadth of current herpetological research. Topics covered include the evolution, classification, development, reproduction, population, and environmental issues surrounding the study of amphibians and reptiles. Designed as an advanced undergraduate textbook, Herpetology is a valuable resource for students, practitioners, and interested amateurs alike. Provides an incisive survey and much needed update of the field Emphasizes the biological diversity among amphibians and reptiles Details the most recent research findings, citing ke

"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 IntroductionThe 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.

Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils. This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

The objective of this guidance on fulfilling the reporting requirements of Article 12 of the Code of Conduct is to obtain a regular flow of information on its observance to strengthen implementation of the Code, to provide data for its future revisions and improvement, and, most importantly, to improve the protection of human health and the environment related to pesticide use and management in agriculture and public health. The guidance was prepared in compliance with the FAO/WHO International Code of Conduct on Pesticide Management, which sets out a framework and voluntary standards of conduct for stakeholders in pesticide management, in particular governments and the pesticide industry. Endorsed by FAO, WHO, governments, pesticide producers, non-governmental organizations and other stakeholders, the Code outlines their shared responsibility to promote best practice and risk reduction throughout the pesticide life cycle. The Code of Conduct thereby establishes the commitment and moral obligation of stakeholders to comply with the agreed standards of conduct and to assume their respective responsibilities. These include governments’ responsibility to promote pesticide risk reduction and the industry’s responsibility to produce products that are adapted to the context of their use and to provide stewardship of those products throughout their life cycle. This guidance was prepared with the support of the FAO/WHO Joint Meeting on Pesticide Management (JMPM) to provide further guidance on the provisions of the Code of Conduct related to its observance and implementation. It reflects the joint FAO/WHO approach to pesticide management, thus addressing the topic in both agricultural and public health settings.

For generations, the map has been central to how societies function all over the world. Cybercartography is a new paradigm for maps and mapping in the information era. Defined as “the organization, presentation, analysis and communication of spatially referenced information on a wide variety of topics of interest to society, cybercartography is presented in an interactive, dynamic, multisensory format with the use of multimedia and multimodal interfaces. Cybercartography: Theory and Practice examines the major elements of cybercartography and emphasizes the importance of interaction between theory and practice in developing a paradigm which moves beyond the concept of Geographic Information Systems and Geographical Information Science. It argues for the centrality of the map as part of an integrated information, communication, and analytical package. This volume is a result of a multidisciplinary team effort and has benefited from the input of partners from government, industry and other organizations. The international team reports on major original cybercartographic research and practice from a variety of disciplinary perspectives, including the humanities, social sciences including human factors psychology, cybernetics, English literature, cultural mediation, cartography, and geography. This new synthesis has intrinsic value for industries, the general public, and the relationships between mapping and the development of user-centered multimedia interfaces. * Discusses the centrality of the map and its importance in the information era * Provides an interdisciplinary approach with contributions from psychology, music, and language and literature * Describes qualitative and quantitative aspects of cybercartography and the importance of societal context in the interaction between theory and practice * Contains an interactive CD-Rom containing color images, links to websites, plus other important information to capture the dynamic and interactive elements of cybercartography

The Convention on International Trade in Endangered Species (CITES) is the best known and most controversial of international conservation treaties. Since it came into force 25 years ago, debate has raged over its most basic assumptions. CITES treats the international trade in wildlife as the most important threat to the continued existence of wild species. It offers a prescription of trade bans and restrictions for endangered species. However, it is now generally acknowledged that for most species habitat loss is a much more significant threat. Some argue that the CITES remedy actually exacerbates the problem by removing the incentive to conserve wildlife habitat. This collection of essays, the first of its kind, charts the controversies and changes within CITES. It provides case studies of the way CITES has dealt with particular species and notes the growing role of the South in shaping the direction of the treaty. It considers the role of sustainable use, the precautionary principle and unilateralism within CITES. Finally, it examines options for the future of CITES. Implicit within a number of the contributions is the recognition that questions of wildlife conservation cannot be divorced from wider issues of land use, development and social justice. This book provides an essential resource for policy makers, practitioners, academics and students concerned with conservation, development and trade.
