Available in PDF, EPUB and Kindle. Book excerpt: There are many famous wetlands in the world that have been deemed important for the homeostasis ofthe biosphere and accorded some form ofprotected status in view of the richness of their flora and fauna. T}1e Pantanal, located almost directly in the center ofthe South American continent, is among the largest such wetlands in the world. It is, in fact, the largest wetland that is still in a nearly natural state and has not been extensively modified by man for agriculture. The extent of the region covered by flood waters at the end of each rainy season varies from year to year, sometimes considerably, so estimates of the exact area it occupies have varied enormously. The size of the 2 2 Pantanal has been reported to be between 80,000 km (Bonetto, 1975) and 250,000 km (Tundisi and Matsumura-Tundisi, 1985). The most co~on1y accepted estimates at the present time are approximately 130,000 to 140,000 km , supported by estimates made from Nimbus-7 satellite observations (Hamilton et al. , 1996). However, Por (1995) suggested that the area extending into Bolivia and Paraguay has not been satisfactorily 2 surveyed, leading him to accept the figure of 200,000 km as the area of the entire Pantanal, ineluding all of its extensions. The main reason for the year to year variation in the extent of the flooding is the considerable difference in timing of the rainfall on the watershed.

Book excerpt: An understanding of gonorynchiform morphology and systematic inter- and intra-relationships has proven vital to a better understanding of the evolution of lower teleosts in general, and more specifically of groups such as the clupeiforms (e.g., herrings and anchovies), and ostariophysans (e.g., carps, minnows and catfishes).

This book was released on 2003-11-30 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals have been studied for centuries. But what are the most important and relevant reference and information sources in the zoological sciences? This work is a comprehensive, thoroughly annotated directory filled with hundreds of esteemed resources published in the field of zoology, including indexes, abstracts, bibliographies, journals, biographies and histories, dictionaries and encyclopedias, textbooks, checklists and classification schemes, handbooks and field guides, associations, and Web sites. A complete revision of the award-winning Guide to the Zoological Literature: The Animal Kingdom (1994), this new title includes extensive, up-to-date coverage of invertebrates, arthropods, vertebrates, fishes, amphibians and reptiles, birds, and mammals. In addition, the work features a detailed introduction by the author, as well as thorough subject, title, and author indexes. Students and researchers can now quickly and easily pinpoint works in their field of study. The book is of equal importance to LIS students specializing in science or biology librarianship, as it provides a comprehensive, straight-forward overview of zoological information sources. An essential addition to the core reference collection of public and academic libraries!

Download or read book Kinship with Monkeys written by Loretta A. Cormier and published by Columbia University Press. This book was released on 2003-10-15 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intrigued by a slide showing a woman breast-feeding a monkey, anthropologist Loretta A. Cormier spent fifteen months living among the Guajá, a foraging people in a remote area of Brazil. The result is this ethnographic study of the extraordinary relationship between the Guajá Indians and monkeys. While monkeys are a key food source for the Guajá, certain pet monkeys have a quasi-human status. Some infant monkeys are adopted and nurtured as human children while others are consumed in accordance with the "symbolic cannibalism" of their belief system. The apparent contradiction of this predator/protector relationship became the central theme of Cormier's research: How can monkeys be both eaten as food and nurtured as children? Her research reveals that monkeys play a vital role in Guajá society, ecology, economy, and religion. In Guajá animistic beliefs, all forms of plant and animal life—especially monkeys—have souls and are woven into a comprehensive kinship system. Therefore, all consumption can be considered a form of cannibalism. Cormier sets the stage for this enlightening study by examining the history of the Guajá and the ecological relationships between human and nonhuman primates in Amazonia. She also addresses the importance of monkeys in Guajá ecological adaptation as well as their role in the Guajá kinship system. Cormier then looks at animism and life classification among the Guajá and the role of pets, which provide a context for understanding "symbolic cannibalism" and how the Guajá relate to various forms of life in their natural and supernatural world. The book concludes with a discussion of the implications of ethnoprimatology beyond Amazonia, including Western perceptions of primates.

Download or read book The Pantanal of Mato Grosso (Brazil) written by F.D. Por and published by Springer Science & Business Media. This book was released on 1995-07-31 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now there has never been a monograph devoted to the Pantanal, the world's largest wetland. The subject has received scant attention in the international literature, so a number of scattered Portuguese papers are reviewed for an English-language readership. The book presents a broad treatment of the Pantanal, ranging from geology to flora, fauna, and the human presence. The publication of this book is most timely, and will be of crucial importance in decisions affecting the ambitious project for a second South American inland Waterway.

Download or read book Evolution in the Dark written by Horst Wilkens and published by Springer. This book was released on 2017-05-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides fascinating insights into the development and genetics of evolutionary processes on the basis of animals living in the dark, such as the Astyanax cave fish. Biologically functionless traits show high variability, which results from neutral deleterious mutations no longer being eliminated by natural selection, which normally acts to preserve functional capability. These negative mutations accumulate until the traits they are responsible for become rudimentary or even lost. The random genetic basis of regressive evolution is in accordance with Nei’s Neutral Theory of Molecular Evolution, which applies to the molecular level. Such processes are particularly conspicuous in species living in constant darkness, where, for example in Astyanax, all traits depending on the exposure to light, like eyes, pigmentation, visually triggered aggressive behaviour, negative phototaxis, and several peripheral outcomes of circadian rhythmicity, are useless and diminish. In compensation constructive traits like taste, olfaction or the lateral line senses are improved by selection and do not show variability. Regressive and constructive traits inherit independently, proving that the rudimentation process is not driven by pleiotropic linkage between them. All these traits are subject to mosaic evolution and exhibit unproportional epistatic gene effects, which play an important role in evolutionary adaptation and improvement. Offering valuable evolutionary insights and supplemented by a wealth of illustrations, this book will appeal to evolutionary and developmental biologists alike.
