Download or read book Biodiversity Conservation and Phylogenetic Systematics written by Roseli Pellens and published by Springer. This book was released on 2016-02-24 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.
Download or read book Caatinga written by José Maria Cardoso da Silva and published by Springer. This book was released on 2018-01-09 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides in-depth information on Caatinga’s geographical boundaries and ecological systems, including plants, insects, fishes, amphibians, reptiles, birds, and mammals. It also discusses the major threats to the region’s socio-ecological systems and includes chapters on climate change and fast and large-scale land-use changes, as well as slow and small-scale changes, also known as chronic human disturbances. Subsequent chapters address sustainable agriculture, conservation systems, and sustainable development. Lastly, the book proposes 10 major actions that could enable the transformation of Caatinga into a place where people and nature can thrive together. “I consider this book an excellent example of how scientists worldwide can mobilize their efforts to propose sound solutions for one of the biggest challenges of modern times, i.e., how to protect the world’s natural ecosystems while improving human well-being. I am sure this book will inspire more research and conservation action in the region and perhaps encourage other groups of scientists to produce similar syntheses about their regions.” Russell Mittermeier, Ph.D. Executive Vice-Chair, Conservation International

This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean-type ecosystems have provided ecologists with some of the most scientifically-rewarding opportunities to formulate and evaluate hypotheses about large and small-scale ecological phenomena. Comparison of mediterranean-type climate ecosystems in different parts of the world has not only permitted a strong test for ecological convergence, but also critical understanding of key ecophysiological and population processes.
Download or read book Vertebrate Sound Production and Acoustic Communication written by Roderick A. Suthers and published by Springer. This book was released on 2016-04-27 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the fundamental principles of vocal production are well-understood, and are being increasingly applied by specialists to specific animal taxa, they stem originally from engineering research on the human voice. These origins create a double barrier to entry for biologists interested in understanding acoustic communication in their study species. The proposed volume aims to fill this gap, providing easy-to-understand overviews of the various relevant theories and techniques, and showing how these principles can be implemented in the study of all main vertebrate groups. The volume will have eleven chapters assembled from the world's leading researchers, at a level intelligible to a wide audience of biologists with no background in engineering or human voice science. Some will cover sound production in a particular vertebrate group; others will address a particular issue, such as vocal learning, across vertebrate taxa. The book will highlight what is known and how to implement useful techniques and methodologies, but will also summarize current gaps in the knowledge. It will serve both as a tutorial introduction for newcomers and a springboard for further research for all scientists interested in understanding animal acoustic signals.

This book was released on 2006-12-11 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compendium of the latest research on acoustic communication in these highly vocal vertebrates. The chapters are written by experts currently investigating the physiology and behavior of amphibians, in the laboratory and in the field. This integrated approach provides a neuroethologically-driven and evolutionary basis for our understanding of acoustic communication and its underlying mechanisms. The intended audience includes senior undergraduates, physiologists, zoologists, evolutionary biologists and communication specialists.

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 2015-04-01 with total page 750 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 Niño events to prognoses for the future environments of the continent.

Download or read book The Tungara Frog written by Michael J. Ryan and published by University of Chicago Press. This book was released on 1985 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a Panamanian pond, male túngara frogs (Physalaemus pustulosus) gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Túngara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the túngara frog's calls.
