Download or read book Sexual Segregation in Vertebrates written by Kathreen Ruckstuhl and published by Cambridge University Press. This book was released on 2006-01-05 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

Download or read book The Ecology Exploitation and Conservation of River Turtles written by Don Moll and published by Oxford University Press. This book was released on 2004-04-08 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The underlying theme of this book is that a widespread, taxonomically diverse group of animals, important both from ecological and human resource perspectives, remains poorly understood and in delcine, while receiving scant attention from the ecological and conservation community. This volume proposes a comprehensive overview of the world's river turtles' ecology, conservation, and management. It begins with a categorization of taxa which inhabit flowing water habitats followed by information on their evolutionary and physical diversity and biogeography. Within the framework of ecology, the authors discuss the composition of river turtle communities in different types of lotic habitats and regions, population dynamics, movements, reproductive characteristics and behavior, predators, and feeding relationships. In a conservation and management section, the authors identify and evaluate the nature and intensity of factors which threaten river turtle survival--almost all of which involve direct human exploitation or indirect effects of human induced habitat alteration and degradation. They then list and evaluate the various schemes which have been proposed or employed to halt declines and restore populations, and make recommendations for future management plans for specific species and regions. In closing, they state their viewpoint concerning future research directions and priorities, and an evaluation of future prospects for survival of the world's river turtle species.

Download or read book Hunting for Sustainability in Tropical Forests written by John Robinson and published by Columbia University Press. This book was released on 2000-02-08 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world people are concerned about the demise of tropical forests and their wildlife. Hunting by forest-dwelling people has a dramatic effect on wildlife in many tropical forests, frequently driving species to local extinction, with devastating implications for other species and the health of the forests themselves. But wildlife is an important source of protein and cash for rural peoples. Can hunting be managed to conserve biological communities while meeting human needs? Are hunting rates as practiced by tropical forest peoples sustainable? If not, what are the biological, social, and cultural implications of this failure? Answering these questions is ever more important as national and international agencies seek to integrate the development of local peoples with the conservation of tropical forest systems and species. This book presents a wide array of studies that examine the sustainability of hunting as practiced by rural peoples. Comprising work by both biological and social scientists, Hunting for Sustainability in Tropical Forests provides a balanced viewpoint on the ecological and human aspects of this hunting. The first section examines the effects of hunting on wildlife in tropical forests throughout the world. The next section looks at the importance of hunting to local communities. The third section looks at institutional challenges of resource management, while the fourth draws on economic perspectives to understand both hunting and sustainability. A final section provides synthesis and summary of the factors that influence sustainability and the implications for management. Drawing on examples from Ecuador to Congo-Zaire to Sulawesi, Hunting for Sustainability in Tropical Forests will be a valuable resource to policymakers, conservation organizations, and students and scholars of biology, ecology, and anthropology.

Download or read book Unsteady Transonic Flow written by Mårten T. Landahl and published by Courier Dover Publications. This book was released on 2019-04-17 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic monograph on unsteady transonic flow — the flow of air encountered at speeds at or near the speed of sound — is of continuing interest to students and professionals in aerodynamics, fluid dynamics, and other areas of applied mathematics. After a brief Introduction, Swedish physicist Mårten T. Landahl presents a chapter in which the two-dimensional solution is derived, succeeded by a discussion of its relation to the subsonic and supersonic solutions. Three chapters on low aspect ratio configurations follow, covering triangular wings and similar planforms with curved leading edges, rectangular wings, and cropped delta wings, and low aspect ratio wing-body combinations. The treatment concludes with a consideration of the experimental determination of air forces on oscillating wings at transonic speeds.

Download or read book Masters Theses in the Pure and Applied Sciences written by W. H. Shafer and published by Springer. This book was released on 1982-02-01 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing. house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
