Download or read book Insect Reproduction written by S. R. Leather and published by CRC Press. This book was released on 2018-01-18 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consisting of ten review chapters contributed by leading workers in their respective fields, from around the world, covers the whole subject of insect reproduction.It begins with the basic physiological questions of insect reproduction, moves on to discuss the new advances seen in the fields of behavioural and ecological mechanisms, and culminates by examining the recent work on evolutionary biology and its application in the field. Each chapter, although including a brief review of the basic seminal work, focuses mainly on the advances made within the last ten years and highlights those areas in which the respective authors see the greatest scope for further important advances
Download or read book The Lives of Lepidopterists written by Lee A. Dyer and published by Springer. This book was released on 2015-12-01 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inchworms, tiger moths, underwings, owlet moths, silkworms,sphinx moths, grass moths, and butterflies. Collectively, these and many others are the Lepidoptera, one of the most diverse groups of animals on the planet. Lepidoptera can be found in the highest tropical canopies,the driest deserts, and at the leading edge of science. The adults include some of the most beautiful insects that have inspired artists and have sailed through the dreams of human cultures for millennia. The immature stages (“caterpillars”), like the underwing depicted on the cover, link together vital processes in diverse terrestrial ecosystems that are only barely documented let alone understood. The people that study these animals are lepidopterists, and the goal of this book is to introduce them with their own words. In twenty chapters, lepidopterists tell their stories, and these tales mirror the diversity of nature in their range and depth. You will find individuals that wrestle with the challenges of scientific careers, stories of far flung travel sand close calls, and historical perspectives on recent decades of scientific break throughs.
Download or read book Metapopulation Dynamics Empirical and Theoretical Investigations written by Michael Gilpin and published by Academic Press. This book was released on 2012-12-02 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metapopulation Dynamics: Empirical and Theoretical Investigations covers the 1989 proceedings of a metapopulation dynamics workshop held at Lammi Biological Station, Helsinki, Finland. It is divided into 18 chapters that cover various approaches to spatially structured population and community dynamics. After briefly discussing the history of metapopulation ideas and the major conceptual links, the book covers types of studies that have been conducted on single-species and multispecies metapopulations. Then, it examines the relationships between metapopulation dynamics, the equilibrium theory of island biogeography, and the dynamics of populations living in patchy environments. It further tackles practical issues and the links between metapopulation dynamics and landscape ecology, and between metapopulation dynamics and conservation biology. Chapters 4 and 5 present structured models describing changes in the number of individuals within patches and an empirical evaluation of local extinction in metapopulation studies. The subsequent chapters discuss several aspects of metapopulation, including dispersal and connectivity, colonization, conspecific attraction, extinction and isolation, and forest fragmentation. The latter chapters describe the concept of habitat fragmentation, the diversity and competition in metapopulations, the community collapse, and the effects of metapopulation studies in predator-prey systems.

Download or read book Global Warming and Biological Diversity written by Robert L. Peters and published by Yale University Press. This book was released on 1992-01-01 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological effects of global warming should be of concern to all thinking individuals, for warming could cause profound disruption of natural ecosystems and could threaten many species with extinction. This important book--the first to discuss in detail the consequences of global warming for ecosystems--includes commentary by distinguished scientists on many aspects of this critical problem. Experts describe responses of animals and plants to previous climate changes, interactions between various environmental components (precipitation and soil chemistry, for example), and synergisms between climate change and human activities such as deforestation. They consider many specific ecosystems, including tropical forests, the deciduous forests of eastern North America, the forests of the Pacific Northwest, Mediterranean-type ecosystems in California, arctic tundra, and arctic marine systems. Offering discussions that are both factual and speculative, the volume points the way to future investigations of the implications of global warming.

Download or read book The Ecological Basis of Conservation written by Steward Pickett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: From its inception, the U.S. Department of the Interior has been charged with a conflicting mission. One set of statutes demands that the department must develop America's lands, that it get our trees, water, oil, and minerals out into the marketplace. Yet an opposing set of laws orders us to conserve these same resources, to preserve them for the long term and to consider the noncommodity values of our public landscape. That dichotomy, between rapid exploitation and long-term protection, demands what I see as the most significant policy departure of my tenure in office: the use of science-interdisciplinary science-as the primary basis for land management decisions. For more than a century, that has not been the case. Instead, we have managed this dichotomy by compartmentalizing the American landscape. Congress and my predecessors handled resource conflicts by drawing enclosures: "We'll create a national park here," they said, "and we'll put a wildlife refuge over there." Simple enough, as far as protection goes. And outside those protected areas, the message was equally simplistic: "Y'all come and get it. Have at it." The nature and the pace of the resource extraction was not at issue; if you could find it, it was yours.
