Download or read book The Evolution of Primary Sexual Characters in Animals written by Janet Leonard and published by Oxford University Press. This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.
Download or read book Spiders of Panama written by Nentwig and published by CRC Press. This book was released on 1993-01-01 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: in collaboration with Bruce Cutler and Stefan Heimer The available information, personal observations, and study of one facet of the beauties of the tropical rain forest of Panama is gathered into a much needed volume which includes the physical, biological, and spider environment of Panama. The complete list of known Panama spiders with literature references and a key to the families and most genera provides the user with an up-to-date guide to this fauna. With over 350 illustrations, numerous charts, graphs, and tables, the coverage of this volume goes far beyond the geographical boundary of the study, making it useful to all students of spiders.

Download or read book Integrated Pest Management written by Dharam P Abrol and published by Academic Press. This book was released on 2013-08-28 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated Pest Management: Current Concepts and Ecological Perspective presents an overview of alternative measures to traditional pest management practices using biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation — recognized as a suitable, long-term strategy — effectively suppresses pests in biotechnological control systems. Integrated Pest Management covers these topics and more. It explores the current ecological approaches in alternative solutions, such as biological control agents, parasites and predators, pathogenic microorganisms, pheromones and natural products as well as ecological approaches for managing invasive pests, rats, suppression of weeds, safety of pollinators, role of taxonomy and remote sensing in IPM and future projections of IPM. This book is a useful resource to entomologists, agronomists, horticulturists, and environmental scientists. - Fills a gap in the literature by providing critical analysis of different management strategies that have a bearing on agriculture, sustainability and environmental protection - Synthesizes research and practice on integrated pest management - Emphasizes an overview of management strategies, with critical evaluation of each in the larger context of ecologically based pest management

Dichos estudios intentan abordar los grupos de mayor interés. En el medio terrestre fueron objeto de investigación las plantas, algunos invertebrados, y todos los vertebrados. Pero por desgracia, hemos tenido que dejar para mejor ocasión los estudios marinos; la causa no fue otra que la carencia de las garantías mínimas de seguridad, al no disponer todavía en la zona de infraestructura adecuada para el equipo de buceo
