Download or read book Molluscs as Crop Pests written by G. M. Barker and published by CABI. This book was released on 2002-03-21 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

Download or read book Modern Nature written by Lynn K. Nyhart and published by University of Chicago Press. This book was released on 2009-08-01 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Modern Nature,Lynn K. Nyhart traces the emergence of a “biological perspective” in late nineteenth-century Germany that emphasized the dynamic relationships among organisms, and between organisms and their environment. Examining this approach to nature in light of Germany’s fraught urbanization and industrialization, as well the opportunities presented by new and reforming institutions, she argues that rapid social change drew attention to the role of social relationships and physical environments in rendering a society—and nature—whole, functional, and healthy. This quintessentially modern view of nature, Nyhart shows, stood in stark contrast to the standard naturalist’s orientation toward classification. While this new biological perspective would eventually grow into the academic discipline of ecology, Modern Nature locates its roots outside the universities, in a vibrant realm of populist natural history inhabited by taxidermists and zookeepers, schoolteachers and museum reformers, amateur enthusiasts and nature protectionists. Probing the populist beginnings of animal ecology in Germany, Nyhart unites the history of popular natural history with that of elite science in a new way. In doing so, she brings to light a major orientation in late nineteenth-century biology that has long been eclipsed by Darwinism.

Download or read book Spitsbergen Push Moraines written by J.J.M. van der Meer and published by Elsevier. This book was released on 2004-04-20 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with push moraines on Spitsbergen. The main body is a translation of the original German report by Karl Gripp on a 1927 expedition. The quality of Gripp's work is evaluated to see whether it stands the test of time. It is found that it is very modern, every year people still go into the field with the same research questions. It is also found that most likely Gripp's report contains the first description of features that we now take for granted, for instance the description of looped moraines to detect surges. Push moraines are still being studied and to show where we stand now two papers have been added that analyse two particular examples, Holmströmbreen and Sefströmbreen. The two examples are geographically close together, but reflect two completely different settings: terrestrial Holmströmbreen and tidewater Sefströmbreen. Since a few years we know of the De Geer Archive, a collection of glass negatives of Spitsbergen, relating to De Geer's expeditions between 1882 and 1910. The negatives have only emerged recently and a collection of prints relating to Holmströmbreen and Sefströmbreen is included here. Together with a third paper incorporated in the book, this time an evaluation of De Geer's photos and maps of the Sefströmbreen surge, this material shows the importance of incorporating historical documentation in our studies.

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.
