Book Synopsis Grassland Invertebrates by : Jim P. Curry
Download or read book Grassland Invertebrates written by Jim P. Curry and published by Springer Science & Business Media. This book was released on 1993-11-30 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasslands comprise more than a quarter of the Earth's land surface. In addition to supporting a wide range of vertebrates such as domestic livestock and a variety of games species, grassland is the natural habitat for a wide range of invertebrate species, and this book considers those which occur in grassland and their impact on soil fertility and herbage growth. It describes grassland as a habitat for invertebrates, the groups which occur there and their abudance. An extensive literature on grassland invertebrates scattered through numerous scientific journals and reports is drawn on in an attempt to develop an overview. In the opening chapter the major grassland types are considered and the features which influence the distribution and abudance of the invertebrates which inhabit them are discussed. Next the major taxonomic groups are reviewed in turn, with a brief account of their biology and ecology and of their ecosystem role. Some general features of grassland invertebrate communities are then described and teh factors which influence th epopulation densities of their constituent species are considered. Particular attentionm is given to the ways in which populations are influenced by management practices. The final and largest chapterdeals with the various ways in which invertebrates influence important grassland processes through ingestion of organic matter, interaction with injurious species is considered, with particular emphasis on the potential for achieving this through manipulating grassland management practices.

Download or read book The Chironomidae written by P.D. Armitage and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.
