View Rights PortalThere are over 40 000 named species of mite, and if estimates for unnamed species are included, then up to 1 million may grace the planet. By comparison, there are approximately 40 000 species of vertebrates, half of them fish, alive today. Mites are predators, parasites, herbivores and detritivores. They live in the dark depths of the ocean, in the lungs of birds, on the leaves of rainforest plants, and in human clothes and bedding. They are vectors of disease, vital players in soil formation, and important agents of biological control. Despite the grand diversity of mites, these small arthropods are often overlooked, and even trained biologists can be unaware of their significance.This books aims to fill the gap in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites, without requiring prior knowledge of their morphology or taxonomy. The text is richly illustrated with line drawings and photographs. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, and mites as models of ecological and evolutionary theories.
A major concern for biological control has always been the risk of indirect unwanted effects on the ecology of other organisms. Our understanding of the ecological and evolutionary processes underlying these effects has until now been limited and experimental methods sometimes lacking. This book presents the key papers from of the first International Organisation for Biological Control global symposium, held in Montpellier, France, in October 1999. It addresses the issues and concerns involved in biological control, and assesses the current status of evaluation of the ecological effects.
This books provides a comprehensive overview of grassland nitrogen incorporating information from crop science, soils and fertilizers, ruminant consumption and environmental aspects.The published information is reviewed on the various transformations of nitrogen in temperate grassland systems. These include those taking place in soils. The effects of soil, weather and management practices are discussed and considerable emphasis is placed on soil-plant-animal interactions. A second aim of the book is to describe the factors that influence the response of grassland to the application of fertilizer nitrogen, and how the optimum rate of application may be determined. In addition, nitrogen balances are described for different grassland systems, showing how the annual inputs and outputs vary greatly depending on sward type and management.The book is of interest to a wide readership, especially those engaged in research, teaching and advisory work, and students taking courses in agricultural and environmental sciences.
This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.
Forests are an important component in the visual appeal of landscapes. There is an increasing recognition of the importance of this subject among foresters and environmental scientists. Increasingly, forest resource managers must consider both the aesthetic consequences of timber harvesting operations and management plans and public perceptions of the sustainability of forest eco-system management.Written by world class authorities this book is the first to address this subject area. It consists of 17 chapters and is divided into six parts. The interdisciplinary nature of the book brings together not only foresters and ecologists, but also landscape architects, psychologists and philosophers. Contributors are leading research workers in their subjects, from Canada, the USA and UK.
The purpose of this book is to review and assess our current understanding of invertebrates in terrestrial and terrestrially-dominated (i.e. lower-order stream) ecosystems. It emphasises the centrality of the activity of invertebrates, which influence ecosystem function far out of proportion to their physical mass in a wide range of situations, particularly at the interface between land and air (litter/soil), water and land (sediments) and in tree canopies and root/soil systems. Consisting of 16 chapters by authors from the USA, Canada, Europe and Australia, the book is essential reading for ecologists and invertebrate biologists.
