This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in many cases, to include terrestrial species of orders that include both terrestrial and aquatic taxa. In no case is a taxonomic reVlSlon of any group undertaken, although recommendations for such revisions are included, and the probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches are employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Odonata and Ephemeroptera or the families Dytiscidae and Culicidae, keys are provided to distinguish all genera and species known to occur in South America. An effort has been made to include every identifiable species so that the user of the key can determine with reasonable certainty whether or not his specimen belongs to a species that has already been described or whether it is one that is not yet known to science.

Springtails are the most numerous and wide-spread insects in terrestrial ecosystems. They are important ecotoxicological test organisms and have been used extensively to indicate the effects of environmental pollutants and different agricultural regimes on biodiversity in soils. This comprehensive work by the co-author of The biology of millipedes is the only single-volume review of the biology of springtails in the English language to appear this century. The book covers classification, behaviour, physiology, evolution, ecology, and ecotoxicology. An extensive reference section with more than 2500 entries is included together with a complete list of all Collembola genera, a list of studies on the effects of chemicals on springtails, and reference to species checklists for most countries of the world.

This is the first part of a multivolume monograph dealing with the about 400 species of springtails (Collembola) which are known to occur in the Nordic countries, including the Arctic Islands. Volume 1 contains richly illustrated identification keys and full descriptions of 161 species of the section Poduromorpha. The geographical distribution and the preferred natural habitats of the species are summarised. New morphological concepts in species diagnostics are introduced, in particular concerning the mouthparts' morphology which greatly aids in precise identification of the many difficult species of the family Onychiuridae. The book will be indispensable to everyone working with springtail identification in northern Europe. The introduction of new diagnostic characters will be of universal interest to any Collembola taxonomist.

This volume completes the survey of the ca. 400 species of springtails, which can be found in Finland, Sweden, Norway, Denmark, Iceland, the Faroes and the Arctic Islands and includes the sections Entomobryomorpha and Symphypleona. The first volume, published in 1998, covered Poduromorpha. Identification keys and full descriptions of the species are richly illustrated by line drawings. Photos are provided for some species displaying characteristic patterns of pigmentation. New diagnostic characters, including sensillary chaetotaxy and details of the mouth apparatus, are introduced. With the appearence of this book soil scientists and the interested amateur have now a modern tool to identify all species of Nordic springtails. In addition the habitat preferences and geographical distribuition are summarised. The book will be of general interest to everyone working on springtail identification.

Mycorrhizal research has grown by leaps and bounds in the past few decades. These fungi promise to promote plant growth, maintain plant and soil health, assist in bio-protection against root diseases, encourage production with reduced fertilizer and pesticides, allow for nutrient acquisition, affect soil skeletal structure holding primary soil particles together, are conductive to the formation of microaggregate structures and higher rhizosphere populations, enable symbiosis that alters host water relations, as well as alter root length and architecture. These fungi also help with the re-vegetation of landscapes, golf courses or contaminated soils. They assist with the biological hardening of tissue culture raised plants, postpone leaf dehydration, draught responses, osmo-protecting enzymes and enhance P acquisition. AM symbiosis could conceivably affect any of these steps. AMF should be considered as an alternative to costly soil disinfection. The mechanisms by which fungi induce resistance in their hosts and enhance disease resistance need critical evaluation and examination. Editors see this volume as a tremendously valuable collection of specialized up-date chapters describing the most sophisticated and modern protocols in mycorrhizal research, thoroughly explained and synthesized.

In ecosystems with many species, food webs form highly complex networks of resource-consumer interactions. At the same time, the food web as itself needs sufficient resources to develop and survive. So in fact, food web ecology is about how natural resources form the basis of biological communities, in terms of species richness and abundances as well as how species are organised in communities on the basis of the resource availability and use. The central theme of this book is that patterns in the utilisation of energy result from the trophic interactions among species, and that these patterns form the basis of ecosystem stability. The authors integrate the latest work on community dynamics, ecosystem energetics, and stability, and in so doing attempt to dispel the categorisation of the field into the separate subdisciplines of population, community, and ecosystem ecology. Energetic Food Webs represents the first attempt to bridge the gap between the energetic and species approaches to ecology.
