The Chironomidae popularly are called "non-biting midges" to distinguish them from their biting relatives. Although the impact of these flies excludes human-feeding and disease transmission, chironomids are still the subject of much study. This book presents current research on topics such as the use of chironomid larvae in pollution monitoring; austral chironomid patterns; biology and control; chironomid communities and auto-ecology; morphology and systematics of chironomids. The value of chironomids and other aquatic biota in the monitoring of waterway health is emphasised with reviews from both the northern and southern hemispheres.

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.

Chironomidae Larvae of the Netherlands and Adjacent Lowlands Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. The subfamily Orthocladiinae is well represented in flowing water. This books contains information about their life cycle, feeding behaviour and their response to environmental factors. Chironomidae Larvae, Vol. 3: Orthocladiinae presents a wealth of information for scientific and practical purpose. The subfamily Orthocladiinae is especially well represented in flowing water. Most of the species need a good supply of oxygen and few larvae are bottom dwellers. Many species emerge early in spring and may be scarce in summer. Other species live in stagnant and even temporary water bodies. • information about the life cycle and feeding behaviour of the larvae and their response to environmental factors such as oxygen conditions, current velocity and saprobity • special attention to the interrelations between these factors • general and specific aspects of the systematics, biology and ecology the genera and species • nomenclature and identification An invaluable tool for aquatic ecologists and water quality management.

Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. The authors revised existing identification keys and collected additional information on the biology and ecology of the larvae. Where possible, the identification keys use anatomical characters that are easily observed. An invaluable tool for aquatic ecologists and water quality management.

Ecological Informatics is defined as the design and application of computational techniques for ecological analysis, synthesis, forecasting and management. The book provides an introduction to the scope, concepts and techniques of this newly emerging discipline. It illustrates numerous applications of Ecological Informatics for stream systems, river systems, freshwater lakes and marine systems as well as image recognition at micro and macro scale. Case studies focus on applications of artificial neural networks, genetic algorithms, fuzzy logic and adaptive agents to current ecological management issues such as toxic algal blooms, eutrophication, habitat degradation, conservation of biodiversity and sustainable fishery.

Research in ecotoxicology has accumulated a large body of information concerning the impact of chemical stress on life history of several model species. In contrast, potential effects of pollutants on intraspecific (genetic) variation in populations have rarely been investigated. This survey assesses the effects of heavy metal exposure on laboratory and field populations of the midge, Chironomus riparius (Chironomidae: Diptera). Six different studies are presented in this book, including the development of genetic markers for Chironomus midges, a quantification of genetic erosion in TBT-exposed Chironomus populations in the laboratory, and an investigation of genetic population structure of two Chironomus species in the field. These topics as well as the documentation of severe genetic impoverishment in laboratory populations of C. riparius and its effects on the outcome of toxicity tests will be of great interest to ecotoxicologists and experimental ecologists.
