Book Description
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.

Book Description
We provide a current listing of the species of midges (Diptera:Chironomidae) in the southeastern United States (Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee). This checklist should aid in research on this group of insects, which have often proved useful in the assessment of water quality. We document each species distribution and general habitat and provide the best taxonomic reference to facilitate the identification or description of species in that genus. Changes in nomenclature, unique ecological traits, bibliographic sources, or other items of information are summarized in a paragraph on each genus. Regional distribution of the principal subfamilies indicated that the species of Chironominae and Tanypodinae were concentrated in the coastal region, whereas the Orthocladiinae were evenly distributed from the coast to the mountains. Considering the major habitats (lakes, rivers, and streams), Tanypodinae were about evenly distributed; Orthocladiinae were more predominant in streams and Chironominae in lakes.

Book Description
This illustrated introduction to Central American Chironomidae offers extensive photographic material, as well as detailed morphological and ecological descriptions of chironomid subfossils found in Central American lake sediments. The book uniquely provides two identification keys: one for living larvae occurring (or potentially being present) in Central America and one for the recorded subfossil remains, using limited morphological characters. Paleolimnological investigations using chironomid remains have undergone a resurgence of interest, and this taxonomic guide will aid the thorough analysis of the diversity and distribution of the taxa encountered to date in Central America. Out of the total 64 described genera, the book brings 20 endemic genera, and more than half of the presented morphotypes are new. Plates are included for each taxon with generic characters and also provide a key to morphotypes, if present, their specific characters, distribution, and ecology. Authored by a (paleo)limnologist and a taxonomist, the guide draws on a thorough taxonomical knowledge of the region’s recent chironomid fauna. It uses a paleolimnological approach to transmit this information to morphotypes that can be linked with ecology and used to reconstruct the past development of nature. The book thus helps paleo-workers and taxonomists to learn more about these fascinating insects and, through them, to discover the world around us. Providing a comprehensive reference for aquatic ecologists, paleolimnologists, students, and researchers, the guide will also be of interest to non-academic professionals working on applied research and biomonitoring of lakes. It will be useful for people studying both recent and subfossil material, not only in Central America, but in the whole Neotropical region.
