Available in PDF, EPUB and Kindle. Book excerpt: Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. This book is an invaluable tool for aquatic ecologists and water quality management covering the most important tribes Chironomini and Pseudochironomini. It presents a wealth of information for professionals for scientific and practical purpose. The Chironomini larvae are the well-known red bloodworms. They are the most important group of the Chironomidae family in stagnant water and can be very numerous, especially in polluted water. Many species are detritus feeders and play a part in the decomposition of organic material. Most species live in a tube of small particles, attached to the substrate. The author has brought together a wealth of information on the biology and ecology of this group geared especially to water quality assessment. This collected knowledge is required in the interpretation of macro-invertebrate samples. An introduction gives background information on the influence of environmental factors on chironomid larvae. A unique focus on this ecologically important group, useful for professionals and especially important for its potential use in water quality management.

Available in PDF, EPUB and Kindle. Book excerpt: General ecology of the Chironomids and identification key to the Tanypodinae To most people midges are a nuisance—annoying creatures that can spoil a quiet evening. However, there are those who study these tiny insects with great passion, including the two authors of this book. Because the European Water Framework Directive requires the authorities to ascertain the presence status of macro-invertebrates in surface waters, their work gained more attention. Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. A major subfamily of this group are the Tanypodinae. The larvae of most of the species are free-swimming or crawling predators while those of other species burrow in the mud on the bottom. Since they inhabit a variety of habitats they can be found in almost all surface waters in the Netherlands. 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. The clear descriptions of the development stages, sampling methods and abiotic environmental factors help make this book useful for all students of chironomid larvae, professional or otherwise. This book is especially important for its potential use in water quality management.

Download or read book Chironomidae of Central America written by Ladislav Hamerlik and published by CRC Press. This book was released on 2020-11-26 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Algal species and in particular desmids are important indicators of water quality. Because of their preferential occurrence in vulnerable habitats, desmids lend themselves well to figuring in conservation studies. The present flora describes all desmid taxa known from the Netherlands and adjacent lowland areas: over 500 species and more than 150 additional varieties. Because of the predominantly cosmopolitan nature of most species the flora may also be of use outside this geographic region. The enclosed CD-ROM offers general information on desmid biology as well as a selection of species that are discussed in more detail. Ecological data, both on separate species and desmid communities, enable a characterization of the habitat sampled.

Download or read book Plitvice Lakes written by Marko Miliša and published by Springer Nature. This book was released on 2023-03-19 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: After providing a historical overview, this book highlights the current state of knowledge, gaps in our knowledge, recent findings and future prospects with regard to the biological, chemical, geological, and geographical specificities of the Plitvice lakes in Croatia. The Plitvice lakes are a unique environment and home to tufa – a type of calcium carbonate deposit that provides a substrate for living organisms. Its formation process has resulted in a vastly diverse environment of lakes, streams and riparian habitats. The Plitvice lakes have, therefore, historically been both an inspiration and a challenge for scientists, nature enthusiasts, artists, etc. Today, the lakes continue to offer an in-situ laboratory for new discoveries in all aspects of freshwater science. As in most habitats, global changes have become an important issue. Since the Plitvice lakes have remained largely untouched by direct human impacts and have a long historical tradition in research, they represent an ideal subject for assessing the effects of global changes in a temperate freshwater system. This book provides an ecological overview of the biogeochemical processes at work in a unique and virtually pristine European freshwater tufa-forming environment.

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.

Download or read book Ecology and Biogeography of High Altitude Insects written by M.S. Mani and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas.

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
