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 The Mayflies of Europe Ephemeroptera written by Ernst Bauernfeind and published by BRILL. This book was released on 2013-01-21 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the various groups of aquatic insects, mayflies (Ephemeroptera) are of special interest for professional limnologists and entomological researchers as well as for naturalists in general and even the dedicated fly angler. Identification has traditionally been considered difficult and implementation in environmental monitoring and freshwater management has led to an ever increasing demand for exact information on taxonomy and ecology. The present handbook is designed to provide for the first time an up-to-date standard work for Ephemeroptera identification, including last instar larvae (nymphs), subimago (dun), male and female imagines. Recent changes in nomenclature are discussed in detail as well as gaps in current knowledge and probable pitfalls concerning the reliable identification of all taxa known so far from the region. Keys are provided for genera and introductory chapters characterize every family and genus. Species accounts follow a common format providing a synonymy, characters for identification (including literature references), remarks (on type material, variation, confusing or extralimital species) and short information on biology and distribution pattern. Male genitalia are illustrated by micrographs and line drawings, REM photographs of the egg chorionic structure are provided for genera and selected species. Habitus of larvae and imagines are for most genera illustrated by colour photographs. The geographical area covered is Europe including the European part of Russia, the mediterranean islands and North Africa. Short additional information is provided for adjacent parts of the western Palaearctic Region. A comprehensive index, check-list and distribution catalogue (following the widely adopted concept of Illies’ Limnofauna Europaean) allow for quick information on all species recorded so far from Europe.

Download or read book The Biology of Caves and Other Subterranean Habitats written by David C. Culver and published by Oxford University Press. This book was released on 2019-04-01 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this widely cited textbook continues to provide a concise but comprehensive introduction to cave and subterranean biology, describing this fascinating habitat and its biodiversity. It covers a range of biological processes including ecosystem function, evolution and adaptation, community ecology, biogeography, and conservation. The authors draw on a global range of examples and case studies from both caves and non-cave subterranean habitats. One of the barriers to the study of subterranean biology has been the extraordinarily large number of specialized terms used by researchers; the authors explain these terms clearly and minimize the number that they use. This new edition retains the same 10 chapter structure of the original, but the content has been thoroughly revised and updated throughout to reflect the huge increase in publications concerning subterranean biology over the last decade.

Download or read book Streams and Ground Waters written by Jeremy B. Jones and published by Elsevier. This book was released on 1999-12-06 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Streams around the world flow toward the sea in floodplains. All along this transit, there is exchange of water between the stream itself and the surrounding sediments which form the floodplain. Many chemical, biological, and geological processes occur when water moves back and forth between streams and these flood plain sediments. Streams and Groundwaters focuses on the consequences of water flow between streams, their underlying sediments, and surrounding landscapes. Certain to appeal to anyone interested in stream ecology, the management of stream ecosystems, or landscape ecology, this volume should become a oft-opened reference.

Download or read book Encyclopedia of South American Aquatic Insects Ephemeroptera written by Charles W. Heckman and published by Springer Science & Business Media. This book was released on 2002-08-31 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 some cases, to include terrestrial species of orders comprising both terrestrial and aquatic taxa. In no case is a taxonomic revision of any group undertaken, although recommendations for such revisions are included where appropriate, and probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches will be employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Plecoptera 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 ofthe 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. Where feasible, complete keys will be prepared for groups containing both aquatic and terrestrial species that do not encompass an extraordinarily large number ofspecies. This has already been done for the order Collembola.

Download or read book Hydraenidae Coleoptera written by Michael Hansen and published by BRILL. This book was released on 2023-08-14 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. We are therefore proud to launch this major series. Volumes will as a minimum contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e. g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume one focuses on Hydraenidae (Coleoptera).

This book was released on 2013-03-09 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.

Download or read book Physiology of the Cladocera written by Nikolai N. Smirnov and published by Academic Press. This book was released on 2017-06-01 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiology of the Cladocera, Second Edition, is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable review is based on the world’s literature, including Russian research not previously widely available, and offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution. It features the addition of new sections and a vast amount of new information, such as the latest data on feeding, nutrition, pathological physiology, chemical composition, neurosecretion, and behavior, as well as hormonal regulation, antioxidants, and the biochemical background of effects of natural and anthropogenic factors. Additional expertly updated contributions in genetics and cytology, and a new chapter in embryology, round out the physiological chapters, and provide comprehensive insight into the state of knowledge of Cladocera and their underlying mechanisms. Cladocera crustaceans have become globally studied for many purposes, including genetic, molecular, ecological, environmental, water quality, systematics, and evolutionary biology research. Since the genome of Daphnia was sequenced and published, that system has gained much wider exposure, also leading to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics as well as ecogenomic toxicology. However, the physiological background on Cladocera has been fragmentary (including on the other 700 known species besides Daphnia), despite the extensive literature on species identification and morphology. This work addresses this issue by collecting and synthesizing from the literature the state of knowledge of cladoceran physiology, including discussion on both adequately and inadequately investigated fields, and thus directions of future research. Summarizes fundamental information obtained in recent years, including on steroids, antioxidants, hormones, nanoparticles, and impact of wastewater of pharmaceutical industries Provides the foundational information needed for scientists and practitioners from a variety of fields, including conservation and evolutionary biology, genomics, ecology, ecotoxicology, comparative physiology, limnology, zoology–carcinology, and water quality assessment Features coverage of both Daphniids and representatives of other families, with attention drawn to little-studied aspects of their physiology, especially of those living in the litt oral zone Includes guidance to the literature on cladoceran physiology in four languages Discusses advantages and shortcomings of Cladocera as experimental animals and indicators of water quality

Download or read book Fasciolosis 2nd Edition written by John P. Dalton and published by CABI. This book was released on 2021-12-14 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fasciolosis is a major global infection of livestock causing both huge losses to the agricultural community and affecting human health as a food-borne disease. Fully updated throughout, this new edition continues to cover the life cycle, biology, and development of the parasite; clinical pathology, immunology, diagnosis and vaccine development; and emergence, cause and mechanisms of drug resistance. It reviews the temperate liver fluke Fasciola hepatica, together with molecular, biochemical, control, and epidemiologial aspects of the tropical liver fluke F. gigantica. Many fundamental advances have taken place in the last two decades, but of particular importance has been the mapping of the draft genome of Fasciola. In addition, comprehensive advances in transcriptomics, proteomics and glycomics have been made, and the book therefore pays particular attention to these developments with the addition of brand-new chapters. Also covering the impact these parasites have had on the global human population, their distribution and their ecology, this book provides a comprehensive and accessible resource for scientists, researchers and students of medical and veterinary parasitology.
