Download or read book The Chironomidae written by P.D. Armitage and published by Springer Science & Business Media. This book was released on 1994-12-31 with total page 606 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 Chironomids written by P. S. Cranston and published by CSIRO Publishing. This book was released on 1994 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Paleolimnology written by Andrew S. Cohen and published by Oxford University Press. This book was released on 2003-05-29 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
Download or read book Beneficial Microorganisms in Multicellular Life Forms written by Eugene Rosenberg and published by Springer Science & Business Media. This book was released on 2011-08-30 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: All animals and plants form associations with hundreds or thousands of different beneficial microorganisms. These symbiotic microbes play an important role in the development, adaptation, health and evolution of their hosts. This book brings together a group of diverse biologists to discuss microbial interactions with multicellular life forms including insects, corals, plants, and mammals, including humans. The various mechanisms by which microorganisms benefit their hosts are discussed, including providing essential nutrients, preventing disease, inducing the immune system, and combating stress. Since the microbiota can be transferred from parent to offspring, it plays an important role in the origin and evolution of animal and plant species. This book should be of interest to the widest range of biological scientists, merging the studies of host and microbial physiology, symbiosis, and the ecology and evolution of symbiotic partners.

Download or read book The Use of Morphological Deformities in Chironomid Larvae for Biological Effects Monitoring written by William Frank Warwick and published by Saskatoon : Inland Waters Directorate, National Hydrology Research Institute, National Hydrology Research Centre. This book was released on 1990 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological communities provide a direct means of observing the impact of contaminants because they are exposed to, and directly involved in, the transformations that contaminants undergo in freshwater ecosystems. The response of these communities provides a direct measure of the net toxic burden impacting an ecosystem. The purpose of this paper is to review the role of chironomids (Diptera: Chironomidae) in aquatic communities and, in particular, the utility of morphological deformities in chironomid larvae for detecting and assessing the significance of contaminants in freshwater ecosystems.
Download or read book Palaeolimnological Proxies as Tools of Environmental Reconstruction in Fresh Water written by Krisztina Buczkó and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeolimnology is one of the most rapidly developing fields of limnology. The primary objective of this volume is to present new palaeolimnological findings from eastern and central Europe. Although this area has sometimes received less attention than other areas of Europe, the lakes and mires, coupled with the variability in landscape and the local differences in climate, provide unique opportunity for studying palaeolimnology. The volume starts with a review on late Quaternary records form the Carpathian region, followed by new results on the history of a crater lake, Lake Saint Ana, glacial lakes in the Tatra Mountains and Lake Bled in Slovenia. In addition, the various papers provide new insights on the development of lakes and bogs during the late glacial and Holocene, using a wide range of palaeolimnological proxies, including diatoms, pollen, macrofossils, pigments, cladoceran remains, chironomids, chaoborids, stable isotopes and geochemistry. The motivation for collecting recent knowledge derives from the recognition of the importance, and applicability of palaeolimnological tools to help in defining "reference conditions" as designated within the Water Framework Directives and estimating influence of global climate change on surface waters.
Download or read book The Biology of Freshwater Wetlands written by Arnold G. van der Valk and published by OUP Oxford. This book was released on 2012-02-09 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global wetlands exhibit significant differences in both hydrology and species composition and range from moss-dominated arctic peatlands to seasonally-flooded tropical floodplains. They are increasingly recognized for the important services that they provide to both the environment and human society such as wildlife and fish production, nutrient filtering, and carbon sequestration. A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological features of wetland habitats, with an emphasis on wetland plants and animals and their adaptations. It also describes the functional features of wetlands - primary production, litter decomposition, food webs, and nutrient cycling - and their significance locally and globally. The future of wetlands is examined, including the potential threats of global climate change and invasive species, as well as their restoration and creation. This new edition maintains the structure and style of the first, but is fully updated throughout with new chapters on invasive species, restoration/creation, global climate change, and the value of wetlands.
