Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Greenland Entomofauna written by Jens Böcher and published by BRILL. This book was released on 2015-05-26 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

Available in PDF, EPUB and Kindle. Book excerpt: High-Arctic Ecosystem Dynamics in a Changing Climate is based on data collected during the past 10 years by Zackenberg Ecological Research Operations (ZERO) at Zackenberg Research Station in Northeast Greenland. This volume covers the function of Arctic ecosystems based on the most comprehensive long-term data set in the world from a well-defined Arctic ecosystem. Editors offer a comprehensive and authoritative analysis of how climate variability is influencing an Arctic ecosystem and how the Arctic ecosystems have inherent feedback mechanisms interacting with climate variability or change. - The latest research on the functioning of Arctic ecosystems - Supplements current books on arctic climate impact assessment as a case study for ecological specialists - Discusses the complex perpetuating effects on Earth - Vital information on modeling ecosystem responses to understand future climates

Available in PDF, EPUB and Kindle. Book excerpt: In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."

Download or read book Body Size The Structure and Function of Aquatic Ecosystems written by Alan G. Hildrew and published by Cambridge University Press. This book was released on 2007-07-12 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Download or read book A Guide to the Identification of Genera of Chironomid Pupal Exuviae Occurring in Britain and Ireland including Common Genera from Northern Europe and Their Use in Monitoring Lotic and Lentic Fresh Waters written by Ronald S. Wilson and published by . This book was released on 2005 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 600 species of non-biting or "dancing" midges occur in Britain and Ireland, with many more on the continent of Europe. They are most noticeable when the adults perform mating flights in swarms along the shores of runningwater (lentic) and standing or still-water (lotic) habitats. The aquatic life-cycle of eggs, larvae and pupae usually lasts for a year or less. When adult midges emerge from their pupae the empty cast skins or pupal exuviae float on the water-surface and become part of the flotsam accumulating along strand-lines and in backwaters. In such places, pupal exuviae can be scooped-up easily with a long-handled pondnet, for subsequent identification under low magnification. This guide provides a series of multiple-choice keys for identifying the pupal exuviae of 145 genera and more than 100 selected species of Chironomidae that have been recorded from Britain and Ireland, including some that may become added to the list as they colonise the region from Northern Europe. The guide provides a simplified introduction to the complex taxonomy of the Family Chironomidae, and is intended for use by those who are not familiar with the group. The text is generously illustrated with line-drawings of important characters used for identification. An illustrated key is also given to separate the pupal exuviae of chironomids from the cast skins of other common aquatic insects that are similar in general appearance. All genera and species covered by the guide are allocated to one of four groups representing varying degrees of organic pollution, based on published knowledge of the ecological requirements of genera and individual species, and the authors' own extensive experience. Drs Wilson and Ruse use their Chironomid Pupal Exuvial Technique (CPET) to evaluate habitat diversity and the ecological quality of a wide variety of water-bodies, and to monitor any changes occurring in them. Their technique is comparable to others that are commonly employed in biological monitoring and assessment of water quality. CPET is summarised and briefly discussed in a special section of the text.
