Book Biology of Shore Flies

Download or read book Biology of Shore Flies written by B. A. Foote and published by . This book was released on 1995 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information is given on the habitat distribution, larval feeding habits and economic roles of the dipterous family Ephydridae. This family has broad ecological tolerances and is commonly encountered in such physiologically stressful habitats as oil pools, inland alkaline and saline marshes, hot springs and cold thermal springs, and coastal salt marshes and mangrove swamps. Other ephydrid species occur in freshwater marshes, moist to xeric grasslands, muddy and sandy shores, and rocky substrates along streams and lakes. Larvae display adaptive radiation in their use of particulate food stustrates, with different groups of species feeding on Cyanobacteria (blue-green algae), algae, detritus and decomposing carcasses. A few species are predators, whereas otehrs are leaf miners. Economically, certain species are pests in greenhouses and others damage crops such as rice and sugar beets. Other species are being investigated as agents of biological control of aquatic weeds. -- Abstract.

  • Release : 1976
  • ISBN :
  • Pages : 606 pages

Download or read book Marine Insects written by Lanna Cheng and published by North-Holland. This book was released on 1976 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.

Book Comparative Studies of the Population Ecology and Life History Patterns of an Alkaline Salt Lake Insect

Download or read book Comparative Studies of the Population Ecology and Life History Patterns of an Alkaline Salt Lake Insect written by David B. Herbst and published by . This book was released on 1986 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonal abundance and life history traits were compared between populations of the brine fly Ephydra (Hydrokyrus) hians Say (Diptera:Ephydridae), from two western Great Basin alkaline salt lakes. Abert Lake, Oregon, has a relatively low salinity (20-30 g/1 total dissolved solids) and more co-inhabitant benthic species than the higher salinity Mono Lake, California (75-90 g/l). During a period of declining salinities at both lakes, the abundance of this osmoregulating insect decreased at Abert Lake, and increased at Mono Lake. This suggests that abundance may be maximized at intermediate salinities due to biotic limitations imposed by competing and predatory species at dilute salinities, and physiological limitations imposed by osmotic stress at high salinities. Experimental rearing of larvae at high salinities, or reduced algal food supply levels, produced low survival, prolonged development, and smaller size at maturity. When food is not limiting, Mono Lake larvae exhibit greater independence of the inhibitory effects of increased salt concentration compared to larvae from less saline Abert Lake. Selection for enhanced salt tolerance may thus have occurred at Mono Lake, but appears to be limited above 150 g/1 because survival of first instars, and maturation of final instars are impaired at 200 g/l. Besides direct physiological effects, increased salinity also reduces algal growth and may thereby limit food availability to E. hians. Heritable differences in body size exist between populations in addition to environmentally induced changes in growth and size. Abert flies are inherently larger than Mono flies, and develop more rapidly at comparable salinity. Reduction in pupal size severely curtails emergence, and any small-bodied adults that do emerge possess only slight lipid stores, and have a low resistance to starvation. Improvements in algal food supplied to adults increases the proportion of flies reproducing, fecundity, and egg production rates. Reproductive effort has a negative impact on survival only when food is limiting. These results suggest that direct and indirect effects of changing salinity may play an important role in shaping life history patterns and regulating population dynamics of the alkali fly.

Book Thorp and Covich s Freshwater Invertebrates

Download or read book Thorp and Covich s Freshwater Invertebrates written by James H. Thorp and published by Elsevier. This book was released on 2014-09-06 with total page 1149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich’s Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. Global coverage of aquatic invertebrate ecology Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group Separate chapters on invasive species and economic impacts and uses of invertebrates Eight additional chapters on insect orders and a chapter on freshwater millipedes Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series Identification keys to lower taxonomic levels

Book Great Salt Lake Biology

    Book Details:

  • Release : 2020-07-03
  • ISBN : 3030403521
  • Pages : 529 pages

Download or read book Great Salt Lake Biology written by Bonnie K. Baxter and published by Springer Nature. This book was released on 2020-07-03 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Great Salt Lake is an enormous terminal lake in the western United States. It is a highly productive ecosystem, which has global significance for millions of migrating birds who rely on this critical feeding station on their journey through the American west. For the human population in the adjacent metropolitan area, this body of water provides a significant economic resource as industries, such as brine shrimp harvesting and mineral extraction, generate jobs and income for the state of Utah. In addition, the lake provides the local population with ecosystem services, especially the creation of mountain snowpack that generates water supply, and the prevention of dust that may impair air quality. As a result of climate change and water diversions for consumptive uses, terminal lakes are shrinking worldwide, and this edited volume is written in this urgent context. This is the first book ever centered on Great Salt Lake biology. Current and novel data presented here paint a comprehensive picture, building on our past understanding and adding complexity. Together, the authors explore this saline lake from the microbial diversity to the invertebrates and the birds who eat them, along a dynamic salinity gradient with unique geochemistry. Some unusual perspectives are included, including the impact of tar seeps on the lake biology and why Great Salt Lake may help us search for life on Mars. Also, we consider the role of human perceptions and our effect on the biology of the lake. The editors made an effort to involve a diversity of experts on the Great Salt Lake system, but also to include unheard voices such as scientists at state agencies or non-profit advocacy organizations. This book is a timely discussion of a terminal lake that is significant, unique, and threatened.

Book The Mono Basin Ecosystem

    Book Details:
  • Author : National Research Council
  • Publisher : National Academies Press
  • Release : 1987-02-01
  • ISBN : 0309037778
  • Pages : 289 pages

Download or read book The Mono Basin Ecosystem written by National Research Council and published by National Academies Press. This book was released on 1987-02-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mono Basin is a closed hydrologic basin spanning the border between California and Nevada. Los Angeles has been diverting streams since 1941 that normally would flow into Mono Lake. It has been predicted that continued diversion will have major ecological consequences for the natural resources of the Mono Basin National Forest Scenic Area. This book studies the ecological risk assessment that considers the effects of water diversions on an inland saline lake. It examines the hydrology of the Mono Basin, investigates the lake's physical and chemical systems, studies the biological relationships, and predicts the effects of changes in lake levels on the ecosystem.

  • ISBN : 9048190886
  • Pages : 372 pages

Download or read book Pond Conservation in Europe written by Beat Oertli and published by Springer Science & Business Media. This book was released on 2010-09-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ponds are an exceptional freshwater resource around the world and represent thirty percent of the global surface area of standing water. Furthermore, the millions of ponds which exist exhibit a particularly high biodiversity and have a high potential for ecosystem functions and services. Despite these impressive features, ponds face many threats from a variety of human activities and receive little or no protection under European and national legislation. Consequently, there is an urgent need to protect, consolidate and increase the pond resource in Europe. In order to achieve these objectives, the European Pond Conservation Network (EPCN) was launched 2004 in Geneva. Its aim is to promote the awareness, understanding and conservation of these small water bodies in the European landscape. This volume of “Developments in Hydrobiology” presents a selection of 31 papers presented during EPCN conferences held in 2006 in France (Toulouse) and in 2008 in Spain (Valencia). They represent a diverse collection of themes from across the continent and North Africa and present new and original insights into topics as wide ranging as pond biodiversity; human disturbance; landscape ecology; ecological assessment and monitoring; practical management measures; ecological restoration; hydrology and climate change; invasive species and threatened species.

Book The Mar Chiquita Salt Lake  C  rdoba  Argentina

Download or read book The Mar Chiquita Salt Lake C rdoba Argentina written by Enrique H. Bucher and published by Springer. This book was released on 2019-06-26 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive, updated syntheses of all the information available on Mar Chiquita, covering various aspects of the geography, geological history, biology and ecology of the site, as well as a detailed analysis of the current land-use patterns, environmental threats, and conservation issues. Mar Chiquita, located in the province of Cordoba, Argentina, is a protected wilderness area that includes South America’s largest saline lake and wetland. It has a very rich bird biodiversity, including three of the six species of flamingos that exist in the world, and high numbers of intercontinental migratory shorebirds. For this reason, the area has been declared an International Site by the Ramsar Convention on Wetlands of International Importance, and also a Site of Hemispheric Importance by the Western Hemisphere Shorebird Reserves Network. Largely unknown until very recently, particularly in terms of the English literature, the site is rapidly gaining international visibility, not only in terms of scientific research, but also as site of interest for the nature lovers around the globe. Written in a language accessible to the non-specialists, the book focuses on integrating the dynamic, functional processes in the ecosystem, while at the same time providing the necessary descriptive information. Accordingly, it is of interest to scientists from diverse disciplines interested in saline wetlands, as well as to students, managers, and the general public.
