This book was released on 2010 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic impacts have degraded the function of many large river-floodplain ecosystems. Habitat rehabilitation/management, in the form of water level management, often emphasize the promotion of wetland vegetation. Wetland management is believed to enhance macroinvertebrate populations. To test this assumption, I evaluated macroinvertebrate response to habitat rehabilitation, habitat type, and vegetation density in Swan Lake, an Illinois River floodplain lake located in Calhoun County, Illinois. Results indicated wetland rehabilitation generally enhanced macroinvertebrate availability for spring migrating waterfowl. Results comparing habitats available at Swan Lake indicated moist soil habitats provided greater abundance and biomass of water column macroinvertebrates in the fall season, while spring was more variable. In addition, benthic macroinvertebrate communities indicated inconsistent differences between habitat types. Fall estimates indicated inundation can be an effective mechanism for controlling the timing of water column macroinvertebrate colonization. Vegetation manipulations did not consistently impact macroinvertebrate taxonomic and functional groups, but results indicated some specific taxonomic groups were influenced by vegetation presence/absence and were correlated (positively or negatively) with coarse organic matter. This research supported the principle that management of habitat and hydrologic regime can be effective tools for improving macroinvertebrate populations in order to optimize nutritional resources for waterfowl.

Johnson and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's Abstract: River floodplain habitats of the Southeastern United States are sites of high biological productivity that rely on a predictable flooding event as a keystone process. This study took place in a river-floodplain area of the Altamaha River, an unimpounded large-order river in the Coastal Plains region of the US. This study aims to investigate how aquatic macroinvertebrate communities changed over the course of the annual flood pulse. I predicted that the communities would be different and that the differences would be driven by hydrology at the main stem and organic matter standing stock availability. I took quantitative samples of benthic macroinvertebrates monthly from December 2011-April 2012 and from December 2012- April 2014. Invertebrate abundance was assessed and biomass was obtained using published length-mass regressions. Year 1 (2011-2012) was characterized by severe drought. And Year 2 was characterized by a large flooding event. There was a significant difference between the communities. In year 1 the community was influenced by hydrology and high FBOM standing stocks. In year 2 the community was influenced by hydrology and low CBOM standing stocks. This study shows the importance of a flooding event in river floodplain systems and supports the idea that floodplains act as a source of organic matter to the main stem and are sites of high biological productivity especially from aquatic macroinvertebrates. As unimpounded rivers are becoming increasingly rare, it is important to understand how these systems function in both normal and abnormal (i.e., drought vs. flood) conditions.

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Stream Hydrology written by Nancy D. Gordon and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals. Stream Hydrology: An Introduction for Ecologists Second Edition documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. * Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management. * Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification. * Critical reviews of the successes and failures of implementation. * Revised and updated windows-based AQUAPAK software. This book is essential reading for 2nd/3rd year undergraduates and postgraduates of hydrology, stream ecology and fisheries science in Departments of Physical Geography, Biology, Environmental Science, Landscape Ecology, Environmental Engineering and Limnology. It would be valuable reading for professionals working in stream ecology, fisheries science and habitat management, environmental consultants and engineers.

Download or read book Invertebrates in Freshwater Wetlands written by Darold Batzer and published by Springer. This book was released on 2016-02-05 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.
