Ecological Effects of Water-level Fluctuations in Lakes
Author: Karl M. Wantzen
Publisher: Springer Science & Business Media
ISBN: 1402091923
Category : Technology & Engineering
Languages : en
Pages : 184
Book Description
Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

Factors Affecting Invertebrate and Fish Communities in Coastal Wetlands of the Great Lakes

Languages : en
Pages : 213
Book Description
I examined differences in fish and benthic invertebrate communities in open Great Lakes coastal wetlands versus impounded wetlands. Open Great Lakes coastal wetlands (GLCW) are wetlands along the Laurentian Great Lakes that are connected to the lakes and are influenced by lake water level fluxuations. These connections may be permanent or may only be present when lake water levels are high. Many fish species in the Great Lakes migrate into these open coastal wetlands to breed and feed on abundant invertebrate food resources. The GLCW are also important habitats for unionid mussels, that persist in these refuges even though they have been nearly extirpated from the Great Lakes. Unionids may also provide a unique microhabitat for epizoic invertebrates that live attached to their shells. Migratory shorebirds also feed on invertebrates in these wetlands during their spring and fall migrations. Thus, I also examined if fish and migratory shorebird preyed on similar invertebrate taxa in open coastal wetlands. My research was performed at Ottawa National Wildlife Refuge in Oak Harbor, OH. This site includes a coastal wetland along Lake Erie, as well as impounded wetlands, where water levels are managed for bird habitats and to control invasive species. In my first study, I found that both fish and invertebrate communities differed between open coastal wetlands and impounded wetlands, probably due to factors such as predation, competition and abiotic conditions. For example, invertebrate community differed among water depths in open coastal wetlands but not in impounded wetlands. I also used exclosures to test if fish and shorebirds impact benthic and epizoic invertebrate densities and diversities. I found that fish reduce total invertebrate density and diversity. However, some invertebrate taxa increased after competitively dominant taxa were reduced. I found no impact of shorebird predation on benthic invertebrates in these areas. I also found that common carp were an important predator of benthic invertebrates. They also reduced epizoic invertebrates (e.g., zebra mussels) on native unionid mussels.
