Available in PDF, EPUB and Kindle. Book excerpt: Inspiration for the Clean Water Act (1972), the Cuyahoga River has been one of the most protected rivers in the country since the 1970s. Water quality is now within acceptable limits outlined by the Ohio Environmental Protection Agency, shoreline integrity has improved, and sediments mostly test free from toxins and heavy metals. With recovery, various faunal communities, such as freshwater mussels (family Unionidae), are expected to re-establish; no previous surveys of the Cuyahoga focus on this issue. To better understand whether mussel populations recovered as water quality improved within the Cuyahoga Watershed, surveys were completed by two-person teams for one hour each. Sites were selected to compare either with earlier surveys in the 1990s within the Upper Cuyahoga or with possible dam removal sites within the Middle and Lower regions of the River. Site choice depended upon access.Surveys in 2012 were consistent with trends observed in the 1990s in species richness and population size within the upper portions of the Cuyahoga. However, when resurveyed in 2016 at the same sites, both abundance and species richness declined even in generalist species, as live individuals counted declined from 389 to 111. Species richness declined from the original eight species to four found in the 2012 survey. No previous work existed to provide comparison to our 2015 survey of 20 sites. In all, only 37 live individuals, representing three species, were located. One live individual was located within the Lower Cuyahoga in 2016, after teams surveyed 15 sites, representing a significant decline in abundance and diversity as the Cuyahoga flows from Geauga County, Ohio to the Cuyahoga Valley National Park and into Lake Erie. The loss of freshwater mussels is a complex problem resulting from the building and release of impoundments, pollution, and flow dynamics, challenging the ability to isolate a single cause. Removal of dams has increased complexity of this problem in the lower portions of the river. As continued decline is expected, further work must be completed to understand how to restore this imperiled fauna.

Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatme
Download or read book The Freshwater Mussels of Ohio written by G. Thomas Watters and published by . This book was released on 2009 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early nineteenth century, a naturalist named Rafinesque stood on the banks of the Ohio River and began to describe the freshwater mussels he found there. Since that time, these animals have earned a place among the most imperiled animals in North America. Dozens of species have become extinct, and it is estimated that two-thirds of the remaining freshwater mussels face a similar fate. Yet, despite their importance, the mussels of Ohio remain a poorly documented and largely mysterious fauna. This book compiles existing research on Ohio's mussels, synthesizing works on genetics, biology, and systematics into one volume. Full-page color images depict shell variation, hinge detail, and beak sculpture. Full-page maps show the distribution of each species based upon the collections of numerous museums, with historical distributions dating from the 1800s. In addition to species accounts, the book has an introductory section that includes information on basic biology, human use, and conservation issues.--adapted from jacket.

Available in PDF, EPUB and Kindle. Book excerpt: Learn about the wonders of Lake Erie and Lake St. Clair in this fascinating and readable book. The most comprehensive reference source available about the lakes, Lake Erie and Lake St. Clair Handbook is an ideal guide for anglers, boaters, swimmers, beach walkers—anyone who uses and enjoys the lakes. The handbook explains, in simple terms, the reasons for the scenic beauty and the natural events that occur in the coastal and offshore waters of Lake Erie and Lake St. Clair, including the St. Clair, Detroit, and Niagara rivers extending from Sarnia, Ontario, to Niagara-on-the-Lake, New York. Individual chapters focus on the land, air, water, and life forms that comprise the natural history and environment of the region—the shoreline topography, wind and weather patterns, water temperature cycles and water level changes, the ecology, and indigenous animal life. Lake Erie and Lake St. Clair Handbook enhances our understanding and appreciation of the lakes and their surroundings by addressing fundamental questions about the Lake Erie region: • how Lake Erie was formed through glacial processes • why daily and seasonal weather patterns occur • causes of the water currents and waves • causes of temperature patterns in the lakes • the location of productive reef features • the species of fish and birds found in the area • the importance of the wetlands • the effect of current and past pollution on the aquatic life in the lakes

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
