Report provides information on distribution, abundance, and health of birds, mammals, reptiles and amphibians, fishes, invertebrates, plants, terrestrial ecosystems, aquatic ecosystems, coastal and marine ecosystems, riparian ecosystems, the Great Plains, Interior West, Alaska, and Hawaii. It also discusses special issues: global climate change, human influences, non-native species, and habitat assessments.
"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.
The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.
A survey to assess community characteristics, density, population demography of dominant species, and the presence of rare or endangered species of mussels (Family: Unionidae) was conducted in selected reaches of the Quiver River and Bogue Phalia, Mississippi, in 1994 and 1995 for the U.S. Army Engineer District, Vicksburg. Results are being used to assess the economic value of mussels in the project area and to determine the environmental effects of proposed maintenance dredging. The project area included a section of the Quiver River between its confluence with the Big Sunflower River immediately north of Highway 82 in Sunflower County to the Leflore-Tallahatchie county line. In the Bogue Phalia, the study area consisted of a reach between Highway 82 and Rosedale, west-central Bolivar County. Twenty-two species of native freshwater mussels were collected in the Quiver River; 26 sites were sampled using qualitative methods, and a total of 2,238 mussels were collected. The dominant mussel was Amblema p. plicata, which comprised over 67 percent of the mussel fauna. Plectomerus dombeyanus comprised 20 percent of the mussels. Overall species diversity (0.67 to 0.90) was low, mainly because of the dominance of A. p. plicata. Evidence of recent recruitment was low; approximately 7 percent of the species and 0.15 percent of the individuals collected were less than 30 mm total shell length. Overall mean density ranged from less than 8.6 individuals/square meter at River Mile (RM) 6.4 to 92.3 individuals/square meter at RM 19.7.
Since the early 1800s, people have made a living fishing and harvesting mussels in the lower Ohio Valley. These river folk are conscious of an occupational and social identity separate from those who earn their living from the land. Sustained by a shared love of the river, deriving joy from the beauty of their chosen environment, and feeling great pride in their ability to subsist on its wild resources and to master the skills required to make a living from it, many still identify with the nomadic houseboat-dwelling subculture that flourished on the river from the early nineteenth century to the 1950s. Today's community of fisherfolk is small and economically marginal, but their activities sustain a complex set of traditional skills and a body of verbal folklore associated with river life. In Flatheads and Spoonies, Jens Lund describes the activities, boats, gear, verbal lore, and sense of identity of the fisher folk of the lower Ohio River Valley and provides historical and ethnobiological background for their way of life. Lund connects the importance of river fish in the diet of inhabitants of the valley to local fishing activities and explores the relationship between river people and those whose culture is primarily land-based, painting a colorful portrait of river fishing and river life. This book offers a look—historical and ethnographic—at a little-known aspect of traditional life in the American Midwest, still surviving today despite immense changes in environment, resources, and economic base.
This state-of-the-art, research level text considers the growing volume of research at the interface of hydrology and ecology and focuses on: the evolution of hydroecology / ecohydrology process understanding hydroecological interactions, dynamics and linkages methodological approaches detailed case studies future research needs The editors and contributors are internationally recognised experts in hydrology and ecology from institutions across North America, South America, Australia, and Europe. Chapters provide a broad geographical coverage and bridge the traditional subject divide between hydrology and ecology. The book considers a range of organisms (plants, invertebrates and fish), provides a long-term perspective on contemporary and palaeo-systems, and emphasises wider research implications with respect to environmental and water resource management. Hydroecology and Ecohydrology is an indispensable resource for academics and postgraduate researchers in departments of physical geography, earth sciences, environmental science, environmental management, civil engineering, water resource management, biology, zoology, botany and ecology. It is also of interest to professionals working within environmental consultancies, organizations and national agencies.
