This book was released on 2000 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater unionid mussels are one of the most rapidly declining components of North American freshwater biodiversity. Although they are of ecological and economic significance, we are faced with a considerable deficit in our knowledge of unionid life history and ecology. In particular, growth rates and longevity have been approached using erroneous techniques. Consequently, much of conventional management for these declining species may be inadequate. This thesis explores a new method for estimating age in unionid mussels. Through applying an inversion of the von Bertalanffy growth equation to mark and recapture-inferred growth rates, true ages of unionid mussels were estimated. Apparently, mussels may reach ages much older than previously expected. With ages that may exceed a century in some populations, freshwater mussels may be among the oldest living creatures in the world. The extreme age and slow growth of these bivalves may be, in part, at the root of their failure to support sustainable fisheries. Although freshwater mussel populations in the United States have been intensively exploited for various economic interests for over 100 years, harvests have been volatile and many mussel populations presently seem commercially unviable. The extreme age, slow growth, and reproductive ecology of these mollusks are compatible with an Allee effect whereby exploitation may rapidly lead to decreased per capita reproduction and even extinction. These aspects of mussel life history and reproductive ecology parallel those of many classically overexploited species and the Allee effect may be more common than previously expected in exploited populations.

This book was released on 2003 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: A habitat survey of the Clinch River, Virginia was conducted from Blackford, Clinch River Kilometer (CRK) 478 to the Tennessee border, CRK 325. Physical characteristics identified in the survey were combined with water quality and impact source data to develop a habitat suitability index for freshwater mussels within this study reach. Model parameters were indexed and weighted to give a final suitability ranking. Habitat units having the highest overall ranking included: Nash Ford (CRK 449), Artrip (CRK 442), several riffles and runs below Carterton (CRK 417), upstream of Mill Island (CRK 389.5), and Pendleton Island (CRK 365), and Speers Ferry (CRK 333-325). Potential locations for habitat restoration projects and additional monitoring were also identified.
