DOWNLOAD EBOOKPearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

DOWNLOAD EBOOKIn 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.

DOWNLOAD EBOOKAll those who think that bivalves are boring are in the best company. Karl von Frisch is reported to have turned the pages more quickly in texts where bivalves were treated because, according to him, they literally lack any behaviour. The fact that they can filtrate huge amounts of water, burrow into the sedi ment, actively swim, drill holes into rocks and boats or detect shadows with the aid of pretty blue eyes located on the rim of their mantle obviously left v. Frisch unimpressed. Why, then, a book on the large freshwater mussels (Naiads or Unionoida), which on first sight are much less spectacular than the marine ones? The main reason is that they are keepers of secrets which they reveal only on close and careful inspection. This is not only true for the pearls some species produce and which over centuries have contributed to the treasures of bishops and kings, but particularly for their ecology: their life cycles are linked with those of fishes, some can occur in incredible densities and some can live for more than 100 years. Thus, the presence or absence of naiads in a lake or stream has manifold implications.

DOWNLOAD EBOOKThe Cumberland and Tennessee River drainages harbor high diversity and endemism of freshwater mussels. The faunas of the Harpeth River drainage and Duck River tributaries have been disproportionally understudied relative to other Cumberlandian streams. Forty-two sites on 23 tributaries in the Harpeth River drainage and a 21-kilometer reach of the main channel were assessed qualitatively for freshwater mussels. Relic shells of four species were observed in eight sites on four of the tributaries. Twenty species were observed in the main channel including the discovery of a new Harpeth River drainage record: Simsponaias ambigua. Catch per unit effort (CPUE) ranged from 0.0 to 32.0 mussels/h. Lampsilis fasciola and Potamilus alatus were the most abundant species. Mussel populations were fragmented and all species exhibited primarily large size-classes. Eighty-three sites on 37 tributaries in the upper and middle Duck River drainage were sampled qualitatively. Nineteen species were observed and 12 were collected live or fresh dead, and CPUE ranged from 0.0 to 58.0 mussels/h. Villosa vanuxemensis and Villosa taeniata were the most abundant and widespread species observed. Live mussels were found in only five tributaries, although mussels historically occurred in 17 of the sampled streams. Length frequency analysis indicated recent recruitment for four species in Big Rock Creek. Results of canonical correspondence analysis for both drainages revealed no association between environmental variables and mussel community structure (live and fresh dead individuals combined), likely a result of low densities. Two sites on Big Rock Creek in the Duck River drainage were sampled quantitatively using 0.25-m2 quadrats. Densities were 0.33 and 1.27 mussels/0.25m2 and species richness ranged from four to five. Quantitative sampling indicated that qualitative timed searches may be sufficient for detecting recruitment in small streams. Anthropogenic alteration has resulted in extensive loss of freshwater mussel habitat, leading to local extirpations and a reduction of diversity and abundance in both watersheds.
