TLDR
There have been a number of mussel surveys (Smith, 1889, Coker, 1914, Grier and Mueller, 1922-23; Grier, 1922, 1926) in the Mississippi River to determine the relative value of these animals as a source of pearl button material as discussed by the authors.Abstract:
There have been a number of mussel surveys (Smith, 1889; Coker, 1914; Grier and Mueller, 1922-23; Grier, 1922, 1926) in the Mississippi River to determine the relative value of these animals as a source of pearl button material. Other studies (Cooper, 1834; Galtsoff, 1924; Wiebe, 1927; Ellis, 1931) were concerned more with general biological problems involving ecology, limnology and fisheries. Several valuable lists (Pratt, 1876; Call, 1885; Grant, 1885; Baker, 1903, 1905; Shimek, 1921; Dawley, 1947) furnish good records of species from various parts of this river. However, there has not been a single published report which gives an account of the distribution of these animals throughout the productive area of the main stream. A comprehensive survey made by Max M. Ellis and his staff during the summers of 1930 and 1931 now makes possible a report on those collections. These records are the only inclusive source of information concerning this unusually rich assemblage of naiades in our largest river.read more

Impending extinctions of North American freshwater mussels (Unionoida) following the zebra mussel (Dreissena polymorpha) invasion
TL;DR: A comparison of species loss at various sites before and after invasion indicates that D. polymorpha has accelerated regional extinction rates of North American freshwater mussels by 10-fold, and if this trend persists, the regional extinction rate for Mississippi basin species will be 12% per decade.

A review of the effects of heavy metals on freshwater mussels.
TL;DR: An understanding of the processes by which metals affect freshwater mussels would provide insights on the ecotoxicological significance of metal contamination to natural mussel populations and aid in the development of water-quality criteria that adequately protect mussels.

Parasitism and the unionacea (bivalvia)
TL;DR: It is proposed that the incorporation of a unique parasitic stage in the life‐cycle of unionaceans which involves an obligate relationship between a vertebrate host, usually a fish, and a highly modified larval stage, the glochidium, has had far‐reaching consequences with respect to overall morphology, extent of species' geographic ranges, and rate of speciation in the group.

Microhabitat use by an assemblage of stream-dwelling unionaceans (Bivalvia), including two rare species of Alasmidonta
David L. Strayer,Jonathan Ralley +1 more
TL;DR: It is suggested that including geomorphological descriptors of the streambed or working at spatial scales of hundreds of metres might be more useful than a traditional microhabitat approach for predicting the distribution of freshwater mussels in streams.

Distribution, abundance, and roles of freshwater clams (Bivalvia, Unionidae) in the freshwater tidal Hudson River
TL;DR: In this paper, an extensive series of PONAR grabs was used to determine the distribution and abundance of unionid clams in the freshwater tidal Hudson River, and the five species of unionids collected were distributed very unevenly within the river.

The Size of Certain Naiades from Western Lake Erie in Relation to Shoal Exposure
TL;DR: During July and August of 1937, three ecologically distinct habitats were studied in the island area of western Lake Erie, in an attempt to correlate, if possible, the limnological factors operating in these habitats, with the size of certain mussels living there.

Distribution of Aquatic Mollusks in Minnesota
TL;DR: A general survey of the fresh-water mollusks of Minnesota is of interest from a geographical point of view because the waters of Minnesota drain in three directions, namely south through the Mississippi River to the Gulf of Mexico, east through Lake Superior to the St. Lawrence River, and north through the Red and Rainy Rivers to Hudson Bay.
