“…Species diversity ranged from 1 to 10 species per site (median = 7 species). Mussel assemblages were less diverse than found in southwestern Ontario rivers (Lake Erie and Lake St. Clair watersheds) (Metcalfe- Smith et al, 1998). Seventytwo percent of species detections were from the collection of live individuals and 28% from the collection of fresh shells.…”

-Inventories and population monitoring are essential activities supporting the conservation of freshwater mussel diversity in Canadian rivers. Despite widespread use of timed-search methods to survey river mussels, the relationship between species detection and search effort has received limited study. In this study, repeat-sampling data from 54 Ontario river sites were used to estimate: (1) species detection probabilities; (2) the number of sampling events required to confidently detect species; and, (3) the power of timed-search surveys to detect future distribution declines. Mussels were collected using visual and tactile methods, and collection data were recorded separately for each 1.5 h of search time (up to 4.5 h). Thirteen species were collected; including two endangered species (Rainbow Villosa iris and Eastern Pondmussel Ligumia nasuta). In all cases, species detection was imperfect. However, detection probabilities (p) for most species were high (>0.69). Two repeat 4.5 h surveys are required to confidently assess whether most (83%) species are present at a site. Search effort had a positive effect on estimates of species richness, detection probability and site occupancy, and the power to detect future distribution declines. At all levels of sampling effort, detection probability and site occupancy estimates were positively correlated to mussel abundance.

“…Populations of A. plicata have been historically widespread and common (Cummings and Mayer 1992) and were even commercially harvested until a few years ago. In the three drainages sampled, A. plicata is an abundant species and is commonly found in large numbers (Cummings and Mayer 1992;Hoggarth 1995Hoggarth -1996Metcalfe-Smith et al 1998;Vaughn and Spooner 2004). Therefore, high effective population size and low genetic drift is a viable hypothesis for the lack of genetic structure at large geographic scales.…”

“…Our study focuses on Amblema plicata (Say 1817), a species of freshwater mussel that is widespread in medium and large rivers of the Mississippi and Great Lakes drainages (Cummings and Mayer 1992;Hoggarth 1995Hoggarth -1996Metcalfe-Smith et al 1998;Vaughn and Spooner 2004). Because this species is relatively common, its population genetic structure is likely to be more intact than that of species that have become threatened or endangered.…”

Population genetics of the freshwater mussel, Amblema plicata (Say 1817) (Bivalvia: Unionidae): Evidence of high dispersal and post-glacial colonization

Over 70% of North American freshwater mussel species (families Unionidae and Margaritiferidae) are listed as threatened or endangered. Knowledge of the genetic structure of target species is essential for the development of effective conservation plans. Because Ambelma plicata is a common species, its population genetic structure is likely to be relatively intact, making it a logical model species for investigations of freshwater mussel population genetics. Using mtDNA and allozymes, we determined the genotypes of 170+ individuals in each of three distinct drainages: Lake Erie, Ohio River, and the Lower Mississippi River. Overall, within-population variation increased significantly from north to south, with unique haplotypes and allele frequencies in the Kiamichi River (Lower Mississippi River drainage). Genetic diversity was relatively low in the Strawberry River (Lower Mississippi River drainage), and in the Lake Erie drainage. We calculated significant among-population structure using both molecular markers (A.p. F st = 0.15, h st = 0.12). Using a hierarchical approach, we found low genetic structure among rivers and drainages separated by large geographic distances, indicating high effective population size and/or highly vagile fish hosts for this species. Genetic structure in the Lake Erie drainage was similar to that in the Ohio River, and indicates that northern populations were founded from at least two glacial refugia following the Pleistocene. Conservation of genetic diversity in Amblema plicata and other mussel species with similar genetic structure should focus on protection of a number of individual populations, especially those in southern rivers.

“…Spurred by conservation concern about mussels, intensive field surveys over the last 30 years have made possible a detailed accounting of recent species losses and declines at multiple scales across much of North America (e.g. Metcalfe-Smith et al 1998;Brim Box and Williams 2000;Warren and Haag 2005). In addition, a large body of historical and pre-Columbian material exists that allows assessment of trends prior to recent surveys.…”
