Abstract From 2009–2012 detailed distribution data, information to update conservation status, and additional life history and habitat observations were obtained for six rare crayfishes in Western North Carolina. The Hiwassee Headwaters Crayfish, Cambarus (Puncticambarus) parrishi, continues to occupy a very limited range in Clay County, with most known occurrences from the Tusquitee Creek system. The Chauga Crayfish, C. (P.) chaugaensis, appears to be abundant throughout much of its range in the upper Savannah River Drainage, in Transylvania, Jackson, and Macon counties. The French Broad River Crayfish, C. (P.) reburrus, has declined in Madison and Buncombe counties, while populations in Transylvania County appear to have remained relatively stable. The Broad River Stream Crayfish, C. (Cambarus) lenati continues to occur primarily in the upper First Broad River drainage where it is common in some streams in Rutherford County. The Broad River Spiny Crayfish, C. (P.) spicatus is rare but continues to exist in two isolated populations: upper First Broad and North Pacolet river drainages. The Little Tennessee River Crayfish, C. (P.) georgiae continues to occupy Jackson and Macon counties where it is most abundant in the upper Little Tennessee River Drainage. No range expansions were observed for any of these crayfish species.

Genotypes from 10 polymorphic DNA microsatellite loci were used to make assessments of population structure, measurements of gene flow, and attempts to genetically segregate polymorphic host fish-attracting mantle displays for the wavy-rayed lampmussel, Lampsilis fasciola Rafinesque, 1820 — an endangered species in Canada. Specimens were collected from seven localities — six in the Great Lakes drainages of Ontario, Canada, and one from the Little Tennessee River in North Carolina, USA. Four distinct and sympatric mantle display morphologies were observed on female L. fasciola. Displays could not be distinguished genetically using analysis of molecular variance and genotypic assignment tests. The diversity of mantle displays was correlated with the overall genetic diversity observed among populations of L. fasciola. In managing populations of L. fasciola for propagation, augmentation, and translocation, polymorphic lures should be represented in proportion to what is observed in wild populations. Through moderately high FST values and high assignment to population in genotype assignment tests, genetic structure was evident among the river drainages. Within-drainage gene flow was very high, and sampling localities within the Ontario drainages displayed panmixia. Efforts in artificial propagation and possible translocations to reintroduce or augment populations should be made to maintain the substantial levels of genetic variation while maintaining distinctiveness.

AbstractIn the spring of 1783, Oconastota, the Great Warrior and principal chief of the Overhill Cherokees, died and was buried at his beloved town of Chota on the Little Tennessee River in present day Monroe County, Tennessee. In the fall of 1969, the Department of Anthropology of the University of Tennessee, while conducting archaeological investigations at this site, disinterred a burial which exhibits striking correlations with the historic accounts of Oconastota and his inhumation.
