Biology, Captive Propagation, and Feasibility of Pearl Culture in the Pink Heelsplitter (Potamilus Alatus) (Say, 1817) (Bivalvia: Unionidae)
Pink heelsplitter (Potamilus alatus) mussels collected from Kentucky Lake, TN were held at two bottom locations (0.6 m, 2.5 m) and suspended in pocket nets (at depth about 1.0 - 1.5 m) in a pond at the Freshwater Mollusk Conservation Center (FMCC), Virginia Tech, for 1 yr. Survival of mussels after …

Population Genetic Structure of Unionid Mussels Across Multiple Gulf Drainages
… Pigtoe), Fusconaia askewi (Texas Pigtoe), and Potamilus amphichaenus (Texas Heelsplitter). Principal component and admixture analyses paired with genetic distance estimates (GST) of these species demonstrated clear interspecific and intraspecific differentiation across separate drainages as …

Crayfish Predation on Juvenile Freshwater Mussels (Bivalvia: Unionidae)
… larger individuals of a thin shelled species (Potamilus alatus) than of a heavier shelled species (Lampsilis siliquoidea). Based on these laboratory tests, it appears that mussels up to 50 mm in length of some native species may remain vulnerable to ringed crayfish predation. Many aquatic …

A Quantitative Survey of the Freshwater Mussel (Unionidae) Fauna in Honeoye Creek, New York
… were not collected for 2 Leptodea fragilis, Potamilus alatus, and Truncilla truncata, a finding consistent with the low abundances of these three species in Honeoye Creek. While these data provide a base-line for freshwater mussel diversity, abundance and distribution, additional research is …

Freshwater Mussels Vary in Substrate Preference and Mobility in Pairwise Behavioral Experiments
… showed little to no substrate preference (Potamilus purpatus and Plectomerus dombeyanus). Some species (e.g., L. teres) moved horizontally ~22 times their body length, while some were immobile (e.g., P. dombeyanus). Substrate preference was consistent with previously proposed habitat …

Characterization of Suitable Habitats for Freshwater Mussels in the Clinch River, Virginia and Tennessee
… preferences of Actinonaias pectorosa, Potamilus alatus, and Ptychobranchus subtentum. These species appeared less stressed in the fastest flow treatment, demonstrating significantly higher oxygen consumption and oxygen-to-nitrogen (O:N) ratios than in slower flow treatments. Only P. …
