Genetic And Morphological Assessment Of Pigtoe Mussels (unionidae: Pleurobemini: Fusconaia/pleurobema Spp.) in Ozark Drainages
… within drainages of the Ozarks. Further, Pleurobema rubrum and P. sintoxia have been shown to be possible conspecifics despite have differing shell morphologies. This study sought to use the COI mitochondrial gene to investigate the taxonomic identity of Pleurobemini specimens from within …

Distribution, Genetic Characterization, and Life History of the James spinymussel, Pleurobema collina (Bivalvia: Unionidae), in Virginia and North Carolina
… along the Atlantic slope; James spinymussel (Pleurobema collina), Tar spinymussel (Elliptio steinstansana), and Altamaha spinymussel (E. spinosa). The James spinymussel was listed as endangered in 1988, and was until recently considered to be endemic to the James River basin (Clarke and Neves …

Development of Molecular and Morphological Resources for Identification and Monitoring of Freshwater Mussel Species in the Genera Fusconaia and Pleurobema in the Green River, Kentucky
… mussel species in the genera Fusconaia and Pleurobema are particularly challenging to identify in the field. In this study, mussels from these genera were collected from the Green River, Kentucky for genetic and morphological analyses. I used molecular markers to detect any cryptic species …

Assessment of morphological and molecular genetic variation of freshwater mussel species belonging to the genera Fusconaia, Pleurobema, and Pleuronaia in the upper Tennessee River basin
… freshwater mussels in the genera Fusconaia, Pleurobema, and Pleuronaia were collected primarily in the upper Tennessee River basin from 2012 to 2014 for phylogenetic and morphological assessments. Freshwater mussels in these genera are similar in appearance, hence the need for phylogenetic …

Population Genetic Structure of Unionid Mussels Across Multiple Gulf Drainages
… threatened mussel species of family Unionidae: Pleurobema riddellii (Louisiana 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 …

Survival and condition of riverine freshwater mussels (Unionidae) confined in cages suspended in ponds
… highest survivals (x=83%), whereas survival of Pleurobema cordatum and Lampsilis ovata was significantly lower, with 54% and 14%, respectively. Survival of five mussel species in a pond at Blacksburg was high (x=79%) after 7 months, but a nearly complete die-off of captive mussels occurred …

Acute Toxicity of Ammonia and Copper to Mussel (Bivalvia: Unionidae) Glochidia Inside and Outside of Conglutinates
… investigated, one with cohesive conglutinates (Pleurobema sintoxia) and one with sheathed conglutinates (Ptychobranchus occidentalis). Glochidia of both species remained viable longer within conglutinates than in water, both in the presence and absence of toxicants. P. occidentalis glochidia …

Distribution and life history of the endangered James Spinymussel, pieurobema collina (bivalvia: unionidae)
Distribution of the James spinymussel (Pleurobema collina) and aspects of its life history were studied from June 1987 to October 1989. Field and laboratory observations were used to determine gravidity and glochidial release periods, fish host requirements, age class structure, growth …

An Evaluation of the Survival and Growth of Juvenile and Adult Freshwater Mussels at the Aquatic Wildlife Conservation Center (AWCC), Marion, Virginia
… iris, V. vanuxemensis, Amblema plicata, and Pleurobema oviforme, served as surrogates for endangered species and were relocated to the AWCC. Three energy reserves (glycogen, protein, and lipid) were measured seasonally (fall 2002 to summer 2004) from mantle tissue and compared between AWCC …
