This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding patterns of genetic differentiation within and across wildlife populations is a key component to parsing the demographic and ecological processes that govern the spatial structure and evolutionary trends of a given species. As molecular and computational techniques continue to advance, these data have become critical tools in delineating population boundaries as well as informing appropriate management decisions. This study utilized a genotyping by sequencing (GBS) approach to study the genetic structure of three Texas state 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 interspecific and intraspecific differentiation across separate drainages as well as indications of isolation within drainages potentially facilitated by geographic barriers such as river impoundments and local environmental and ecological differences. These data present an effective approach to modeling genetic structure across a landscape that allow for precise inferences on population boundaries that inform conservation units (CU's) and the management strategies that use them (Funk et al., 2012; Smith et al., 2021).

Book excerpt: As filter feeders, North American freshwater mussels (Unionoida) are important for maintaining the quality of freshwater ecosystems. While North America has the most unionid species in the world, land-use modifications, impoundment of rivers, and invasive species have made unionids some of the most imperiled organisms in North America. It is therefore imperative that we thoroughly examine and understand unionid population and habitat characteristics to better conserve this species and maintain aquatic biodiversity. Macalester College's Aquatic Ecology Lab has monitored unionids in the St. Croix River for almost twenty years. Using their database, I completed a retrospective study investigating habitat and biogeographic variables and their influence associated with mussel distributions. Trends in the data indicated that higher mussel densities were associated with areas of Sub-critical flow (low Froude number), low shear stress, and coarse substrate but not with water depth & velocity. Also mussel species richness declined with greater distance upstream from the Mississippi. While both biogeographic and habitat factors were indicated as significant in determining mussel distributions (i.e. p-value

Book excerpt: Buck Creek is a fifth order tributary of the upper Cumberland River system in south-central Kentucky. Previous studies have shown that Buck Creek has a diverse aquatic fauna and a unionid community that is unique to the area. There have been four federally endangered mussels (Epioblasma brevidens, E. capsaeformis, Pegias fabula and Villosa trabalis) reported from the mainstem of Buck Creek. A qualitative sampling study and stress assesssment utilizing geographic information systems was conducted in 1997 to 1999 to determine the distribution of the freshwater mussels in relationship to the location of the sources of stress that may be adversely impacting the fauna.
