The Comparison Of Different Wetland Fish Assemblages Over Time, Robert Edward Adelstein
The Comparison Of Different Wetland Fish Assemblages Over Time, Robert Edward Adelstein
Theses, Dissertations and Capstones
Wetlands provide essential ecosystem services. Historically, we have drained and filled 73% of wetlands for agricultural use throughout the United States from the 1780s to the 1980s (Dahl, 1990). A nationwide focus on restoring wetlands has since occurred. Literature on restored/mitigated wetlands is rife with examples that do and do not support the same ecosystem services as natural wetlands (Langston, 1997; Meil, 2014). Restoration of wetlands occurred at the Green Bottom Wildlife Management Area (GBWMA) over several decades. Various sections of the wetland were classified by age, water depth, and vegetation. One hypothesis was that differences in fish assemblage would …

Using Occupancy Modeling For Protocol Development And Habitat Assessment Of Necturus Maculosus In A Large Nagivational River, Alyssa Rachelle Jones

Determining the survey effort required to reliably detect population change can be challenging for cryptic, elusive species. The secretive nature of amphibians makes it difficult to monitor population status and gather information about their natural history, including habitat use, which is essential for amphibian monitoring programs. The goals of this study were to examine if detection probabilities were affected by bait (i.e., light and food), breeding activity, and environmental covariates in a population of fully aquatic salamanders, Necturus maculosus. I evaluated the effectiveness of three bait treatments (light bait, food bait, combined light and food bait) and an unbaited …
Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken
Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken
Theses, Dissertations and Capstones
The ability to sequence bacterial genetic material directly from environmental samples has unlocked the field of metagenomics. Next-generation sequencing techniques, such as pyrosequencing, have been instrumental in providing knowledge about bacterial communities. This study focused on identifying the bacterial diversity of the Ohio River via pyrosequencing and compared the diversity of cultivable bacteria versus the entire river community. To ensure the maximum number of cultivable bacteria was obtained, cultures were grown on nonselective media and incubated at river temperature. Bacterial DNA was extracted, sequenced, and classified. The dominant phyla for the Ohio River included Cyanobacteria (38-66% of the total), Actinobacteria …
The Naiads (Mollusca: Unionidae) From Two Prehistoric Sites Along The Ohio River, Mason County, West Virginia, Beverly Dawn Spurlock
The Naiads (Mollusca: Unionidae) From Two Prehistoric Sites Along The Ohio River, Mason County, West Virginia, Beverly Dawn Spurlock
Theses, Dissertations and Capstones
Archeological naiad valves representing 29 species were recovered from two Late Prehistoric Indian villages along the Ohio River, Mason County, West Virginia. Surface collections and limited excavation provided a total of 1,599 identifiable valves and valve fragments. Differences in species compositions and relative abundances between the two middens were noted. Samples from the Rolf Lee Farm Site (46MS51) contained 28 species while the Lewis-Old Town Farm Site (46MS57) produced only 23 species. Comparisons were made with other nearby prehistoric shell deposits and also with more recent twentieth century collections from this reach of the river. Nine of the archeological species …
