Freshwater Mussels (Bivalvia: Margaritiferidae And Unionidae) Of The Buffalo River Drainage, Tennessee, Matthew Philip Reed
Freshwater Mussels (Bivalvia: Margaritiferidae And Unionidae) Of The Buffalo River Drainage, Tennessee, Matthew Philip Reed
Masters Theses
The Buffalo River in Tennessee once hosted a rich population of freshwater mussels. During the 1980s, monitoring efforts demonstrated evidence of drastic declines and extirpation of entire assemblages. Increases in municipal development in the headwater tributaries and agriculture in the main stem of the Buffalo River are suspected causes for mussel community declines throughout the river. In 2011, collection data documented evidence of recovery in the lower Buffalo River. The aims of this project were: 1) to update the status, distribution, and species composition of mussels in the Buffalo River and its major tributaries through qualitative sampling, and 2) to …
Habitat Selection And Partitioning Among Darters In Two Tributaries Of The Clinch River, And Stream Restoration Effects On Substrate Profile, Daniel James Walker
Habitat Selection And Partitioning Among Darters In Two Tributaries Of The Clinch River, And Stream Restoration Effects On Substrate Profile, Daniel James Walker
Masters Theses
The group of fish referred to as darters is extremely biodiverse. Often, several closely related species will inhabit the same areas of streams, and prior research has investigated how these species may be partitioning the resources in low-order streams in which they are sympatric. The habitat partitioning of darters in two streams in the Clinch River system, Coal and Cove Creeks, was investigated. The study sites were picked due to their involvement in both physical and biological stream restoration efforts within the last several years, including the collection, translocation, and reintroduction of rainbow darters (Etheostoma caeruleum) from reference sites in …
Microglia Respond To Both Permanent And Temporary Deaferentation In The Adult Zebrafish Olfactory Bulb, Amanda K. Mckenna
Microglia Respond To Both Permanent And Temporary Deaferentation In The Adult Zebrafish Olfactory Bulb, Amanda K. Mckenna
Masters Theses
The major goal of this study was to investigate a microglial response following deafferentation in the adult zebrafish, Danio rerio, olfactory bulb. Microglia were identified in the olfactory bulb using the 4c4 antibody and phagocytic-dependent labeling (DiA). Microglia responded to both methods of deafferentation namely, permanent (cautery) and temporary (Triton X- 100). On one and three days following both permanent and temporary deafferentation there was a significant increase in microglia in the treated olfactory bulb. At five and seven days after permanent and temporary deafferentation there was no longer a significant difference between the treated and untreated olfactory bulbs, …
