Urbanization Increases Isolation Of A Threatened Fish Species In East Texas Streams: A 20-Year Perspective, Zachary Hutchens
Urbanization Increases Isolation Of A Threatened Fish Species In East Texas Streams: A 20-Year Perspective, Zachary Hutchens
Undergraduate Research Conference
We conducted monthly surveys of fish and in-stream habitat conditions from August 2020 to August 2021 in reaches along Banita Creek and La Nana Creek to investigate ecology and population status of the Sabine shiner (Notropis sabinae) within these streams. On average, Banita Creek had shallow water with low flow, more diverse instream habitats, and lower values of salinity, conductivity, and turbidity compared La Nana Creek. The movements of Sabine shiners were tracked monthly using Visual Implant Elastomer tags. Over a year-long survey, we collected 267 Sabine shiners from Banita Creek and 10 individuals from La Nana Creek. Out of …
Aquatic Macroinvertebrates As Sentinels Of Changes In Local Stream Conditions In East Texas, Courtney Plummer, Erin Shepta
Aquatic Macroinvertebrates As Sentinels Of Changes In Local Stream Conditions In East Texas, Courtney Plummer, Erin Shepta
Undergraduate Research Conference
Study objective: To use aquatic macroinvertebrates to assess the habitat quality and biological conditions of a stream, La Nana Creek, impacted by different land use.
Microplastics: Nacogdoches County’S Hidden Threat, Jordan Stanford, Sydney Matlock, Courtney Sims, Samantha Montes
Microplastics: Nacogdoches County’S Hidden Threat, Jordan Stanford, Sydney Matlock, Courtney Sims, Samantha Montes
Undergraduate Research Conference
Microplastics and their threat to marine environments are well known, but studies in freshwater environments are few and far between. Microplastics can be created by the breaking down of plastics or in the process of making plastics. They affect biological lifeforms in a multitude of ways, water temperature, permeability of the sediment. Pollution in Texas waterways have motivated groups like the Environmental Protection Agency, Trash Free Texas, and Environment Texas to get involved. The objectives of this study are two analyze Bonita and La Nana Bayou for microplastic presence and to educate and create awareness for Nacogdoches County on microplastics. …
The Effects Of Food Quality On Preference And Incurred Risk In White-Tailed Deer (Odocoileus Virginianus), Travis Perlman, Jacob Stanton
The Effects Of Food Quality On Preference And Incurred Risk In White-Tailed Deer (Odocoileus Virginianus), Travis Perlman, Jacob Stanton
Undergraduate Research Conference
An observational study was concluded in Nacogdoches County, Texas, to determine if free-range white-tailed deer (Odocoileus virginianus) could assess forage value. Multiple parameters were recorded to determine if individuals were willing to incur hight levels of risk as they sought to maximize their fitness, through dietary selection. Our results indicated that individuals were willing to incur higher levels of risk, in order to attain higher quality food items.
Habitat Preference Of Nitrophila Species, Kari Hugie
Habitat Preference Of Nitrophila Species, Kari Hugie
Undergraduate Research Conference
Nitrophila occidentalis and Nirophlia mohavensis are both members of the same Family and Genus, and they both are found in the Great Basin region. They are the only members of the Genus Nitrophila native to the United States. Nitrophila occidentalisflourishes in the Great Basin, but Nitrophila mohavensis is endangered and limited to a few populations. Habitat analysis was done to the two species using GIS (Geographical Information Systems) to gain some new insight on how to preserve this endangered species. A discrete difference in soil alkalinity preference was found, which may help in saving N. mohavensis.
