Distribution And Soil Characteristics Associated With The Neches River Rose-Mallow (Hibiscus Dasycalyx), Morgan E. Langlinais
Distribution And Soil Characteristics Associated With The Neches River Rose-Mallow (Hibiscus Dasycalyx), Morgan E. Langlinais
Electronic Theses and Dissertations
The Neches River rose-mallow, Hibiscus dasycalyx, is a rare herbaceous perennial endemic to East Texas. The threatened, obligate wetland species is currently at risk of being lost in the wild due to habitat loss, encroachment of nonnative and native plant species, and hybridization with two other Hibiscus congeners, Hibiscus laevis and Hibiscus moscheutos. Known locations of each of the three Hibiscus species were used to measure select soil characteristics and habitat variables associated with each of the rose-mallows. H. dasycalyx was concluded to be associated with more fertile soils and slightly more canopy coverage than H. laevis and …
Effects Of Excessive Soil Phosphorus Accumulation On Loblolly Pine (Pinus Taeda L.) Seedlings, Hannah C. Bays
Effects Of Excessive Soil Phosphorus Accumulation On Loblolly Pine (Pinus Taeda L.) Seedlings, Hannah C. Bays
Electronic Theses and Dissertations
Many landowners in East Texas apply poultry litter to pastures as a source of nitrogen (N) for forage crops. After many years of repeated poultry litter application, soils can accumulate extremely high extractable phosphorus (P) concentrations, sometimes over 1000 mg kg-1 of plant available P. Landowners report the conversion of these pastures to loblolly pine (Pinus taeda L.) plantations is often problematic, with poor seedling survival and abnormal tree growth. This study was conducted to assess the effects of excessive soil phosphorus on loblolly pine seedlings. An outdoor pot study was conducted using bare root seedlings and triple …
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 …
