Highway Effects On Small Mammal Communities And Effectiveness Of A Deer-Vehicle Collision Mitigation Strategy, Silvia A. S. Rosa
Highway Effects On Small Mammal Communities And Effectiveness Of A Deer-Vehicle Collision Mitigation Strategy, Silvia A. S. Rosa
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
My work focused on the study of road effects and mitigation of negative impacts of roads on wildlife. Two different studies were conducted on Interstate 15, in southern Utah. My first study reported on road effects on small mammal communities. The results suggested that overall, there was no clear effect on small mammal populations relative to distance from the road. Most small mammal species did not appear to be negatively affected by the presence of the road. Instead, the road seemed to have either a neutral or a positive effect. The abundance and diversity of small mammals responded more markedly …

Many forest dwelling amphibians depend upon aquatic breeding habitats, making them susceptible to habitat changes. To determine if amphibian use of temporary pools occurred, 9 ponds were constructed in 3 forested areas on the MeadWestvaco Wildlife and Ecosystem Research Forest. Studies were conducted in 6 ponds during 2004, and all 9 in 2005 using drift fences. Trapped amphibians were measured and given a pond specific mark with visible implant elastomers. A significant difference was found between low and high elevation sites for juvenile R. sylvatica snout-to-vent length. No significant differences were found for soil, air or water temperatures between sites …
Foraging Behavior And Success Of Herons And Egrets In Natural And Artificial Wetlands, Henry Dewayne Mincey
Foraging Behavior And Success Of Herons And Egrets In Natural And Artificial Wetlands, Henry Dewayne Mincey
Electronic Theses and Dissertations
The southeastern United States has approximately 13.2 million hectares of wetland habitat, but these sensitive areas are subject to loss and degradation from draining and development. The effects, both positive and negative, that manipulation of these wetlands have on wildlife is still under study. In particular, there is a need to know whether artificial (mitigated) wetlands can serve as an appropriate substitute for the loss of natural wetlands. Therefore, I quantified the foraging behavior of herons and egrets (species that are dependent on wetlands for food) in natural and artificial wetlands in southeastern coastal Georgia and southern coastal South Carolina. …
