A Systematic Study Of The Highly Endemic Spider Beetle Fauna (Coleoptera: Ptinidae: Ptininae) Found In The Coastal Deserts Of Perú, Marlena Askren
A Systematic Study Of The Highly Endemic Spider Beetle Fauna (Coleoptera: Ptinidae: Ptininae) Found In The Coastal Deserts Of Perú, Marlena Askren
Masters Theses & Specialist Projects
Spider beetles are small, often flightless insects that occur in hyperarid environments around the world. They exhibit interesting morphology and behavior that allows them to conserve water they obtain from plant material, dung, and other detritus. One hyperarid region in which they are found is the Pacific coast of Perú and northern Chile. The Sechura Desert, Peruvian Coastal Desert, and Atacama Desert make up the arid coast where spider beetles occur from north to south. Through multiple years of field work and museum collections, populations of spider beetles were found along the coast in isolated pockets of vegetation, separated by …
Body Shape Diversification Of Pecos Pupfish (Cyprinodon Pecosensis) On Varying Habitats As Evaluated By Geometric Morphometrics, Qianna Xu
Masters Theses & Specialist Projects
During the 19th and 20th centuries, alterations to the Pecos River in New Mexico and Texas, USA due to anthropogenic activities, including damning and river channelization, vast water extraction for irrigation, as well as pollution of associated habitats, have greatly impacted the fish fauna within the drainage. One of the endemic fish species, the Pecos pupfish (Cyprinodon pecosensis), might be the most affected. Historically abundant and widespread large populations have been disrupted and became a series of small isolated subpopulations that persist at a few highly fragmented habitats restricted to a small area in southern New Mexico. The connectivity among …

The Effects Of Drought On Diets Of Apex Predators In The South African Lowveld Inferred By Fecal Hair Analysis, Shelby Wade
Mahurin Honors College Capstone Experience/Thesis Projects
To properly manage offtake quotas and conservation efforts, Balule Nature Reserve (South Africa) instituted a study in 2014 to determine prey species selection by megapredators. In 2015, Balule Nature Reserve received about 190 mm less rainfall between the months of January and June than in 2014 (116 mm less than average). This study compares the diets of lions and hyaenas between 2014 and 2015. Prey species consumed were determined by fecal analysis, and results were compared to prey availability. Sixteen, 1 km2 plots were chosen from the 400 km2 Reserve. Between June and August 2015, we walked three, 1 km …
