Dung Beetle (Scarabaeinae) Diversity Of The Highest Elevation In West Africa: The Nimba Mountain Range, Jacob Bowen
Dung Beetle (Scarabaeinae) Diversity Of The Highest Elevation In West Africa: The Nimba Mountain Range, Jacob Bowen
Mahurin Honors College Capstone Experience/Thesis Projects
The Nimba Mountain Range in Guinea, Ivory Coast, and Liberia is within the Upper Guinean Forests, a critical biodiversity hotspot highly threatened by various human activities. The region is home to many endemic species including the viviparous Nimba toad, Nimba otter-shrew, and the discrete Bossou chimpanzee population. Dung beetles can act as a focal taxon from which extrapolation to the diversity of other taxa and ecosystem health can be made. Elevational trends in dung beetle diversity were investigated on the Nimba Mountain Range and in the nearby Bossou Chimpanzee reserve in Guinea. Dung beetle species diversity surveys aimed to document …
Analysis Of Seed Preference Trials Of Red Veld Rats And Smith's Bush Squirrels And Trap Effectiveness In The Lowveld Of South Africa, Brooke A. Barber
Analysis Of Seed Preference Trials Of Red Veld Rats And Smith's Bush Squirrels And Trap Effectiveness In The Lowveld Of South Africa, Brooke A. Barber
Mahurin Honors College Capstone Experience/Thesis Projects
Large tree species in South Africa face reproductive decline, especially older trees that provide ecosystem connectivity. Management of Balule Nature Reserve, an extensive private nature reserve in South Africa, wanted to investigate the roles rodents play in the recruitment and survival of select tree species. Two large tree species of concern, marula (Sclerocarya birrea) and knobthorn acacia (Acacia nigrescens) are dominant, habitat providers and red bushwillow (Combretum apiculatum) is a smaller and more common, prolific seed producer. I investigated whether rodents, specifically red veld rats and Smith’s bush squirrels, may play a detrimental role …
Landscape Genetics Of The Endangered California Tiger Salamander (Ambystoma Californiense) In The Los Vaqueros Watershed, Ryan Neal Vincent
Landscape Genetics Of The Endangered California Tiger Salamander (Ambystoma Californiense) In The Los Vaqueros Watershed, Ryan Neal Vincent
Mahurin Honors College Capstone Experience/Thesis Projects
Genetic diversity is essential for maintaining healthy biological systems, and dispersal-mediated gene flow increases genetic diversity by introducing new alleles to a gene pool. Populations that frequently experience gene flow will show characteristic similarities in allele frequencies. Measuring genetic diversity among many populations across a landscape has proven to be a powerful approach for assessing the ways that habitat discontinuities may affect patterns of gene flow, and in turn, influence allele frequencies and population dynamics. This study examines the landscape-level population genetic structure of the California tiger salamander, Ambystoma californiense, within the Los Vaqueros Watershed of Contra Costa County, …
