Electronic Theses and Dissertations
MacGillivray's Seaside Sparrow (Ammodramus maritimus macgillivraii) is a coastal marsh species sensitive to habitat alteration and threatened by coastal wetland loss. Data on seaside sparrow distribution, breeding success, and critical habitats are lacking in South Carolina. To better understand the demographics and incubation behavior of the species, I monitored breeding success, densities, song output, and presence of predators at three 7-hectare plots at the densest known population in the state. I also placed temperature data-loggers in a subset of nests to discern any links between incubation behavior and nest fate. Densities varied from a low of 5 birds/ha in a …

Mitochondrial Dna Inheritance In Bivalves: A Comparative Study Involving The Unique System Of Doubly Uniparental Inheritance, Sarah Heishman
Honors Theses
A comparative study of Doubly Uniparental Inheritance (DUI) in the bivalve mollusks Mytilus edulis and Geukensia demissa has yielded unanticipated results. Around the world, it has been reported that members of the taxonomic family Mytilidae (along with the families of Unionidae and Veneridae) consistently exhibit DUI. However, the hard-to-place Geukensia demissa, which is a member of this family, has had varying reports of its DUI status. Most reports involving G. demissa vary with the location in which it is being studied, which prompts more questions than it answers. Due to many months of unsuccessful DNA purification attempts, sequencing and an …
