A Population Genetic Investigation Of The Reticulated Flatwoods Salamander (Ambystoma Bishopi) On Eglin Air Force Base, Alexander S. Wendt Jan 2017

A Population Genetic Investigation Of The Reticulated Flatwoods Salamander (Ambystoma Bishopi) On Eglin Air Force Base, Alexander S. Wendt

Electronic Theses and Dissertations

The reticulated flatwoods salamander (RFS) is an endangered salamander with a unique life history. One of the largest known, best studied refuges for RFS is found on Eglin Air Force Base, and these RFS have been sampled and managed extensively since 2010. My thesis seeks to better understand RFS by using genetic techniques to address several unknowns, including: 1) determining the population structuring of RFS and the manageable units for species conservation, 2) estimating the size and status of populations, 3) understanding dispersal of RFS and factors that influence this, 4) exploring the breeding biology and recruitment patterns of RFS …


Vector Competence Of Aedes Sierrensis And Culex Pipiens Complex (Diptera: Culicidae) For Dirofilaria Immitis (Spirurida: Onchocercidae) In Northern California, Jeffrey Allan Kurosaka Jan 2017

Vector Competence Of Aedes Sierrensis And Culex Pipiens Complex (Diptera: Culicidae) For Dirofilaria Immitis (Spirurida: Onchocercidae) In Northern California, Jeffrey Allan Kurosaka

University of the Pacific Theses and Dissertations

Dirofilaria immitis Leidy (dog heartworm) is a life-threatening parasite transmitted by mosquitoes to domestic dogs. Endemic in the eastern United States, cases have become more prevalent over the last few decades. While prevalence in California is generally low, Lake and San Joaquin Counties have reported rates comparable to the East Coast at 3.73% and 0.71%(CAPC 2017), respectively. Aedes sierrensis is thought to be responsible for transmission in California, but in some cases, it exists in inadequate quantities and temporal ranges to explain parasite activity. Based on Huang et al. (2013) and Tran (2016), bloodfeeding patterns, and other vector criteria, Culex …


The Biological Stress Response In Bluegill Sunfish (Lepomis Macrochirus) To Variations In Environmental Temperature And Dissolved Oxygen Content., Monique Kellman Jan 2017

The Biological Stress Response In Bluegill Sunfish (Lepomis Macrochirus) To Variations In Environmental Temperature And Dissolved Oxygen Content., Monique Kellman

Honors College Theses

With the predicted increase in global water temperature and acute hypoxic episodes, knowledge of the effects these stressors can have on local aquatic life is extremely valuable. This study thereby quantified the change in metabolic rate in Bluegill sunfish, in response to increased temperature and low dissolved oxygen concentration, by utilizing intermittent flow respirometry. Both maximum metabolic rate (MMR) and resting metabolic rate (RMR) were determined in response to variations in dissolved oxygen content, specifically > 95% O2 and 40% O2. Additionally, three temperature treatment groups were established, with temperatures of 20, 25 and 30°C in order to …


An Analysis Of White-Tailed Deer, Odocoileus Virginianus, Killed In Deer Vehicle Accidents On Bulloch County, Ga Roadways, Mackenzie P. Payne 4003933 Jan 2017

An Analysis Of White-Tailed Deer, Odocoileus Virginianus, Killed In Deer Vehicle Accidents On Bulloch County, Ga Roadways, Mackenzie P. Payne 4003933

Honors College Theses

White-tailed deer, Odocoileus virginianus, are native to Georgia. With over 1.2 million individuals in the state, White-tailed deer have been implicated in a large number of motor vehicle collisions (ca. 1 million) each year. It is unknown, however, if deer are more likely to be killed: 1) if they are of particular ages (or classes), and 2) in areas with specific road characteristics. We addressed these two questions by collecting the remains of 20 White-tailed deer killed in deer vehicle collisions (“deer vehicle accidents” - DVAs) in Bulloch County, GA. When a deer was located, the road characteristics were …
