A Retrospective Analysis Of Trends In Central Ohio Wildlife Health Using Records From A Wildlife Rehabilitation Facility, Rachel B. Dalton Apr 2016

A Retrospective Analysis Of Trends In Central Ohio Wildlife Health Using Records From A Wildlife Rehabilitation Facility, Rachel B. Dalton

Undergraduate Honors Thesis Projects

The analysis of records from wildlife rehabilitation facilities has shown great potential as a technique for monitoring health trends in local wildlife populations. We examined 45,668 records of animals admitted to a wildlife rehabilitation facility located in Ohio over a 10 year period (2005-2014). The objective was to examine how causes of admission for commonly admitted species may change over time and co-vary with seasonal patterns, with the goal of using fluctuations in wildlife admissions as a monitoring technique for population and ecosystem health. We assigned causes of admission to broad categories, such as “Collision with Non-Moving Object”, and a …


Cross-Sectional Analysis Of Salivary Cortisol And Cyathostome Infestation In Horses, Danielle L. Keating Jan 2016

Cross-Sectional Analysis Of Salivary Cortisol And Cyathostome Infestation In Horses, Danielle L. Keating

Undergraduate Honors Thesis Projects

With an increase in anthelmintic resistance and decreased efficacy of many commercial dewormers, understanding factors that contribute to parasite infestations in horses is integral to their management. The goal of this study was to look at the potential relationship between parasites and stress response by evaluating salivary cortisol levels and cyathostome egg shedding levels. Using a sample size of n = 200 horses from the state of Ohio, fecal and saliva samples were collected from each horse. Fecal egg counts were performed for each horse with a modified Stoll method, and saliva samples were tested with an enzyme-linked immunosorbent assay …


Determination Of Cyclic-Di-Gmp- Controlled Gene Expression In A Pharmacologically Important Bacterium, Morgan A. Stark Jan 2016

Determination Of Cyclic-Di-Gmp- Controlled Gene Expression In A Pharmacologically Important Bacterium, Morgan A. Stark

Undergraduate Honors Thesis Projects

The second messenger molecule cyclic dimeric GMP (c-di-GMP) regulates a myriad of processes in gram-negative bacteria. However, less is known about the roles it plays in gram-positive bacteria. Differential gene expression in three strains of the gram-positive bacterium, Streptomyces coelicolor, is being studied using RNA sequencing and Real Time PCR to gain insight into c-di-GMP signaling. The rmdA rmdB (regulator of morphology and development) double mutant was compared to the wild type strain known as MT1110. The rmdA and rmdB genes are needed for the formation of aerial mycelium, an important step in the life cycle of Streptomyces coelicolor (Hull …


Resurgence Of Acropora Corals On Mid Shelf Patch Reefs, Southwater Caye Marine Reserve, Central Belize, Jillian J. Keefer Jan 2016

Resurgence Of Acropora Corals On Mid Shelf Patch Reefs, Southwater Caye Marine Reserve, Central Belize, Jillian J. Keefer

Undergraduate Honors Thesis Projects

Acropora cervicornis (staghorn) and Acropora palmata (elkhorn) are ecologically important corals that grow quickly and provide topography and refuges for fish and invertebrates. Historically, Acropora was the most abundant coral in shallow patch reef zones in the Caribbean. During the 1980s, white band disease eliminated most Acropora causing a loss in rugosity and an increase of macroalgae on many reefs. Although Acropora remains rare throughout most of the Caribbean, this study documents its partial comeback and possible limiting factors in Southwater Caye Marine Reserve (SWCMR), Central Belize. Patch reefs in the reserve averaged 19% live coral cover with A. palmata …
