We evaluated the impact of shoreline dynamics on fringing vegetation density at mid- and low-marsh elevations at a high-energy site in the northern Gulf of Mexico. Particularly, we selected eight unprotected shoreline stretches (75 m each) at a historically eroding site and measured their inter-annual lateral movement rate using the DSAS method for three consecutive years. We observed high inter-annual variability of shoreline movement within the selected stretches. Specifically, shorelines retrograded (eroded) in year 1 and year 3, whereas, in year 2, shorelines advanced seaward. Despite shoreline advancement in year 2, an overall net erosion was recorded during the survey …

Most animal–microbe symbiotic interactions must be advantageous to the host and provide nutritional benefits to the endosymbiont. When the host provides nutrients, it can gain the capacity to control the interaction, promote self-growth, and increase its fitness. Chlorella-like green algae engage in symbiotic relationships with certain protozoans, a partnership that significantly impacts the physiology of both organisms. Consequently, it is often challenging to grow axenic Chlorella cultures after isolation from the host because they are nutrient fastidious and often susceptible to virus infection. We hypothesize that the establishment of a symbiotic relationship resulted in natural selection for nutritional and metabolic …
Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Student Scholar Symposium Abstracts and Posters
One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …
Bacteriophages That Can Lyse Antibiotic Resistant Bacteria, Michael Monaco
Bacteriophages That Can Lyse Antibiotic Resistant Bacteria, Michael Monaco
Honors Theses
A Klebsiella pneumoniae bacteriophage was isolated from waste water and purified over multiple rounds of plaque removals and serial titrations. This bacteriophage was imaged in a transmission electron microscope and then tested with selected antibiotics for effectiveness in reducing optical density of K. pneumoniae colonies. The phage was shown to have an increased effectiveness in reducing the optical density when used together with an antibiotic that the bacteria was susceptible to.

"Patterns In The Abundance Of Benthic Algae In Streams", Courtney Wright
Honors Theses
Benthic, microscopic algae are the main drivers of primary productivity in streams. The relationship between the abundance and productivity of benthic algae in streams and lakes and the availability of limiting nutrients, especially soluble reactive phosphorus (SRP), has been extensively studied (reviewed in Allan and Castillo 2007, Larned 2010). However, nearly all of this research has been conducted on the periphyton assemblage found on hard substrates (e.g., stones, wood), while very little work has addressed the factors affecting the abundance of epipelic algae (i.e., the algae associated with depositional (soft) sediments such as sands and silts). One of the few …
Mislabeling Of Commercial Atlantic Cod (Gadus Morhua) Products In Spain, Joshua Helgoe
Mislabeling Of Commercial Atlantic Cod (Gadus Morhua) Products In Spain, Joshua Helgoe
Theses and Dissertations
The mislabeling of commercial fish products is a pervasive, worldwide problem. Most consumers of seafood are unaware this issue directly affects them and can even have negative impacts on their health. Mislabeling occurs when a product’s label is inconsistent with its content. Although mislabeling can be unintentional, deliberate mislabeling is a more common trend to increase profits and/or bypass fishing regulations - a form of economic fraud. Unfortunately, oversight, enforcement, and research are vastly insufficient in relation to the global scale of the problem. In order to add to the small knowledge base on European mislabeling rates, determine if overfished …
