Sea Turtle Conservation: Reviewing The Efficacy Of Land- And Sea-Based Management Strategies For Loggerhead (Caretta Caretta) And Leatherback (Dermochelys Coriacea) Sea Turtles, Glenn D. Goodwin

HCNSO Student Capstones

As cosmopolitan species, loggerhead and leatherback turtles are confronted with a multitude of threats as they progress through their respective life stages. These range from depredation and poaching of eggs, hatchlings, and females on nesting beaches, to incidental hooking in pelagic longline fisheries and capture in trawl fisheries. Some threats are species specific on regional scales, though most impact both species. To confront these threats, various conservation strategies have been developed and implemented, including monitoring and caging of nests and changes to hook shape and trawl design. Here, current conservation methods are presented and discussed on a global scale for …

A Comparison Of Qualitative And Quantitative Data Collection Techniques To Assess Mapping Accuracy In The Florida Keys, Ian K. Rodericks

HCNSO Student Theses and Dissertations

Benthic habitat maps provide the spatial framework for many research science and management activities in coastal areas such as coral-reefs. Accuracy, the degree to which information on a map matches true or accepted values, of benthic habitat maps is important because often times the map will be used in decision-making processes about how we manage our marine resources. It is critical that some measure, such as the accuracy, of the map be known in order to give a sense of how the overall map portrays the seascape. This study compared the accuracy in the following map classes; major structure, major …

The Asian arowana (Scleropages formosus), one of the world’s most expensive cultivated ornamental fishes, is an endangered species. It represents an ancient lineage of teleosts: the Osteoglossomorpha. Here, we provide a high-quality chromosome-level reference genome of a female golden-variety arowana using a combination of deep shotgun sequencing and high-resolution linkage mapping. In addition, we have also generated two draft genome assemblies for the red and green varieties. Phylogenomic analysis supports a sister group relationship between Osteoglossomorpha (bonytongues) and Elopomorpha (eels and relatives), with the two clades together forming a sister group of Clupeocephala which includes all the remaining …

A Tale Of Two Theories: Using An Engineered Strain Of E. Coli To Bridge The Gap Between Quorum Sensing And Diffusion Sensing, Cortney E. Wilson Apr 2016

A Tale Of Two Theories: Using An Engineered Strain Of E. Coli To Bridge The Gap Between Quorum Sensing And Diffusion Sensing, Cortney E. Wilson

HCNSO Student Theses and Dissertations

Cooperation is a trait that is found at all levels of biological organization. Interestingly, cooperation appears to occur in bacteria that produce small, easily diffusible molecules called autoinducers. To understand why bacteria produce these autoinducers, the scientific community has focused on one predominant theory called quorum sensing. Under this theory, bacteria produce autoinducers so they can sense the density of the population. Once a sufficiently high population density is reached, autoinducers initiate the production of a costly gene product that serves to benefit the population. In contrast, a competing theory called diffusion sensing suggests that autoinducers are used by the …

Pregnancy And Childbirth Practices Among Immigrant Women From India: “Have A Healthy Baby”, Rama Cousik, M. Gail Hickey

The Qualitative Report

In India, practices relating to pregnancy, childbirth and child development have been rooted in cultural beliefs and traditions that are based on knowledge contained in ancient Indian texts. Many Indians residing across the globe continue to observe these practices. Some may find it challenging to do so when they are residing abroad, away from familiar surroundings and separated from their extended families. A small body of research exists that shows that migrant Indian women do observe traditional maternal practices based on cultural beliefs, but there is a need to learn more about how this knowledge is acquired, disseminated and preserved. …

Marine & Environmental Sciences Faculty Articles

Background:  Acropora cervicornis, a threatened, keystone reef-building coral has undergone severe declines (>90 %) throughout the Caribbean. These declines could reduce genetic variation and thus hamper the species’ ability to adapt. Active restoration strategies are a common conservation approach to mitigate species' declines and require genetic data on surviving populations to efficiently respond to declines while maintaining the genetic diversity needed to adapt to changing conditions. To evaluate active restoration strategies for the staghorn coral, the genetic diversity of A. cervicornis within and among populations was assessed in 77 individuals collected from 68 locations along the Florida Reef …

Population Fluctuation Of The Nodular Coral Psammocora Stellata In The Galápagos Islands, Ecuador: An Indicator Of Community Resilience And Implications For Future Management, Kathryn Brown

HCNSO Student Theses and Dissertations

Corals are experiencing a worldwide decline in abundance and diversity. Reasons for this include anthropogenic impacts and associated changes to environmental conditions, including global climate change. Increasing atmospheric CO2 levels lead to a coordinated increase in sea surface temperatures and decrease in oceanic pH. Warming events associated with El Niño-Southern Oscillation (ENSO) amplify the impacts of steadily increasing temperatures. For example, coral communities in the Galápagos Islands experienced mortality rates of up to 95-99% during severe ENSO warming in 1982-1983. Persisting through such extreme conditions imposes additional challenges to survival in already marginal environments for coral growth and development …

A Novel Approach To Gait Retraining In Competitive Runners, Kourtney Kostzer, Brittany Calaluca Apr 2016

A Novel Approach To Gait Retraining In Competitive Runners, Kourtney Kostzer, Brittany Calaluca

Undergraduate Student Symposium

Running is a popular fitness activity with health benefits. However, running related injuries are common and reoccurring. These injuries are linked to faulty biomechanics such as excessive hip adduction (HADD), hip internal rotation (HIR), knee valgus (KVAL), and contralateral pelvis drop (CPD). Therapists attempt to retrain gait using biofeedback and muscle strengthening with mixed results. Functional movement pattern (FMP) training is a novel intervention that corrects underlying FMPs (stepping, squatting). The purpose of this study was to evaluate the effectiveness of a 6-week FMP corrective program to retrain running gait. We used paired t-tests to evaluate changes in peak motion …

A Novel Method To Screen Drugs That Target Bacterial Type Iii Secretion Systems, Poorandai Shivbaran Apr 2016

A Novel Method To Screen Drugs That Target Bacterial Type Iii Secretion Systems, Poorandai Shivbaran

Undergraduate Student Symposium

Antibiotic resistant strains of bacteria pose a global health threat. Several pathogenic bacteria utilize a type III secretion system (T3SS) to infect their host. T3SSs are needle-like appendages on the bacteria, used to inject the host cell with toxins, which disrupts the cell’s defense. Hence, the T3SS would be a good target for new antibiotic drugs. The goal of this study was to develop a novel method to screen for compounds that inhibit bacterial T3SSs. Yersinia pestis uses a T3SS to cause the bubonic plague and was utilized as the test organism. A disk diffusion assay on Magnesium Oxalate Agar …

Adenosine Deaminase Associates With Self-Reported State Anxiety And Evening Melatonin Levels, Franklin Hiffernan Apr 2016

Adenosine Deaminase Associates With Self-Reported State Anxiety And Evening Melatonin Levels, Franklin Hiffernan

Undergraduate Student Symposium

Increased adenosine levels throughout the day promote sleepiness; this chemical is broken down by the enzyme adenosine deaminase (ADA). A single nucleotide polymorphism (SNP) in the ADA gene (rs73598374) has been shown to affect sleep regulation. This ADA SNP substitutes a G allele with an A allele, thus reducing ADA enzymatic activity and resulting in higher adenosine levels. Consistent with the idea that adenosine promotes sleepiness, carriers of the A allele show elevated sleep pressure and increased EEG measures of deep (delta) sleep. Aside from these findings, the extent to which lower ADA enzymatic activity is associated with the homeostatic …

Assessing Migration Ability And Behavior Of Small Fish In The Everglades, Chelsea Jeffers, Emily Harrington, Michele Lamartina, Dominique Olesen, Deoraj Ramsaran, Rachel Tonia

Undergraduate Student Symposium

Small fish are important to the Everglades as a food source for wading birds. Fish migrate to and from wetlands that dry annually, where predation is greatest. It is unclear what factors induce this migration. Our goals are to understand what influences migration, including the fishes’ personality and parasite infection. Our hypotheses test whether personality and parasite load differ among species, by region, or between the dry and wet seasons. We sampled the fish communities at sites that dry annually and sites that do not to identify relative abundances. The most abundant fishes were brought to the lab. We filmed …
