Acute And Chronic Effects Of Large-Vessel Anchoring On Coral Reef Communities Inside A Designated Commercial Anchorage, Lauren Waters May 2015

Acute And Chronic Effects Of Large-Vessel Anchoring On Coral Reef Communities Inside A Designated Commercial Anchorage, Lauren Waters

HCNSO Student Theses and Dissertations

Coral reefs provide economic and environmental services to millions of people as areas for recreation, sources of food, jobs, and shoreline protection; and are now under threat from multiple stresses (NOAA 2002). Anthropogenic impact from acute physical events such as commercial vessel grounding and anchor drags have been well documented throughout the world and southeast Florida. However little data exist on the chronic effects of large commercial vessels anchoring on reef resources. The Port Miami commercial anchorage was designated circa 1927 and was delineated over approximately 700 acres of reef resources. Anchorage use, benthic resources, and substrate composition were surveyed …

Mixed Ancestry And Admixture In Kauai's Feral Chickens: Invasion Of Domestic Genes Into Ancient Red Junglefowl Reservoirs, Eben Gering, M. Johnsson, P. Willis, T. Getty, D. Wright May 2015

Mixed Ancestry And Admixture In Kauai's Feral Chickens: Invasion Of Domestic Genes Into Ancient Red Junglefowl Reservoirs, Eben Gering, M. Johnsson, P. Willis, T. Getty, D. Wright

Biology Faculty Articles

A major goal of invasion genetics is to determine how establishment histories shape non‐native organisms' genotypes and phenotypes. While domesticated species commonly escape cultivation to invade feral habitats, few studies have examined how this process shapes feral gene pools and traits. We collected genomic and phenotypic data from feral chickens (Gallus gallus) on the Hawaiian island of Kauai to (i) ascertain their origins and (ii) measure standing variation in feral genomes, morphology and behaviour. Mitochondrial phylogenies (D‐loop & whole Mt genome) revealed two divergent clades within our samples. The rare clade also contains sequences from Red Junglefowl (the …

Marine & Environmental Sciences Faculty Articles

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosystem on Earth. Here we ask, using a unique data set of 530 forest plots, if the functions of storing and producing woody carbon are concentrated in a small number of tree species, whether the most abundant species also dominate carbon cycling, and whether dominant species are characterized by specific functional traits. We find that dominance of forest …

Through The Looking Glass Space To New Ways Of Knowing: A Personal Research Narrative, Gabrielle Brand Apr 2015

Through The Looking Glass Space To New Ways Of Knowing: A Personal Research Narrative, Gabrielle Brand

The Qualitative Report

This article describes how writing personal research narratives during my doctoral research journey challenged my role as a health professional and my personal beliefs and values in fundamental ways. In qualitative narrative inquiry, the reflexive account of the research experience is a key element in conducting ethical, rigorous, and meaningful forms of qualitative research. However, as a novice researcher, I was unprepared for the unlearning journey I experienced during the research process. This uncomfortable experience cut to the core of my identity by dismantling unexamined belief and value systems that lay dormant and hidden from my everyday consciousness as a …

Dissipation Rate Of Turbulent Kinetic Energy In Diel Vertical Migrations: Comparison Of Ansys Fluent Model To Measurements, Cayla Whitney Dean, Alexander Soloviev, Amy Hirons, Tamara M. Frank, J. D. Wood

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Recent studies suggest that diel vertical migrations of zooplankton may have an impact on ocean mixing, though details are not completely clear. A strong sound scattering layer of zooplankton undergoing diel vertical migrations was observed in Saanich Inlet, British Colombia, Canada by Kunze et al. (2006). In this study, a shipboard 200- kHz echosounder was used to track vertical motion of the sound scattering layer, and microstructure profiles were collected to observe turbulence. An increase of dissipation rate of turbulent kinetic energy by four to five orders of magnitude was measured during diel vertical migrations of zooplankton in one case …

A Comparative Study Of Microorganism Populations From Storm Water Treatment Areas And Select South Florida Locations, Sabina Joseph, Tamara Gali Apr 2015

A Comparative Study Of Microorganism Populations From Storm Water Treatment Areas And Select South Florida Locations, Sabina Joseph, Tamara Gali

Undergraduate Student Symposium

Nova Southeastern University (NSU) faculty and students are collaborating with Yale University to discover novel antibiotics produced by soil dwelling microorganisms. Pathogens responsible for many hospital-acquired infections are increasingly resistant to several antibiotics, driving the need for novel antibiotics. Antibiotic producing microorganisms present in soils should change with the concentrations of nutrients found in the soil or interstitial water in soils. To test this hypothesis, we screened for bacteria in samples from nutrient-poor soils in Davie and nutrient-rich soils in storm water treatment areas (STAs) in the Everglades. Soil samples were obtained, serially diluted and then plated on different media. …

A Novel Assay To Screen Drugs That Target Bacterial Type Iii Secretion Systems, Poorandai Sanicharran, Joanna Theodorou Apr 2015

A Novel Assay To Screen Drugs That Target Bacterial Type Iii Secretion Systems, Poorandai Sanicharran, Joanna Theodorou

Undergraduate Student Symposium

In recent years antibiotic resistant strains of bacteria have increasingly become a problem and pose a global threat. Several problematic 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 agood target for a novel antibiotic drug. The goal of this study is to develop an assay to screen for compounds that inhibit bacterial T3SSs. Y. enterocolitica uses a T3SS to cause gastroenteritis and will be utilized as the test organism. A disc …

An Algebro-Geometric Approach To Reverse Engineering The Lac Operon In E. Coli, Priscila Reyes, Ly Nguyen Apr 2015

An Algebro-Geometric Approach To Reverse Engineering The Lac Operon In E. Coli, Priscila Reyes, Ly Nguyen

Undergraduate Student Symposium

Discrete modeling of biological mechanisms such as the lac operon is crucial in giving us a thorough understanding of their function and the related control mechanisms. This, in turn, provides us with a deeper insight into the organisms that employ these biological mechanisms as a whole. In this work, we utilize certain techniques from algebraic geometry, such as Gröbner basis, to attain a polynomial representation of the lac operon in E. coli based on its required catalysts and environmental conditions. First, we construct a Boolean network and wiring diagram of the lac operon system in order to predict the status …

Antibacterial Of Natural Plant Extracts And Synthetic Compounds, Joanna Theodorou, Poorandai Sanicharran Apr 2015

Antibacterial Of Natural Plant Extracts And Synthetic Compounds, Joanna Theodorou, Poorandai Sanicharran

Undergraduate Student Symposium

Due to the growing problem of antibiotic resistant pathogens, development of new antimicrobials is a necessity. Biologically active plant extracts have the potential to combat the detrimental effects of pathogens without the risks sometimes associated with synthetic drugs. However, synthetic drugs have the benefit of having antibacterial activity and being well characterized. Mixing a natural plant extract with a synthetic compound could be an extremely beneficial and potent antibiotic. The purpose of the present study is to evaluate the antimicrobial efficacy of various classes of plants and synthetic compounds (2-Oxindole derivatives) against gram-negative and gram-positive bacteria. The antibacterial activity of …

Attitudes Of Rural Ecuadorians Toward Conservation Of Species And Environmental Education, Amanda Craig Apr 2015

Attitudes Of Rural Ecuadorians Toward Conservation Of Species And Environmental Education, Amanda Craig

Undergraduate Student Symposium

The exploration of people's attitudes in regard to other animal species with whom they co-exist in a shared ecosystem is a key element necessary for the improvement of local and regional conservation initiatives. In Ecuador, species such as the jaguar (Panthera Onca) require vast ranges of tropical rain forest and stretches of riverbank in order to survive in the wild. Increasing numbers of people share the forest with jaguars and other species. Habitat destruction and conversion, hunting and the potential lack of knowledge regarding the species’ ecological role continue to influence the conservation efforts of these threatened large …

Determining The Binding Of Phycocyanin To The Lncap Prostate Cancer Cells By Fluorescence Microscopy, Shona Joseph, Syed Hussain

Undergraduate Student Symposium

Phycocyanin (C-PC) is a natural pigment found in blue-green algae known as Spirulina. Since it has antiinflammatory properties, it was speculated that it might also be effective in treating cancers. Therefore, the main purpose of this study was to see whether C-PC would bind to the receptors on the cell membrane of cancer cells or penetrate the cell. Furthermore, the study was conducted to see whether the C-PC was able to bind to the membrane receptors with high or low affinity. For our binding and uptake experiments, LNCaP cells were used. After incubating with C-PC, the cells underwent multiple …

Don't Think It, Don't Do It: Controlling Executive Control, Karissa Delorme, Hannah Dean Apr 2015

Don't Think It, Don't Do It: Controlling Executive Control, Karissa Delorme, Hannah Dean

Undergraduate Student Symposium

Self-control involves the ability to control immediate impulses and desires. According to the ego depletion model, self-control is a limited resource. Many studies have found that participants who perform a selfcontrol task show impaired performance on subsequent executive control tasks, such as those measuring working memory and attention. In this study, we hypothesized that individuals who perform a self-control task would subsequently demonstrate poorer inhibitory control as measured in a Stroop and stop signal task. Participants were first given instructions to list their daily activities for five minutes as they either attempted to not think about a white bear (self-control …

Dsc And Tga Analysis On 3-Flowable Dental-Light Cured Restorative Composite, Samon Nazemian Apr 2015

Dsc And Tga Analysis On 3-Flowable Dental-Light Cured Restorative Composite, Samon Nazemian

Undergraduate Student Symposium

Since their introduction in 1996, dental-light cured flowable composites have been used as restorative materials for filling and repairing minimally invasive cavities. They are commonly used because they are insoluble, aesthetic, insensitive to dehydration, easy to manipulate, and reasonably inexpensive. Various brands advertise multiple advantages and are comprised differently. One property prior flowable composites exhibited was a significant polymerization shrinkage, which makes it unsuitable for occlusal wear. In this project, we analyzed the marginal shrinkage and stability of three different types of composites: CLEARFIL MAJESTY ES Flow, Genesis Flowable Light Cure Composite, and GrandioSO Heavy Flow. The composites were cured …

Dynamic Regulation Of Toxic Engineered Bacteria Prevents Learning In The Model Nematode Caenorhabditis Elegans, Olena Bracho, Cyril Manchery Apr 2015

Dynamic Regulation Of Toxic Engineered Bacteria Prevents Learning In The Model Nematode Caenorhabditis Elegans, Olena Bracho, Cyril Manchery

Undergraduate Student Symposium

Infections due to parasitic nematodes result in nearly 125,000 deaths annually. Strikingly, this rate remains nearly unchanged in the past 50 years likely owing to the fact that treatment options are either inefficient or inaccessible. Prior to infecting humans, most parasitic nematodes begin as larvae where they feed nearly exclusively on bacteria. This unique property may offer an opportunity to develop new biological control agents with the use of synthetic biology. Recently, we have engineered a bacterium, consisting of an attraction module and toxin module that lures in and kills nematodes, respectively, using the principles of synthetic biology to act …

Effects Of Functional Pattern Training On Hip And Knee Kinematics In Healthy Runners, Justin Romanes Apr 2015

Effects Of Functional Pattern Training On Hip And Knee Kinematics In Healthy Runners, Justin Romanes

Undergraduate Student Symposium

Faulty running biomechanics such as excessive hip internal rotation and knee valgus have been linked to overuse injuries in runners. Therapy interventions such as hip strengthening and mirrored gait retraining produce inconsistent results. The role of movement pattern training, predicated on Functional Movement Screen™ (FMS) performance has yet to be investigated. The objective of this study was to examine the effects of 6 weeks of functional pattern training on hip and knee kinematics in healthy, competitive runners with low FMS scores. 9 healthy adults [(males, n=6; age, 24.3±8.1 yrs; height, 1.78±0.09m; mass, 68.4±9.3kg)(females, n=3; age, 31±15.6 yrs; height, 1.70±0.06m; mass, …

Exhausted From Decision Fatigue: Do Personality Differences Influence Decision Making?, Basmatee Manohar Apr 2015

Exhausted From Decision Fatigue: Do Personality Differences Influence Decision Making?, Basmatee Manohar

Undergraduate Student Symposium

Making lots of decisions can result in what is known as decision fatigue. As past research has indicated, decision fatigue happens after contemplating choices while making decisions; this ultimately inhibits our ability to self-regulate and follow through on undesirable tasks. However, there is limited research that shows how the number of decisions people make impacts self-control. In this study, participants either rated how appealing food images looked or made a choice between two food images; the number of ratings/choices was either 10 or 30. Participants then engaged in the self-regulatory task of solving a difficult riddle. We hypothesized that participants …

Hypoxia Inducible Factor Mediated Human Angiotensinogen Gene Regulation, Nida Rizvi Apr 2015

Hypoxia Inducible Factor Mediated Human Angiotensinogen Gene Regulation, Nida Rizvi

Undergraduate Student Symposium

Alcohol usage is linked to increased blood pressure and fibrotic transformation of the liver. Angiotensinogen (AGT) is the source of Ang II which regulates blood pressure and participates in fibrotic transformation of the liver after the hepatocyte death. Ang II is produced from AGT by sequential action of renin followed by angiotensin converting enzyme. The levels of AGT are less than the MichaelisMenten constant of renin. Therefore, an increase in blood AGT levels would result into corresponding increase in Ang II levels that might affect blood pressure regulation and liver fibrogenic processes.

Alcohol metabolism by the liver produces oxidative stress …
