Using Ecological Diversity Analyses To Characterize The Availability Of Healthy Food And Socio-Economic Food Deserts, Annie Goyanes, J. Matthew Hoch

Marine & Environmental Sciences Faculty Articles

“Food deserts” are usually defined as geographic areas without local access to fresh, healthy food. We used community ecology statistics in supermarkets to quantify the availability of healthy food and to potentially identify food deserts as areas without a diverse selection of food, rather than a binary as to whether fresh food is present or not. We test whether produce diversity is correlated with neighborhood income or demographics. Abundance and diversity of fresh produce was quantified in supermarkets in Broward County, Florida, USA. Neighborhood income level and racial/ethnic makeup were retrieved from the U.S. Census and American Community Survey. Although …

Marine & Environmental Sciences Faculty Articles

Background

The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number of exploration licences issued by the International Seabed Authority. In the Indian Ocean, four licence areas exist, resulting in an increasing number of new hydrothermal vent fields and the discovery of new species. Most studies focus on active venting areas including their ecology, but the non-vent megafauna of the Central Indian Ridge and South East Indian Ridge remains poorly known.

In the framework of the Indian Ocean Exploration project in the German license area for seafloor massive …

Periodically Disturbing The Spatial Structure Of Biofilms Can Affect The Production Of An Essential Virulence Factor In Pseudomonas Aeruginosa, Rebecca J. Quinn, Ivana Barraza, Laura García-Diéguez, Camryn Pajon, Lauren E. Krausfeldt, Kerollos Ibrahim, Laura A. Enzinna, Morgan E. Thorn, Omar Tonsi Eldakar, Travis J. A. Craddock, Robert P. Smith

Biology Faculty Articles

Understanding the environmental factors that affect the production of virulence factors has major implications in evolution and medicine. While spatial structure is important in virulence factor production, observations of this relationship have occurred in undisturbed or continuously disturbed environments. However, natural environments are subject to periodic fluctuations, including changes in physical forces, which could alter the spatial structure of bacterial populations and impact virulence factor production. Using Pseudomonas aeruginosa PA14, we periodically applied a physical force to biofilms and examined production of pyoverdine. Intermediate frequencies of disturbance reduced the amount of pyoverdine produced compared to undisturbed or frequently disturbed conditions. …

Metabolomics Of Healthy And Stony Coral Tissue Loss Disease Affected Montastraea Cavernosa Corals, Jessica M. Deutsch, Olakunle A. Jaiyesimi, Kelly A. Pitts, Jay Houk, Blake Ushijima, Brian K. Walker, Valerie J. Paul, Neha Garg

Marine & Environmental Sciences Faculty Articles

Stony coral tissue loss disease, first observed in Florida in 2014, has now spread along the entire Florida Reef Tract and on reefs in many Caribbean countries. The disease affects a variety of coral species with differential outcomes, and in many instances results in whole-colony mortality. We employed untargeted metabolomic profiling of Montastraea cavernosa corals affected by stony coral tissue loss disease to identify metabolic markers of disease. Herein, extracts from apparently healthy, diseased, and recovered Montastraea cavernosa collected at a reef site near Ft. Lauderdale, Florida were subjected to liquid-chromatography mass spectrometry-based metabolomics. Unsupervised principal component analysis reveals wide …

The Design, Production And Validation Of The Biological And Structural Performance Of An Ecologically Engineered Concrete Block Mattress – A Nature Inclusive Design For Shoreline And Offshore Construction, Ido Sella, T. Hadary, A. Rella, Bernhard Riegl, Denise Swack, S. Perkol-Finkel

Marine & Environmental Sciences Faculty Articles

Over the past decade, the scientific community has studied, experimented, and published a notable body of literature on ecological enhancement of coastal and marine infrastructure (CMI). The Nature-Inclusive Design (NID) approach refers to methods and technologies that can be integrated into the design and construction of CMI to create suitable habitat for native species (or communities) whose natural habitat has been degraded or reduced. To examine the compliance of new environmentally sensitive technologies with structural requirements and fiscal restraints, while providing ecosystem and habitat value, this paper presents the findings of a structural-economical-biological analysis of ecologically engineered Articulated Concrete Block …

Stable Isotopes Used To Infer Trophic Position Of Green Turtles (Chelonia Mydas) From Dry Tortugas National Park, Gulf Of Mexico, United States, David C. Roche, Michael S. Cherkiss, Brian J. Smith, Derek A. Burkholder, Kristen M. Hart

Marine & Environmental Sciences Faculty Articles

Evaluating resource use patterns for imperiled species is critical for understanding what supports their populations. Here we established stable isotope (δ¹³C, δ¹⁵N) values for the endangered green sea turtle (Chelonia mydas) population found within the boundaries of Dry Tortugas National Park (DRTO), south Florida, USA. There is little gene flow between turtles sampled at DRTO and in other rookeries in Florida, underscoring the need to study this distinct population. Between 2008 and 2015 we collected multiple sample types (skin [homogenized epidermis/dermis], whole blood, red blood cells, plasma, carapace) from 151 unique green turtles, including …

Metaplasia Of Respiratory And Digestive Tissues In The Eastern Oyster Crassostrea Virginica Associated With The Deepwater Horizon Oil Spill, Deanne Roopnarine, Peter D. Roopnarine, Laurie C. Anderson, Ji Hae Hwang, Swati Patel

Biology Faculty Articles

Metaplasia is a well documented and deleterious effect of crude oil components on bivalved molluscs, including oysters. This reversible transformation of one cell type to another, is a common response to petroleum-product exposure in molluscs. It has been shown experimentally in previous work that eastern oysters (Crassostrea virginica) exposed to petroleum products will exhibit metaplasia of digestive tissues. Here we document for the first time that wild adult oysters inhabiting coastal waters in the northern Gulf of Mexico during and in the aftermath of the Deepwater Horizon oil spill (2010) exhibited metaplasia in both ctenidia and digestive epithelia …

The Link Between Diabetes Mellitus And Tau Hyperphosphorylation: Implications For Risk Of Alzheimer's Disease, Amy L. Hobday, Mayur S. Parmar

HPD Articles

Diabetes mellitus (DM) is characterized by hyperglycemia caused by a lack of insulin, insulin resistance, or both. It is associated with the development of secondary complications resulting in several comorbidities. Recent studies have revealed an increased risk of developing cognitive dysfunction or dementia in diabetes patients. Diabetes mellitus is considered a risk factor for many neurodegenerative diseases, including Alzheimer's disease (AD). There is increasing evidence to support a link between DM and AD. Studies have shown the dysfunction of insulin signaling in the brain, resulting in increased tau protein phosphorylation (hyperphosphorylation), a hallmark and biomarker of AD pathology, leading to …

Validation Of A Single Channel Eeg For The Athlete: A Machine Learning Protocol To Accurately Detect Sleep Stages, Kayla Thompson, Kamil Celoch, Frankie Pizzo, Ana I. Fins, Jaime Tartar

Journal for Sports Neuroscience

There is a large and growing movement towards the use of wearable technologies for sleep assessment. This trend is largely due to the desire for comfortable, burden free, and inexpensive technology. In tandem, given the competitive nature of professional athletes enduring high training load, sleep is often jeopardized which can result in adverse outcomes. Wearable devices hold the promise of increasing the ease of monitoring sleep in athletes which can inform health and recovery status, as well as aid performance optimization. However, wearable devices typically lack sufficient validity to assess sleep – and especially sleep stages. To address this concern, …

A Systematic Review Of Parasites Found Within Selected Teleost Fishes Of The South Florida Hermatypic Coral Reef Tract, Blake A. Roberts

All HCAS Student Capstones, Theses, and Dissertations

This report is a synthetic survey of published accounts of 43 reef-associated fish species and their parasites from the east coast of North America, the Caribbean Sea, Gulf of Mexico, and regions adjacent to the south Florida reef tract. To date, no comprehensive host-parasite list is available for this region, although comparable reviews from other regions have played a vital role in the fields of parasitology and fish ecology, providing valuable guidance on sampling locations, available host fishes inhabiting the region, and inventories of parasites likely to be found infecting these host species. This systematic review of teleost host fish …

Mako: NSU Undergraduate Student Journal

Eumaeus atala is an endangered tropical butterfly native to the Caribbean and some parts of Florida, USA. Following population reductions primarily due to habitat loss, E. atala populations are now increasing due to conservation efforts of its cycad host plants, especially Zamia integrifolia (coontie). The purpose of this study was to observe, document, and measure the population of wild E. atala on the Ft. Lauderdale, Florida campus of Nova Southeastern University where landscaping use of host plants supports a natural population of E. atala. Forty-four host plants located in two different sites were observed for 14 weeks. One site …

The Age And Growth Of The Yellow Stingray (Urobatis Jamaicensis) In Southeast Florida, Jessica Schieber

All HCAS Student Capstones, Theses, and Dissertations

The yellow stingray, Urobatis jamaicensis (Cuvier 1816), is a coastal species that has limited known life-history information, especially regarding their age and growth patterns. Age estimates were assigned by counting band-pairs deposited on the vertebral centrum of stingrays caught between 2003 and 2019 (n = 195). Marginal increment analysis of different size classes was used to validate age estimates, with the largest class having verified annual band deposition (ANOVA, F(9,7), P = 0.029). Age estimates ranged between females, and rates, but females attained larger sizes with the largest observed DW being 241-mm and 216-mm for females and males, respectively. …

The Distribution, Composition, And Management Of Drifting Fish Aggregating Devices (Dfads) In The North Atlantic Ocean, Erin E. Kimak

All HCAS Student Capstones, Theses, and Dissertations

Drifting Fish Aggregating Devices (dFADs) are a gear accessory utilized on a global scale by commercial fishers to increase catch size and efficiency of target pelagic fishes such as tuna and dolphinfish. Despite their widespread use, there are few scientific estimates of the total number of abandoned or beached dFADs in the Atlantic Ocean and Caribbean Basin or the compliance of dFAD use with t-RFMO recommendations. Previous studies have utilized the modeled drift trajectories of dFADs to predict beaching probability and location, but this study is the first of its kind, analyzing true beaching events. This study identifies the beaching …

Genetic Population Dynamics Of The Critically Endangered Scalloped Hammerhead Shark (Sphyrna Lewini) In The Eastern Tropical Pacific Ocean, Sydney P. Harned

All HCAS Student Capstones, Theses, and Dissertations

The scalloped hammerhead shark, Sphyrna lewini, is a Critically Endangered, migratory species known for its tendency to form large aggregations of mostly adult females, especially in the heavily-fished Eastern Tropical Pacific (ETP) Ocean. This species forms iconic, visually spectacular, seasonal aggregations in the northern Galápagos Islands, and it is hypothesized based on telemetry studies that pregnant females from these aggregations migrate to mainland coastal nurseries for parturition. This study investigated the population genetic dynamics of the scalloped hammerhead across most of its coastal and offshore distribution (Mexico to Ecuador) in the ETP, focusing on young-of-the-year animals sampled from nursery …

Most importantly, researchers in the STEM fields directed their attention and expertise to help mitigate virus transmission, treat patients, …

Short- And Long-Term Effectiveness Of Coral Disease Treatments, Karen L. Neely, Colin P. Shea, Kevin A. Macaulay, Emily K. Hower, Michelle A. Dobler

Marine & Environmental Sciences Faculty Articles

Since 2014, stony coral tissue loss disease (SCTLD) has led to large-scale mortality of over 20 coral species throughout the Florida Reef Tract. In 2019, in-water disease intervention strategies were implemented to treat affected corals. Two treatment strategies were employed: (1) topical application of an amoxicillin paste directly to disease margins, and (2) application of a chlorinated epoxy to disease margins as well as an adjacent “disease break” trench. Effectiveness of treatments on 2,379 lesions from 725 corals representing five species was evaluated using mixed effects logistic regression models which demonstrated substantially greater effectiveness of amoxicillin compared to chlorine-treated lesions …

Sexual Conflicts In Sand Tiger Sharks Carcharias Taurus (Rafinesque, 1810) In An Artificial Environment, Elizabeth Claus, Alan Henningsen, Mahmood Shivji, Bradley Wetherbee

Biology Faculty Articles

Understanding reproductive behaviours and the environmental conditions that facilitate reproduction is important for successful reproduction in managed care. Complex reproductive behaviours have been observed in both aquarium and free-ranging elasmobranchs. Sexual conflicts, including pre-copulatory behaviours in sand tiger sharks Carcharias taurus in managed care have been previously documented. This study reports observations that corroborate the previous accounts of reproductive behaviours as well as describing novel consexual conflicts between males and detailing the male dominance hierarchy in six sand tigers at the National Aquarium. The observations suggest that male behaviours are not strictly pre-copulatory, as consexual male conflicts occurred to the …
