From Shelf to Shelf: Assessing Historical and Contemporary Genetic Differentiation and Connectivity across the Gulf of Mexico in Gag, Mycteroperca microlepis
Describing patterns of connectivity among populations of species with widespread distributions is particularly important in understanding the ecology and evolution of marine species. In this study, we examined patterns of population...
Sandy beaches are unique environments which offer billions of dollars’ worth of ecosystem services, including among others: storm protection, sediment storage and transport, habitat space for beach-dwelling and nesting species, nutrient...
In the uppermost millimeters of shallow submerged coastal sediments, photosynthesis by microalgae and cyanobacteria during daylight hours can cause oxygen supersaturation of sediment porewater, leading to bubble formation. In shallow...
Hardbottom habitats in the Big Bend Region of the Gulf of Mexico are the foundation for structure-forming species, such as corals and sponges. These structure forming communities (SFC) provide important ecological services; they serve as...
Skates exhibit a variety of manifestations of sexual dimorphism. However, this phenomenon has been poorly documented in deepwater species. New data on the sexual dimorphism of five species of deepwater skates from the North Atlantic...
The Florida Gulf of Mexico coast extends over both tropical and subtropical zones resulting in an intermingling of fauna typical to both zones. Cold winter water temperatures historically limited the distribution of many tropical species...
The Cownose Ray Rhinoptera bonasus is an opportunistic predator of benthic invertebrates and has had a long history of negative interactions with commercial shellfish industries. Most recently, Cownose Rays have been implicated in...
Polycyclic Aromatic Hydrocarbons (PAH) buried in sandy beaches of the northeastern Gulf of Mexico after the Deepwater Horizon accident posed a potential risk to environmental and human health. Therefore, concentrations and decay rates of...
Despite their simple appearance sponges are extremely diverse and complicated in their interactions with other organisms, and they are extremely difficult to identify to species. Often sponges of the same genus or body shape have very...
1. Research on rare and threatened species is often limited by access to sufficient individuals to acquire information needed to design appropriate conservation measures. 2. Using a combination of data from pop-up archival transmitting ...
Atlantic Bluefin tuna (ABFT) (Thunnus thynnus) spawn in the warm oligotrophic regions of the Gulf of Mexico (GoM) where zooplankton biomass is on average low and highly variable. Consequently, their larvae are thought to be highly...
Nitrate (NO3-) and uranium (U) are priority co-contaminants at U.S. Department of Energy (DOE) managed nuclear legacy waste sites, where nitric acid was extensively used to process uranium waste. This combination of a low pH and mixed...
Lytechinus variegatus, a widely known species of sea urchins, exist in different color morphs. Previous studies have shown that gamete recognition proteins are related to color expression in Echinoderms. In this study, crosses within and...
Fouling communities play a large role economically and ecologically around the world. They have harmful effects on transportation vessels, they are easily dispersed as invasive species, and certain fouling species such as oysters, ...
Sponges are an integral part of marine ecosystems, especially coral reefs, because they perform many functions necessary to keeping the ecosystems healthy. The most important of these functions is the filtration of the water around them....
In order to understand ecotour compliance to the marine mammal viewing guidelines it is essential to evaluate compliance as a holistic system. This requires not only assessing compliance levels to guidelines, but also assessing captain...
LLocal climate influences sea turtle hatching and emergence success with climatic extremes affecting embryonic development and hatchling emergence. Thus, it is crucial to understand how different climatic variables affect hatchling...
The purpose of this study was to determine the ability of the cownose ray, Rhinoptera bonasus (Mitchill, 1815), to manipulate oysters and clams, to test for relative prey preference, and to investigate whether susceptibility to cownose...
Zooplankton play an important role in global biogeochemistry and their secondary production supports valuable fisheries of the world’s oceans. Coupled physical-biogeochemical models (PBMs) provide a unique oceanographic research tool for...
This paper addresses the effects of increased temperature on the Red Tide dinoflagellate, Karenia brevis. A clonal strain of Karenia brevis was acclimated to the currently estimated increase in Gulf temperatures over a period of time...
Karenia brevis is a marine dinoflagellate commonly found in the Gulf of Mexico and important both ecologically and economically due to its production of the neurotoxin brevetoxin, which can cause respiratory illness in humans and...
The Deep-Sea Ecosystem: Assessment of the Biodiversity and Abundance of Deep-Water Fauna, in the Exuma Sound, Eleuthera, Bahamas, and the Northeastern Gulf of Mexico
The limited knowledge of the deep-sea is a paramount concern, affecting our ability to assess the overall health of the ocean’s ecosystem. Technology has made deep-sea fishing more accessible, but management plans cannot be implemented...
Despite being a known benthic biological hotspot and environmental ecotone, the DeSoto Canyon has hardly been characterized for its benthic diversity and community structure. Moreover, it is a known deposition and impact zone due to...
Foraging Ecology and Diet Selection of Juvenile Green Turtles (Chelonia mydas) in the Western Bahamas: Insights from Stable Isotope Analysis and Prey Mapping
Species’ foraging choices influences their somatic growth rates, age at maturity, and time spent in vulnerable early life stages. Thus, differences in population demographics are often attributed to variability either in diet type, ...
