Anthropogenic climate change is altering temperature regimes for coastal marine fishes. However, given that temperature changes will not occur in isolation of other stressors, it is necessary to explore the potential consequences of stress on the thermal tolerances and preferences of tropical marine fish in order to understand the thresholds for survival,(More)
Knowledge of the swimming energetics and thermal ecology of sub-tropical and tropical coastal species is extremely limited, yet this information is critical for understanding animal–environment relationships in the face of climate change. Using the ecologically and economically important sportfish, bonefish (Albula vulpes), we determined the critical(More)

We present herein a patient with multiple medical illnesses, marked weight loss, and chronic anemia. Cytologic studies of his bone marrow revealed hypocellularity and gelatinous transformation (GTBM). The latter is a disorder of the hematopoietic system commonly occurring in chronically ill patients and is associated with various hematologic abnormalities.(More)
Climate change due to anthropogenic activity will continue to alter the chemistry of the oceans. Future climate scenarios indicate that sub-tropical oceans will become more acidic, and the temperature and salinity will increase relative to current conditions. A large portion of previous work has focused on how future climate scenarios may impact(More)
Individual variation in the endocrine stress response has been linked to survival and performance in a variety of species. Here, we evaluate the relationship between the endocrine stress response and anti-predator behaviors in wild checkered puffers (Sphoeroides testudineus) captured at Eleuthera Island, Bahamas. The checkered puffer has a unique and easily(More)
Bonefish Albula vulpes (n = 7) exercised to exhaustion and air exposed for 1 min as part of a catch-and-release angling event were found to excrete both ammonia and urea, but cortisol and lactate were below detectable levels. Urea made up a greater proportion of total nitrogen excretion from these fish at all time points following an angling event. When(More)
Catch-and-release angling is growing as a tool for the conservation of fish stocks because it assumes that the impacts of angling are negligible. However, many studies have shown that catch-and-release can be stressful to the fish and even result in mortality. Bonefishing represents a popular catch-and-release fishery in the tropics and subtropics, with(More)
Development on Grand Bahama in the Bahamian Archipelago during the 1950’s to 1970’s resulted in substantial changes to the island’s geography. Hawksbill Creek, which potentially served as a natural migration route for fish from the north side to the south side of the island, was severed and replaced by a man-made canal called the Grand Lucayan Waterway(More)
As human populations continue to expand, increases in coastal development have led to the alteration of much of the world's mangrove habitat, creating problems for the multitude of species that inhabit these unique ecosystems. Habitat alteration often leads to changes in habitat complexity and predation risk, which may serve as additional stressors for(More)
