Quantifying parrotfish grazing on coral reefs : developing a metric for management and conservation / Principal Investigator, Deron Burkepile, Co-PI: Benjamin Ruttenberg.
"Herbivorous fish can benefit reef-building corals by controlling algae that compete with corals for space, but different species of herbivores have different and complementary impacts on benthic communities. Many herbivores are targeted in reef fish fish...
Soundscape ecology is an emerging field in both terrestrial and aquatic ecosystems, and provides a powerful approach for assessing habitat quality and the ecological response of sound-producing species to natural and anthropogenic perturbations. Little is...
Corals and Their Microbiomes Are Differentially Affected by Exposure to Elevated Nutrients and a Natural Thermal Anomaly
Nutrient pollution can increase the prevalence and severity of coral disease and bleaching in ambient temperature conditions or during experimental thermal challenge. However, there have been few opportunities to study the effects of nutrient pollution du...
Physical connectivity between Pulley Ridge and Dry Tortugas coral reefs under the influence of the Loop Current/Florida Current system
The Pulley Ridge and Dry Tortugas coral reefs are among the most pristine, but also fragile, marine ecosystems of the continental United States. Understanding connectivity processes between them and with surrounding shelf and deep areas is fundamental for...
Assisted sexual reproduction of Acropora cervicornis for active restoration on Florida’s Coral Reef
Given the rapid, global decline in the health and abundance of coral reefs, increased investments in restoration-based interventions -including asexual and sexual propagation- are being made by coral reef scientists at research institutions, but also at z...
Change and stasis of distinct sediment microbiomes across Port Everglades Inlet (PEI) and the adjacent coral reefs
Deep water ports are human built coastal structures that by definition welcome ship traffic and disturbance. Evidence is accumulating that enhanced port activities such as dredging or deepening have negatively affected nearby natural habitats. Port Evergl...
Saving the Last Unicorns: The Genetic Rescue of Florida’s Pillar Corals
As stony coral tissue loss disease (SCTLD) swept through the Florida Reef Tract, one of the most severely impacted species was the iconic pillar coral, Dendrogyra cylindrus. As the species’ population experienced a precipitous decline, a collaborative res...
Population trajectory and stressors of Acropora palmata sites in the Florida Keys
The decline of elkhorn coral, Acropora palmata, has been ongoing for decades, but the causes of decline and the resulting population status continue to be topics of study. Past efforts to categorize stressors have ranged from spatially and/or temporally f...
Differential survival of nursery‐reared Acropora cervicornis outplants along the Florida reef tract
In recent decades, the Florida reef tract has lost over 95% of its coral cover. Although isolated coral assemblages persist, coral restoration programs are attempting to recover local coral populations. Listed as threatened under the Endangered Species Ac...
Chemical and genomic characterization of a potential probiotic treatment for stony coral tissue loss disease
Considered one of the most devastating coral disease outbreaks in history, stony coral tissue loss disease (SCTLD) is currently spreading throughout Florida’s coral reefs and the greater Caribbean. SCTLD affects at least two dozen different coral species ...
Development and characterization of 148 SNP markers in the caribbean symmetrical brain coral Pseudodiploria strigosa
