Using multidisciplinary approaches including metagenomics, metabolomics, and demographic analyses at four sites in Puerto Rico, the grantee will investigate the microbial profiles and...
This $187,290 National Science Foundation (NSF) Geosciences program (CFDA 47.050) Project Grant awarded to Florida International University (FIU) on December 1, 2023 aims to assess the impacts of the unprecedented 2023 marine heatwave on sponge communities in the Florida Keys coral reef ecosystem. The project has three key components: (A) field surveys to evaluate changes in sponge community structure, (B) mesocosm experiments examining the effects of elevated seawater temperatures and low...
This $282,231 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research into the ecological role of dead corals in ecosystem resilience and recovery from disturbance. The University of Florida will lead the five-year research program exploring how the physical structures left behind by dead corals influence patterns of biodiversity, ecosystem functions, and trajectories following shifts in habitat-forming species composition. Specifically, the...
The National Science Foundation awarded a $252,096 Project Grant to the University of Texas at Austin under the Geosciences program (CFDA 47.050) to conduct research quantifying energy fluxes on coral reefs from July 1, 2022 to June 30, 2024. The research will combine emerging technologies to examine how characteristics of small coral reef patches such as temperature, wave energy, architecture, and cryptic species assemblages shape reliance on different organisms to sustain larger reef fishes....
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) is funding a $783,165 research project titled "The Role of Diel Thermal Variability on Coral Performance" at Boston University. The project aims to understand how differences in diel thermal variability (DTV) influence the plasticity of coral thermal physiology and molecular function, focusing on the coral species Siderastrea siderea across sites in Bocas del Toro, Panama. The key...
This $228,683 National Science Foundation award under the Geosciences program (CFDA 47.050) supports research examining the role of cleaning symbiosis in transferring microbes on coral reefs. Specifically, the University of Miami will study how cleanerfish may serve as keystone regulators of microbial communities, enhancing diversity and transferring key species between clients. Researchers will also assess if cleanerfish facilitate reef resilience by aiding microbial recovery after...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $134,502 Project Grant to the Smithsonian Institution to conduct collaborative research on the changing trophic niches of large herbivorous fish on modern coral reefs. This study under the NSF Geosciences program (CFDA 47.050) aims to: (1) define the feeding behaviors and diets of herbivorous fishes on healthy coral reefs using traditional and cutting-edge techniques to quantify resource partitioning, and (2) determine...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research examining how chemical interactions between coral reef organisms, including corals, macroalgae, and encrusting algae, contribute to the success and biodiversity of economically important coral reef ecosystems. The $1,309,859 award to the Woods Hole Oceanographic Institution aims to advance the understanding of contact-free, chemically-based interactions between benthic organisms on...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to investigate the movement of key elements such as carbon, nitrogen, and phosphorus through coral reef fish communities in Belize. The $672,065 grant awarded on September 1, 2024 will fund research to uncover the origin and flow of these vital elements, as well as reveal relationships between benthic structural complexity and elemental fluxes across different spatial scales. The project...
This National Science Foundation project grant of $298,357 supports research investigating coral demographic processes and their interaction with climate change and local stressors to influence coral recovery trajectories. Funded under the Geosciences program (CFDA 47.050), the award will support analysis of time series coral size-frequency data across four Pacific regions to assess demographic rates following bleaching events and evaluate their importance in driving recovery dynamics....
This $199,676 National Science Foundation project grant supports research on the impact of the loss of the keystone sea urchin species Diadema antillarum on Caribbean coral reef community structure and function. The award period is from September 1, 2022 to August 31, 2023.
The grantee, Florida International University, will utilize innovative imaging tools and spatially explicit analyses to quantify fine-scale temporal changes in the community composition, size distributions, and spatial dispersion of D. antillarum, the dominant coral species Porites astreoides, and turf and macroalgae on reefs in Culebra, Puerto Rico. This will assess the hypotheses that the loss of the keystone urchin will impact overall reef community structure and trophic dynamics. Additionally, through a $49,000 subaward, the grantee will collaborate with Sociedad Ambiente Marino Inc. to facilitate fieldwork activities including boat and diving services, technical diving assistance, undergraduate research internships, and data collection. The research aims to advance understanding of top-down control of reef communities within the National Science Foundation's Geosciences program (CFDA 47.050).
