Understanding Coral Ecosystem Connectivity in the ...

We investigated the role that the mesophotic coral ecosystems of Pulley Ridge (off the southwest coast of Florida) played in replenishing key coral, sponge, algal, and fish species in the ...

Using Data on Reef Fish Foraging in Seagrass Beds ...

No-take marine reserves are critical tools for protecting reef fishes and should include all habitats the fishes use. However, we have little information about reef fish foraging in seagrass beds ...

Data & Publications

Characterization of the mesophotic benthic habitat and fish assemblages from ROV dives on Pulley Ridge during 2015 R/V Walton Smith cruise

This cruise was conducted at Pulley Ridge mesophotic reef in the Gulf of Mexico, from August 22 to September 4, 2015, in collaboration with the University of Miami, HBOI-CIOERT, NOAA Fisheries, and the University of North Carolina at Wilmington (UNCW) ...

Characterizing population structure of coral-associated fauna from mesophotic and shallow habitats in the Caribbean

Symbiotic relationships are a common phenomenon among marine invertebrates, forming both obligatory and facultative dependencies with their host. Here, we investigate and compare the population structure of two crustacean species associated with both shallow and mesophotic ecosystems: an obligate symbiont ...

Close encounters with eddies: oceanographic features increase growth of larval reef fishes during their journey to the reef

Like most benthic marine organisms, coral reef fishes produce larvae that traverse open ocean waters before settling and metamorphosing into juveniles. Where larvae are transported and how they survive is a central question in marine and fisheries ecology. While there ...

Community ecology of mesophotic coral reef ecosystems

Given the global degradation of shallow-water coral reef ecosystems resulting from anthropogenic activities, mesophotic coral reef ecosystems (MCEs) are gaining attention because they are generally considered a de facto refuge for shallow-water species. Despite their inferred importance, MCEs remain one ...

Connectivity of Pulley Ridge with remote locations as inferred from satellite-tracked drifter trajectories

Using historical (1994–2017) satellite-tracked surface drifter trajectory data, we conduct a probabilistic Lagrangian circulation study which sheds light on the connectivity of Pulley Ridge with other locations in the Gulf of Mexico and adjacent areas. The analysis reveals that Pulley ...

Cyclonic activity in the eastern Gulf of Mexico: characterization from along-track altimetry and in situ drifter trajectories

The shedding sequence of the Loop Current (LC) inside the Gulf of Mexico (GoM) is strongly influenced by cyclonic frontal eddies around its edge. Along-track altimetry data, analyzed based on a wavelet decomposition to provide estimates of individual cyclones’ diameter, ...

Demographic and reproductive plasticity across depth distribution of a coral reef fish

As humans expand into natural environments, populations of wild organisms may become relegated to marginal habitats at the boundaries of their distributions. In the ocean, mesophotic coral ecosystems (30–150 m) at the depth limit of photosynthetic reefs are hypothesized to act ...

Depth specialization in mesophotic corals (Leptoseris spp.) and associated algal symbionts in Hawaii

Corals at the lower limits of mesophotic habitats are likely to have unique photosynthetic adaptations that allow them to persist and dominate in these extreme low light ecosystems. We examined the host–symbiont relationships from the dominant coral genus Leptoseris in ...

Ecophysiology of mesophotic reef-building corals in Hawai'i is influenced by symbiont-host associations, photoacclimatization, trophic plasticity, and adaptation

Mesophotic reef corals remain largely unexplored in terms of the genetic adaptations and physiological mechanisms to acquire, allocate, and use energy for survival and reproduction. In the Hawaiian Archipelago, the Leptoseris species complex form the most spatially extensive mesophotic coral ...
