Fine‐grained sediment production by endolithic sponges on Caribbean coral reefs

Limnology and Oceanography, Volume 69, Issue 9, Page 2015-2028, September 2024.
Abstract Endolithic sponges are key players in carbonate cycling on coral reef systems. While their bioerosion of reef framework is relatively well studied, their role in biogenic sediment generation is poorly understood. In this study, the sedimentary attributes and production rates of eight Caribbean endolithic sponge species were characterized.

Three-dimensional molecular cartography of the Caribbean reef-building coral Orbicella faveolata [PDF]

, 2021
All organisms host a diversity of associated viruses, bacteria, and protists, collectively defined as the holobiont. While scientific advancements have enhanced the understanding of the functional roles played by various components of the holobiont, there is a growing need to integrate multiple types of molecular data into spatially and temporally ...

Changes in the Number of Symbionts and Symbiodinium Cell Pigmentation Modulate Differentially Coral Light Absorption and Photosynthetic Performance

Frontiers in Marine Science, 2017
In order to understand the contribution of pigmented coral tissues to the extraordinary optical properties of the coral-symbiont-skeleton unit, we analyzed the associations between structural and optical traits for four coral species, which broadly ...

South Atlantic Multi‐Site Calibration of Coral Oxygen Isotope Paleothermometer

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 8, August 2024.
Abstract Coral‐based stable oxygen isotopes (δ18O) have been used as a proxy for sea surface temperature (SST) since the 1970s, and δ18O–SST calibration studies have been fundamental to assure robust and faithful SST reconstructions. Paleoclimatic studies based on corals from the tropical western South Atlantic (TWSA) are scarce, and the available ...

Differential susceptibility of reef-building corals to deoxygenation reveals remarkable hypoxia tolerance

Scientific Reports, 2021
Ocean deoxygenation threatens the persistence of coastal ecosystems worldwide. Despite an increasing awareness that coastal deoxygenation impacts tropical habitats, there remains a paucity of empirical data on the effects of oxygen limitation on reef ...

Triggers, cascades, and endpoints: connecting the dots of coral bleaching mechanisms

Biological Reviews, Volume 99, Issue 3, Page 715-752, June 2024.
ABSTRACT The intracellular coral–dinoflagellate symbiosis is the engine that underpins the success of coral reefs, one of the most diverse ecosystems on the planet. However, the breakdown of the symbiosis and the loss of the microalgal symbiont (i.e.

The impact of stony coral tissue loss disease and amoxicillin treatments on coral gametogenesis

Frontiers in Marine Science
The unprecedented mortality of stony corals on Florida’s Coral Reef from stony coral tissue loss disease (SCTLD) was mitigated on some priority sites and corals through the use of a topical amoxicillin paste to halt disease lesion progression.

20th Century Warming in the Western Florida Keys Was Dominated by Increasing Winter Temperatures

Paleoceanography and Paleoclimatology, Volume 39, Issue 2, February 2024.
Abstract Long‐lived Atlantic coral species like Orbicella faveolata are important archives of oceanographic change in shallow, marine environments like the Florida Keys. Not only can coral‐based records extend for multiple centuries beyond the limits of the instrumental record, but they can also provide a more accurate representation of in situ ...

Reef‐wide and long‐term skeletal growth records of the mountainous star coral (Orbicella faveolata) from Belize barrier and atoll reefs (Central America)

Journal of Quaternary Science, Volume 39, Issue 1, Page 145-162, January 2024.
Abstract Coral reefs are vulnerable marine ecosystems and reef‐building corals are especially sensitive to the impacts of environmental change. Skeletal growth records of corals (Scleractinia) can be used as archives of ecological and climatological change.

Southeast Florida Large Coral Assessment 2015 [PDF]

, 2015
The 2013 nearshore mapping project conducted by Walker and Klug expanded the previous knowledge on the amount, location, and species type of ecologically important large (\u3e2 m) coral colonies in southeast Florida.
