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

open access: yesFrontiers 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 ...

Increased Algal Symbiont Density Reduces Host Immunity in a Threatened Caribbean Coral Species, Orbicella faveolata

open access: yesFrontiers in Ecology and Evolution, 2020
Scleractinian corals are the principal builders of coral reefs. These megadiverse ecosystems are declining due to coral mortality from a variety of stressors, including disease.

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

open access: yesLimnology 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.

South Atlantic Multi‐Site Calibration of Coral Oxygen Isotope Paleothermometer

open access: yesGeochemistry, 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 ...

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

open access: yesFrontiers 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.

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

open access: yesBiological 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.

Source location and food availability determine the growth response of Orbicella faveolata to climate change stressors [PDF]

open access: yesRegional Studies in Marine Science, 2017
Abstract The local environment shapes coral physiology through acclimatization and also selects for genotypes best suited to a particular site. Both acclimatization and selection likely affect the response of corals to future climate change. The local environment is therefore an important factor to consider for restoration ecology.

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

open access: yesPaleoceanography 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 ...

Southeast Florida Large Coral Assessment 2015 [PDF]

open access: yes, 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.

Assessing Long-Term Coral Coverage at East and West Flower Garden Banks [PDF]

open access: yes, 2021
Coral reefs provide critical habitat for diverse benthic communities; however, more than 10% of existing reefs have been lost as a result of natural and anthropogenic stressors.
