Coastal ecosystems, such as coral reefs, are particularly vulnerable to mercury contamination due to direct contact with terrestrial sources. Here, we evaluated, for the first time, the concentration of mercury in coral reefs in the Southwestern Atlantic using the amphi-atlantic scleractinian coral Montastraea cavernosa.

Broadcast spawning by corals is a tightly synchronized process characterized by co-ordinated gamete release within 30–60 min time windows once per year. In shallow water corals, annual water temperature cycles set the month, lunar periodicity the day, and sunset time the hour of spawning.

AbstractWhile physiological responses to low‐light environments have been studied among corals on mesophotic coral ecosystems worldwide (MCEs; 30–150 m), the mechanisms behind acclimatization and adaptation to depth are not well understood for most coral species.

Successful management of spatially isolated coral reefs is contingent on an understanding of ecological connections across populations. To investigate genetic connectivity of the depth-generalist coral species Montastraea cavernosa, populations from both shallow (15–30 m) and mesophotic coral ecosystems (30–70 m) in the Gulf of Mexico (GOM) were ...

Recent advances in morphometrics and genetics have led to the discovery of numerous cryptic species in coral reef ecosystems. A prime example is the Montastraea annularis scleractinian coral species complex, in which morphological, genetic, and reproductive data concur on species boundaries, allowing evaluation of long-term patterns of speciation and ...

To investigate sex-related differences in the skeleton of the reef-building coral Montastraea cavernosa, a gonochoric broadcaster species with an annual cycle of gametogenesis, we collected six colonies during the reproductive season. Sex was determined by histological techniques and sclerochronological characteristics of digital X-ray images.

It is critical to determine the methods by which coral colonies regenerate tissue lost to physical injury as they provide the physical structure of coral reef systems. To explore regeneration, circular lesions (12 mm diameter × 3 mm depth) were created in the fall of 2014 on 124 Montastraea cavernosa colonies located in the coastal waters of Grenada ...

Severe coral mortality after bleaching is well documented in the Indo-Pacific and Caribbean, but in the marginal Southwestern Atlantic, corals often exhibit lower post-bleaching mortality and high recovery following temperature anomalies. Understanding how these corals respond to environmental fluctuations can provide insights into their resilience ...

Climate change and other types of environmental stress are known to increase corals’ vulnerability to bleaching, a process whereby colonies lose their colour either due to the loss of photosynthetic symbionts or their pigments. Although bleaching leaves the coral skeleton visible under its transparent tissue, not all white coral colonies display this ...
