Diazotrophic diversity in the Caribbean coral, Montastraea cavernosa

Archives of Microbiology, 2013
Previous research on the Caribbean coral Montastraea cavernosa reported the presence of cyanobacterial endosymbionts and nitrogen fixation in orange, but not brown, colonies. We compared the diversity of nifH gene sequences between these two color morphs at three locations in the Caribbean and found that the nifH sequences recovered from M.

Cellular reactions to sedimentation and temperature stress in the Caribbean coral Montastraea cavernosa

Journal of Invertebrate Pathology, 2007
We present evidence of cellular responses to increased sedimentation and temperature in Montastraea cavernosa collected off Broward County, Florida. We sampled corals from six different sites approximately, 500-1000 m off shore, 10-15m depth. Six samples were collected from four sites adjacent to areas of underwater marine dredging (project sites ...

Differential protein abundance associated with delayed regeneration of the scleractinian coral Montastraea cavernosa

Coral Reefs, 2020
Scleractinian corals provide the three-dimensional structure and function of coral reefs around the globe. These sessile animals are subject to physical injuries from a variety of sources and can completely regenerate damaged tissue as a survival mechanism; however, tissue regeneration rates vary widely within and across taxa.

Aposematic coloration does not deter corallivory by fish on the coral Montastraea cavernosa

Coral Reefs, 2016
Predation on corals by visual predators is a significant source of partial or total mortality on coral reefs, and corals have evolved strategies, including chemical defenses, to deter predation. One mechanism that organisms use to communicate the presence of chemical defenses is aposematic coloration, or the display of bright coloration as a warning to

Mercury in the Southwestern Atlantic reef-building coral Montastraea cavernosa (Cnidaria, Scleractinia)

Chemosphere
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.

Conserved Pigment Profiles in Phylogenetically Diverse Symbiotic Bacteria Associated with the Corals Montastraea cavernosa and Mussismilia braziliensis

Microbial Ecology, 2020
Pigmented bacterial symbionts play major roles in the health of coral holobionts. However, there is scarce knowledge on the diversity of these microbes for several coral species. To gain further insights into holobiont health, pigmented bacterial isolates of Fabibacter pacificus (Bacteroidetes; n = 4), Paracoccus marcusii (Alphaproteobacteria; n = 1 ...

Population structure and connectivity in the Atlantic scleractinian coral Montastraea cavernosa (Linnaeus, 1767)

Marine Ecology, 2011
AbstractCoral reefs are increasingly threatened worldwide by a variety of biological and physical factors, including disease, bleaching and ocean acidification. Understanding levels of connectivity among widespread populations can assist in conservation efforts and the design of marine protected areas, as larval dispersal scales affect population ...

Polymorphism in a common Atlantic reef coral (Montastraea cavernosa) and its long-term evolutionary implications

Evolutionary Ecology, 2011
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 ...

Deepwater broadcast spawning by Montastraea cavernosa, Montastraea franksi, and Diploria strigosa at the Flower Garden Banks, Gulf of Mexico

Coral Reefs, 2006
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.

White but not bleached: photophysiological evidence from white Montastraea cavernosa reveals potential overestimation of coral bleaching

Marine Biology, 2015
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 ...
