Quantitative tracking of the cellular and skeletal response of the Caribbean coral Orbicella annularis to gradients in marine sewage pollution
Orbicella annularis is an abundant framework-building Scleractinian coral that serves as an ecological cornerstone throughout the Caribbean Sea. The O. annularis holobiont (all interacting biotic and abiotic components making up the coral) is negatively impacted by increased exposure to …

Carbon cycling in the Caribbean reef-building coral Orbicella: quantitative evidence for enzymatic control of skeletal density banding and coral-endosymbiont physiological plasticity during seasonal environmental change
Although modern Metazoan corals construct Earth’s wave-resistant coral reefs, serve as a cornerstone of marine ecology, and may help mitigate the accumulation of greenhouse gases by building a skeleton (composed of a calcium carbonate mineral called aragonite) that functions as a carbon sink, the …

Tropical stony corals host diverse microbial nitrogen dynamics
… sampled at multiple sites (Porites porites and Orbicella faveolata) showed similar trends among replicates and within genera (Porites). We also examine the impact of light and dark treatments on coral-associated nitrogen cycling. We hypothesized that dark conditions would stimulate anoxia via …

Effects of Temperature stress on coral fluorescence and reflectance
… species of coral: Acropora cervicornis, Orbicella annularis, and Porites furcata. All species exhibited signs of stress and bleaching after the experiment, based on their chlorophyll fluorescence and reflectance responses. Upon exposure to water temperatures raised incrementally from 31C …
