Impact of a coral disease outbreak on coral communities in St. Lucia: What and how much has been lost?
Among-colony size variation in disease incidence and tissue mortality indicates that small coral colonies are more likely to escape infections than large colonies, but once infection occurs, small colonies will experience faster colony mortality.
Algal contact as a trigger for coral disease
It is shown that physical contact with the macroalga Halimeda opuntia can trigger a virulent disease known as white plague type II that has caused widespread mortality in most Caribbean coral species and that reduction of macroalgal abundance could help control coral epizootics.
Coral mortality and interaction with algae in relation to sedimentation
It is concluded that sedimentation may lead to reef degradation by causing coral mortality through sediment smothering and burial, and then by suppressing the regrowth of surviving adult colonies through increased competition with algae.
Benthic community changes associated with intertidal oyster cultivation
Small, but significant, changes were detected in the macrofaunal community sampled beneath oyster trestles compared with that found in adjacent uncultivated areas, associated with an increase in organic and silt composition and a reduction in the depth of the oxygenated layer of the sediment beneath the trestle.
In Situ Oxygen Dynamics in Coral-Algal Interactions
The results showed that hypoxia was not a consistent feature in the microenvironment of the coral-algal interface under in situ conditions, andhypoxia alone is unlikely to be the cause of coral mortality.
Porites and the Phoenix effect: unprecedented recovery after a mass coral bleaching event at Rangiroa Atoll, French Polynesia
Rapid post-bleaching recovery is unprecedented in massive Porites and resulted from remarkable self-regeneration termed the ‘Phoenix effect’, whereby remnant cryptic patches of tissue that survived the 1997/1998 ENSO event regenerated and rapidly overgrew adjacent dead skeleton.
Differential competitive abilities between Caribbean coral species and a brown alga: a year of experiments and a long-term perspective
It is suggested that a species-by-species approach is needed to understand the factors influencing transitions from coral to algal dominance on Caribbean reefs, and competition with algae could play a significant role in structuring coral communities by reducing the abundance of poor competitive species.
