Effects of Climate and Seawater Temperature Variation on Coral Bleaching and Mortality
Coral bleaching due to thermal and environmental stress threatens coral reefs and possibly people who rely on their resources. Here we explore patterns of coral bleaching and mortality in East Africa in 1998 and 2005 in a region where the equatorial current and the island effect of Madagascar interact to create different thermal and physicochemical environments. A variety of temperature statist...
متن کاملGrowth, differentiation and death of Vibrio shiloi in coral tissue as a function of seawater temperature
The coral pathogen Vibrio shiloi was present during the summer in the tissues of all of its host corals, Oculina patagonica , which were bleached. During the winter, when seawater temperatures dropped below 20°C, V. shiloi could not be detected in either healthy or bleached corals, even when the corals were placed in aquaria and the temperature was slowly increased to 28°C. Using specific anti-...
متن کاملStorm-mediated coral colonization by an excavating Caribbean sponge
The broken, dead stands of the Caribbean elkhorn coral Acropora palmata, which suffered massive mortalities from disease and bleaching during the early 1980s, are now widely covered by Cliona tenuis, an encrusting and excavating brown sponge (Hadromerida, Clionaidae). This sponge displaces live coral tissue by undermining the polypal skeletal support. On the windward fringing reef of Islas del ...
متن کاملWarm-water coral reefs and climate change.
Coral reefs are highly dynamic ecosystems that are regularly exposed to natural perturbations. Human activities have increased the range, intensity, and frequency of disturbance to reefs. Threats such as overfishing and pollution are being compounded by climate change, notably warming and ocean acidification. Elevated temperatures are driving increasingly frequent bleaching events that can lead...
متن کاملIncreased seawater temperature increases the abundance and alters the structure of natural Vibrio populations associated with the coral Pocillopora damicornis
Rising seawater temperature associated with global climate change is a significant threat to coral health and is linked to increasing coral disease and pathogen-related bleaching events. We performed heat stress experiments with the coral Pocillopora damicornis, where temperature was increased to 31°C, consistent with the 2-3°C predicted increase in summer sea surface maxima. 16S rRNA amplicon ...
