Focussing on four key locations in the Pacific and Caribbean, and using data from sites that have been surveyed for at least a decade, the research team identified small pockets of life where the coral appeared to be either escaping, resisting or rebounding from changes to their environment.

Publishing their findings today in the Journal of Applied Ecology, the team hope these new findings will encourage further study into why these small communities of corals are surviving while so many more are not, and inspire efforts to identify similar "oases" in other ecosystems.
