New research on coral reefs led by the University of Southampton suggests that existing biodiversity will be essential for the successful adaptation of ecosystems to climate change. About 25% of all marine biodiversity depends on coral reefs, the three-dimensional calcareous framework laid down by the coral animals together with their algal symbionts. Climate change, in particular increasing seawater temperatures, threatens to disrupt the functionality of this productive association with potentially devastating knock-on effects to ecosystem…
