Knowledge of how... click to read more
The silent battle of young corals against ocean acidification
Coral reefs are ecosystems of extraordinary diversity. Considered "the rainforests of the sea", they contain ~35% of described marine species despite only occupying 0.2% of the world's ocean. Although they are extremely important habitat providers and form large living structures (some reefs can be seen... click to read more
