Can biological invasions save Caribbean coral reefs?

Abstract

It is widely accepted that coral reefs are in decline globally, due to climate change as well as more direct human impacts such as poor water quality and overharvesting. Biological invasions are also seen as a major threat; however, they may not all be negative. An invasion of Red Sea rabbitfishes is disrupting Mediterranean ecosystems by removing macro-algae - meanwhile, in contrast, the Caribbean is suffering from excess macro-algal growth.
