Loss of picky-eating fish threatens coral reef food webs

Coral reefs all over the world, already threatened by rising temperatures brought about by climate change, also face serious challenges from the possibility of fish species extinctions. According to a paper out today in the Proceedings of the National Academy of Sciences, the networks of predator fish and their prey found on coral reefs all over the world are remarkably similar, and those predator fish are pickier eaters than previously thought. These delicate ecosystems become even more vulnerable when these specialized hunters go extinct.
