From Biology News Net:
In a study that marks progress in understanding the basis of coral reef recovery, researchers have revealed the critical importance of a rare batfish, Platax pinnatus, in promoting the return to health of a disturbed coral reef overgrown with algae.
The findings bring to light a previously unrecognized role for the batfish species, which had not been considered a significant player in reef recovery after overfishing.
In doing so, the study provides insight into the poorly understood—and potentially complex—forces that influence the state of coral reefs under ecological stress.
The work appears in the December 19th issue of the journal Current Biology, published by Cell Press, and is reported by David Bellwood, Terry Hughes, and Andrew Hoey of the Australian Research Council Centre of Excellence for Coral Reef Studies at James Cook University.
