Reef boom beats doom
Marine scientists say they are astonished at the spectacular
recovery of certain coral reefs in Australia's Great Barrier Reef
Marine Park from a devastating coral bleaching event in 2006.
That year high sea temperatures caused massive and severe
coral bleaching in the Keppel Islands, in the southern part of
the GBR. The damaged reefs were quickly smothered by a
single species of seaweed — an event that can spell the total
loss of the corals. However, a lucky combination of rare
circumstances meant the reefs were able to achieve a
spectacular recovery, with abundant corals re-established in a single year,
says Dr Guillermo Diaz-Pulido,
from the ARC Centre of Excellence for Coral Reef Studies (CoECRS) and the
Centre for Marine Studies at The University of Queensland. Dr Diaz-Pulido
explains that the rapid recovery is due to an exceptional combination of
previously-underestimated ecological mechanisms.
