Coral reefs, kelp forests
and other marine ecosystems may be tougher than we give them credit for, a new
study suggests.
While (1) _______ scientific reports have
documented the ravages of climate change on oceanic life, a survey of the (2)________
who wrote them provides a silver lining: An overwhelming majority noticed
examples of sea life withstanding climate change.
“There are instances where (3)________
ecosystems have shown remarkable resilience after climatic events. You can
think of them as 'bright spots': They demonstrate that there are conditions
under which ecosystems can persist even with major climate (4)__________,” said
Jennifer O'Leary, a marine conservation biologist with California Polytechnic
State University and leader of the study.
The results of the survey were compiled
in a report published in the journal BioScience.
In all, 97 researchers were polled; 80 percent of those who had witnessed
climatic disturbances also reported noting instances of (5)________. A similar
survey that looked at expert-recommended papers on ecosystems found examples of
resilience in 85 percent of them.
In Western Australia,
for instance, a reef lost 90 percent of its live coral after a (6)________ event.
But 12 years later, it had restored itself to 44 percent of its normal size.
Meanwhile, after an El Niño-related current destroyed kelp forests off
California's coast, they were able to bounce back within half a decade.
Identifying examples of resilience and (7)________
the reasons behind it could prove to be a valuable blueprint for conservation
experts, said O'Leary. It could provide them(8) __________ on local conditions
that could bolster ecosystems and guide their strategies to protect them.
