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.
