[font size=4]Western Australian reefs faring better than eastern counterparts[/font]

[font size=3]Corals on Australia’s Great Barrier Reef have fallen on hard times recently. But on the opposite side of the continent, their West Coast brethren have been living the good life for at least a century, a new study finds.
Global warming may be helping these creatures out — at least for now. “To date, it is the changes in temperature that are having the dominant impact on coral growth,” says Timothy Cooper, a marine biologist at the Australian Institute of Marine Science in Crawley.
To compare how reefs in different places have been doing, Cooper and colleagues collected samples of Porites coral at six spots off Australia in the southeastern Indian Ocean. Porites build skeletons with layers that, like tree rings, can be used to measure growth from year to year.
None of creatures had slowed their growth in the last 110 years, Cooper’s team reports in the Feb. 3 Science. Those at the southernmost sites have even been building reefs faster as surface waters there have warmed markedly.
