Some Corals are Said to be Adapting to Climate Change

Effects of global warming have started to show as different species are likely to become extinct in the coming years. Corals for example, have an important role to play to keep ecological balance. In recent months, reports came out that the increased temperature of earth is causing death of global coral family. However, new study has shown that the some coral species have started to adapt with the changing climate condition.

The latest research was conducted in national marine parks of Kenya as WCS Senior Conservation Zoologist Tim McClanahan, carried out the research. In order to find out the effects of climate changes on corals, he looked at similar events from the past and found that the number of pale and bleached coral colonies declined from 73 to 27 percent, and 96 to 60 percent in the two parks with different background temperatures.

If you didn’t know, bleaching takes place when corals releases algae that serve as energy resources for corals in hostile environment. In last year, events of bleaching have gone up as the ocean water have become surprisingly warm. Talking about the research McClanahan said, “This was a rare chance to study bleaching responses during two separate times with very similar conditions. Adaptation is evident for some of the more important reef building corals but, sadly, many species are not adapting, so this is a good news-bad news story.”

“Evidence for adaptation in the past is not evidence for adaptation in the future. Nevertheless, I suspect this adaptation to hot water started before my 1998 work and could have begun during the 1983 and 1988 El Ninos, when coral bleaching was first observed in the region.”

“Despite the many caveats and interpretation of these results, this study provides one of the first response-rate estimates for many common corals at the population level. It therefore provides a basis for future studies and improving model predictions and the types of evaluations needed to address the future health of coral reefs.”
