Corals show remarkable loyalty to their home

Washington, June 27 (ANI): A recent study by Australian biologist Jim Underwood has found that despite the fact that corals cast their eggs and sperm haphazardly into the oceans, certain species of coral show remarkable loyalty to their home range.

Underwood sampled DNA from coral reefs in the Indiana Ocean and found that individual corals located in the same group of reefs are more closely related than previously thought.

These results suggest that since most recruitment of these Indian Ocean coral populations comes from other locally sourced coral, one cannot depend on genetic material from distant populations of corals to replenish or restore degraded local populations.

Scientists suggest that in these regions, marine reserves that maintain high local genetic diversity should be favoured. (ANI)

Global sunscreen might cool Earth, but it won't save corals

Washington, June 17 (ANI): A new study has determined that though an artificially 'geoengineered' global sunscreen would lower the planet's temperature by a few degrees, it won't stop the acidification of the world oceans that threatens coral reefs and other marine life.The culprit is atmospheric carbon dioxide (CO2), which even in a cooler globe will continue to be absorbed by seawater, creating acidic conditions."There would be a slight reduction in this problem, because land plants would be expected to.....
