Corals Much Older Than Previously Thought, Study Finds
Coral genotypes can survive for thousands of years, possibly making them the longest-lived animals in the world, according to researchers at Penn State, the National Marine Fisheries Service and Dial Cordy & Associates. The team recently determined the ages of elkhorn corals—Acropora palmata—in Florida and the Caribbean and estimated the oldest genotypes to be over 5,000 years old. The results are useful for understanding how corals will respond to current and future environmental change.
Study Offers Coastal Communities Better Way To Prepare For Devastating Storms
Coastal storms can cause surges, sea-level rise, and cyclone winds that devastate communities. But emergency management experts in a new study detail a method for involving local stakeholders in planning for such extreme events and thereby helping such vulnerable areas in becoming more resilient. Coastal communities’ ability to plan for, absorb, recover and adapt from destructive hurricanes is becoming more urgent. As of 2010, approximately 52 percent of the United States’ population lived in vulnerable coastal watershed counties, and that number is expected to grow. Globally, almost half of the world’s population lives along or near coastal areas.
