The Caribbean Is Stressed Out

and has no comments yet.
Forty percent of the world’s 2.5 billion people live in coastal cities and towns. A team including Smithsonian marine biologists just released 25 years of data about the health of Caribbean coasts from the Caribbean Coastal Marine Productivity Program (CARICOMP). The study provides new insights into the influence of both local and global stressors in the basin, and some hope that the observed changes can be reversed by local environmental management.

Corals Survived Caribbean Climate Change

and has no comments yet.
Half of all coral species in the Caribbean went extinct between 1 and 2 million years ago, probably due to drastic environmental changes. Which ones survived? Scientists working at the Smithsonian Tropical Research Institute (STRI) think one group of survivors, corals in the genus Orbicella, will continue to adapt to future climate changes because of their high genetic diversity.“Having a lot of genetic variants is like buying a lot of lottery tickets,” said Carlos Prada, lead author of the study and Earl S. Tupper Post-doctoral Fellow at STRI. “We discovered that even small numbers of individuals in three different species of the reef-building coral genus Orbicella have quite a bit of genetic variation, and therefore, are likely to adapt to big changes in their environment.”
