By David Perlman, San Francisco Chronicle. For GSS Losing Biodiversity chapter 7 and Climate Change chapter 8. Excerpt: Marine biologists at the California Academy of Sciences have joined a new international effort to rescue endangered coral reefs from the consequences of widespread human destruction and a warming climate. Teams of research divers from the academy will set off this summer on expeditions to the Caribbean and Mexico, where they will seed two of the region’s major reefs with millions of coral larvae born from the organisms’ sperm and egg cells. ...corals are actually colonies of tiny animals that build their limestone homes from the sea, and derive their colors from the algae that live inside them. Their lives are increasingly threatened by global plagues like expanding human development, ocean pollution, and the twin signals of global climate change: rising temperatures and increasing ocean acidification. ...The expedition is scheduled for August because the corals spawn only about once a year, releasing their sex cells into the water by the millions, Shepherd explained. The event, he said, occurs only in August at night and only within a few days after a full moon....  http://www.sfgate.com/bayarea/article/In-vitro-fertilization-may-save-coral-reefs-8326086.php
