Hi all,
Tehre was some spawn of Acropora cervicornis during last weekend in Puerto 
Rico. Last saturday, August 16 one colony spawned between 9:20-9:40pm. Two 
other colonies spawned last sunday, August 17 at the same hour. Also, two 
branches from the colony that spawned on saturday (these branches did not 
spawned on saturday) spawned on sunday too. A different colony released only 
a couple of bundles and another only released one bundle. All these colonies 
were at 1m depth in San Cristóbal reef in La Parguera reef platform.
