Concentración de clorofila a en colonias de Pocillopora verrucosa (Sderactina) durante un blanqueamiento coralino en el Golfo de California, México (1997)

El Niño-Southern Oscillation 1997-98 significantly elevated sea temperatures in the Gulf of California and caused widespread coral bleaching starting in july 1997. Changes in chlorphyll a concentration by unit of area (cm2) among normal, discolored and totally bleached colonies of the coral Pocillop...
