Popis:	Growth rates (skeletal linear extension) of columnar and lobate morphotypes of the reef-building coral Montastrea annularis were compared within and among seven fringing reefs along a previously described eutrophication gradient on the west coast of Barbados using X-ray radiography. Both morphotypes of M. annularis exhibit similar patterns of increasing average growth rates with improving environmental conditions. However, the average growth rates of the columnar morphotype are statistically higher (P Index master chronologies computed for a columnar morphotype of M. annularis indicate a general pattern of decreasing growth rates within the past 30 yr at each of the seven fringing reefs. It is postulated that this general pattern of decreasing growth rates may be directly related to the deterioration of water quality along the west coast of the island.
