| Coral reef condition north of the Havanan provinces (NW Cuba), an area with variable influence from human settlements and runoff, was assessed using the AGRRA methodology’s benthic biological indicators: live coral cover, coral density, maximum colony diameter, old and recent coral mortality, coral recruitment, Diadema antillarum density, and macroalgae cover. Coral communities at 11 reef crest and 22 forereef sites were sampled during 2004. The Shannon heterogenety and Pielou evenness indices were calculated. A total of 33 species of coral, larger than 10 cm in maximum diameter, were identified. The biological indicators analyzed showed significant differences among sites, which suggest a marked heterogeneity in environmental conditions along the study... |
