| Abstract |
Coral reefs provide ecosystem services to humans, essential to protection through different conservation strategies. However, planning and implementing marine conservation management actions must be based on the best available science. Information gaps have resulted in limited knowledge of conservation priorities and a weak conflict resolution and decision-making capacity. The San Felipe Keys National Park (SFKNP), located in the southwestern region of Cuba, is an understudied area with 40 km long forereefs, providing services mainly associated with fisheries (lobster and finfish). This work analyzed the hermatypic coral assemblage structure and condition within the SFKNP and the influence of geographic and environmental factors in its variation. Using stereo videos, we assessed nine coral reef sites between 2013 and 2015, generating 597 transects, in which 10341 colonies, 46 species, and 17 functional entities were found. The dominant species (Siderastrea siderea, Porites astreoides, Agaricia agaricites, and Orbicella faveolata) are mainly massive species with higher depth range, and that visibility in the bottom and habitat heterogeneity explained 57% of coral assemblages’ variation. Besides, the percentage of living coral cover (10%–15%), the prevalence of small-sized colonies (22 cm average), and the high incidence of recent mortality (2%–8% of colonies) indicate the presence of environmental stressors in the SFKNP, such as water turbidity, generated by the natural runoff from the Gulf of Batabanó. These results highlight the importance of enhancing the awareness of the competent authorities and promoting integrated management of the entire western region of the Gulf of Batabanó. |
