Coral recruits in the Jardines de la Reina National ParkAbstract
El reclutamiento de corales es un proceso ecológico clave para el mantenimiento y recuperación de poblaciones naturales en los arrecifes coralinos. Para determinar el número de reclutas de corales, en el Parque Nacional Jardines de la Reina, se utilizó un marco de 0.25 m x 0.25 m, el cual fue colocado cada 2 m, en transectos de 10 m de largo, hasta completar 50 cuadrados en cada sitio de estudio. Se estudiaron 12 sitios en crestas de arrecifes y 24 en escarpes pocos profundos. En las crestas de arrecifes, los sitios se distribuyeron en tres zonas de reserva y en los escarpes, en cinco zonas de reserva. En las crestas la densidad promedio de reclutas no manifestó di- ferencias significativas para las zonas de la reserva (p<0.292). Se identificaron seis especies, predominando Porites astreoides en la zona de la Reserva Oeste (4.8 colonias/m2) y Agaricia spp. en la Reserva Extremo Oeste (3.8 colonias/m2). En los escarpes se apreciaron diferencias significativas, principalmente, entre la zona de Reserva Extremo Este y la Reserva Extremo Oeste (p<0.009). Se identificaron 19 especies, predominando Agaricia spp. (13.1 colonias/m2) y Siderastrea siderea (14.1 colonias/m2) en la zona de la Reserva Oeste. La mayor densidad de reclutas de corales se concen- tra hacia el Oeste, siendo el hábitat de los escarpes pocos profundos donde prevalecieron las mayores densidades.Coral recruitment is a key ecological process for the maintenance and recovery of natural populations in coral reefs. To determine the number of coral recruits, in the Jardines de la Reina National Park, a frame (0.25 m x 0.25 m) was used. The frame was placed every 2 m, in 10 m long transects, until 50 squares were completed in each study site. A total of 12 sites on reef crests and 24 sites on slopes were studied. On the reef crests, the sites were distributed among three reserve zones and on the slopes, the sites were distributed among five reserve zones. On the crests, the average density of recruits did not show significant differences for the ar- eas of the reserve (p<0.292). Six species were identified, predominantly Porites astreoides at the Reserva Oeste zone (4.8 colonies/m2) and Agaricia spp. in the Reserva Extremo Oeste (3.8 colonies/m2). On the slopes, significant differences were observed, mainly, between the Reserva Extremo Este and the Reserva Extremo Oeste (p<0.009). Nineteen species were identified, predominantly Agaricia spp. (13.1 colonies/m2) and Siderastrea siderea (14.1 colonies/m2) in the Reserva Oeste. The highest density of coral recruits is found towards the West of the park, and in particular, it was on slopes where the highest densities prevailed.
