Ficoflora de los arrecifes coralinos del archipiélago Sabana-Camagüey, Cuba

Abstract

Para obtener una primera aproximación al conocimiento de las comunidades de macroalgas de los arrecifes de coral del archipiélago Sabana–Camagüey, se realizaron muestreos en 10 perfiles a lo largo del gradiente de profundidad, ubicados en los arrecifes de borde de plataforma de los cayos Sabinal, Guajaba, Confites, Coco, Paredón del Medio, Oeste de cayo Guillermo, Caimán Grande, Francés, Fragoso y Esquivel. En cada perfil se tomaron muestras de algas en cuatro estaciones situadas en la zona trasera del arrecife a 1 m de profundidad, y en el arrecife frontal a 5, 10 y 20 m de profundidad. Estas fueron tomadas con un colector hidroneumático circular de 0.07 m2 de área. Se encontraron 130 especies de algas. La mayor riqueza de especies se presentó en las estaciones de 5 m de profundidad del arrecife frontal. El predominio de las especies en la zona trasera y 20 m de profundidad del arrecife frontal fue heterogéneo, mientras que en 5 m de profundidad predominó la especie Cladophora catenata, y en 10 m Cladophora catenata y Microdictyon marinum. Las especies de mayor frecuencia de aparición en las cuatro profundidades fueron: Cladophora catenata, Anadyomene stellata, Microdictyon marinum, Halimeda tuna y Valonia ventricosa. La biomasa total varió con las localidades y la profundidad, pero fue mayor a los 5 m del arrecife frontal. Los altos valores de biomasa en toda la zona arrecifal parecen estar ocasionados por los altos niveles de nutrientes en el agua y la escasez de herbívoros.

With the purpose of obtaining a first approximation to the knowledge of coral reef macroalgae communities in Sabana-Camagüey Archipelago, 10 profiles along the depth gradients, located on the shelf border reefs were sampled in the keys Sabinal, Guajaba, Confites, Coco, Paredón del Medio, West of Guillermo, Gran Caimán, Francés, Fragoso and Esquivel. In each profile, algae samples were taken at four stations located in the rear zone at 1 m deep, and in the fore reef at 5, 10 and 20 m deep. A circular hydro-pneumatic collector with a 0.07 m2 area was used. A total of 130 algae species were found. The highest species richness was observed at 5 m deep on the fore reef. The predominant species in the rear zone and at 20 m deep on the fore reef varied among profiles; at 5 m depth the dominant species was Cladophora catenata, while at 10 m were Cladophora catenata and Microdictyon marinum. The most frequently occurring species in the four depths were: Cladophora catenata, Anadyomene stellata, Microdictyon marinum, Halimeda tuna and Valonia ventricosa. Total biomass varied with locations and depths, but was higher at 5 m deep on the fore reef. High biomass values in the whole reef zone seem to be caused by high levels of nutrients and herbivore scarcity.
