Variación espacio-temporal de grupos morfo-funcionales de macroalgas en pastos marinos al norte de Ciego de Ávila, Cuba.

Abstract

Se determinó la variación espacio-temporal de la biomasa de los grupos morfo-funcionales de macroalgas y su relación con las variables ambientales: temperatura, salinidad, oxígeno disuelto y precipitaciones en dos localidades (laguna y playa) de pastizales al Norte de Ciego de Ávila desde marzo de 2010 a febrero de 2011. Las colectas se realizaron utilizando marco cuadrado de 25 cm de lado y se tomaron 15 unidades de muestreo en cada sitio. Se determinaron cinco grupos morfo-funcionales: foliosas y globosas, coriáceas, filamentosas, corticadas y calcáreas articuladas, presentando variaciones espacio-temporales los dos últimos. La laguna tuvo menor diversidad algal (13 géneros) y mayor biomasa total determinado por el aporte de las calcáreas articuladas, mientras que la playa fue más diversa (26 géneros) y menos productiva. Los picos máximos se presentaron en verano debido al enriquecimiento producto del arrastre por las lluvias y los mínimos enprimavera. Las variaciones espaciales pudieron estar dadas por las diferencias del régimen hidrodinámico, los nutrientes y el sustrato. La variación temporal de la biomasa de las corticadas y filamentosas mostró correlación con valores elevados de salinidad y oxígeno disuelto y las calcáreas articuladas y coriáceas lo fueron para valores elevados de temperatura y precipitaciones.
