Influence of the density of Caulerpa prolifera (Chlorophyta) on the composition of the macrofauna in a meadow in Algeciras Bay (Southern Spain)

The coverage and biomass fluctuations of Caulerpa prolifera (Chlorophyta) were used to assess the influence of the alga on the composition of its associated animal community, on a small spatial scale. Bymeans of ordination analysis, based on species abundance, a series of groups, related to the diff...

Bymeans of ordination analysis, based on species abundance, a series of groups, related to the different algal density recorded, were obtained: those stations with highest algal biomass (stations 1, 2 and 8) and the remaining stations (medium and low biomass). According to a canonical correspondence analysis, total algal biomass, coverage and percentage of organic matter explained the differences in the composition of the macrobenthic communities. The response of some species to the spatial distribution of the alga are also discussed. In conclusion, the patchiness of Caulerpa beds cause a high degree of heterogeneity in a spatially reduced system, suggesting the importance of these sites for the biodiversity in coastal ecosystems. Las fluctuaciones de biomasa y cobertura de Caulerpa prolifera (Chlorophyta) se utilizaron para estimar la influencia de la presencia del alga sobre la composición de la comunidad animal asociada, en una pequeña escala espacial. Por medio de análisis de ordenación, basados en la abundancia de las distintas especies, se han obtenido agrupaciones de estaciones relacionadas con la diferente densidad de alga. Fundamentalmente, se han diferenciado aquellos puntos con mayor biomasa algal (estaciones 1, 2 y 8) y el resto de las estaciones de muestreo (biomasa media o baja). De acuerdo con los resultados del análisis de correspondencias canónicas, la biomasa total de alga, la cobertura y el porcentaje de materia orgánica del sedimento son los factores que explican las diferencias en la composición de las comunidades de macrobentos. Se discuten las respuestas de diversas especies a la distribución espacial del alga. En definitiva, las discontinuidades de Caulerpa propician un alto grado de heterogeneidad en un sistema tan reducido espacialmente como éste, lo que pone de manifiesto la importancia de estos enclaves para el mantenimiento de la biodiversidad en el sistema litoral.
