          Abstract

          Se realizó un estudio de la dinámica espacial de los crustáceos decápodos asociados a céspedes algales en los municipios de Moñitos, Puerto Escondido y Los Córdobas, Caribe colombiano. Se efectuaron cuatro muestreos trimestrales entre agosto de 2006 y julio de 2007 en cinco puntos de muestreo; dos en Moñitos, dos en Puerto Escondido y uno en Los Córdobas. Para la recolección de los especímenes se delimitó un cuadrante de 625 cm² con cinco repeticiones dispuestas al azar en cada punto de muestreo. Las macroalgas fueron separadas desde su disco de fijación al sustrato y conservadas en bolsas plásticas. Los crustáceos decápodos se conservaron en alcohol al 70%. Se identificó un total de 27 especies de crustáceos decápodos asociadas a los céspedes algales, agrupadas en 13 familias y 19 géneros, registrándose por primera vez Hippolyte pleuracanthus para el Caribe colombiano. Con base en el análisis de clasificación (UPGMA), se determinó que la estructura de las poblaciones de decápodos está relacionada con las características del sustrato rocoso y la composición algal, indicando que las diferencias en las poblaciones son consecuencia de una escala espacial. Los resultados indicaron que de las 27 especies identificadas, Epialtus bituberculatus registró el mayor porcentaje de abundancia (65,7%), seguida de Pachygrapsus transversus (6,2%), Eurypanopeus abbreviatus (3,8%), Acanthonyx petiverii (3,6%), Panopeus sp1. (3,6%) y Panopeus sp2. (3,4%). El resto de las especies aportaron una abundancia ≤2,2%.

          A spatial scale study of decapods crustacean associated with algal assemblages was conducted at Moñitos, Puerto Escondido and Los Córdobas, Colombian Caribbean. During August of 2006 and July of 2007 were realized four samplings in five station; two in Moñitos, two in Puerto Escondido and one in Los Cordobas. A quarter of 625 cm2 was used to collect the species with five repetitions which were chosen at random, in each station. To separate the macroalgae from hold fast, it was used palette knife. The decapods crustaceans were separate in a plastic recipient, and those were preserved in alcohol at 70%, in bottles of plastic which were carefully named. 27 species of decapods associated with algae assemblages were reported, grouped in 13 families and 19 genera. Hippolyte pleuracanthus was registered for first time for the Colombian Caribbean. According to the classification analyses (UPGMA), it was found that the structure of the decapods crustacean were related with characteristic rocky line and algae assemblages, indicating that the differences in the population were consequences of a spatial patterns. The results indicated that of the 27 species identified, Epialtus bituberculatus recorded the highest percentage of abundance (65.7%), followed by Pachygrapsus transversus (6,2%), Eurypanopeus abbreviatus (3,8%), Acanthonyx petiverii, Panopeus sp1. (3,6%) and Panopeus sp2. (3,4%). The rest of the species provided an abundance ≤ 2.2%.
