dc.description The current work analyzes the composition and structure of macroinfaunal communities associated with soft bottoms and their relationship to different environmental variables on the south side of Taganga Bay, Colombian Caribbean during the dry season. Three sites were established through the Taganga south coast parallel to the shoreline in an isobath of 5-15 meters in depth and distance between stations of approximately 1 km. Five samples were collected during December 2008, March and June 2009 using a plastic hand corer with a coverage area of 0,01m² x 10 cm, giving a sampling area of 0,04 m². The variables evaluated were temperature, salinity, transparency, nitrites, total suspended solids (TSS) and their organic fraction, percentage of organic matter, calcium carbonate, sandy index and grain size. A total of 2957 organisms were identified in 93 families spread over the  macrofauna densities ranging between 118 and 638 organisms / 0.04 m2 and belonging to nine biological groups represented by annelids, arthropods, chordates, echinoderms, molluscs, nemerteans, platyhelminths and sipunculids. Biomass values reached 3.751g. The similarity analysis ANOSIM identified no differences in composition and structure of the macrobenthic community temporarily or geographically, indicating the presence of a single continuous community en-US
dc.description Este trabajo analiza la composicion y la estructura de la comunidad de macroinfauna de fondos blandos y su relacion con diferentes variables ambientales en el costado sur de la Bahia de Taganga, Caribe Colombiano durante la epoca seca. Se establecieron tres localidades en una isobata de 5 a 15 metros de profundidad y a una distancia entre estaciones de 1km. Se recolectaron cinco muestras por estacion en diciembre-08, marzo y Junio de 2009. Se empleo un corazonador con area de cobertura de 0,01m2 x 10 cm y un area de muestreo de 0,04m2. Se evaluo temperatura, salinidad, transparencia, nitritos, solidos suspendidos totales y su fraccion organica, el porcentaje de materia organica y carbonato de calcio, el indice arenoso y el tamano de grano. Se identificaron 93 familias de un total de 2957 organismos. Las densidades de la macroinfauna fluctuaron entre 118 y 638 organismos/0,04 m2 pertenecientes a nueve grupos biologicos: anelidos, artropodos, cordados, equinodermos, moluscos, nematodos, nemertinos, platelmintos y sipunculidos, siendo los anelidos (poliquetos) el grupo mas abundante. El valor de biomasa humeda total alcanzo 3,751g. El analisis de similaridades ANOSIM determino que no existen diferencias en cuanto a composicion y estructura de la comunidad macrobentonica ni temporal ni geograficamente, indicando la presencia de una sola comunidad. es-ES
