| Benthic macrofauna and meiofauna distribution patterns were described in a tropical coral reef (Punta Francés, Cuban Archipelago, Caribbean Sea). Density and main taxa composition for macrofauna and meiofauna and species diversity and organismal traits for free-living nematodes were compared among four habitats: seagrass bed, sand flat, dead coral and hard bottom. Strong spatial patterns of distribution across habitats were detected and explained by a complex combination of habitat features. Signal/noise ratio for macrofauna data of distribution was enough strong to detect changes across habitats but the sizes of sampling devices were not adequate to represent the real patterns in the nature. Meiofauna patterns of distribution were driven by the... |

| The structure of meiofaunal communities was surveyed in 17 stations in Nipe Bay, Cuba in July, 2001. Levels of Nickel (all stations) are higher than in several bays in Cuba, probably due to natural causes. The levels of Copper, Zinc, Fe and Manganese indicate a relative low pollution, likely related to the presence of urban settlements. There is decrease in the total density and number of taxa of meiofauna in the stations with higher levels of metals; the copepods appear to be particularly sensitivity to metal pollution. The stations located at the mouth of the bay have the lowest levels of contamination and the highest total density of organisms and taxa richness, probably due to a more intense turnover of the waters in this area and consequent lower... |
