| In West Africa (between Ivory Coast and Sénégal), estuarine environments vary from lagoons to high discharge rivers to inverse hypersaline estuaries. This results in a high diversity of estuarine fish species, with an important turnover and a core of ubiquitous species. The species richness of a given estuary depends on the combination of hydrological factors (marine or freshwater dominance) and biogeography (continental biogeographic regions). The catch rate is higher in lagoons and inverse estuaries than in normal estuaries, which can be explained by the predominance of small juveniles in the latter. Clupeids are the most abundant fishes all over the region, but different systems have different dominant species. Assessing the functioning of West-African... |

| Se describen ejemplares de cuatro especies de octocorales de la familia Chrysogorgiidae (Chrysogorgia desbonni, C. elegans, C. thyrsiformis y Trichogorgia lyra) recolectados en el Caribe colombiano durante las exploraciones INVEMAR-Macrofauna I y II. Las tres especies de Chrysogorgia se encontraron entre 160 y 516 m de profundidad, mientras que T. lyra se recolectó en aguas someras entre 20 y 150 m de profundidad, ámbitos batimétricos anteriormente poco estudiados en el país, por lo que es un estudio de particular interés. Además se han identificado alrededor de 50 especies de diferentes octocorales a partir de este tipo de estudios. Chrysogorgia thyrsiformis se registra por primera vez en el Caribe colombiano. Por otro lado, se comenta... |

| In 1998, coral reefs of Tanzania were severely affected by bleaching. The coral mortality that followed caused a concern for coral reef degradation and overall resource depletion. In this study, we investigated coral bleaching effects on the coral reef fauna at Tutia Reef in Mafia Island Marine Park, Tanzania. Corals from adjacent reef patches of the species Acropora formosa were transplanted into plots, and reef structure and associated fish assemblages were examined before and after the bleaching event. Following the coral bleaching, 88% of all corals died. A year after the event, a large proportion of the dead corals was still standing. As surviving and dead corals were from different clones, results suggested that genetic variation might influence... |
