| The spatial and temporal changes of the fish assemblage areas composition at the coastal ecosystem of the western South Atlantic (34 degree -41 degree S) during six springs (1981, 1983, 1994, 1995, 1998 and 1999), were examined. For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns. In order to determine how the environmental factors influenced the fish community structure, the... |

| In this paper, we report the isolation and identification of 45 marine bacterial strains from waters of the Southern Economic Exclusive Zone of Cuba collected during three cruises carried out between 1989 and 1991. The antimicrobial activity was determined by the diffusion plate method using Nutrient agar and agar blocks with the cultures to study. As result, 24 species were identified and 9 resulted new reports for Cuban waters. The highest percentage was obtained for Gram-positive bacteria, particularly spore-forming bacteria (67 %). Arthrobacter, Halorubrum and Lactobacillus genus were new reports for oceanic waters. Antibacterial activity was more represented than antifungal activity among the tested strains. Gram-positive bacteria showed high... |

| Durante la VIII Expedición Antártica se realizaron observaciones diarias en Punta Fort Williams, con el objetivo de determinar las especies de aves presentes, el número de especies que anidan en este sitio y la población existente de cada una de ellas. Según los resultados obtenidos se encontraron 10 especies. Macronectes giganteus (Petrel gigante del sur), Catharacta lonnbergi (Skua subantártica), Catharacta maccormicki (Skua antártica), Larus dominicanus (Gaviota dominicana), Oceanites oceanicus (Golondrina de mar común), Sterna vitata (Gaviotín antártico), Pysgoscelis papua (Pingüino papua), Pysgoscelis antártica (Pingüino barbiquejo), Daption capense (Petrel del cabo) y Phalacrocorax atriceps (Cormorán antártico), de las cuales las cinco primeras... |

| Se evaluaron 11 sitios de buceo de los arrecifes de “María la Gorda”, costa suroccidental de Pinar del Río, Cuba, en diciembre del año 2003. Se empleó el método del marco cuadrado de 1m de lado. Se encontraron 35 especies de corales pétreos. Las más abundantes fueron Agaricia agaricites, Siderastrea siderea, Porites astreoides, Montastraea franksi y M. faveolata. Los índices de riqueza de especies, heterogeneidad, y equitatividad fueron moderadamente altos a altos, lo que sugiere condiciones ambientales favorables y casi constantes. La densidad por estación resultó moderadamente alta e igualmente indica buenas condiciones para los corales pétreos. La comparación de los datos obtenidos en los sitios de buceo con la estación de referencia sugiere que no ha... |
