Con el fin de colectar octocorales telestáceos y penatuláceos se revisaron diferentes ecosistemas entre O y 30 m de profundidad, mediante buceo SCUBA y simple a pulmón que comprendían litorales rocosos, fondos arenosos y arrecifes coralinos, en un área que incluye a Cartagena, las Islas del Rosario, Tierra Bomba, Barú y San Bernardo, los bancos de Salmedina y Bushnell, las ensenadas de Zapzurro y Capurganá (8°20'-10°45' N; 75°50'-77025' W), en la región de Santa Marta (11°14'50" N; 74°15' W) y la Guajira (11°56'58" N; 72°16'18" W), en el Caribe colombiano. Se encontró por primera vez en el mar Caribe y la costa colombiana a Sfy/afu/a diadema Bayer (Virgulariidae: Pennatulacea) que se halló solamente en fondos arenosos blandos entre 25 y 30 m a la salida de... |

The effects of habitat characteristics (mangrove creek, sandflat, mudflat and seagrass meadow) water salinity, temperature, and depth on the density, spatial distribution and size distribution of juveniles of five commercially important penaied shrimp species (Metapenaus monoceros, M. stebbingi, Fenneropenaeus indicus, Penaeus japonicus and P. semisulcatus) were investigated during a high shrimp recruitment peak lasting from January to June 2002, in four contiguous habitats within a non-estuarine mangrove bay at Saco da Inhaca, Inhaca Island, Southern Mozambique. A total of 14,976 specimens representing the five species were collected by means of a 1m beam-trawl fitted with a 2 mm mesh net with a cod-end. Every two weeks corresponding with spring tides on... |

Se describe la distribución y la ecología de las 2 especies del gen. Voluta Linné, 1758, V. Virescens y V. Musica, V. Virescens se encuentra entre Wounta Haulover, Nicaragua, y Taganga, es habitante de fondo suave y vive en fango, arena fina y arena con cal coralina, desde agua seca hasta más o menos 90 Mts. de profundidad. V. Musica se halla en la parte este y sur del mar caribe, y en Colombia va hacia el oeste hasta la ensenada de Chengue. Vive en arena coralina y calcárea y parece que evita arena mineral y fango. Su distribución vertical es desde agua seca hasta 30-40 mts. de profundidad. Ambas especies viven completamente enterradas y se alimentan de gasterópodos y otros invertebrados, además de carroña. Se describe y figura la radula de V. virescens.... |

Le golfe de Gabès situé au sud-est de la Tunisie, est la région où l’activité de pêche est la plus développée du pays. L’intensité de cette activité a eu des conséquences négatives sur l’écosystème (diminution de la productivité, changements dans la composition spécifique des assemblages, recul du couvert végétal etc…) qui, par ailleurs, est le siège d’une pollution importante et où le changement global se fait de plus en plus ressentir. Il est maintenant démontré que le changement global ne peut pas être sans impact sur le fonctionnement des écosystèmes. Cependant, jusqu’à aujourd’hui, aucune étude n’a démontré d’une manière objective les modifications qui pourront avoir lieu dans l’écosystème du golfe de Gabès suite à ces changements. Ce travail a donc... |

A new species of the previously monotypic catfish genus Phreatobius is described from an artificial well in the village of Rio Pardo, located 90 km south of the city of Porto Velho, State of Rondônia, Brazil, in the drainage area of the Rio Branco (Rio Madeira system, Amazon basin). Phreatobius dracunculus n. sp. differs from its only congener, P. cisternarum, by the absence of eyes (vs. present), the lack of dark integumentary pigmentation (vs. faint dark pigment always present), the presence of five pectoral-fin rays (vs. four), ventral procurrent rays 11-13 (vs. 22 to 26), dorsal procurrent rays 29-31 (vs. 42 to 50), fewer vertebrae (52 or 53 vs. 59 to 64) and the larger pseudotympanus. The new species shows all diagnostic characters so far proposed for... |

A very large collection of Naididae of the West Indies (153 localities), Suriname (15), Venezuela (2) and Florida (1) is studied. Five new species Nais barua, Dero scalariformis, D. tuna, Aulophorus kalina, A. barbatus are described. Dero magna, D. trifida, Aulophorus tridentatus, Allonais japonica, Pristina sima are redescribed. The 46 Naididae species of the West Indies are discussed by their taxonomy, distribution and habitat. |
