ASPECTOS DE LA BIOLOGÍA DE PORTUNUS SPINICARPUS STIMPSON 1871 (DECAPODA: PORTUNIDAE) EN EL GOLFO DE SALAMANCA, CARIBE COLOMBIANO Boletín de Investigaciones
García,Camilo B.; Mendoza,Nardi.
Some vital statistics of the population of Portunus spinicarpus inhabiting the Golfo de Salamanca, Colombian Caribbean, are presented for the first time. Condition factor was found stable the year round, Von Bertalanffy growth parameters were estimated as L¥=38.6 mm, K= 2.5 year-1, to= -0.0573 year. Natural mortality was estimated as 4.62 year-1. P. spinicarpus seem to prefer deep waters and sand-muddy bottoms.

DYNAMICS OF A MACROALGAL ROCKY INTERTIDAL COMMUNITY IN THE COLOMBIAN CARIBBEAN Boletín de Investigaciones
García,Camilo B.; Díaz Pulido,Guillermo.
The macroalgal intertidal community at a tropical location (Punta de la Loma, Colombian Caribbean) was monitored at irregular intervals from 1992 to 1995. The highly diverse macroalgal community was relatively invariant in cover, taxa and biomass from small spatial scales (square centimeters). At larger spatial scales (square meters), however, there was a small but definitive seasonal pulse in dominance and composition. Sand intrusions over the rocky intertidal represents a b disturbance reducing macroalgal cover during the dry season. Interannual variation was also detected. La Punta de la Loma appears to be influenced by the regional upwelling conditions.

ENSAYOS DE ACTIVIDAD BIOLÓGICA Y ECOLOGÍA QUÍMICA DE EXTRACTOS ORGÁNICOS DE MACROALGAS DEL CARIBE COLOMBIANO Boletín de Investigaciones
Díaz R.,Martha Cecilia; Bula Meyer,German; Zea,Sven; Martínez,Alejandro.
This study evaluates the biological activity and possible deterrance played by organic crude extracts from six Phaeophyta and two Rhodophyta algae from Southern Caribbean. Bioessays were carried out using concentrations equivalent to those present in algae tissue. Species in general did not show high citotoxic activity. However Dictyota pulchella, showed a delay in the mitotic process for cells stage XVI. Extracts from Dictyota bartayresiana, D. pulchella, Sargassum cymosum and Cladophyllum schnetteri, inhibited S. partitus feeding under laboratory conditions. Nontheless, only extracts from D. bartayresiana and C. schnetteri showed this activity in the field.

EVALUACIÓN RÁPIDA DE LOS EFECTOS DEL HURACÁN BETA EN LA ISLA PROVIDENCIA (CARIBE COLOMBIANO) Boletín de Investigaciones
Rodríguez-Ramírez,Alberto; Reyes-Nivia,María Catalina.
Hurricane Beta passed very close to Providencia and Santa Catalina islands in October 29, 2005 as a moderate category 1 hurricane. Fast surveys carried out fifteen days after the event at 20 sites located on coral reefs, seagrass beds, beaches, and mangroves indicated a low impact over these four ecosystems. In contrast, terrestrial vegetation and island’s infrastructure were severely damaged.

LA CLASE CAUDOFOVEATA (MOLLUSCA) EN EL MAR CARIBE COLOMBIANO* Boletín de Investigaciones
Gracia C.,Adriana; Fontalvo,Erlenis; Gámez,Luis Carlos.
Five classes of marine mollusks, including Gastropoda, Bivalvia, Cephalopoda, Scaphopoda, and Polyplacophora, have been recorded inhabiting the Colombian Caribbean Sea. Other classes with a basal position within the phylum such as Caudofoveata and Solenogastres have remained overlooked, as a result of their body shape (worm-like with no shell), small sizes (Caudofoveata 1.5 to 140 mm length), and limited taxonomic information for identifications. The presence of Caudofoveata species on the continental margin of the Colombian Caribbean Sea was evidenced through several studies conducted by Invemar between 2007 and 2012. Samples were collected from localities between Gulf of Morrosquillo and La Guajira, in a bathymetrical range from 3 to 1010 m depth. These...

MOLECULAR PHYLOGENY OF THE NERITIDAE (GASTROPODA: NERITIMORPHA) BASED ON THE MITOCHONDRIAL GENES CYTOCHROME OXIDASE I (COI) AND 16S RRNA Acta biol.Colomb.
QUINTERO-GALVIS,JULIAN; RAQUEL-CASTRO,LYDA.
The family Neritidae has representatives in tropical and subtropical regions that occur in a variety of environments, and its known fossil record dates back to the late Cretaceous. However there have been few studies of molecular phylogeny in this family. We performed a phylogenetic reconstruction of the family Neritidae using the COI (722 bp) and the 16S rRNA (559 bp) regions of the mitochondrial genome. Neighbor-joining, maximum parsimony and Bayesian inference were performed. The best phylogenetic reconstruction was obtained using the COI region, and we consider it an appropriate marker for phylogenetic studies within the group. Consensus analysis (COI +16S rRNA) generally obtained the same tree topologies and confirmed that the genus Nerita is...

POPULATION STRUCTURE OF GRENADIER FISH COELORINCHUS CAELORHINCUS IN DEEP WATERS OF THE COLOMBIAN CARIBBEAN COAST Boletín de Investigaciones
Paramo,Jorge; Motta,Jasney; Hoz,Javier De La.
ABSTRACT The objective of the study is to describe the patterns of spatial distribution and size structure of Coelorinchus caelorhincus in deep-sea waters of Colombian Caribbean. The samples were collected with trawling in depths between 200 and 550 m. Statistically significant differences in the sizes of the sexes were found, indicating sexual dimorphism. The length structure by depth strata showed a size increase with depth for both females and males. The length at sexual maturity in females was 17.238 cm TL. The spatial distribution indicates that in the northeastern area the higher aggregations were off the coast of the Magdalena River, off Santa Marta and Riohacha cities. In the southwestern area the higher aggregations were towards the northern part...

López,Tomás; Santodomingo,Nadiezdha; Reyes,Javier.
A large number of branches from the scleractinian coral Madracis myriaster, collected in deep waters of the Colombian Caribbean, showed both inside and around the skeleton calcareous structures constructed by tubiculous organisms. Here, based on the growth strategy of the coral and the physical conditions of deep-water areas, we describe the functional effect of the tube structures on deep coral frameworks formation and growth.

PRESENCIA DEL PEZ LEÓN PTEROIS VOLITANS (LINNAEUS) EN EL MANGLAR DE LA BAHÍA DE CHENGUE, CARIBE COLOMBIANO* Boletín de Investigaciones
Arbeláez M.,Natalia; Acero P.,Arturo.
Oil August 25th, 2010, four specimens of the invasive lionfish Pterois volitans were seen inhabiting the submerged roots of mangroves bordering the entrance to the southern lagoon of Bahía de Chengue, at the Parque Nacional Natural Tayrona. One specimen (40 mm total length) was captured and photographed. The occurrence of this deleterious fish in such an ecological and economic valuable ecosystem is considered potentially dangerous.

PRIMER REGISTRO DE PLAGIODISCUS NERVATUS GRUNOW (BACILLARIOPHYCEAE) EN LA REGIÓN COSTERA DEL CARIBE COLOMBIANO* Boletín de Investigaciones
Arbeláez M.,Natalia; Vidal,Luis Alfonso.
The presence of the species Plagiodiscus nervatus is reported for first time in the Colombian Caribbean coastal sea. Three specimens were found, two cells in Bahia Gaira on August 2000 and 2001 in surface samples, the other cell in Bahía Chengue on May 2012 at 2 m deep. The observations showed two particular forms of the species, one with nervature and the other without it, both larger in sizes compared with those reported by other authors for the Caribbean Sea and elsewhere in the world. It is extremely important to report additional species to complement and perform inventory and lists of the species present in the area.
