| This study evaluated the efficiency as a tool for ant survey of a sampling protocol composed of six methods, and examined the role of environmental features on the efficiency of methods complementarity . We applied them in three environments (pine, eucalyptus and native forest) in the National Forest of Chapecó and the effect of the characteristics of these environments on methods complementarity. The sampling methods were pitfall traps, two types of bait (sardines and glucose), sweep net, entomological umbrella and Malaise trap. The protocol efficiency of the protocol in the ant inventory was evaluated based on rarefaction curves, richness estimators and records of occurrence of ants. The protocol captured the greatest richness on native forest... |

| A quantitative approach is presented to evaluate fatty acid incorporation in fish. Fatty acid composition of European sea bass juvenile was studied during an experiment using 6 isoproteic (54%) and isolipidic (18%) diets containing 0.23, 0.56, 0.72, 0.86, 1.01 and 1.86% DM n-3 highly unsaturated fatty acids (n-3 HUFA). Whole body fatty acid compositions were studied at the beginning and after 52 and 81 days feeding, fatty acid profiles evolved during time under dietary influences. Incorporations of individual fatty acids into total lipids were calculated as increases in individual fatty acids as percentages of the increase in total fatty acids during growth, on a per animal basis. Relative incorporations (RI) so defined generated similar profiles for the... |

| Depuis son introduction en Bretagne, au début des années 70, peu d'études ont été consacrées à l'huître creuse Crassostrea gigas sur cette région, sauf lors de pollutions (Amoco Cadis) ou d'anomalies de croissance de la coquille. En l'absence de données récentes, des stations expérimentales "d'élevage" ont été mises en place sur 8 sites conchylicoles bretons. Un lot d'huîtres de "18 mois" est réparti en début d'année dans 96 poches, à raison de 6 poches par station et 2 stations par site. Des mesures de biométrie, de composition de la chair, d'lindex de qualité, de taux de survie, et de parasitisme sont réalisées après 7 mois d'élevage. Après étude des résultats variable par variable, une analyse descriptive par A.C.P. montre 6 groupes de sites ou stations... |

| We studied the amino acid (AA) composition of the floral nectars of 73 plant species occurring in a phryganic (East Mediterranean garrigue) community and investigated whether AA and sugar composition is shaped by evolutionary (plant phylogeny), ecological (flowering time as a direct effect of summer drought) and coevolutionary (pollinator partnership) constraints. Our study utilised an extensive plantpollinator matrix compiled in the same area where the plants had been sampled. Using HPLC we detected 22 AA compounds/groups of compounds, out of which 15 were commonly present in almost all nectars. Among all AAs, phenylalanine was the most abundant, especially in keystone (ââcornucopianââ) plant species visited by many insect species, such as the... |

| This work includes the composition and distribution of phytoplankton in the coastal region. For this purpose were established 23 stations on three regions and six sections divided from the northern region of Esmeraldas to the south of Puerto Bolívar, this work was carried out at the Research Vessel Orión in december 2008. The greater diversity of the phytoplankton community in the surface layer was observed in the Central Region, Specifically in section 4 with a total of 84 species, highlighting the dominant species of diatoms as Rhizosolenia stolterfothii, Thalasssiosira subtilis, R. imbricata, Proboscia alata, Chaetoceros affinis, and in the group there were abundant dinoflagellates Gonyaulax poledra and Goniodoma polyedricum, characteristics of the... |

| The main objectives of the survey were the following: • To map the distribution and estimate the abundance of the most commercially important pelagic species in the Namibia-Angola transboundary area (15°50-19°00’), following the survey design utilized in Angolan waters (6 n.mi spacing between transect lines), with special emphasis on the two horse mackerel Cunene horse mackerel (Trachurus trecae) and Cape horse mackerel (Trachurus capensis), sardine “Pilchard” (Sardinops sagax) and other small pelagic species, including anchovy (Engraulis capensis) and round herring (Etrumeus whiteheadi). • To map the distributions and estimate the abundance of the same species in central Namibia south to Dune Point (20°15’ S), following the established survey design with... |

| Durante el verano austral, se efectuó la VII Expedición Antártica Ecuatoriana, a bordo del B/I Orión, perteneciente a la Armada del Ecuador. Entre los meses de enero y febrero de 1998, en la Ensenada Guayaquil y Bahía Chile (Isla Greenwich), se colectaron y analizaron muestras de macrozooplancton obtenidas de arrastres superficales con redes tipo cónica simple de 500μ m, con la finalidad de conocer la distribución y composición del zooplancton. Las salpas fueron los organismos más representativos con el 46%, en segundo lugar estuvieron los copépodos 17% y quetognatos 15%, en la Ensenada Guayaquil donde también se presentó la mayor heterogeneidad zooplanctónica, registrándose la mayor distribución al oeste, próximo a la Isla Dee. En Bahía Chile, la... |

| Tortuguilla is a small island off the southern portion of the Colombian Caribbean continental coast. It is surrounded by a shallow calcareous shelf which is overgrown by recent coral formations whose distribution, composition and zonation are herewith qualitative described for the first time. Observations and data collecting were conducted during two days from a boat by snorkeling at 63 stations and along manta tow transects. Despite the reduced area and the adverse turbidity and sedimentation conditions, at least 16 species of stony corals were registered (4 more to be confirmed), being Millepora spp. and Siderastrea siderea the most common. Five different coral assemblages were recognized. |

| El presente trabajo comprende la composición y distribución del plancton en las Islas Galápagos. Para el efecto se establecieron 12 estaciones ubicadas en las secciones 83°- 86°-89° y 92°W, realizadas en septiembre del 2011. Se identificaron 71 especies de fitoplancton en muestras de red (50µ). Las diatomeas fueron dominantes y en menor concentración se observaron los Dinoflagelados, Cocolitofóridos, Silicoflagelados, Cianobacterias y Tintínnidos. En las muestras de red se observaron Chaetoceros eibenii, Rhizosolenia imbricata, Thalassiosira subtilis, Proboscia alata y Planktoniella sol características del Frente Ecuatorial en la sección 86°W y 02° sur. En zooplancton se registraron 17 taxa zooplanctónicas destacándose los grupos de Radiolarios 47.5%,... |
