Community analysis of the soft bottom megafauna (Crustacea, Mollusca) from the southeastern region of Santa Marta, Colombian Caribbean OceanDocs
Arango, C.P.; Solano, O.D..
Soft bottom megabenthic communities have been poorly studied in the Caribbean Sea. In this study we describe the structure and species composition of a Crustacea-Mollusca megafaunal community based on beam trawl samples taken between 13 and 60 m depth at the southwestern region of Santa Marta, Colombian Caribbean. Classification and ordination analyses using abundance data of crustaceans and molluscs produced two main groups (A and C), which seem to be controlled by depth and sediment characteristics. Group A consisted of species collected at the deeper stations and high content of silts (between 30 and 60 m depth) and exhibited the highest density and biomass mean values. The decapod Chasmocarcinus cilindricus was found as the characteristic species for...

Comunidades de esponjas de los arrecifes del Archipiélago Sabana-Camaguey, Cuba OceanDocs
Alcolado, P.M..
The research was carried out in order to know the sponge community composition and structure of the Archipelago Sabana-Camagüey, and to assay their use as indicators of the environmental severity and predictability, as well as of the most important stressors of this territory. For this purpose, sampling was done at stations located in 10 reef transects (between 10 and 20 m deep). Species which occurred more frequently with numerical dominance are typical of environments submitted to strong sedimentation and turbulence, which suggests that these environmental stressors and light are the main determinants of sponge community structure and composition in the studied reefs. The development of dense algal mats is also determinant in shallow stations. Species...

Coral reefs and their management in Tanzania OceanDocs
Wagner, G.M..
Coral reefs are very important in Tanzania, both ecologically and socio-economically, as major fishing grounds and tourist attractions. Numerous fringing and patch reefs are located along about two-thirds of Tanzania’s coastline. These reefs have been partially to severely degraded by human (primarily destructive fishing practices) and natural (particularly coral bleaching) causes. These immediate human causes have been brought about by various socioeconomic root causes, particularly poverty and lack of proper management. After decades of human and natural impacts there has been only limited reef recovery. This paper presents a region-by-region analysis of trends in the condition of coral reefs in Tanzania in relation to the causes of damage. While earlier...

Estudio de las comunidades del fitoplancton y zooplancton en Monteverde, Península de Santa Elena, Ecuador durante noviembre de 2006 OceanDocs
Tapia, M.E.; Naranjo, Ch..
El presente estudio se efectuó frente a la localidad de Monteverde, Península de Santa Elena, monitoreándose un total de 15 estaciones durante los estados de marea de flujo y reflujo en noviembre de 2006. Las mayores concentraciones de clorofila a: Se observó en la estación 9 en la capa superficial con valores de 0.90 mg/m3 determinándose como un área de mayor productividad y la menor concentración se registró en la estación 4 con valor de 0.10 mg/m3 durante la fase de flujo. En la comunidad fitoplanctónica se determinó dos áreas de mayor diversidad y abundancia de especies: La primera se observó en las estaciones 4 y 6 durante flujo registrándose la mayor abundancia relativa, la segunda corresponde a las estaciones 10 y 11 en reflujo. Se destaca la...

Estudio de los poliquetos bentónicos y fauna acompañante en la zona intermareal y submareal de la Bahía de Santa Elena (Ecuador) durante el año 2007 OceanDocs
Villamar, F..
Se presentan los resultados obtenidos del estudio de los poliquetos de la Bahía de Santa Elena en la zona intermareal rocosa y arenosa del Puerto de Salinas (Yacht Club), Puerto Lucía, Santa Rosa, Terminal Petrolero de la Superintendencia de La Libertad y el área de Ballenita. Del total de poliquetos identificados la especie Pareurythoe spirocirrata es la más frecuente del área estudiada y representan el 9% del total de poliquetos, prefiere vivir en la zona rocosa del área de Santa Rosa y Puerto Lucía. Del análisis de la fauna bentónica de la zona submareal del área de la Bahía de Santa Elena, se identificaron 13 especies de poliquetos bentónicos siendo la especie Capetilla sp. la más abundante (10%), seguido por la especie Sabella sp. (8%), Paraonis sp....

Villamar F., F..
Esta investigación tiene como propósito conocer la actividad biológica de la zona intermareal en el área de la costa ecuatoriana con la finalidad de determinar la taxonomía, distribución y abundancia de los poliquetos intermareales capturados en la zona estudiada, que servirán como línea de base para futuros Estudios de Impacto Ambiental (EIA) por las diversas alteraciones ambientales o contaminantes de origen antropogénica y por obras portuarias.

Etude systématique et écologique de la faune associée aux moules (<Mytilus galloprovincialis>) OceanDocs
Fezzani, S.; Zghal, F.; Ben Amor, Z.; El Abed, A..
Ce travail s’intéresse non seulement à la connaissance de la faune associée aux moules notamment : Mytilus galloprovincialis, mais aussi à une étude systématique et écologique de la faune récoltée. Cette étude a été réalisée dans le lac de Bizerte, à la station de mytiliculture de Menzel Jemil. Une partie de ce travail est consacrée à un examen systématique de la faune récoltée et qui nous a permis d’inventorier 6 embranchements dont les annélides qui sont représentés par 10 espèces de Polychètes. Nous présentons également les résultats de l’étude écologique du peuplement suivant les trois saisons: hiver, printemps, et été. Parmi les 26 taxons recensés, les Crustacés représentent environ 62%; les Polychètes avec 35% dominent très largement les autres...

Variación espacial en comunidades de esponjas de la costa oriental de Bahía de Cochinos, Cuba OceanDocs
Caballero, H.; Busutil, L.; García, Y.; Alcolado, P.M..
The sponge communities at four locations on the east coast of Bahía de Cochinos were surveyed in October 2002. At each location, sampling sites were established in the ecological zones of patch reef (3 m), shallow terrace (6-10 m), and deep terrace (15 m). The line-transect method with a 10 m line as sampling unit was used to measure sponge bottom coverage, and a 1 m square grid was used to quantify sponge community density. Species heterogeneity and species richness indices showed variability among sites and tended to increase with depth. Thirty species belonging to 19 families and 21 genera were found. The most common species were: Mycale laevis, Aplysina cauliformis, Cliona aprica, Aplysina fistularis, and Ectyoplasia ferox, which comprised 48% of the...
