| The transfer of 210Po and 210Pb in the food web of small pelagic fishes (from phytoplankton and zooplankton to anchovy Engraulis encrasicolus and sardine Sardina pilchardus) is investigated in the Gulf of Lion (GoL). We present original data of 210Po and 210Pb activity concentrations, C and N stable isotope ratios, measured (i) from different size classes of phytoplankton and zooplankton during spring and winter in different environments of the GoL, and (ii) in two fish species. Significant spatial patterns based on 210Po, 210Pb activity concentrations and 210Po/210Pb ratios in the different plankton size classes are evidenced by hierarchical clustering, both in spring and winter. This variability, also observed for C and N stable isotopes ratios, is... |

| Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR research has been integral to advancing understanding of plankton dynamics and informing policy and management decisions. We describe how the CPR can contribute to global plankton diversity monitoring, being cost-effective over large scales and providing taxonomically resolved data. At OceanObs09 an integrated network of regional CPR surveys was envisaged and in 2011 the existing surveys formed the Global Alliance of CPR Surveys (GACS). GAGS first focused on strengthening the dataset by identifying and documenting CPR best practices,... |

| Los ensambles zooplanctónicos en cuerpos de agua de la zona centro y sur de la Patagonia chilena se caracterizan por su alto endemismo y un relativo bajo número de especies lo cual se debería principalmente a la oligotrofía y niveles de conductividad de estos ambientes. El objetivo del presente trabajo consistió en analizar información publicada y sin publicar sobre crustáceos zooplanctónicos en lagos y lagunas de la zona central y sur de la Patagonia (44 - 53g S). A estos datos se les estimó la razón especies / género, y se aplicó un modelo nulo basado en co-ocurrencia de especies mediante una matriz de presencia y ausencia de especies, con la intención de determinar ausencia de factores reguladores de las asociaciones de especies. Dentro de este mismo... |

| The influence of tidal and diel changes on the exchange of Petrolisthes armatus planktonic larvae was studied at the Catuama inlet, which represents an intermediate system of marine and estuarine environments in the Northeast Brazil. To characterize the larval abundance and vertical distribution, samplings were carried out in August 2001 at neap tide and 3 stations, with 3 hours interval over 24 hours. Samples were taken at three or two depths at each station, with a plankton pump coupled to a 300 µm mesh size net. Petrolisthes armatus zoea I and II showed a mean of 26.3 ± 83.6 and 12 ± 38.8 ind m-3, respectively. During flood tides, the larvae were more concentrated in the midwater and surface, which avoided the transport to internal regions. In contrast,... |

| El embalse Rapel, es un cuerpo de agua que está siendo sometido a un fuerte impacto antropogénico, por lo que evidencia severos signos de eutrofización. Esto último debido a que el embalse se ha transformado en el cuerpo receptor de una gran diversidad de efluentes (industriales, agrícolas y domésticos), que evacuan sus descargas sin ningún tipo de tratamiento. A lo cual se le debe agregar la recepción de aguas provenientes de los relaves de la mina de cobre “El Teniente”. Con el objetivo de determinar la presencia y acumulación de metales pesados en el agua y en los organismos zooplanctónicos, durante el mes de Octubre del 2003 se tomaron muestras de agua y de ejemplares de Ceriodaphnia dubia, Bosmina chilensis y Diaptomus diabolicus. Como especies... |

| El presente trabajo corresponde al análisis de zooplancton colectado en cinco estaciones localizadas en el río Guayas. La primera estación estuvo situada 10 km. río arriba de la confluencia del río Babahoyo con el río Daule, en un pozo acuífero. Las otras estaciones se situaron en cuatro sitios consecutivos a lo largo del río Guayas. En este trabajo se han identificado 10 especies: Brachionus plicatilis (O. F. Muller) (Rotifera), Alona cambouei Guerne and Richard, 1893; Moina micrura Kurz, 1874 (Cladocera); Acartia tonsa Dana, 1848; Oithona dissimilis Linberg, 1940; Oithona neotropica Herbs, 1967; Oithona oligohalina Fonseca o Bjornberg, 1976; Mesocyclops longisetus (Thiebaud, 1914) y Pseudodiaptomus longispinosus Chad, 1989 (Copepoda). Las especies... |

| Zooplankton biomass was measured at 20 stations located along five coastal-offshore transects in the Gulf of Lions (NW Mediterranean) during spring 1998 and winter 1999, using two nets equipped with 200 and 80 Pm mesh. Biomass was twice as abundant in spring. It increased toward the coast and the west of the gulf and was positively correlated to chlorophyll, primary production and organic particulate matter and negatively to temperature and salinity. The enrichment effect of Rhone river input and the oligotrophic influence of the north Mediterranean current (NMC) were the main distribution factors of zooplankton biomass. Higher biomass was obtained in coastal stations with the 80 mum net, which sampled more efficiently young larval stages and nauplii.... |

| El objetivo de la presente investigación, fue dar un comprensivo entendimiento de las condiciones bio-oceanográficas del fitoplancton-zooplancton-ictioplancton, y las interacciones con el medio circundante (físico, químico), procesos que son complicados cuando involucran aspectos hidrográficos costeros como áreas de afloramiento, áreas de pesca y áreas de soporte alimentario para los diferentes recursos marinos costeros planctónicos-bentónicos y aves-mamíferos marinos. |

| A Nutrients-Phytoplankton-Zooplankton-Detritus (NPZD) ecosystem model is coupled to the Miami Isopycnic-Coordinate Ocean Model (MICOM) to study planktondynamics in the Arabian Sea. Experiments oriented to testing the NPZD-MICOM coupled model sensitivity to variations in several parameters are performed. Particular attention is paid to the rates of detritus sinking and maximum phytoplankton growth rate. The coarse features of the blooms are captured by all the experiments considered, and agree with earlier models for the biological activity of the region. Intensity, duration, and peaks of the blooms are found to be quite sensitive to the parameter choices. The existence of an offshore deep chlorophyll maximum in the model is found to be closely related to... |
