37. Faecal bacteria in Perna perna (Linnaeus, 1758) (Mollusca: Bivalvia) for biomonitoring coastal waters and seafood quality
O desenvolvimento urbano em áreas costeiras é intenso e o aumento das descargas de esgoto é uma das conseqüências. Assim, leis específicas que regulem limites para a contaminação microbiológica das águas e de alimentos de origem marinha são necessárias. O objetivo deste estudo é avaliar a utilização de Enterococos e coliformes termotolerantes

38. Seasonal variation of macromedusae (Cnidaria) at North Bay, Florianópolis, southern Brazil
Seasonal variation of large medusae abundance and biomass was studied in the North Bay, Santa Catarina, southern Brazil (27°30'S, 48° 32'W), from February to December 2005. Collecting was conducted seasonally with the help of fishing bottom trawl in 30-minute sections (12 in summer, 18 in each of the remaining seasons) in six stations, totaling 66 samples.

39. Possible influence of the ENSO phenomenon on the pathoecology of diphyllobothriasis and anisakiasis in ancient Chinchorro populations
Current clinical data show a clear relationship between the zoonosis rates of Diphyllobothrium pacificum and Anisakis caused by the El Niño Southern Oscillations (ENSO) phenomenon along the Chilean coast. These parasites are endemic to the region and have a specific habitat distribution. D. pacificum prefers the warmer waters in the northern coast, while An

41. Variabilidade interanual (10 anos) da comunidade zooplanctônica na região costeira do Espírito Santo, em área sob influência de efluente industrial aquecido
In the last decade (1998-2007) collections were made of biotic (zooplankton) and abiotic (temperature and salinity) in the coastal waters adjacent to Praia Mole, in the Espírito Santo, in order to monitor the potential effects of disposal a heated effluent on the zooplankton community. This study aimed to analyze the data generated by this monitoring by obs

42. Virioplankton Abundance in Trophic Gradients of an Upwelling Field
This work correlates time series of biological and physical variables to the marine viruses across trophic gradients within Arraial do Cabo upwelling system, Southeast of Brazil. The objective is to investigate the major controlling factors of virioplankton dynamics among different water masses. It was used an in situ and ex situ flow cytometry for accessing

43. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

44. Capacidade de Retenção de Fósforo e Material Particulado em Suspensão por Manguezal de Área Impactada por Efluentes da Carcinicultura. / Phosphorus retention capacity and Suspension of Particulate Matter in Mangrove Area impacted by effluents from Shrimp.
The mangrove forests stabilize the coastal erosion zone and act as a buffering between the continent and the sea. This forest presents high resilient degree, suggested to be used as marker of environmental changes. They play an important role in the energy flow and nutrients cycles. They are suffering with the growth of shrimp ponds. This tends to be respons

45. Resposta da Plataforma Continental Sudeste a ventos sazonais e sinóticos de verão: estudos numéricos / Response of the South Brazil bight to summer seasonal and synoptic winds: numerical studie
In order to study the pertubations caused on the South Brazil Bigth (SBB) caused by the passage of a cold front during Summer, a mean basic state for currents was obtained using the POM (Princeton Ocean Model) through diagnostic simulation, followed by a short round prognostic. The mean currents modeled are in certain instancies similar to the currents measu

46. Estudo da circulação hidrodinâmica e da dispersão de óleo na zona costeira entre Macau e Galinhos RN
This paper presents a study on coastal hydrodynamics and the spread of an oil spill in waters off Macau and Galinhos, on the east coast of the state of Rio Grande do Norte in Northeast Brazil. This area has a very marked coastal dynamic owing to the complexity of its geomorphological features, developed in a regime of semidiurnal mesotides involving reefs, s

47. AvaliaÃÃo ambiental e percepÃÃo dos usuÃrios sobre os efeitos das obras de proteÃÃo de costa nas praias da Casa Caiada (Olinda) e Janga (Paulista)
The coastal zones and special the beaches are dynamical and fragile regions in a continuous change. The high population concentration in these areas results in a pressure increment upon natural resources and increased risk of environmental degradation. The coast of the Sate of Pernambuco, is experiencing coastal erosion that has many times being mitigated wi

48. Ecologia parasitária de isópodos e biologia reprodutiva em tibiro, Oligoplites spp (OSTEICHTHYES: CARANGIDAE) das águas costeiras de Natal, Rio Grande do norte
Oligoplites palometa (Cuvier) and Oligoplites saurus (Bloch &Schneider) (Osteichthyes: Carangidae) are coastal pelagic fish species. The objective of this study was to investigate the effect of parasitism by isopods and the reproductive biology of the leather jack, Oligoplites spp. A total of 113 individuals of Oligoplites spp (35 of O. saurus and 78
