Ovigerous females of Libinia spinosa were collected in the oceanic region adjacent to the Patos Lagoon and were maintained in the laboratory at 20° and 30 PSU until spawning. After hatching larvae were transferred to ...

The accumulation of high biomass of diatoms in the surf zone is a characteristic feature of some sandy beaches where the wave energy is sufficiently high. A few species of diatoms, called surf diatoms, thrive in this ...

O presente artigo apresenta a aplicação do aporte analítico dos sistemas agroalimentares associado à Sociologia Econômica na análise de questões afeitas à pesca artesanal, tendo como perspectiva uma abordagem sistêmica e ...

In many cases in large urban centers, which have appropriate waterbodies, small-scale fisheries are the only source of cheap protein for the poor. In Lago Paranoá, located in Brasília, the capital city of Brazil, fishing ...

The biodiversity of marine heterotrophic protists is poorly known in the South Atlantic coastal zone (~32 °S) especially regarding the nanoflagellates. The presence of loricate choanoflagellates was reported ...

The palaeoenvironmental history has been studied based on palynology of a sedimentary profile from the Alpes de São Francisco bog (29290 3500S, 50370 1800W), São Francisco de Paula municipality, Rio Grande do Sul eastern ...

(Palynomorphs of the sedimentary profile of a bog, São Francisco de Paula, Eastern Plateau of Rio Grande do Sul, southern Brazil). This paper aims at giving basic reference material to the study of plant succession in the ...

In this study it was hypothesised that increasing water retention time promotes phytoplankton blooms in the shallow microtidal Patos Lagoon estuary (PLE). This hypothesis was tested using salinity variation as a proxy ...

(Pollen of gymnosperms and angiosperms of the sedimentary profile of a bog, São Francisco de Paula, Eastern Plateau of Rio Grande do Sul, southern Brazil). This pollen catalogue aims at helping the study of paleoenviron ...

In this work, fossil assemblages of coccolithophorids, oxygen stable isotopes (Globigerinoides ruber), and radiocarbon dating were used as proxies. The sediment core, obtained on the slope of Campos Basin, was analyzed, ...

(Magnoliopsida (Asteridae) and Liliopsida pollen of the sedimentary profile of a bog, São Francisco de Paula, Eastern Plateau of Rio Grande do Sul, Southern Brazil). This paper aims to provide data for paleopalynological ...

This study aimed to evaluate the contribution ofthree diatom species on the lipid content of bio-flocs, their permanence on the bioflocs and influ-ence on the growth performance of juvenileshrimps. Juveniles of Litopenaeus ...

This study aimed at identifying morpho-species of microplankton dinoflagellates (> 20 μm) of the order Peridiniales and Prorocentrales off Santa Marta Grande Cape, CSMG (SC, 28º 40’ S) and Albardão-Chui, AC ( r S, ...

Aquaculture generates a large load of effluents richin organic matter and nutrients that may be intro-duced into the environment. This study aimed toassess in a microcosm experiment, the effect ofshrimp pond water mixed ...

Seasonal and interannual changes (1993e2012) of water temperature and transparency, river discharge, salinity, water quality properties, chlorophyll a (chl-a) and the carbon biomass of the main taxonomical phytoplankton ...

To understand the mechanisms that trigger changes in chlorophyll a and species composition in the phytoplankton of the surf-zone at Cassino Beach (RS), we performed two short nutrient-enrichment experiments (4–5 days ...

Bio-floc shrimp culture systems have been investigated in an attempt to optimize water use and prevent the discharge of effluent into the environment. The importance of microalgae in maintaining water quality and nutrition ...

This paper provides information on the morphology and occurrence of extant diatoms of the family Asterolampraceae and Azpeitia species of the southernmost Brazilian continental shelf and slope waters in the Southwestern ...

Dados batimétricos detalhados obtidos na antepraia adjacente ao Molhe Oeste conhecida como banco das Três Marias, evidenciaram a presença de uma fossa junto a extremidade do molhe e um banco na forma de domo a SO da ...

Gel permeation chromatography method was applied to evaluate the Zn metal distribution levels in the organic fraction from sediments collected in the Patos Lagoon estuary. The analysis was performed based in metal distribution ...
