This study investigated the body copper accumulation in the amphipod Gammarus sp.. Groups of copper-binding proteins were also investigated considering their molecular weights. Regarding copper accumulation, a saturation ...

Tendo em vista que as populações de Jenynsia multidentata Jenyns, 1842 aparentemente atingem maiores comprimentos na região estuarina da Lagoa dos Patos quando comparadas com o ambiente límnico adjacente, foi realizado um ...

Taim Hydrological System is a unique subtropical wetland in southern Brazil harboring an exceptional biological diversity. In 1978, an ecological reserve was established to protect part of this area from increasing ...

Cakile maritima occurs sporadically along the southern Brazilian coast, where it is restricted to more protected sites at the base of foredunes. Somatic dimorphism in C. maritima is manifested as morphologically distinct ...

A field experiment was performed between February and May 2002 to evaluate the predation effects of migratory shorebirds on the macrofauna structure at an intertidal mudflat of the estuarine region of the Patos Lagoon. ...

This study aimed to predict the biological parameters (species composition, abundance, richness, diversity and evenness) of benthic assemblages in southern Brazil estuaries using models based on environmental data (sediment ...

La variabilidad temporal de la densidad de la macrofauna y su relación con las propiedades del agua y sedimento fue estudiada a través de muestreos mensuales en una ensenada estuarina de la Laguna de los Patos, Brasil, ...

Benthic macrofauna zonation was studied for one year (June 2004 to May 2005) with monthly sampling on Cassino Beach, Rio Grande do Sul, Brazil. Three sites (spaced 50 m apart) were selected. Three transects were anchored ...

An evaluation was made of the effects of dredging on the soft bottom community in the channel of the Rio Grande harbor in the Patos Lagoon estuarine region of southern Brazil. During four seasonal cruises, samples were ...

Turfeiras topotróficas caracterizam-se como corpos de águas rasas, permanente ou periodicamente alagados por água do lençol freático, percolada através do solo inorgânico das terras altas adjacentes à depressão central ...

Ao longo das margens do estuário da laguna dos Patos (no sul do Brasil), ocorrem 70 km2 de marismas irregularmente alagadas, sendo a grama Spartina densiflora Brong., uma das macrófitas emergentes dominantes. A variação ...

The main objective of this study was to evaluate the influence of vegetated beds on macrofauna community structure of the estuarine soft bottoms of the Patos Lagoon, southern Brazil. Comparative analyses were made by faunal ...

A warm core eddy was detected south of the Brazil–Malvinas (Falkland) Confluence (BMC) region in satellite images of the southwestern Atlantic Ocean in late 2002. The structure was also sampled by in situ instruments ...

The southern Brazilian shelf supports the largest fish stocks in the country, and studies on physical–biological processes in the ecology of ichthyoplankton have been recommended to provide a better understanding of the ...

The energetic analysis is an important diagnostic tool for the identification of dynamic processes associated with events of energy conversion in the ocean. In brief, that analysis shows the energetic interactions which are ...

We assessed the value of benthic macroinvertebrates to the diet of Farfantepenaeus paulensis juveniles in experimental pen-cages after three independent rearing periods of 20, 40 and 60 days each. For each time period we ...

The aim of this study is to compare the density and vertical distribution of ghost crab Ocypode quadrata burrows at three beaches with different degrees of anthropic impact. In order to achieve this, 12 1 m2 quadrants were ...

The movements are characterized by turbulent fluctuations in instantaneous speed, temperature and other scalars. As a consequence of these fluctuations, the turbulent state in fluid contributes significantly to transport ...

This study uses nine years of daily 9-km Pathfinder AVHRR/NOAA Sea Surface Temperature(SST) images to estimate the SST temporal variability of the southwestern Atlantic Ocean on time-scales ranging from sub-seasonal ...

Juvenile pink-shrimp Farfantepenaeus paulensis were exposed (75 days) to NH3 (0.016–0.287 mg L−1) under static condition with water renewal every 24 h. Experiments were performed at 20 °C, at a water salinity of 15 ppt, ...
