O Parque Nacional da Lagoa do Peixe (PNLP) possui uma grande variedade de ecossistemas que sustentam uma alta diversidade de espécies, sendo reconhecido internacionalmente por sua importância ecológica para as aves. No ...

In this paper we apply a Neural Network (NN) to reduce image dataset,distilling the massive datasets down to a new space of smaller dimension. Due to the possibility of these data have nonlinearities, traditional multivariate ...

This paper presents a description of marine atmospheric boundary layer (MABL) and oceanic boundary layer(OBL)interactions at the Brazil-Malvinas Confluence. Although this region is known as one of the most energetic ...

The OCCAM (Ocean Circulation and Climate Advanced Modeling Project ) is one of the global ocean circulation models which has been commonly used by the Brazilian oceanographic community. In most cases it is associated to ...

O objetivo deste estudo foi analisar a distribuição batimétrica e variação do número de espécies de macroinvertebrados bentônicos, na área de plataforma continental e talude superior no extremo sul do Brasil (32° 10´ - 33° ...

The spatial distribution of benthic macrofauna on the beaches of Tramandaí, Jardim do Éden and Harmonia, was investigated over five consecutive days in April, 2003. The distribution pattern was also analyzed along with ...

Aim To produce an inventory of south-west Atlantic saltmarshes (from latitude 31 48¢ S to 43 20¢ S) using remotely sensed images and field sampling; to quantify their total area; to describe the biogeographical variation ...

This study aimed to evaluate the e ects of the burrowing crab Chasmagnathus granulata on meiofauna at three intertidal habitats across a tidal exposure gradient (i.e., an emerged salt marsh, an emerged mudflat and a ...

Com base no estudo de 11 amostras de lama do fundo da laguna dos Patos, palinomorfos variáveis representados por poles e esporos de plantas terrestres e aquáticas vasculares, zigósporos, coenobium e colônias de clorofilas, ...

Os fitólitos produzidos pelas monocotiledôneas e preservados nos sedimentos quaternários, nas planícies costeiras, são ferramentas importantes nas reconstruções paleoambientais. Atualmente, a aplicação dos fitólitos em ...

1 Most studies of salt marsh plant zonation have been at middle to high latitudes of the northern hemisphere, in euhaline or periodically hypersaline marshes with regular tides. In this study, we examined plant zonation ...

The relative importance of carbon sources supporting aquatic food webs within and among estuaries may be influenced by factors that affect relative availability of autotrophic carbon sources, as well as movement of ...

The effect of seed mass on germination and growth was tested in fresh-seeds of Blutaparon portulacoides, Panicum racemosum, and Spartina ciliata, selected at random in southern Brazilian populations. The seed mass varied ...

O desenvolvimento e evolução das dunas costeiras dependem de diversos fatores, tais como, o suprimento de areia, cobertura vegetal e as espécies de plantas presentes. O objetivo deste estudo foi de examinar o efeito de ...

Light-stick is a light attractor used in longline fishing which is often dumped or lost into the ocean after used, becoming a potential pollutant to marine organisms. In the present study, toxicity was evaluated by exposing ...

Temporal variations of the macrofauna of sandy beaches have been related to variations in the beach morphodynamics and also to the population dynamics of dominant species. The aim of this article is to describe the temporal ...

Oceanic eddies are effective carriers of momentum, mass, heat, of chemical and biological characteristics associated generally with their place of origin. These features exercise influence on global circulation, in the ...

Long-term changes of water level in Mirim Lagoon, southern Brazil, are strongly associated with the El Niño-Southern Oscillation (ENSO). However, the relationship between the water lever recordand the Southern Oscillation ...

Copepods (Acartia tonsa) were exposed (48 h) to waterborne, diet-borne (non-Cu-equilibrated and Cu-equilibrated food), and waterborne plus diet-borne Cu in either the absence or the presence of food (diatom Thalassiosira ...

Hydrocotyle bonariensis é uma planta herbácea perene, rizomatosa com ampla distribuição ao longo da costa sudoeste Atlântica, crescendo típicamente em áreas expostas nas dunas e em locais onde o lençol freático está próximo ...
