Nas últimas décadas comunidades de tapetes microbianos têm sido descritas nos mais diversos ambientes do hemisfério Norte, enquanto que a escassez de relatos para a América do Sul reflete a falta de estudos e grupos dedicados ...

Forecast of biological consequences of climate changes depend on both long-term observations and the establishment of carbon budgets within pelagic ecosystems, including the assessment of biomasses and activities of all ...

Seasonal and inter-annual patterns of hydrological variation determine different salinity regimes inside the Patos Lagoon estuarine region, southern Brazil. Throughout two environmentally distinct years (2000 and 2006), ...

The southern area of the Patos Lagoon estuary has been subjected to intense industrial and port-related activities which have not only caused meaningful changes in the landscape but also degraded aquatic resources by ...

This study was undertaken to evaluate temporal trends of litter contamination at Cassino beach, Southern Brazil. Surveys were conducted between 1994 and 1995, and then resumed from 2003 to 2006. Litter composition was ...

The temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil, was studied for a period of one year (June 2004 to May 2005) based on monthly sampling. Three sites were selected distant 50m from each ...

Water quality, phytoplankton and zooplankton were evaluated in a shrimp pond (Litopenaeus vannamei) and the adjacent Patos Lagoon estuary in summer from November/2007 to February/2008. Every two weeks, temperature, salinity, ...

The aim of this work was to study the relationships between temporal variability of Erodona mactroides and abiotic parameters of the water column and the substrate in a shallow embayment of the Patos Lagoon estuarine ...

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, ...

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 ...

Grande parte da população mundial vive em zonas costeiras, o crescimento urbano quando desordenado, acarreta em prejuízos tanto econômicos quanto ambientais para esses locais. As variações no clima também possuem importante ...

Atualmente, a Terra passa por mudanças climáticas que são responsáveis pelo aumento de temperatura atmosférica e oceânica. O hemisfério sul do planeta concentra a maior parte das alterações percebidas no oceano e cerca de ...

This study uses a Geographical Information System (GIS) for terrain analysis of the Keller Peninsula (KP), King George Island (KGI), Antarctica, to describe its morphological characteristics. We processed a vertical metric ...

This paper presents a technique to evaluate the environmental vulnerability of a portion the Rio Grande do Sul Coastal Plain, Brazil, by using the Geographical Information System IDRISI 32. After defining environmental ...

Nos cultivos intensivos de organismos aquáticos, o acúmulo de compostos nitrogenados pode ocasionar efeitos negativos, afetando o crescimento e a sobrevivência dos animais. Nos sistemas BFT (Biofloc Technology System) os ...

Pseudis minuta is abundant in a variety of aquatic environments of the Pampa domain. Therefore, it can be considered a good model for testing hypotheses on environmental heterogeneity and the influence of climate on the ...

The aim of this study was to evaluate the anesthesia induction and recovery times of sub-adult and postlarvae white shrimp (Litopenaeus vannamei) that were treated with eugenol and the essential oils (EOs) from Lippia alba ...

Predation on Illex argentinus (Cephalopoda, Ommastrephidae) in southern Brazil (26°S to 34°S) was studied from its presence in contents of over 14 000 stomachs from 63 potential predator species including fishes, cephalopods, ...

Abstract The single, long and narrow channel that usually connects choked coastal lagoons to the ocean can serve as a natural hydraulic low-pass filter that reduces or eliminates tidal and subtidal effects inside the lagoon. ...

An agreement between the Executive Group for Industrial Fisheries Development (GEDIP) and the Oceanographic Institute of the University of São Paulo (IOUSP), gave rise to an extensive project. This extensive project was ...
