Acute semistatic toxicity tests were carried out for 96 h with first zoeae and young crabs of Chasmagnathus granulata. Survival curves and LC50 (lethal concentration 50, the concentration which produces the death of 50% ...

The Bahía Blanca Estuary is a complex system of channels and tidal flats where the most important deep water harbour system of Argentina is located. The main goal of the present work was to obtain a hydrodynamic conce...

Field measurements of the Malvinas Current (MC) velocity distribution were performed at the western slope of the Argentine Basin in the South Atlantic Ocean between 47° and 43°S including several sections across the cu...

Beach-ridge systems are a common feature of prograding coastlines and they have been recognized as important archives of late Quaternary sea level. In this paper, the combination of Landsat images and shuttle radar topog...

In semi-arid environments there is often a lack of data on hydrological variables that limits the ability to understand key hydrological processes. In response to this need, geomorphometric analysis is a quantitative app...

Coastal regions are sectors where human activities impact the marine ecosystem, and if necessary control measures are not taken, they can generate negative consequences for health and ecosystem services. Within the frame...

Tidal flats generally exhibit ponds of diverse size, shape, orientation and origin. Studying the genesis, evolution, stability and erosive mechanisms of these geographic features is critical to understand the dynamics of...

This study investigates the ingestion of microplastics (MPs) by zooplankton in the surf zone of southwestern Atlantic sandy beaches, an extremely turbulent environment with high interaction between suspended particles. S...

This study address for the first time in Argentina and the South American continent the effect of water management on the presence of microplastics (MPs) in a shallow lake, assessing their contribution to the zooplankton...

The preservation and cementation of sedimentary structures under the influence of  microorganisms in siliciclastic environments have been poorly studied in contrast to carbonatic settings, where they have been extensive...

Fractures are common in the Earth  crust due to different factors, for instance, tectonic stresses and natural or artificial hydraulic fracturing caused by a pressurized fluid. A dense set of fractures  behaves as an e...

RESUMO O ensino de Ciências foi incorporado aos currículos escolares somente no século XIX. No Brasil-Império o ensino das Ciências Naturais era incipiente, embora ciências já fizessem parte do currículo do ensin...

Phytochelatins (PCs) and monothiols and their relation with trace element concentrations were studied in three plant species from two Portuguese salt marshes. Belowground tissues showed always higher element concentratio...

The presence of evidence of depredation in ostracods valves from marine and freshwater environments of the central region of the republic Argentina are studied in this paper. In samples from intertidal environment (Puert...

Microbially-colonized sediments tend to be more resistant to erosional events than mostly abiotic sediments. However, the effect of complex microbial associations, such as microbial mats over sediments and the protection...

Seasonal variations in diversity and biomass of tintinnids (Ciliophora: Tintinnida) were investi- gated at two fixed stations in the inner part of the Bahía Blanca Estuary (38°42` S, 61° 50` W) during an annual cycle....

Total heavy metal concentrations have been monitored for almost thirty years, while organotin compounds have only been evaluated in the last few years. Intertidal as well as subtidal surface sediments were fully analyzed...

The global demand for materials and energy grows apace since the middleof last century and no stopping seems feasible in the next decades. Despiteincreasingly strict controls of emissions from anthropogenic sources, thed...

Marine microbial plankton hold high structuraland functional diversity, however, high-resolution data are lacking in a largepart of the Global Ocean. The Burdwood Bank (BB) hosts rich benthicbiodiversity in low chlorophy...
