Although estuaries act as a sink of many pollutants, the assessment of microplastics pollution in these transition environments remain scarce or unknown. Sediments from estuarine intertidal areas possess a great ecological ...

The intertidal crabs Neohelice granulata and Cyrtograpsus angulatus are common on the south-west Atlantic coast but they rarely share the same microhabitat. They are similar in size and in several life history traits which ...

Temporal and spatial patterns of polychaete and oligochaete populations inhabiting intertidal sediments of the Quequén Grande estuary (Buenos Aires Province, Argentina) were analysed monthly during a yearly period. Local ...

Intertidal sediments of the inner and middle zonefrom the Bahı´a Blanca estuary were sampled for geochemicaland environmental assessment of metals (Cd, Cu,Pb, Zn, Mn, Ni, Cr and Fe). Results indicate that both theorganic ...

Organisms boring into intertidal consolidated sediments generate bioerosion. It is generally unknown, however, whether they can significantly contribute to coastline retraction. In this paper, we describe endolithic ...

Organic matter (OM) remineralization plays a key role in controlling the biogeochemistry of marine sediments. Through their burrowing activities, bioturbating macrofauna not only induces physical, chemical and biological ...

In coastal systems, benthic microalgae are important primary producers that significantly contribute to global primary production. Microphytobenthic (MPB) community structure and the ecosystem functions that it mediates ...

The aim of this work was to monitor levels of Cd, Cu, Pb, Zn and Fe in sediments, mussels (Mytilus edulis chilensis) and limpets (Nacella magellanica) from the Industrial zone (IZ); fuel dock (FD) and Ushuaia Peninsula ...

Chemical measures combined with biological data (biomarkers) are recommended in monitoring programs of marine environments. In the present research, the use of multiples biogeochemical indicators allowed interrelating ...
