Benthic diatoms are often used for assessing environmental conditions, such as water quality and habitat conditions in stream and river systems. Although laboratory experiments have shown that each diatom species have ...

We analyzed the diatom assemblages inhabiting the epipelic biofilm of a Pampean stream, characterized by their high basal nutrient levels, when exposed to a continuous surplus of inorganic nutrients. An in situ experience ...

A translocation experiment of epipelic biofilm was performed in order to explore the effects on this biological complex when exposed to different water qualities. To carry out such an experiment we employed artificial ...

The rivers and streams of the Pampean plain are subjected to the impact of agriculture, cattle-raising and industrialactivities. The largest urban center of Argentina is located here. The most important stresses ...

Chronic and pulse increments of salinity can cause different consequences on the aquatic communities, and its effects are related to factors such as the magnitude, frequency and ionic composition, as well as on the baseline ...

In this study we explored the use of less conventional diatom metrics (motility, nuclear abnormalities and ecological guilds) to measure changes in diatom assemblages related to the transfer of epipelic communities from ...

The structural features and O2 consumption of the epipelic biofilm in streams of the Pampean plain were explored. The study was conducted in three lowland streams subjected to different anthropic disturbances. Three sampling ...
