Streams of the pampas region (central Argentina) are characterized by the lack of riparian
forests and by low current velocities, and receive a large amount of industrial and domestic …

The rivers and streams in the pampean plains are characterized by a low flow rate due to the
low slope of the surrounding terrain, high levels of suspended solids, silty sediment in the …

Benthic diatom investigations of some Hungarian streams have been carried out in order to
find reference sites in assistance to the ecological quality analysis of the different river types …

Lowland lotic ecosystems are under increasing pollution pressure. In this study, we
analyzed the plankton community responses to environmental changes, including natural …

Headwater streams play an essential role in catchment ecosystem processes and are
particularly vulnerable to land use degradation and anthropic hydrological alterations …

Our objective was to assess the effect of the physical habitat degradation in three lowland
streams of Argentina that are subject to different land uses. To address this matter, we …

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 …

Diatoms are useful ecological indicators because they are found in abundance in most lotic
ecosystems. The use of diatoms as indicators of the quality of river waters is widely accepted …

Microalgae communities have been used for monitoring continental freshwaters in South
America, mainly in Argentina and Brazil. Considering that the epipelic diatom community …

Benthic diatoms are often used for assessing environmental conditions, such as water
