Elevated nutrients and sediments are the main factors contributing to the poor biological
condition measured in over 40% of US waters, highlighting the need for criteria that can aid …

Recent studies have demonstrated that there is generally no unambiguous relationship
between plant species composition and specific environmental conditions in rivers …

Environmental biomonitoring techniques have been widely applied to assess the quality
states of toxic chemical compounds in surface freshwater quality. The methods based on …

Monitoring programmes worldwide use biota to assess the “health” of water bodies. Indices
based on biota are used to describe the change in status of sites over time, to identify …

The spatial organisation of biotic communities derives from factors operating at a wide range
of spatial and temporal scales. Despite strong scientific evidence of prevalent spatial control …

There is a long tradition of river monitoring using taxonomy-based metrics to assess
environmental quality in Europe via benthic macroinvertebrate communities. A promising …

Although many studies have focussed on the effects of catchment land use on lotic systems,
the importance of broad (catchment) and fine (segment/reach) scale effects on stream …

Este artículo presenta una revisión acerca del uso de bioindicadores para la evaluación de
la calidad del agua en ríos. El objetivo es presentar investigaciones relacionadas con el …

Benthic algae are widely used as ecological indicators of the ecological status of streams
because they are widely distributed, they show high species diversity and they respond …

We present the process of developing a macrophyte based index (River Macrophyte Index–
RMI) for assessing river ecological status, that would be applicable for rivers with moderate …
