Bioindication has become an indispensable part of water quality monitoring in most
countries of the world, with the presence and abundance of bioindicator taxa, mostly …

Algae have been used for a century in environmental assessments of water bodies and are
now used in countries around the world. This review synthesizes recent advances in the …

Assessments of environmental conditions in rivers and streams with diatoms have a long
history, which has resulted in the development of the two basic conceptual and analytical …

Diatoms are excellent ecological indicators of water quality because they are broadly
distributed, they show high species diversity and they respond rapidly to human pressures …

Two major arguments in favor of using diatoms in water-quality assessments are that their
distributions are cosmopolitan and their ecology is well studied. If these assumptions are …

Diatoms have been widely used to detect changes in streams and rivers water quality due to
their specific sensibility to a variety of ecological conditions. Their tolerances and …

Littoral diatoms are important contributors of the primary production in shallow aquatic
ecosystems and they can be used as indicators of the trophic status. The aim of the study …

Nutrient pollution remains one of the leading causes of river degradation, making it
important to set thresholds that support good ecological condition, which is the main …

The inclusion of diatoms into the current suite of biomonitoring tools in use in South Africa,
as well as the use of European and other diatom indices in South Africa, and in particular the …

Freshwater diatoms are considered to be reliable indicators of the trophic status of rivers and
lakes. In the past 30 years, a number of indicator indices have been developed and used for …
