The biological assessment of rivers ie, their assessment through use of aquatic
assemblages, integrates the effects of multiple-stressors on these systems over time and is …

Human-driven global change is causing ongoing declines in biodiversity worldwide. In order
to address these declines, decision-makers need accurate assessments of the status of and …

Rivers suffer from multiple stressors acting simultaneously on their biota, but the
consequences are poorly quantified at the global scale. We evaluated the biological …

Macroinvertebrate metrics are helpful tools for the assessment of water quality and overall
aquatic ecosystem health. However, their degree of sensitivity and the most reliable metrics …

Water quality agencies and scientists are increasingly adopting standardized sampling
methodologies because of the challenges associated with interpreting data derived from …

The aim of this study is to generate a first global overview of pressures and methods used to
assess the environmental quality of rivers and streams using macroinvertebrates. In total …

Monitoring programs at sub-national and national scales lack coordination, harmonization,
and systematic review and analysis at continental and global scales, and thus fail to …

Increased fine sediment deposition and entrainment in rivers can arise from a combination
of factors including low flows, habitat modification and excessive sediment delivery from the …

Anthropogenic activities, including combustion of fossil fuels, coal, and gold mining, are
significant sources of mercury (Hg) emissions into aquatic ecosystems. South Africa is a …

Tolerance values (TVs) based on benthic macroinvertebrates are one of the most widely
used tools for monitoring the biological impacts of water pollution, particularly in streams and …
