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 …

Freshwater biota are more comprehensive and direct indicators of biological impacts, and
more meaningful to the public than water quality or physical habitat surrogates. Freshwater …

Generally, habitat loss and fragmentation negatively affect biota, often in nonlinear ways.
Such nonlinear responses suggest the existence of critical limits for habitat loss beyond …

Urban pollution is increasing at an alarming rate within the catchments of forested riverine
systems in sub-Saharan Africa, Nigeria inclusive. Assessing the impact of pollution in …

Accurate and precise detection of anthropogenic impacts on stream ecosystems using
macroinvertebrates as biological indicators depends on the use of appropriate field and …

Abstract Most Latin American demands for drinking water are in or near urban areas.
However, population growth and untreated sewage disposal degrade water quality, with …

Urban pollution of riverine ecosystem is a serious concern in the Niger Delta region of
Nigeria. No biomonitoring tool exists for the routine monitoring of effects of urban pollution …

The effects of anthropogenic disturbance on multiple facets of biodiversity are poorly
understood. In this study, we worked with the hypothesis that anthropogenic disturbances …

Agricultural activities often lead to nutrient enrichment and habitat modification in rivers,
possibly altering macroinvertebrate assemblages and hence ecosystem functioning. For the …

Biological assessment is an important component of river health assessments. With the
thorough growth of river health assessment in China, the scientific verification and screening …
