benthic macroinvertebrates in river are useful indicators for adverse impacts on the catchment and river ecosystems. these organisms integrate many ecological processes in catchment scale. in this study several single and multi metric biotic indices were used based on macroinvertebrates in order to evaluate the water quality of jajrood river. macroinvertebrates as well as water samples were col...

some macroinvertebrate indices of stream health have been identified as most useful and efficacious. management decisions can be made with greater awareness.the objectives of this study were to assess the biological water of the hazar river using macroinvertebrates.the haraz river is one of the best freshwater ecosystems in the mazandaran province located in the north of iran.to assess the macr...

The influence of environmental factors on biotic responses to nutrients was examined in three diverse agricultural regions of the United States. Seventy wadeable sites were selected along an agricultural land use gradient while minimizing natural variation within each region. Nutrients, habitat, algae, macroinvertebrates, and macrophyte cover were sampled during a single summer low-flow period ...

The need to assess the environmental status of marine and coastal waters according to the EU Water Framework Directive (WFD) encouraged the design of specific biotic indices to evaluate the response of benthic communities to human-induced changes in water quality. In the present study three of these indices, the traditional Shannon Wiener Index (H') and the more recently published AMBI (AZTI' M...

 Benthic invertebrates are a well-established target in environmental quality status evaluations. The AMBI (AZTI's Marine Biotic Index) was developed to determine the impacts and the quality status of soft-bottom marine benthic communities. The aim of this study was investigating multivariate pattern of benthic invertebrate community and application of AMBI (AZTI's Marine Biotic Index) for...
