ABSTRACT To determine the presence of emergent contaminants in aquatic environments and to evaluate responses dominant taxa benthic macrofauna, seven stations were sampled along three rivers that serve as public water suppliers sampling campaigns, Upper Iguassu Basin, Brazil. Concentrations ethinylestradiol, fenofibrate, ibuprofen triclosan detected sediment. correlate patterns distribution abu...

An appropriate approach to assess the effect of toxicants on aquatic animals is to monitor behavioral endpoints, as they are a link between physiological and ecological processes. A group that can be exposed long-term to low toxic concentrations is benthic macroinvertebrates, as their mobility in aquatic ecosystems is relatively limited. Therefore, the study of behavioral long-term effects in t...

The study was conducted in Karasu Stream (Sinop Province, Black Sea Region of Turkey). purpose this is, to determine the benthic macroinvertebrate composition stream, together with some its environmental characteristics (water temperature, pH and dissolved oxygen) evaluate trophic level stream. Samplings macroinvertebrates variables were performed monthly at ten stations between February 2013 J...

Benthic macroinvertebrates are among the most used biological quality elements for assessing condition of all types aquatic ecosystems worldwide (i.e., fresh water, transitional, and marine). Current morphology-based assessments have several limitations that may be circumvented by using DNA-based approaches. Here, we present a comprehensive review 90 publications on use DNA metabarcoding benthi...

Regional data needed for effective stream restoration include hydraulic geometry relationships (i.e., regional curves) and reference channel morphology parameters. Increasingly ecological conditions are being considered when designing, implementing, and assessing restoration efforts. We provide morphology relationships and associated ecological endpoint curves for reference streams in the Alaba...
