Freshwaters face multiple environmental problems including eutrophication, acidification,
salinization, and climate-change, all of which can lead to impairment of ecosystem structure …

The objective of this review is to highlight the importance of the use and application of
bioindicators in the evaluation of the quality of water bodies from their origins to the present …

As freshwater algae respond strongly to environmental conditions, algal communities are
routinely used as indicators of aquatic health. Algal bioassessments have historically relied …

Predictive biological indices have transformed the bioassessment landscape by allowing
universal indices to be applicable across diverse environments. The successful …

The effects of urban growth are multidimensional and therefore they cannot be assessed
using only one indicator. The objective of this study was to assess the environmental quality …

Biological assemblages in streams are influenced by hydrological dynamics, particularly in
non‐perennial systems. Although there has been increasing attention on how drying …

Legal frameworks that assess stream ecological integrity rely mostly on structural metrics
and implicitly assume that good structure will result in good function. This assumption may …

Background Stream ecosystems comprise complex interactions among biological
communities and their physicochemical surroundings, contributing to their overall ecological …

A key challenge in managing flow alteration is determining the severity and pattern of
alteration associated with the degradation of biological communities. Understanding these …

This work aims to evaluate the effects of different environmental factors (ie, geographical,
chemical, and hydrological) on benthic diatoms at 34 sites located in 13 watercourses of …
