Using Aquatic Macroinvertebrates as Indicators of Streamflow Duration

Using Aquatic Macroinvertebrates as Indicators of Stream Flow Duration

Food, substrate or both? Decomposition of reed leaves (Phragmites australis) by aquatic macroinvertebrates in a large shallow lake (Lake Balaton, Hungary)

The aim of this study was to investigate the use and decomposition of reed leaves (Phragmites australis) by aquatic macroinvertebrates in a lake environment (Lake Balaton, Hungary). Natural and artificial leaves were exposed to separate the use of leaves as substrate and as food at different vertical positions. Although we recorded a low density of macroinvertebrates, mixed-effect models showed...

River health assessment using macroinvertebrates and water quality parameters: A case of the Shanbeh-Bazar River, Anzali Wetland, Iran

The study of benthic macroinvertebrate communities is one of the most common methods for assessing the effects of stresses on the biological conditions of aquatic ecosystems and water quality monitoring. This research was conducted to study the changes in the macroinvertebrate communities in the Shanbeh-Bazar River, Anzali International wetland and the effects of environmental factors. Sampling...

Evaluation of geographic, geomorphic and human influences on Great Lakes wetland indicators: A multi-assemblage approach

Developing effective indicators of ecological condition requires calibration to determine the geographic range and ecosystem type appropriate for each indicator. Here, we demonstrate an approach for evaluating the relative influence of geography, geomorphology and human disturbance on patterns of variation in biotic indicators derived from multiple assemblages for ecosystems that span broad spa...

Metal contamination in benthic macroinvertebrates in a sub-basin in the southeast of Brazil.

Benthic macroinvertebrates have many useful properties that make possible the use of these organisms as sentinel in biomonitoring programmes in freshwater. Combined with the characteristics of the water and sediment, benthic macroinvertebrates are potential indicators of environmental quality. Thus, the spatial occurrence of potentially toxic metals (Al, Zn, Cr, Co, Cu, Fe, Mn and Ni) in the wa...
