Anotace
V originále
The ongoing climate change results in more frequent hydrological extremes. Complete or partial drying of small water courses had become a relatively common phenomenon in the Czech Republic and the need for a tool for assessing the drought impacts on aquatic environment emerged. A novel method for bioindication of dry episodes in Czech streams and small rivers (up to 4th order according to Strahler) was one of the main outcomes of the past project BIODROUGHT (www.biodrought.eu). It is a retrospective method indicating dry episodes which occurred during the previous vegetative season, and it is based on the analysis of taxonomic and functional composition of benthic macroinvertebrate communities (BIODROUGHT index). This poster presents: i) an approach to the discrimination of invertebrate communities influenced by different levels of drought impact (i.e. no impact, slight impact and marked impact), ii) a success rate of drought indication using independent samples taken by routine monitoring, and iii) the available tools for calculating BIODROUGHT multimetric index. The project was supported by the Technology Agency of the Czech Republic (No. TA02020395).
