INDICATION OF STREAM INTERMITTENCY USING MACROINVERTEBRATE COMMUNITIES ? SEARCHING FOR AN APPLICABLE APPROACH IN THE CZECH REPUBLIC

Popis výsledku v původním jazyce

Climate change has brought remarkable alterations in hydrological regime over the last decades and the lack of summer precipitation causes consequent periodical drying of 1st to 4th Strahler order streams. The extent of changes in macroinvertebrate community is related to various abiotic parameters (hydromorphology, available refugia, frequency of desiccation), as well as to biotic factors (competition, predation etc.). Regardless the specific conditions of each locality, the impact of drought is considered to be one of the crucial ecological filters leaving its footprint in the assemblage composition for a specific time corresponding with the extent of impairment. Based on these assumptions we are testing three approaches to bioindication of streams affected by annual or irregular drying. Firstly it is the usability of potential intermittency/permanency indicators selected using published data from intermittent streams.
