The effect of drying up on macroinvertebrate communities in small streams of Central Europe

Popis výsledku v původním jazyce

Climate change has brought remarkable changes in hydrological regime over the last decades and lack of summer precipitation causes consequent periodical drying out of small streams also in Central Europe. Insufficient data from this region lead us to conduct the studies of intermittent stream in the Czech Republic, which were focused on drought-related ecological filters affecting aquatic macroinvertebrate communities. The extent of community impairment is related to abiotic parameters (e.g. refugia availability, water quality, frequency and regularity of desiccation etc.), as well as to biotic factors, namely individual ?species traits? (recolonization capacity, aestivation, drought-resistant stages etc.). Duration and extent of drought determine therange of changes in key assemblages (e.g. EPT taxa), and the degree of dissimilarity comparing to permanent stream assemblages can indicate the extent of dry period in the history of a watercourse. Different approaches focused e.g.
