Název v původním jazyce

The ecological effect of drought on the macroinvertebrate fauna of a small intermittent stram - an example from the Czech Republic

Popis výsledku v původním jazyce

The impact of an unstable hydrological regime on macroinvertebrates in an intermittent stream (Gránický brook, Czech Republic) was investigated in two successive years with differing climatic conditions. The brook has a specific character with periodic summer droughts in particular stretches. Ten series of macroinvertebrate samples were taken from two sampling sites between April 2002 and October 2003. Total abundance, taxa richness, main faunal groups and life strategies were assessed in order to describe the changes in the macroinvertebrate assemblages. Periodic dry periods caused a decrease in macroinvertebrate density in the intermittent stretch, whereas they had no negative influence on number of taxa. Before the drought, the density of permanentfauna decreased and the number of r-strategists rose and stayed at a high level in after-drought period.
