| Description | Natural drying up of streams is not common in Middle Europe. Nevertheless, the recurrent drying up of small streams in last decades has shown an urgent need to pay attention to the impact of global climate change. Drying up is a strong disturbance that influences conditions in streams markedly and causes changes in the taxonomical and functional structure of biota. The aim of the study was to compare macroinvertebrate assemblages of one intermittent and one permanent brook. The study was carried out in two stretches with otherwise comparable environmental parameters. Lower densities of macroinvertebrates were found at the intermittent site but the difference was not significant. The number of taxa and diversity were significantly higher at the permanent site. Functional structure of the assemblages also varied. The shares of rheobionts, grazers and predators differed. The research was supported by project TA02020395. |
