Stream habitat or water quality - what influences stronger fish and macrozoobenthos biodiversity?

Popis výsledku v původním jazyce

The data obtained within the framework of a survey of macrozoobenthos and fish communities in Czech streams of the Danube and Elbe river basins were evaluated with respect to the relation between biodiversity and level of water (organic pollution) and/orphysical habitat quality (heterogeneity, substrate, riparian vegetation, canalisation). The diversity of macrozoobenthos species was highest in water quality corresponding to betamesosaprobity (saprobiological index SI ? 2,0) and oligosaprobity (SI ? 1,0) in lowland and highland streams respectively, declining both towards lower and higher saprobic (? trophic) levels. The response of macrozoobenthos to habitat quality deterioration was less considerable with rising degradation in highland streams thanin lowland. Fish assemblage followed a similar trend with the highest biodiversity in betamezosaprobity in both lowland and highland streams. In comparison with the assemblage of benthic macroinvertebrates, fish community response was mor
