Název v původním jazyce

Benthic rotifers and flow velocity in two low-order streams.

Popis výsledku v původním jazyce

The primary objective of this study was to determine the relationship between moss-dwelling and the surrounding mineral substrata-dwelling rotifers with local flow velocity in two low-order streams. Differences in rotifer distribution between riffle andpool areas of the studied streams (the Bystřice, Czech Republic and the Oberer Seebach, Austria) were also assessed. Bdelloid rotifers showed a positive or no significant relationship with local flow velocity within Fontinalis antipyretica and no clear relationship was observed within the mineral bed. However, monogonont rotifers were related to local flow velocity negatively or no significance was found within moss. Our data on the distribution of moss-dwelling monogononts in riffles and pools indicatethat monogonont rotifers avoid the erosive impact of higher flow velocity in low-flow areas (pools). No clear relationship was observed within the mineral bed, as in bdelloids. The introduced B/M ratio (i.e., Bdelloidea : Monogononta abu
