Based on macrophytes, it was possible to divide the Hron River into two sections. The upper section is relatively poor in species (species number – 3) when comparing it to the lower section (3.5). We suspect that, regarding the dominant influence of food availability, there only exists a very uncertain preference of visiting sections with a higher qualitative and quantitative representation of macrophytes in the watercourse. We found that in the lower section, that had a higher number of macrophytes, there were higher amounts of otter signs. The Hron River otter therefore seems to slightly prefer sections, which have greater macrophyte richness. However, differences in amount of otter signs between mentioned sections are relatively small and with statistically no significance URL Link na zdrojový dokument Public work category ADE No. of Archival Copy 18056 Repercussion category JUHÁSZ, Krisztina - LUKÁCS, Balázs A. - PERPÉK, Mónika - NAGY, Sándor Alex - VÉGVÁRI, Zsolt.
