| Popis | In the river Nedvědička, a unique situation was found in the place where heated decontamination mining tributary (size 1m wide, from power plant) flows into the river. We sampled quantitatively a macrozoobenthos and algae once a month over the course of the year. We also monitored temperatures (by thermometer) in four sampling places every 15 minutes from November 2007 until today. The results of the analyses of RDA, which include measuring parameters, show temperature significant (p-value 0,033). High conductivity is caused by great amount of sulphates, and therefore, we took conductivity like covariate. The specificity of the tributary is that we can find various species that cannot be found in the river Nedvedicka. Thermal tributary increases the water temperature under the tributary, and significantly changes species assemblages and their abundances. Financial support for this study was provided by the Funding of Ministry of Education of Czech Republic project No. MSM0021622416. |
