| Abstrakt: | Abstract: The contribution provides the information about the fauna of water mites in 14 localities of small watercourses in the Bohemian-Moravian Highlands that were sampled in 1964 and 2018. The exactly same methodology was applied to the samples and their processing in the same localities in both compared years. The main objective was to assess how the fauna of water mites have changed and if the occurrence of water mites can be used for the assessment of changes in water ecosystem conditions. The results showed that the abundance of water mites found in 2018 represented 47% of the numbers found in 1964. The number of the species found also decreased moderately from 33 to 28 in 2018. The changes in composition and frequency of occurrence of the water mite species found in both examined years are compared in detail. The results confirm that the fauna of water mites can be the important comprehensive indicator of biocoenosis changes in the ecosystems of small watercourses. |
