- Abstract
Seasonal impact on the ecological status assessment through macrozoobenthos in representative lentic water bodies (lakes and dams) situated at Ecoregion 7 Eastern Balkans (South Bulgaria) was made. Data from twelve standing water bodies during three seasons (summer 2018, autumn 2018 and spring 2019) were analysed. The Total number of taxa index showed seasonal dependence. The Biotic index was not significantly changed across seasons in different types of stagnant waters. The seasonal effects on the ecological status/potential evaluation depended on the type of the standing water body (natural/heavily modified/artificial), environmental factors and different anthropogenic pressure which caused changes in the aquatic ecosystems.
