eng Abstract:
Two outflows from atmospherically-acidified Čertovo and Laka lakes in the Bohemian Forest in the Czech Republic were surveyed in 2005 and 2007. Water chemistry and macrozoobenthic community composition in longitudinal gradient of both streams were analyzed to determine the present status of the streams. Streams' chemistry reflects the current situation of both lakes. The progress in chemical reversal to natural conditions was observed in longitudinal gradients of both streams (greatly induced by chemically-inert tributaries). Macrozoobenthic recovery was evident only in Laka Lake´s outlow, mainly by increasing Ephemeroptera and Trichoptera taxonomy richness in longitudinal gradient. In Čertovo Lake´s outflow, there were no considerable changes in benthic community composition, because chemistry in the whole locality of Čertovo Lake was limiting for acidosensitive taxons.
