Hydric recultivation—fooding of abandoned mining pits—creates a completely new, underexplored habitat for a wide range
of aquatic organisms. Periphyton and its response to abiotic factors were studied in the littoral zone of three post-mining lakes
with different ages of foundation situated in the Czech Republic. The studied habitat proved to harbour a huge periphytic diversity—25%
of diatom species found in the respective watershed (~5500 km2) inhabited exclusively the studied lakes. Species composition
of phototrophic microorganisms varied significantly among the studied lakes, seasons, and sampling years. However, the sampling depths and sampling site of the studied lake have not shown a significant impact on the diversity, indicating the homogeneous composition of the littoral periphyton within a particular lake and growing season. The seasonal dynamics of periphyton were unique for each lake, documenting three distinct successional patterns. The proportion of diatoms in the periphytic community decreases with the higher trophic state and flooding
age of the post-mining lakes. Cyanobacteria and mobile diatom forms prevailed later in the growing season, suggesting that
they could utilise nutrients released from the accumulated periphyton biomass.
