The study is focused on diatom communities as indicators of the water
quality of aquatic ecosystems. The study included watercourses of the Timok
River Basin in eastern Serbia. Sampling of algological material and physicochemical
measurements were conducted at 30 locations in September 2016.
Non-metric multidimensional scaling (NMDS) showed that conductivity had
an effect on the spatial variability of the diatom communities. At locations under
influence of acid mine drainage along the Borska river, its tributaries and
the Timok river, the diversity of benthic diatoms decreased and the abundance
of metal tolerant taxa Achnanthidium minutissimum, Nitzschia capitellata and
Nitzschia palea increased. Our study revealed that the combined effect of different
pollutants significantly impacted on diatom assemblages; diatoms are good
bioindicators of multiple pressures; and diatom indices with different types of
pollution, may show an unreliable picture of the actual state, therefor...e, biological
and physico-chemical parameters should also be observed when interpreting
the results of a solely diatom-based assessment of the ecological condition of
freshwaters.
