Diatoms are dominant group in a phytobenthos community of freshwater ecosystems. Their autecological features are well known, and various diatom indices are designed to estimate changes in aquatic ecosystems. In order to develop system for ecological status assessment in Montenegro according to the principles of the EU Water Framework Directive, quantitative and qualitative composition of benthic diatoms was studied. Phytobenthos sampling was carried out during July of 2018 at the Rivers Ćehotina, Lim, Tara, Zeta, Morača, Rijeka Crnojevića, Bojana, Komarnica, as well as at the Skadar Lake. Sampling, preparation of permanent slides, identification and enumeration of diatoms were done according to the standard methods. Altogether, 107 taxa belonging to 39 genera were recorded. The most diverse genera were found to be Navicula (12), Cymbella (11), Gomphonema (10) and Fragilaria (9). Achnanthidium minutissimum, Amphora pediculus, Cocconeis placentula var. euglypta, Encyonema minutum, E. ventricosum, Navicula cryptotenella and N. tripunctata were the most frequent, while taxa belonging to Achnanthidium sp., Cocconeis sp. and Encyonema sp. were the most abundant in the samples. Our research revealed dominance of β-mesosaprobic taxa, as well as taxa typical for mesotrophic to eutrophic conditions. It was also confirmed that IPS index is effective metric of stress in running waters. Presented data are in accordance with previous investigations of epilithic diatoms in freshwaters of Montenegro and comparable types of rivers in Serbia, and could be successfully used for further development of ecological status assessment in Montenegro.
