ASSESSMENT OF THE ECOLOGICAL STATE OF RIVERS BASED ON BENTHIC ALGAE, ESPECIALLY DIATOMS. Autori: LAURA MOMEU, LEONTIN ŞTEFAN PÉTERFI. |

Rezumat: The present paper presents the main aspects concerning monitoring programs of running waters for assessing their ecological status. It is very important to know the characteristics of lotic ecosystems, the role of algae as primary producers, as well as the legal framework ruling monitoring programs. Since the representative algal community for running waters in the upper, middle and sometimes lower reaches is the benthic one (periphyton), the paper depicts the importance of choosing the proper type of substratum and algal sampling, together with the correct manner of sample handling. In concordance with the literature but also with personal data, the present paper shows the importance of using biotic indices in assessing the ecological status of running waters. Keywords: running waters, benthic diatoms, biotic indices, modern concepts, truncated normal curve |
