Diatoms in water quality assessment: to count or not to count them?

Popis výsledku v původním jazyce

Two methods of quantifying diatoms for the purposes of ecological evaluation of rivers were compared: (i) by counting valves, and (ii) by simple assignment of individual species to a sevenpoint scale according to their coverage on a glass slide. Saprobity-trophic indices based on coverage classes achieved higher correlation with the fundamental water chemistry parameters than did indices based on diatom valve counts.The results support the assumption that the main cause of the poorer predictive value for the index based on diatom valve counts is that the abundant taxa are attributed too much importance in the final assessment of the environment quality. Using degrees of coverage for the quantification of diatoms in evaluating the ecological status thus appears to be preferable (or at least sufficient) for the ecological assessment of rivers.
