TI  - The phytoplankton functional group concept provides a reliable basis for ecological status estimation in the Çaygören Reservoir (Turkey)
AB  - The phytoplankton functional group (FG) concept has been successfully used to determine water quality states in both lakeand river systems, but is not yet stressed in regular studies in reservoir environments. The purpose of our study was to estimate theecological status of the temperate Çaygören Reservoir (2007 2009) using the Q(r) FG composition metric, and to test whether it is ableto follow the main structuring of the physical and chemical parameters studied. The main occurring coda were codon C (Cyclotellameneghiniana Kützing, Stephanodiscus neoastraea Hakansson and Hickel), codon T (Gloeotila subconstricta (G.S. West) Printz,Mougeotia sp.), codon X2 (Cryptomonas py renoidif era Geitler, Plagioselmis nannoplanctica (H.Skuja) G.Novarino, I.A.N.Lucas andS.Morrall), codon K (Aphanocapsa holsatica (Lemmermann) G.Cronberg and J.Komárek, Aphanothece clathrata West and G.S.West),and codon S1 (Planktothrix sp.). The seasonal succession of phytoplankton displayed the lake-like coda series of Y (winter) → C (spring)→ K/S1 (summer) → T (fall) in each year, which demonstrated well the transitional behavior of reservoirs between lake and riverecosystems. The FG compositions showed high relationships with water temperature, ammonia, phosphate, and light availability inthis temperate reservoir, where the Q(r) index estimated reliable water quality states between hypertrophic and oligotrophic conditions.
