for bloom and non-bloom sites, respectively, in 2010 (Fig. 3A) with the
highest densities observed on 3 August 2010. Flow cytometric analyses
revealed significantly (four-fold) higher autotrophic picoeukaryotic
densities inside the bloom patches compared to outside
(18.8 4.84 105 and 4.35 0.64 105 cells mL1, respectively;
p < 0.001; Fig. 3B) while cyanobacterial densities were significantly
lower (by half) in bloom water (3.11 0.63 105 and
5.72 1.16 105 cells mL1, respectively; p < 0.05; Fig. 3C).
