The aim of the present study isto characterise the diatom Pseudo-nitzschia community during a bloom period together with environmental conditions. High proliferation of Pseudo-nitzschia spp. was observed in September 2017 at the shellfish breeding area in the Krka River estuary (Central eastern Adriatic Sea). The peak of abundance (1.8 x 106 cells L-1) was recorded at 7 m depth, and the increased abundance persisted for four w...

In this study, we demonstrate that dissolved silica obtained from mineral (crystalline quartz), biogenic amorphous (diatomaceous earth) and artificial amorphous sources ( A erosil) influence the growth rate of two marine diatoms, C haetoceros sp. and S keletonema marinoi . Diatoms were reared in four different experimental conditions in artificial seawater containing either dissolved silica previously obtained through dissolut...
