Skeletonema grevillei, a regular and bloom forming diatom in the coastal waters of the adriatic sea
Skeletonema grevillei Sarno et Zingone was described in 2005. from the original type material. Cells were delicate, 4–7.5 μm in diameter, and formed short colonies. The fultoportulae processes in the terminal valves were open tubes having narrow tips with truncated or spiny margins. In the intercalary valves, they formed knuckle-like generally 1:1 junctions. A scallop-work of silica bridges joined the bases of the processes. Type locality for this species is Hong Kong bay, and several other authors report this species in Japan, Australia and Muscat Oman. Skeletonema grevillei Sarno and Zingone was observed for the first time in the Adriatic Sea in 2014 during the autumn bloom when it reached high abundances (5.4 x 106 cells / L). The bloom started in september with the peak in november/december and lasted until january/february. The highest abundances were found in the surface layer from 0-10 m depth. We observed colonies from 3-26 cells in both cultures and natural samples. The valve face was slightly convex, and the pervalvar axis is generally longer than or as long as the cell diameter. The cell diameter was from 5-19 μm. The IFPPs are rather long (8.5 ± 1.6 μm n=13), each joining one IFPP of the adjacent cells (1:1 junction), with a thickening at the joint. We here report in situ observations for S. grevillei with additional information on their morphological and genetic characteristics as well as ecology.
