Lila Roldán, Cristina Guadayol, Òscar Estrada, Marta Cellular DNA content Dinoflagellates Net growth rate Orbital shaking Small-scale turbulence Swimming speed 13 pages, 6 figures, 3 tables Turbulence has been shown to alter different aspects of the physiology of some dinoflagellates. The response appears to be species-specific and dependent on the experimental design and setup used to generate small-scale turbulence. We examined the variability of the response of three dinoflagellate species to the turbulence, following the same experimental design used by Berdalet (1992) on Akashiwo sanguinea (Hirasaka) Ge. Hansen et Moestrup (=Gymnodinium nelsonii G. W. Martin). In all experiments, turbulence was generated by an orbital shaker at 100 rpm, which corresponded on bulk average, to dissipation rates (ε, quantified using an acoustic Doppler velocimeter) of ≈2 cm2·s−3. Turbulence did not appreciably affect Gymnodinium sp., a small dinoflagellate. However, Alexandrium minutum Halim and Prorocentrum triestinum J. Schiller exhibited a reduced net growth rate (33% and 28%, respectively) when shaken during the exponential growth phase. Compared to the still cultures, the shaken treatments of A. minutum and P. triestinum increased the mean cell volume (up to 1.4- and 2.5-fold, respectively) and the mean DNA content (up to 1.8- and 5.3-fold, respectively). Cultures affected by turbulence recovered their normal cell properties when returned to still conditions. The swimming speed of the cells exposed to agitation was half that of the unshaken ones. Overall, the response of A. minutum and P. triestinum was similar, but with lower intensity, to that observed previously on A. sanguinea. We found no clear trends related to taxonomy or morphology This work has been supported by the Spanish funded projects TURFI (REN2002-01591/MAR), VARITEC (CTM2004-04442-C02), and TURECOTOX (CTM2006-13884-C02-00/MAR), and by the EU project NTAP (EVK3-CT-2000-00022).
