Method P.570 right column bottom paragraph: "Dinoflagellate cell volume was determined from linear measurements made with a Zeiss Axiovert microscope equipped with a digitizer pad and Microbiota software (Roff and Hopcroft 1986). Microscopic analysis of live cells was performed because fixatives can cause varying degrees of shrinkage (e.g., Verity et al. 1992, Leakey et al. 1994, Montagnes et al. 1994, Stoecker et al. 1994)."
Comments P.572 right column 2nd paragraph: "Volume measurements—All data presented here are based on size measurements performed on live cells. Average live-cell volume (µm^3) ranged from 180 to 2.79×10^5 µm^3, (Table 2). There was considerable variation in cell volume within species: the coefficient of variation (CV) averaged 33% (ranging 22–56%). This is comparable to other studies, which have reported volume measurement CV to be 25–30% and 49% (Putt and Stoecker 1989 and Verity et al. 1992, respectively). This size variability appears to be intrinsic to cultured protists and is probably due to differences in life cycle and growth status of individual cells, which even in clonal cultures are not necessarily synchronized."
