Figures & data
TABLE 1 Results of two-way ANOVAs for Chloromonas rosae v. psychrophila (A) and two studies of Chloromonas tughillensis (B and C) with cell count as the dependent variable and strain and growth temperature as fixed factors.
FIGURE 1 Mean cell counts (+1 SE) of growth after four weeks for different strains of Cr. rosae v. psychrophila (A), Cr. tughillensis (B and C), and Cr. chenangoensis (D) at different temperatures (°C).
FIGURE 2 Mean cell counts (+1 SE) of growth after four weeks for Cr. rosae v. psychrophila strain CU 204 (A) and strain CU 479A (B) at different temperatures (°C). Closed bars denote cultures that were acclimated at each temperature; open bars denote cultures that were not acclimated.
TABLE 2 Results of two-way ANOVAs for Chloromonas tughillensis strains with cell count as the dependent variable and growth temperature and acclimation temperature as fixed factors.
FIGURE 3 Mean cell counts (+1 SE) of growth after four weeks for different strains of Cr. tughillensis under combinations of growth (first temperature) and acclimation (second temperature) (°C) (A) and after five weeks for nitrate (NO3), ammonium (NH3), and sulfate (SO4) content (+1 SE) of strains grown at 2.5°C following acclimation at 7.5°C, and of strains grown at 7.5°C following acclimation at 2.5°C (B).
