Figure 5From: Molecular subdivision of the marine diatom Thalassiosira rotulain relation to geographic distribution, genome size, and physiologyPhysiological Experiments. Black lines represent lineage 1, grey lines represent lineage 3. a) Growth rates for six strains at 4, 10, and 17.5°C, high light (112 μmol photons m-2 s-1) b) Growth rates for six strains at 4, 10, and 17.5°C, low light (50 μmol photons m-2 s-1).Back to article page
