Fig. 5: The Competition-Selection model prediction and experimental observations of changes in growth rate under co-cultivation.
From: Intraspecific variation in metal tolerance modulate competition between two marine diatoms
Solid lines in (A, C) show the dose-response predicted modeled outcome and (A, B) the observed changes of species-specific growth rate during the competition experiment. As a point of reference, the species averages are shown as dashed lines across both panels. The upper panel of graphs (A, B) corresponds to T. baltica, and the lower (C, D) to S. marinoi. The Competition-Selection model assumes no interaction between species or strain and no acclimatization or development of chronic toxic effects, only selection based on variability in inhibition predictions from dose–response curves (A and C). Observation data show specific growth rate observations computed based on microscopy observations on days 0, 4, 7, and 10 (N = 3) of the competition experiment (B and D). Note that statistical tests have been performed on inhibition data computed from growth rates as shown in (B and D) (see Table 1).
