Figure 1.
Maximum growth rate of A) Serratia marcescens B) Novosphingobium capsulatum.
Growth rates were measured during a weeklong fitness assay. The bars show the estimated marginal mean growth rates (h-1) based on the GLMM + SE. The sampling time of bacterial clones is indicated on the x-axis: after 1 week = bacteria have a weeklong evolutionary history in the pulsed resource environment; after 13 weeks = evolutionary history is 13 weeks. The reference lines on the background indicate the mean maximum growth rate (dark grey line) ± SE (light grey lines) of the ancestral clones. Treatments: 1 species = species has grown in monocultures; 2 species = species has grown in two-species community; large pulse = 99,9 % of the total batch culture volume was renewed weekly; small pulse = 70% of the batch culture volume was renewed weekly.
Figure 2.
Yield of A) Serratia marcescens B) Novosphingobium capsulatum.
Yield is measured as optical density, and corresponds to the total maximum biomass measured during a weeklong fitness assay. The bars show the estimated marginal mean yield based on the GLMM + SE in all treatments. Treatments are the same as in Figure 1.
Figure 3.
Mortality of A) Serratia marcescens B) Novosphingobium capsulatum.
The mortality is calculated as proportional reduction in biomass during a weeklong fitness assay. The bars show the estimated marginal mean mortality based on the GLMM + SE in all treatments. Treatments are the same as in Figure 1.
Figure 4.
Biofilm production of A) Serratia marcescens B) Novosphingobium capsulatum.
Biofilm amount was measured at the end of a weeklong fitness assay. The bars show the estimated marginal mean biofilm amount based on the GLMM + SE in all treatments. Treatments are the same as in Figure 1.
