Figure 6: Farmers dominate competitively over non-farmers at the individual level.
From: Social amoeba farmers carry defensive symbionts to protect and privatize their crops

Individual graphs of each non-farmer alone and mixed in chimera with a farmer at different frequencies. As farmer frequency increases in chimera with a non-farmer, 9 out of 10 non-farmers have significantly reduced spore production. We allowed 10 non-farmers to complete the social stage either alone (Cl=clonal or 100%) or mixed (Co=common or 95%, Eq=equal or 50%, or Ra rare or 5%) with farmers and determined the effect on the spores returned per initial cell of the non-farmer. Pairings and bacteria are shown in Table 2. Two independent replicas were performed; error bars equal s.e.m.
