The impact of varying spatial structure in static and shaken insect homogenates on the fitness of rare pherotypes in competition experiments. (A) After 5 days of culture (when sporulation is complete), static cultures have produced visible biofilms, while shaken cultures are homogeneous. Note that shaken cultures also contain glass beads to prevent biofilm formation. (B) The relative fitness of rare (10% frequency) pherotypes I and III in competition with pp IV. Boxplots show the median fitness and first and third quartiles, as per Fig. 2.
