Chitinase activity in artificial selection experiment 1. a Enzymatic activity measured over 20 generations. Each point represents the mean of the positive selection communities (n = 30) from which the mean of the randomly selected controls (n = 30) was subtracted. The black dotted line (zero) represents where chitinase activity of the positive selection is equal to that of the random selection. b Chitinase activity measured within the incubation period of generation 15 of the 9-day incubation. c Chitinase activity and DNA concentration of the positive selection measured within the incubation period of generation 20 of the 4-day incubation. Each point in panels b and c represents absolute chitinase activity measured in the positive (red) and random selection (blue). Arrows in panel a indicate the generations in which the regular monitoring of chitinase activity was performed, i.e. shown in panels b and c
