4. (A ) Growth rates across the entire time series and
(B ) for the first 8 days of the experiment (initial growth
rates) of the three species for each composition separately. Means and
associated standard errors across all Zn treatments (including no Zn)
are presented. For initial growth rate, the interaction between
composition and concentration was not significant, but for total growth
rate it was (Table S2). Dashed lines are drawn to visualize the
difference between the isolated setting and the two different pairings.
