Extended Data Fig. 2: Time series of mean zooplankton body size and microalgae biovolume following ecological perturbations.
From: Predator mass mortality events restructure food webs through trophic decoupling
Mean zooplankton body size (mm, A) and microalgae biovolume (ln[μm2], B) following predator mass mortality events (MMEs, light green), predator removals (light blue), and resource pulses (dark green), as well as the undisturbed system (control, dark blue). Points and lines indicate mean values and +/− 1 SE for each sampling period and treatment, with points jittered to reduce overlap within sample periods. Solid lines and shaded regions indicate model predictions and 95% confidence intervals, respectively. Relative to the control, MMEs (t8 = 8.42, p < 0.01), predator removals (t8 = 6.29, p < 0.01), and resource pulses (t8 = 4.99, p < 0.01) increased mean zooplankton body size. MMEs (t15.06 = 2.58, p = 0.02) and predator removals (t15.06 = 2.48, p = 0.02), but not resource pulses (t15.06 = 1.32, p = 0.19), increased mean microalgae biovolume. Dashed lines indicate when perturbations were induced (i.e., live fish and/or fish carrion added and/or removed). Data were analysed from 355 biologically independent zooplankton samples (A) and microalgae samples (B) for a control (n = 96), predator removal (n = 80), resource pulse (n = 80), and MME (n = 99), respectively, from one experiment. General additive mixed model (GAMM, A-B).
