Supplemental Information

Table S1. PRNG seeds used for the NetLogo replications

Each seed was obtained by taking the MD5 checksum of replication number and converting the resulting hexadecimal string to a 32-bit integer (the maximum precision accepted by NetLogo).

Tables S2.1 to S2.10. Statistics and distributional analysis of the selected focal measures for n = 30 replications of the PPHPC model for all the model size and parameter set combinations

‘SW‘ refers to the p-value produced by the Shapiro-Wilk normality test. ‘Skew.‘ refers to the skewness in the distribution. ‘Hist.‘ shows an histogram of the distribution. ‘Q-Q‘ shows a Q-Q plot of the distribution.

Outputs of 30 replications for all model sizes and parameter set 1

Each text file corresponds to one replication. Columns correspond to outputs in the following order: prey population, predator population, available cell-bound food, mean prey energy, mean predator energy, mean value of the grid cells C state variable. Rows correspond to iterations.
