Table B1. Mean values (in bold) and confidence interval (25–75%) for trophic metrics calculated on 103 simulations for Layman’s metrics for each population among sampling years. TA: total area, CR: δ13C range, NR: δ15N range, CD: mean distance to the centroid, NND: mean nearest neighbor distance, SDNND: standard deviation of nearest neighbor distance.
