Appendix D. PLSPM results.

Table D1. Total, direct, and indirect effect of environmental variable (E.V.) on each Layman’s metric for both densities of immature and mature fish. 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. ^ denotes nonsignificant path coefficient.
