Fig. 2

Species richness (a through j) for all sites, and abundance (k through o) for low elevation sites (abundance data were only collected at the low sites). Two letter site names and colors follow Fig. 1a. In all panels, patterns are visualized with both a spline fit with five degrees of freedom (thin black line) and predicted values from random forest analysis (thick gray line) incorporating variation in sampling effort. In panels k through o, values plotted are z-standardized values of total abundance (number of individuals) per year averaged across species
