Variation in foliar damage from herbivores in Colorado environments. In low (panels A + B) and high (panel C) elevation gardens, leaf damage was positively correlated with source elevation, indicating that high elevation populations are more susceptible to damage by insect herbivores across test sites. The elevation of the garden is indicated on the X-axis with closed star at 2891m for low elevation, and an open star at 3133m for high elevation (panels A-C). In addition (D), foliar damage varied with geographic distance for the 2012 cohort across both gardens; data points from the low elevation garden are closed triangles and data points from the high elevation garden are open circles. Shading around predicted regression lines indicates 95% Confidence Intervals.
