Table 1.

Broad sense heritability for lifetime fitness and foliar damage from herbivores in three gardens and two cohorts. There is no high elevation 2011 cohort in Colorado (NA=Not applicable). P-values in bold are significant after Bonferroni correction for multiple tests (α=0.005), and the italicized p-value is marginally significant at that level.
