  1. The proportion of successful excavations of camellia pericarps by camellia weevils was regressed on camellia pericarp thickness for each population. In each model, generalized linear mixed model with binomial error and a logit-link function was constructed. Individual camellia trees and each fruit nested within trees were fitted as random terms to avoid overdispersion. Trees with no trial holes were excluded from the analysis.
  2. *Significant after sequential Bonferroni correction (α = 0.05).
