  1. aK = number of parameters, L = log-likelihood, R2 = adjusted R2, AICc = sample-size-corrected Akaike’s Information Criterion, and Δi indicates strength of support from the data in comparison to the best model (Δi < 2 = substantial support, 4 < Δi < 7 = considerably less support, and Δi > 10 = essentially no support; Burnham and Anderson 2002)
  2. bNE is a neighborhood model based on dbh and distance of nearby longleaf pine trees
