Fitted interpolation lines of predicted total root length (a), volume (c), and number (e) values for the ranges of PatchDiam and the trait value for tree C1 determined using AMAPmod (optimum length = 13.8, volume = 31.8, number = 46). Optimum PatchDiam for all ten trees for length (b), volume (d), and number (f) with tree C1 shown as white circles
