Definitions of the MRPP statistics: A is a measure of effect size and represents the within-group homogeneity; T is a statistic describing the separation between the groups; and P is the P-value for significance test of homogeneity using permutation. Habitat code: CDTK = Chuandong Tiankeng; SMTK = Shenmu Tiankeng; FORE = Forest Remnants; FENG = Fengshui Woods.
