TABLE I3. Partial Mantel correlations (r) between macroinvertebrate community dissimilarity and three different distance models for invertebrates with a generation time < 1 year and generation time > 1 year of pond group 1 and 2 corrected for environmental dissimilarity. P values were obtained after 9,999 randomizations. Significant correlations are in bold.
