Frank Van de Meutter, Luc De Meester, and Robby Stoks. 2007. Metacommunity structure of pond macroinvertebrates: effects of dispersal mode and generation time. Ecology 88:1687–1695.

Appendix J. Tables showing the results of the variance partitioning and partial Mantel correlations between macroinvertebrate community dissimilarity and three different distance models for active dispersers with a short (<1 yr) and long (>1 yr) generation time.

TABLE J1. Variance partitioning and associated P values of the invertebrate data of pond group 1. Data include active dispersers with a short (<1 yr) and long (>1 yr) generation time in 2001–2003. E = variation explained by environmental variables, S = by spatial variables, E|S = pure environmental variation, S|E = pure spatial variation, ES = variation shared between E and S. Subscripts indicate whether the Euclidian land model (land) or water model (water) was used as S. Significant pure proportions are in bold.

TABLE J3. Partial Mantel correlations (r) between macroinvertebrate community dissimilarity and three different distance models. Data included are from actively dispersing macroinvertebrates of pond group 1 and 2 with either a generation time < 1 year or a generation time > 1year. P values were obtained after 9,999 randomizations. Significant correlations are in bold.
