Frank Van de Meutter, Luc De Meester, and Robby Stoks. Year. Metacommunity structure of pond macroinvertebrates: effects of dispersal mode and generation time. Ecology VOL: pp-pp.

Appendix H. Tables showing the results of the variance partitioning and partial Mantel correlations between macroinvertebrate community dissimilarity and three different distance models for actively and passively dispersing macroinvertebrates.

TABLE H1. Variance partitioning and associated P values of the macroinvertebrate data of pond group 1 for active and passive dispersers 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 spatial model. Significant pure proportions are in bold.

TABLE H3.
