   FIG. B1. Biplot of species community analysis of spiders (Araneae) in Zurich (RDA, for details see methods) showing the first canonical axis on the x-axis and the second on the y-axis (n = 32). Selected environmental variables in bold arrows; for visibility only the species most correlated to the first two canonical axes are shown (dashed arrows); abbreviated species names (i.e., 3 letters of the genus and 3 letters of the species) see Appendix A, Table A1. Q = squared variable.

   FIG. B2. Biplot of species community analysis of spiders (Araneae) in Lucerne (RDA, for details see methods) showing the first canonical axis on the x-axis and the second on the y-axis (n = 32). Selected environmental variables in bold arrows; for visibility only the species most correlated to the first two canonical axes are shown (dashed arrows); abbreviated species names (i.e., 3 letters of the genus and 3 letters of the species) see Appendix A, Table A1.
