Four different components are shown: pure environmental fraction ([E|S]), pure spatial fraction ([S|E]), shared fraction of environmental and spatial effects ([E∩S]), unexplained fraction ([R]). Values shown in boldface type showed significant effects. *, **, and *** indicate significant effects at P < 0.05, 0.01, and 0.001, respectively. NS indicates that variation partitioning could not be conducted because the subset of environmental variable was lacking.
