Redundancy Analysis (RDA) relating patch-network and matrix gradients performed for the 69 land mosaics including suitable habitat for water voles.

Bi-plot of the first two canonical axes of patch-network (H1, H2, H3) and matrix gradients (M1, M2, M3). Patch-network variables and sites were scaled symmetrically by the square root of eigenvalues. Eigeinvalues for axis 1 = 0.304, and axis 2 = 0.059. Habitat-matrix correlations for the first two axes were 0.996 and 0.942. Explained variation was 0.37, pseudo-F = 3.01, p = 0.01. Effects of matrix characteristics on patch-network structure were significant in respect to irrigated agriculture (M1, p<0.01) and pasture intensification (M2, p = 0.02), but not significant regarding forest plantation (M3, p = 0.827).
