<p>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<i>-F</i> = 3.01, <i>p</i> = 0.01. Effects of matrix characteristics on patch-network structure were significant in respect to irrigated agriculture (M1, <i>p</i><0.01) and pasture intensification (M2, <i>p</i> = 0.02), but not significant regarding forest plantation (M3, <i>p</i> = 0.827).</p>
