Fig. 3From: Impact of deforestation on habitat connectivity thresholds for large carnivores in tropical forestsRelationship between the percentage of natural vegetation (PLAND) and integral index of connectivity (IIC). Straight line represents the estimated regression equation based on a simple linear model (a). The dashed lines represent a piecewise linear regression model (where C = 58.4 is the threshold point and D is a dummy variable with D = 0 for C < 58.4 and D = 1 for C ≥ 1), and the vertical arrows represents the breakpoints identified using the Davies test (with ± se) (b)Back to article page
