The effect of the river to the movements of the false heath fritillary in the study landscape. The graph shows probability of simulated male (left hand panels) and female (right hand panels) false heath fritillaries to reach a target patch (blue; pointed with an arrow, located on the Eastern side of the river) within its lifetime, as a function of its place of birth. The results are shown for the riparian landscape in which the river has been modelled as an independent habitat type (panels A-B) and another version of this landscape, in which the river has been modelled as part of the low-quality matrix (panels C-D). The difference of the probabilities (results of panels A-B minus those of C-D) has been plotted separately (panels E-F): from the green (purple) areas, the simulated false heath fritillaries are more (less) likely to reach the target patch if the river was modelled as an independent habitat type. Parameter values set to the posterior median values of the generalised movement model.
