Fig. 1

Schematic representation of SiMRiv’s algorithm for incorporating local landscape influence on movement behavior. The figure shows how resistance values of the landscape within the perceptual range are locally “perceived” by the organism whose movements are to be simulated, and how they affect its movement in respect to its decision about the heading to be taken at the next step. Note that in the current software version the landscape also influences the length of the step, which is not illustrated here (but see Additional file 1)
