Proportion of propagules from source A between the sources. Proportion of propagules from source A as a function of position x between -300 m and 300 m for three dispersal kernels:hatched line, Gaussian kernel; solid line, exponential kernel; long-hatched line, power-law kernel with a = 3. The mean distance travelled is the same for the three kernels and equals 10 m (parameter α equals respectively 17.7, 10 and 10).
