Fig. 5: Evolution of sensing and site-specific dispersal
with increasingly severe environmental variability. By mapping the size
of the regions in Figure 4 with a change in severity (v), it is apparent
that with an increase in v, there is greater potential for site-specific
dispersal to evolve. With an increase in \(\mu\) (fig. 5b), the
potential for site-specific dispersal to evolve is limited to high
values of v, demonstrating the importance of v as a driver for this
effect. Variables used: v = 0 – 23, S1 = 18, S2 = 0 – 23, f = 5, c =
0, \(\mu\) in 5a = 0, \(\mu\) in 5b = 0.1.
