Figure 3. Examples of evolutionary trajectories simulated from Equation (1) on the lattice environment.
The branching criterion (Equation (4)) is equal to 0.6 (a), 1.07 (b) and 7.5 (c). When it is lower than one, the generalist strategy is stable (a). Otherwise, the metapopulation splits into two sub-populations of specialists (b and c). Dashed line: theoretical singular strategy (
), solid lines: habitat optima (
and 
). Other parameters are: a: 
(

; b: 
(
and 
),

; c:
