Figure 1
Graphical description of the model (panel A) and an example scenario in which fluctuating selective optima θ1(t) and θ2(t) fluctuate over time (panel B).
In this particular scenario, optimum 
is delayed relative to 
with phase shift φ and 
contains noise (indicated by noise parameter d). The amount of noise in 
is proportional to the disturbance parameter d. Parameters: 
.
