Fig. 2 in Modelling sympatric speciation by means of biologically plausible mechanistic processes as exemplified by threespine stickleback species pairs
Fig. 2 Relative fitness is a function of morphology T. Here fitness ¼ sinð 2p»TÞ 2 þ 1 (relative fitness varies between 1 and 2, i.e. two-fold). In model 3, we used a flat fitness function: fitness=1. In model 5, we used the above fitness function, well fitness ¼ sinð 2p»TÞ 2 þ 0: 5 as as: (relative fitness varies between 0.5 and 1.5, i.e. a threefold selection differential), and fitness ¼ sinð 2p»TÞ 2 þ 0: 25 (relative fitness varies between 0.25 and 1.25, i.e. a five-fold selection differential)
