(A) Fixation probability, Pfix, depending on selection strength, s and variability 
according to Eq. (1). In the green regime where 
the faster growing trait is favored while in the gray regime the less sensitive species has an advantage. The black line indicates the parabola 
, which is our prediction for 
. The dashed gray line corresponds to a condition for the survival of a non-competing species derived by May18. (B) Comparison of our analytic calculations for the fixation probabilities (Eq. (6)) and the full two species model (Eq. (1)) for 
in {red, violet, blue, green}. Other parameters are
