Fig. 2.

Responses to selection and selection differentials over time for intrinsic growth potential (diameter at age 27 y) based on (A) fitness (survival) at each sampling time (black lines, closed and open circles, respectively) and considering the outbreak as a single period (gray lines, closed and open triangles, respectively) and (B) cumulative fitness. Bars are 95% credibility intervals (for clarity, credibility intervals before the outbreak are only shown for responses to selection). An asterisk (*) denotes significant selection responses; an “x” denotes significant selection differentials.
