The impact of an increase (INC) or decrease (DEC) is defined if an estimated genetic response was higher or lower for the least, than the most, rainfall group (R1 vs. R3) in a given sampling year, or for R1 over the 2 sampling years, respectively. Also similarly defined was for temperature with the highest temperature group (T3) vs. the lowest temperature group (T1) in a sampling year, or with T3 over the 28 y. All of the estimated genetic responses are listed in SI Appendix, Tables S5–S18. *P < 0.05, **P < 0.01, ***P < 0.001.
