Differences in adult sex ratios (ASR, proportion of males) among scenarios. Each box plot shows the distribution (thick middle line: median, box: interquartile range; whiskers extend to the most extreme data points within 1.5 × interquartile range from the box) across 100 runs for the year when mean ASR across 5 consecutive years first exceeded 0.6, starting with either XX/XY or ZW/ZZ system (a), and the mean ASR during the transition period between the initial ZW/ZZ and the subsequent XX/XY system (b). Significant pairwise differences are indicated above the box plots as: * p < 0.05, ** p < 0.01, *** p < 0.001 (for details see SI1 Table S3). Generation time was 3 years. Year zero refers to the start of climate warming
