Table 5. Pre- and post-copulatory traits in males not subjected to cold shock.
Summary of the results from a two-factor mixed model ANOVA on (A) mating latency (B), copulation duration (C) mating success, (D) male fertility and (E) progeny production. Data considering selection regime (FSB and FCB) as the fixed factors crossed with block (1–5) as random factor. p-values in bold are statistically significant.
