Now, the probability of mature sperm being present in the seminal vesicles declined in response to adult heat stress ( n = 336, β = −2.137 ± 0.315, Z = −6.780, p < 0.001), with a negative trend for developmental heat stress ( β = −0.503 ± 0.284, Z = −1.770, p = 0.076) and no effect of thermal tolerance ( β = −0.747 ± 0.582, Z = −1.282, p = 0.200; figure 3 a , electronic supplementary material, table S12).
