Table 1. Sperm and egg length in relation to long-term selection and short-term exposure.

Line	Temperature	Sperm length	N	Egg length	N
30°C TSL	30°C	88.4 ± 5.2	40	615.4 ± 51.5	240
30°C TSL	38°C	81.9 ± 7.9	40	685.5 ± 42.2	240
38°C TSL	30°C	91.5 ± 4.9	40	638.4 ± 48.3	240
38°C TSL	38°C	85.5 ± 4.3	40	682.7 ± 42.7	240
KSS	30°C	89.3 ± 4.1	26	662.6 ± 39.4	180
KSS	38°C	84.3 ± 4.8	26	697.9 ± 48.4	180

Shown are mean, standard deviation and sample size (sperm: number of males; eggs: number of eggs) for sperm length and egg length measured in individuals from temperature selection lines (TSL) and the ancestral population (KSS), exposed to different temperatures from pupation onward (see main text and Figures 1–3).
