Plug size
Figure 1: Female plug area after one mating. Plug size does not differ comparing females
from the different treatments and replicates. Plug size area mean and quartiles. The different
shades of grey represent the different replicate lines (A, B, C, D) of the two sex ratio
treatments and the starting population (PA, PG; SP8).
Figure 2: Plug area produced by males after one mating. Plug size does not differ comparing
males from the different treatments and replicates. Plug size area mean and quartiles. The
different shades of grey represent the different replicate lines (A, B, C, D) of the two sex ratio
treatments and the starting population (PA, PG; SP8).
Sperm size
Figure 3: Sperm cell volume of males. Males from different treatments and replicates do not
differ in sperm cell volume. Male sperm cell volume mean and quartiles. The different shades
of grey represent the different replicate lines (A, B, C, D) of the two sex ratio treatments and
the starting population (PA, PG; SP8).
Lifetime Reproductive Success I
Figure 4: Lifetime production of offspring calculated per female. Females and males were
kept in a 5:5 sex ratio and offspring was counted over lifetime. Overall, polyandrous females
produced more offspring than either polygynous females or females from the SP8. Mean and
quartiles of offspring number. The different shades of grey represent the different replicate
lines (A, B, C, D) of the two sex ratio treatments and the starting population (PA, PG; SP8).
Figure 5: Lifetime production of offspring calculated per female. Females and males were
kept in a 5:5 sex ratio and offspring was counted over lifetime. Males do not differ in
offspring produced neither between treatments nor replicates. Mean and quartiles of offspring
number. The different shades of grey represent the different replicate lines (A, B, C, D) of the
two sex ratio treatments and the starting population (PA, PG; SP8).
Lifetime Reproductive Success II
Figure 6: Lifetime production of offspring calculated per female. Females and males were
kept in a 5:1 and 1:5 sex ratio resembling original treatment conditions. Offspring was
counted for the first three days after mating. Overall, polyandrous females produced more
offspring than polygynous females, but females from the SP8 produced more offspring than
either PA or PG. Mean and quartiles of offspring number. The different shades of grey
represent the different replicate lines (A, B, C, D) of the two sex ratio treatments and the
starting population (PA, PG; SP8).
Figure 7: Lifetime production of offspring calculated per female. Females and males were
kept in a 5:1 and 1:5 sex ratio resembling original treatment conditions. Offspring was
counted for the first three days after mating. Males do not differ in offspring produced neither
between treatments nor replicates. Mean and quartiles of offspring number. The different
shades of grey represent the different replicate lines (A, B, C, D) of the two sex ratio
treatments and the starting population (PA, PG; SP8).
