Mate competition provides the opportunity for sexual selection which often
acts strongly on males, but also the opportunity for sexual conflict that
can alter natural selection on females. Recent attention has focused on
the potential of sexual conflict to weaken selection on females if male
sexual attention, and hence harm, is disproportionately directed toward
high over low quality females, thereby reducing the fitness difference
between these females. However, sexual conflict could instead strengthen
selection on females if low quality females are more sensitive to male
harm than high quality females, thereby magnifying fitness differences
between them. We quantify the effects of male exposure on low vs. high
quality females in Drosophila melanogaster in each of two environments
(“simple” and “complex”) that are known to alter behavioural interactions.
We show that the effects of male harm are greater for low compared to high
quality females in the complex but not the simple environment, consistent
with mate competition strengthening selection on females in the former but
not in the latter environment.
Female fitness dataThe data are provided as a .csv file. Each row reports,
for a given replicate, the survival (as a proportion) of the 35 females in
that replicate and the average fecundity of 10 randomly chosen surviving
females from that replicate. Total_fitness is the product of these.
Females were low or high quality (Quality) and experienced low or high
exposure to males (Male_exposure) in either a simple or complex mating
environment (Environment). The experiment was performed in two
blocks.MacPherson_data.csv
