abstract = {Modern sexual selection theory indicates that reproductive costs rather than the 

operational sex ratio predict the intensity of sexual selection. We investigated sexual 

selection in the polygynandrous common lizard Lacerta vivipara. This species shows male 

aggression, causing high mating costs for females when adult sex ratios (ASR) are malebiased. 

We manipulated ASR in 12 experimental populations and quantified the intensity 

of sexual selection based on the relationship between reproductive success and body 

size. In sharp contrast to classical sexual selection theory predictions, positive directional 

sexual selection on male size was stronger and positive directional selection on female 

size weaker in female-biased populations than in male-biased populations. Thus, 

consistent with modern theory, directional sexual selection on male size was weaker in 

populations with higher female mating costs. This suggests that the costs of breeding, 

but not the operational sex ratio, correctly predicted the strength of sexual selection.},
