The population consequences of sexual selection remain empirically unexplored. Comparative studies, involving extinction risk,
have yielded different results as to the effect of sexual selection on population densities make contrasting predictions. Here,
we investigate the relationship between sexual dimorphism (SD) and population productivity in the seed beetle Callosobruchus
maculatus, using 13 populations that have evolved in isolation. Geometric morphometric methods and image analysis are employed
to form integrative measures of sexual dimorphism, composed of variation in weight, size, body shape, and pigmentation. We
