Perception costs of reproduction can magnify sexual selection

2017

We outline two avenues for future research:(1) in model organisms (for example, D. melanogaster), manipulating perception costs in males of varying quality and subsequently testing whether this results in an increase or decrease of male fitness variance; and (2) comparing short-term (that is, no perception costs) versus long-term estimations of male fitness variance in single cohorts via meta-analysis or ad hoc behavioural experiments.
