4. Sexual Selection and Adaptation to Novel Environments
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : The work included in this thesis aims at exploring the environmental sensitivity of benefits and costs of sexual selection through a combined empirical and theoretical effort, to increase our understanding of the impact of environmental change on sexually reproducing populations.Can sexual selection promote adaptation to novel environments? Sexual selection for good genes should accelerate adaptation by granting higher reproductive success to individuals of high genetic quality. READ MORE
