摘要

Climate change is increasing the frequency and severity of short-term heat shocks that threaten the persistence of natural popu-lations.However,most work addressing the evolutionary conse-quences of anthropogenic environmental change has focused on natural selection,with less attention paid to the impacts on sexual selection.The conditions under which sexual selection operates is a topic of debate,but a generally observed pattern is that the oper-ational sex ratio(OSR)of a population is key to determining both the extent of competition for fertilizations and the scope for mate choice(Weir et al.2011).Therefore,if high temperatures affect the ratio of reproductive males to females in a population,this could in-fluence sexual selection.
