The roles of inter- and intra-sexual selection in behavioral isolation between native and invasive pupfishes [PDF]

open access: yes, 2017
Male-male competition and female mate choice may both play important roles in driving and maintaining reproductive isolation between species. When previously allopatric species come into secondary contact with each other due to introductions, they ...
