Day versus night and the evolution of sexual dimorphism in Lepidoptera Open
Many species exhibit consistent morphological differences between males and females. This sexual dimorphism sparked debate between Charles Darwin, who attributed it to sexual selection favoring male traits that appeal to females, and Alfre…

Loss of a morph is associated with asymmetric character release in a radiation of woodland salamanders Open
Color polymorphism, the occurrence of discrete color morphs with co-adapted sets of traits within the same population, may provide the raw materials for rapid species formation. The fixation of a morph can result in character release, wher…
