Sex-specific morphological shifts across space and time in replicate urban wall lizard introductions

As species move into new environments through founder events, their phenotypes may diverge from native populations. Identifying the drivers underlying such variation and the constraints on the adaptive potential of this variation is essential for understanding how organisms respond to new or rapidly changing habitats. Such phenotypic divergence may be especially evident in populations introduced to new environments via human-assisted transport or in dramatically altered environments such as cities. Sexually dimorphic species beg the additional questions of how these new environments may influence the sexes differently and how dimorphism may shape the range of potential responses. The repeated translocation, establishment, and spread of wall lizards (Podarcis spp.) from native European populations to new locations in North America provide an excellent natural experiment to explore how phenotypes may differ after establishment in a new environment. Here, we quantify body shape and the mul..., , # Sex-specific morphological shifts across space and time in replicate urban wall lizard introductions
