Urban Life Shapes Genetic Diversity in the Green Anole, Anolis carolinensis.

ABSTRACT: Urbanisation presents unique environmental pressures that drive rapid evolutionary adaptations, particularly in species inhabiting fragmented and anthropogenised landscapes. In this study, we investigate the genomic differentiation between urban and non-urban populations of Anolis carolinensis, focusing on two main aspects: (1) the effect of habitat fragmentation on inbreeding and mutational load and (2) genomic adaptation to the urban habitat. We found that urban populations can exhibit a reduced mutational load, which is a direct consequence of systemic inbreeding. Using genome-wide scans of selection and analyses of genetic diversity, we identify key genomic regions exhibiting significant divergence between urban and non-urban populations. These regions are enriched for genes associated
