Fine-scale spatial variation in eastern grey squirrel melanism across a complex urban landscape.

The Journal of animal ecology - 1 Sept 2026

Dinh Francis Quang-Hai, Richmond Isabella C, Hendry Andrew P, Roth Allison M

Abstract excerpt

Urban environments impose novel selective pressures that can drive rapid phenotypic and genetic change in wild populations. While previous studies have focused on broad urban-rural contrasts or cross-city comparisons, less is known about how phenotypic traits vary across fine spatial scales within cities, where environmental gradients and geographic features may create localized heterogeneity. We studied spatial...
