Article Synopsis
  • - Urbanization significantly impacts global environmental change and can influence evolutionary processes in species by causing habitat fragmentation and small population sizes, as seen in the eastern grey squirrel (Sciurus carolinensis).
  • - Genetic analysis of 403 eastern grey squirrels revealed moderate genetic diversity and low inbreeding, showing higher migration and genetic connectivity in urbanized areas compared to more fragmented agricultural landscapes.
  • - The study suggests that while urban areas can disrupt gene flow, eastern grey squirrels have maintained connectivity across these regions, particularly where tree cover is present, indicating that landscape composition plays a critical role in wildlife adaptation to urbanization.

Terrestrial carnivores are among the most imperiled species worldwide, yet some species are resilient and are recovering in human-dominated landscapes after decades or centuries of absence. Bobcat () populations were extirpated from much of Midwestern US in the mid-1800's, and are currently expanding and recolonizing their former range. In this study, we investigated multi-scale habitat selection for Ohio's expanding bobcat population, and examined habitat connectivity in order to evaluate the conduits for dispersal statewide.
