Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors.

- Urbanization is increasingly studied for its effects on species movement and gene flow, particularly focusing on how native species adapt or thrive in urban settings.
- Researchers investigated the genetic structure and gene flow of two small mammals (white-footed mice and big brown bats) with differing dispersal abilities in the Providence, Rhode Island metropolitan area.
- The study found that urbanization significantly impacts mice, leading to reduced migration and inbreeding, while bats maintained strong genetic connectivity due to their ability to fly, highlighting the importance of dispersal capacity in urban ecology.
