Overview

Global analysis shows larger body size increases urban tolerance in plants, indicating species responses vary greatly.

Key Points

  • Many species in urban environments tend to avoid urban settings, while only a few thrive, pointing to significant biodiversity change.
  • Our analysis identified a consistent relationship where larger body sizes were typically linked to greater urban tolerance, especially in plants.
  • The study utilized a global framework involving over 30,000 species to better understand urban filtering and biodiversity responses.
  • Findings emphasize the need for tailored urban planning to enhance biodiversity within rapidly urbanizing landscapes.
