Overview

Randomized trial reveals body size changes in moth communities and populations due to urban warming, indicating diverse ecological responses.

Key Points

  • This research aims to understand how urbanization impacts body size in geometrid moths, examining both community and population levels.
  • Sampled geometrid moths along an urbanization gradient in a tropical Andean city.
  • Analyzed body size variation in relation to urban-heat-island intensity at community and population levels.
  • Community-level analysis showed a reduction in body size at high UHI intensity, consistent with the temperature-size rule.
  • Population-level changes showed varied trends, indicating opposing impacts of urban warming and habitat fragmentation depending on species.
