Overview

Examines thermal tolerance in a beetle across altitudinal gradients, highlighting adaptive responses to climate change.

Key Points

  • The research aims to investigate how temperature and aridity influence the thermal limits and morphological traits of a carabid beetle along different elevations.
  • Measured upper thermal limits (CTmax and ULT) in beetle populations at three altitudes
  • Assessed body size and water loss/body size ratios
  • Analyzed intraspecific variation in physiological traits across elevations
  • CTmax and ULT decreased with elevation, indicating lower thermal limits at higher altitudes
  • Body size also declined with elevation, with low-elevation populations being larger and more heat-tolerant
  • Water loss relative to body size increased with elevation, suggesting higher desiccation stress in higher populations
