Overview

Study evaluates outcomes of thermal restrictions on Liolaemus pictus, indicating physiological adaptations in response to global warming.

Key Points

  • Increased thermal restrictions led to 41.7% reproductive loss in lizards, compared to 12.3% in controls.
  • Pregnant lizards experiencing thermal restrictions selected lower body temperatures yet maintained stable conditions.
  • Physiological trade-offs potentially buffer adverse effects of global warming on lizard reproduction.
  • Findings suggest population vulnerability of viviparous Liolaemids to rising temperatures and local extinction risks.
