Climate warming drives a temperate-zone lizard to its upper thermal limits, restricting activity, and increasing energetic costs [PDF]

open access: yes, 2023
Lizards are considered vulnerable to climate change because many operate near their thermal maxima. Exposure to higher temperatures could reduce activity of these animals by forcing them to shelter in thermal refugia for prolonged periods to avoid ...
