Climate shifts may force lizards to adapt movement habits

Climate change is reshaping the daily routines of ocellated lizards, a large reptile species native to Mediterranean regions, according to a recent study. These lizards, known as *Timon lepidus*, rely heavily on temperature to regulate their body functions, making them particularly vulnerable to shifting environmental conditions.

The research, led by Antigoni Kaliontzopoulou from the University of Barcelona, examines how rising temperatures influence their mobility. While some lizards, termed 'generalists,' maintain flexibility in movement even at higher temperatures, others, called 'specialists,' struggle to keep up, reducing their ability to access food, shelters, and escape predators.

Kaliontzopoulou explains that generalist behavior may offer long-term advantages in adapting to warming climates, but it also increases exposure to predation risks. The study combines physiological, behavioral, and environmental data to show how climate shifts could alter the spatial and timing patterns of ectothermic animals like lizards.

The findings highlight lizards as key models for understanding how rising temperatures affect species that depend on external heat. The research underscores the need for conservation strategies that account for these behavioral shifts, particularly for species already adapted to specific microclimates.

Co-authors included researchers from the University of Porto and the Czech Academy of Sciences, publishing their work in the *Journal of Animal Ecology* in 2026. The study’s insights could inform broader conservation efforts for other ectothermic species facing similar environmental pressures.
