Vulnerability to global warming of the critically endangered Añelo Sand Dunes Lizard (<i>Liolaemus cuyumhue</i>) from the Monte Desert, Patagonia Argentina

The body temperature of lizards is strongly influenced by the thermal quality microhabitats, exploiting favourable environmental temperatures, and avoiding exposure to extreme conditions. For these reasons, reptile populations are considered be especially vulnerable changes in temperatures produced climate change. Here, we study physiology critically endangered Añelo Sand Dunes Lizard (Liolaemus cuyumhue Avila, Morando, Perez Sites, 2009). We hypothesise that (i) there a coadaptation between optimal for locomotor performance L. its preference; (ii) lives an environment with low quality; (iii) rise due global warming will impose decrement speed represented lower tolerance narrower safety margins, increasing their already high vulnerability. recorded field (T b ), preferred pref operative e sensitivity locomotion at different temperatures. Our results indicate this lizard not currently under stress or exceeding limits, but it thermoregulating below T avoid overheating, increase higher than 3.5 °C affect use microhabitats direct sun exposure.
