We used biophysical modeling to simulate annual activity time under two vegetation cover scenarios corresponding to these urban and non-urban environments. Despite finding similar body and preferred temperatures in the two populations, lizards from the urban site were larger, showed lower critical thermal values, and were more effective in thermoregulation, as measured by their lower deviation from preferred temperature. Lizards from the urban site also likely had more hours of activity across the year, likely due to warmer conditions associated with the urban heat island effect. While these traits may offer short-term advantages, continued increases in temperature could reduce daily activity windows and challenge persistence in this urban site.

Animals experience two fundamentally different environments across the diel cycle, as diurnal and nocturnal periods contain different conditions around which animals must partition their space use. This partitioning is partially a consequence of animals needing to meet different demands across the diel cycle. Abiotic conditions can interact with biotic pressures to cause animals to respond differently to compounding pressures such as thermal stress between the diurnal and nocturnal periods. The chestnut-bellied scaled quail (<em>Callipepla squamata</em> var. <em>castanogastris</em>) is a shrubland-obligate subspecies of scaled quail within the Tamaulipan thornscrub biotic province that has faced population declines in recent decades. Our objectives were to examine the space use of GPS-tagged chestnut-bellied scaled quail at two sites in South Texas (one stable and one declining population) and to predict how habitat suitability shifts across the diel cycle. Additionally, we determined how changes in habitat suitability may be impacted by ambient temperature as well as landscape configuration. While diurnal and nocturnal environmental suitability overlap was relatively high at most temperatures (Schoener's <em>D</em>: 0.67–0.81 [stable site]; 0.70–0.87 [declining site]), we found that overlap decreased by 15 % (stable population site) and 22 % (declining population site) when ambient temperatures reached the upper limit of the species' thermoneutral zone (35 °C).
