Faced with climatic extremes, desert species may be at increased risk of depleting water and energy reserves in summer, thus, understanding their thermal ecology and microhabitat use is more crucial than ever to predict responses to climate change. Like many species, desert tortoises (Gopherus agassizii) utilize burrows as refugia from high daytime surface temperatures to avoid overheating and conserve energy and water. However, nighttime temperatures are lower at the surface than in burrows, particularly in smaller, less ventilated burrows. This raises the question of whether juvenile tortoises will shift from using burrows at night to overnighting at the surface to reduce energy expenditure in hotter seasons. Cameras can address this question, but they are limited by tortoise movements among burrows and do not provide key information on temperature. In August of 2023, we observed juvenile tortoise activity in the wild using time-lapse cameras and simultaneously recorded tortoise and environmental temperatures using temperature loggers (iButtons) affixed to juveniles and positioned in burrow and surface microhabitats. We will use camera data to assess whether temperature data from tortoises and burrow and surface environments can be used to reliably estimate nighttime microhabitat use and potential activity shifts in response to climate change.
