This research axis explores how reptiles and amphibians regulate their body temperature (thermoregulation, Bouazza et al., 2016), maintain water balance (hydroregulation), select habitats, and reproduce within various environmental contexts. By combining physiological and field ecology, this area of study seeks to understand how these animals adapt in their natural environments. This includes examining their adaptive strategies for survival and reproductive success, particularly in response to environmental challenges such as global climate change (Sinervo et al., 2010). Fieldwork in this domain involves habitat selection studies, effective sampling methods, and understanding the life histories of these species (Dodd, 2016, 2009). Insights from this research are vital for conservation efforts, particularly in identifying critical habitats and understanding species distribution patterns.
