Better understanding how organisms respond to their abiotic environment, especially at the biochemical level, is critical in predicting population trajectories under climate change. In this study, we measured constitutive stress biomarkers and protein post-translational modifications associated with oxidative Gallotia galloti , an insular lizard species inhabiting highly heterogeneous environments on Tenerife. Tenerife a small volcanic island relatively isolated archipelago off West coast of Africa. We found that expression GRP94, molecular chaperone protein, levels carbonylation, marker cellular stress, change across different environments, depending solar radiation-related variables topology. Here, report wild animal population, cross-talk between baseline heat shock protein-like GRP94 damage (protein carbonylation), which are influenced by range available temperatures, quantified through modelled operative temperature. This suggests dynamic trade-off homeostasis lizards adapted thermally topologically environment.
