Short summary

We found that the modelled annual carbon balance of biocrusts is strongly affected by both the environment (mostly air temperature and CO₂ concentration) and physiology, such as temperature response of respiration. However, the relative impacts of these drivers vary across regions with different climates. Uncertainty in driving factors may lead to unrealistic carbon balance estimates, particularly in temperate climates, and may be explained by seasonal variation of physiology due to acclimation.
