A new article is now available in early view at the American Journal of Physiology, Regulatory, Integrative and Comparative Physiology. Here, we show that improvements in cold tolerance acquired through adult acclimation and acclimation during development are both associated with similar changes in ion and water balance. This integrative study was a collaboration among Heath MacMillan, Jonas Andersen, Volker Loeschcke and Johannes Overgaard. Read the abstract or download the paper here (sorry about the paywall!).
