There are two major strategies available to mammals to survive winter: hibernation, where large animals drop their metabolic rate, and non-hibernation, where small mammals utilise fat stores to maintain their body temperature. According to Stuart Egginton from the University of Birmingham, textbooks state that the liver is the main organ of heat generation, 'but this is based purely on the relative mass,' he explains. Egginton realised that the liver could only be a thermogenic organ if it generated more heat than expected for its size. Egginton, David Hauton and Andrew Coney decided to test the liver's lipid oxidation profile to find out whether the liver really does keep non-hibernators warm during winter.
