This conceptual model leads to strong hypotheses about the mechanisms underlying variation in insect cold tolerance, for example that variation in CCR may be driven by differences in ion-motive ATPase activity, or transcellular and paracellular pathways of water movement across gut epithelia. These findings provide new avenues of study in the physiological and genetic basis of adaptive variation in insect cold tolerance that will improve predictions of insect biogeography in a changing climate.
