Contrasting physiological responses to habitat degradation in two arboreal mammals

Summary: To cope with the challenges presented by habitat degradation and loss, animals must often respond by adjusting physiological and behavioral mechanisms. Here we quantified physiological and behavioral traits, including body temperature and food consumption, of two mammals with differing ther...
