Metabolic rate interacts with resource availability to determine individual variation in microhabitat use in the wild ...
Ecological pressures such as competition can lead individuals within a population to partition resources or habitats, but the underlying intrinsic mechanisms that determine an individual’s resource use are not well understood. Here we show that an individual’s own energy demand and associated compet...
