“…Eastern chipmunks make both larder and scatter hoards (23,100), apparently choosing the type that optimizes foraging under each set of conditions (58). In controlled laboratory conditions, individuals vary their levels of fat deposition (15,86,100), the amount of stored food (15,65), and their storing method (in larder or scatter hoards; 65) in response to environmen tal variables. The length of torpor varies among individuals (15,86,133).…”
