Abstract

Rodents adjust predation and hoarding behavior according to the probability of their hoarding seeds being stolen by competitors. Rodents eat unsafe seeds (seeds more likely to be stolen) immediately and keep safe seeds (seeds less likely to be stolen) for a long time. Rodents spread their seeds in many small “storehouses†when the probability of hoarded seeds being stolen is high and hoard many seeds in one “storehouse†when the probability is low.
