Cache pilferage by competitors is thought to drive the evolution of
hoarding behavior in animals, which plays significant roles in tree
regeneration and formation of mutualisms between trees and animals.
However, little is known how cache pilferage risk among seeds of different
tree species or years affects hoarding behavior and seed dispersal by
animals. We hypothesized that scatter-hoarding rodents could adjust
hoarding behavior according to variation in cache pilferage risk among
seeds and years to minimize cache pilferage, by investigating the
relationship between cache pilferage risk and seed dispersal of seven tree
species over three years in tropical forest in southwest China. Among
years, high pilferage risk was related to high probability of
larder-hoarding and short periods of scatter-hoarding; whereas, the
probability of scatter-hoarding was higher in intermediate pilferage year
than in both low and high pilferage years. Among seeds, high pilferage
risk was related to low probability and short periods of scatter-hoarding.
Our results indicated that cache pilferage risk significantly affected
hoarding behaviors and seed dispersal by scatter-hoarding rodents as well
as seed fates. Cache pilferage risk was a reliable explanatory factor for
variation in seed dispersal, and it might be an important driving force in
the evolution of rodent hoarding behaviors and seed characteristics.
