Spear-headed by Old Dominion University grad student and seed dispersal aficionado Spencer Schubert, this paper describes an experiment in which we investigated the context-dependence of post-dispersal predation of acorns on microhabitat and annual variation in acorn crops. We show that the probability of surviving post-dispersal predation is lowest in areas with dense rodent populations (chaparral) and that it's risky to be cached below trees that had acorns in a given year. Such context-dependence can thus have a strong effect on oak regeneration, as well as jay caching behavior.
