Rodents could influence plant regeneration as both seed predators and dispersers.With the combination of both field and experimental(in cage and seminatural enclosure)conditions,we tested whether rodents could distinguish intact with weevilinfested acorns or not,and how strategy of rodent predators could be influenced by food abundance and environment,by offering two kinds of Quercus aliena seeds(including intact and weevilinfested acorns)in a subtropical forest of Foping National Reserve in Qinling Mountains,China,during the autumn from 2011 to 2013.
