Indirect interactions,such as mutualism with seed dispersers,between cofruiting plants that share dispersers could alter their competition.Here,we tested the hypothesis that tree species has more mutualisms with dispersers will dominate over its counter partner in wild apricot(Armeniaca sibirica)and wild peach(Amygdalus davidiana),two common cofruiting rodentdispersed shrubs and trees in northern China.A.
