    ..This, in turn, slightly reduced seed germination. Overall, these results shed light, for the first time, on the potential indirect effects of alternative resources on the fate of diaspores adapted for ant dispersal...

    ..This approach may be extended to any organism dispersing offspring to different environments...

  5. Boulay R, Coll Toledano J, Manzaneda A, Cerda X. Geographic variations in seed dispersal by ants: are plant and seed traits decisive?. Naturwissenschaften. 2007;94:242-6 pubmed
    ..Although myrmecochory has long been considered a diffuse interaction, our results support the idea that, at local scale, a limited number of ant species may be decisive to its evolution...
  6. Boulay R, Carro F, Soriguer R, Cerda X. Synchrony between fruit maturation and effective dispersers' foraging activity increases seed protection against seed predators. Proc Biol Sci. 2007;274:2515-22 pubmed
    ..We argue that traits allowing synchrony between seed presentation and effective partners may constitute a crucial pre-adaptation for the evolution of plant-animal mutualisms involving numerous animal partners...
  7. Boulay R, Carro F, Soriguer R, Cerda X. Small-scale indirect effects determine the outcome of a tripartite plant-disperser-granivore interaction. Oecologia. 2009;161:529-37 pubmed publisher
    ..They highlight the indirect effect of cheaters that are likely to interfere in mutualisms and may lead to their collapse unless external factors such as spatio-temporal heterogeneity in seed availability constrain their effect...
