The presence of co-flowering species can alter pollinator foraging behaviour and positively or negatively affect reproductive success of individual species. Liao et al. investigate interactions between Pedicularis monbeigiana and a co-flowering species, Vicia dichroantha, and find that the presence of V. dichroantha facilitates pollination and increases female reproductive success of P. monbeigiana via effects both in terms of quantity (mitigating pollinator limitation) and quality (reducing geitonogamy).
