水果气味已经进化成植物和灵长类动物之间传播种子的沟通渠道。在很大程度上,花和果实性状的巨大多样性是通过动物传粉者和种子传播者促进植物繁殖的一系列适应。然而,水果气味究竟是果实成熟的副产品,还是与动物共生的进化交流渠道,目前尚不清楚。我们发现,在专门通过狐猴(一种嗅觉导向的灵长类动物)传播种子的物种中,果实比主要通过鸟类传播种子的同属物种更能增加气味的产生,并显著改变它们的化学成分。我们进一步表明狐猴利用这些水果气味的变化来识别成熟的水果。这些结果表明,水果气味是促进动植物共生的一种进化的交流系统。
Fruit scent has evolved as a communication channel between plants and primates that disperse their seeds. The tremendous diversity of floral and fruit traits is, to a large extent, a set of adaptations that promote plant reproduction through animal pollinators and seed dispersers. Yet, it is still unknown whether fruit scent is a by-product of fruit maturation or an evolved communication channel with animal mutualists. We show that in species that specialize on seed dispersal by lemurs—an olfactorily oriented primate—fruits increase scent production and change their chemical composition significantly more than sympatric species whose seeds are largely dispersed by birds. We further show that lemurs use these shifts in fruit scent to identify ripe fruits. These results show that fruit scent is an evolved communication system that facilitates animal-plant mutualism.
