背景：旨在了解自然界中植物多样性产生和组织过程的研究在生态学中有着悠久的历史。其中，通过传粉者选择和访花间接发生的植物-植物相互作用的研究一直是至关重要的。然而，目前的证据表明，植物可以通过异源花粉（HP）转移更直接地相互作用，这些相互作用是无处不在的，可以有很强的健身效果。HP的相互作用的强度也可以在空间上有所不同，与重要的影响花的进化和社会assembly.Scope：在了解植物群落的多样化和组织的异源花粉转移的作用的兴趣正在迅速上升。物种相互作用的强度存在空间差异，它们在形成多样性格局方面的作用也得到了充分的承认。然而，经过40年的研究，HP传输强度和影响的空间变化的重要性仍然知之甚少，因此，我们忽略了它在塑造当地和全球范围内的多样性模式的潜力。在这里，我开发了一个概念框架，并总结现有的证据，HP传输相互作用的空间变化的生态和进化后果，并概述未来的方向在这一领域的结论：在HP传输的变化的驱动程序在这里讨论说明了HP强度及其影响的地理变化的高潜力，以及在HP接收的进化反应。到目前为止，传粉媒介介导的植物-植物相互作用的研究几乎完全由授粉前相互作用的研究主导，即使它们的结果可以受到发生在柱头上的植物-植物相互作用的影响。因此，至关重要的是，我们充分评估的后果和上下文的依赖性HP传输的相互作用，以获得更全面的了解植物传粉者的相互作用中发挥的作用，产生和组织植物生物多样性。
Background: Studies that aim to understand the processes that generate and organize plant diversity in nature have a long history in ecology. Among these, the study of plant-plant interactions that take place indirectly via pollinator choice and floral visitation has been paramount. Current evidence, however, indicates that plants can interact more directly via heterospecific pollen (HP) transfer and that these interactions are ubiquitous and can have strong fitness effects. The intensity of HP interactions can also vary spatially, with important implications for floral evolution and community assembly.Scope: Interest in understanding the role of heterospecific pollen transfer in the diversification and organization of plant communities is rapidly rising. The existence of spatial variation in the intensity of species interactions and their role in shaping patterns of diversity is also well recognized. However, after 40 years of research, the importance of spatial variation in HP transfer intensity and effects remains poorly known, and thus we have ignored its potential in shaping patterns of diversity at local and global scales. Here, I develop a conceptual framework and summarize existing evidence for the ecological and evolutionary consequences of spatial variation in HP transfer interactions and outline future directions in this field.Conclusions: The drivers of variation in HP transfer discussed here illustrate the high potential for geographic variation in HP intensity and its effects, as well as in the evolutionary responses to HP receipt. So far, the study of pollinator-mediated plant-plant interactions has been almost entirely dominated by studies of pre-pollination interactions even though their outcomes can be influenced by plant-plant interactions that take place on the stigma. It is hence critical that we fully evaluate the consequences and context-dependency of HP transfer interactions in order to gain a more complete understanding of the role that plant-pollinator interactions play in generating and organizing plant biodiversity.
