青藏高原及其南界横断山脉地区是世界生物多样性的热点地区之一，有数百座大山，气候变化和生境异质性的多样性影响着植物适应性的进化。本文收集整理了近年来动物传粉植物生殖生物学的研究资料，并对近年来动物传粉植物生殖生物学的研究进展进行了综述。在此基础上，构建了该地区植物-传粉者相互作用网络，结果表明：该地区传粉者以蜜蜂为主，其次是蛾、蝶、蝇，蝙蝠和鸟类较少;传粉者相互作用网络的构建是植物-传粉者相互作用网络的一个重要组成部分气候（寒冷、多雨或多风）影响传粉者的活动，有性生殖似乎受到花粉的限制，但现有的研究表明，花粉限制的确切模式仍在争论中。自交亲和性可能是一种解决办法，也可能是花粉限制的结果。此外，植物的有性系统可以被看作是一个完整的模块，以对抗花粉限制。随着系统发育关系的建立，在这些山区，不同的属都经历了快速辐射。进一步研究同源生殖系统的进化转变进一步的研究将有助于利用先进的新技术，研究普通园林下的表型选择，并考虑植物与食花动物之间相互作用的化学生态学，特别是花粉命运。
Having hundreds of big mountains,the Qinghai-Tibetan Plateau and its southern boundary,the Hengduan Mountains Region,represent one of the world's biodiversity hotspots.In the so-called "Third Pole of the earth",diverse effects of climate change and habitat heterogeneity could have driven the evolution of plant adaptive strategies.In this review,we collected and compiled recent sources of reproductive biology in animal-pollinated plants,stressing the questions that need further attention,including pollination system,pollen limitation,self-compatibility,and sexual system.We constructed plant-pollinator interaction networks based on the case studies from this region,showing that the majority of pollinators were bees,moths,butterflies,and flies were also important,and bats and birds were rare.As the unpredictable (cold,rainy or windy) weather affects pollinator activities,sexual reproduction seemed to be pollen limited,but available studies show that the exact pattern of pollen limitation is still under debate.Self-compatibility could be either a solution,or a result from pollen limitation.Moreover,plant sexual systems can be regarded as an integrated module that counters pollen limitation.As phylogenetic relationships were constructed,diverse genera experienced rapid radiation were revealed in these mountainous areas.Further studies of evolutionary transitions in reproductive systems of congeners will unveil potential factors shaping the general pattern of adaptive strategies in animal-pollinated plants.Further studies will be beneficial in using advanced new techniques,examining phenotypic selection under common gardens,and considering chemical ecology in interactions between plants and florivores,particularly in pollen fate.
