Pollen limitation occurs widely and has an important effect on flowering plants. The East Himalaya-Hengduan Mountains region is a global biodiversity hotspot. However, to our knowledge, no study has synthetically assessed the degree of pollen limitation in this area. The present study aims to reveal the degree of pollen limitation for the flowering plants growing on East Himalaya-Hengduan Mountains and to test whether the reproductive features or the elevation is closely correlated with the degree of pollen limitation in this area. We complied data from 76 studies, which included 96 species and 108 independent data records. We found that the flowering plants in this area undergo severe pollen limitation [overall Hedges’ d = 2.004, with a 95% confidence interval (1.3264, 2.6743)] that is much higher than that of the flowering plants growing in many other regions around the world. The degree of pollen limitation was tested to determine the correlation with the capacity for autonomous self-reproduction and with the pollination pattern (generalized vs. specialized pollination) of plants. In addition, we found a clear relationship between elevation and the degree of pollen limitation, which indicates that plants might undergo more severe pollen limitation in relatively high places. This paper is the first to address the severe pollen limitation of the flowering plants growing in East Himalaya-Hengduan Mountains region. Moreover, we reveal the positive correlation between elevation and the degree of pollen limitation.

荟萃分析显示东喜马拉雅山-横断山区的开花植物存在严重的花粉限制

花粉限制普遍发生,并且对开花植物具有重要影响。东喜马拉雅山-横断山脉地区是全球生物多样性热点。然而,据我们所知,尚无研究综合评估该地区花粉限制的程度。本研究旨在揭示东喜马拉雅-横断山区生长的开花植物的花粉限制程度,并测试该地区的繁殖特征或海拔高度与花粉限制程度是否密切相关。我们收集了来自76个研究的数据,其中包括96种和108个独立的数据记录。我们发现该地区的开花植物受到严重的花粉限制[总体树篱d = 2.004,置信区间为95%(1.3264,2。6743)],远高于世界许多其他地区的开花植物。测试了花粉限制的程度,以确定与植物自主自我繁殖的能力和植物的授粉模式(一般授粉与专业授粉)的相关性。此外,我们发现海拔高度与花粉限制度之间存在明显的关系,这表明植物在相对较高的地方可能经历更严重的花粉限制。本文是第一个解决东喜马拉雅山-横断山脉地区开花植物严重花粉限制的问题。此外,我们揭示了海拔与花粉限制程度之间的正相关。测试了花粉限制的程度,以确定与植物自主自我繁殖的能力和植物的授粉模式(一般授粉与专业授粉)的相关性。此外,我们发现海拔高度与花粉限制度之间存在明显的关系,这表明植物在相对较高的地方可能经历更严重的花粉限制。本文是第一个解决东喜马拉雅山-横断山脉地区开花植物严重花粉限制的问题。此外,我们揭示了海拔与花粉限制程度之间的正相关。测试了花粉限制的程度,以确定与植物自主自我繁殖的能力和植物的授粉模式(一般授粉与专业授粉)的相关性。此外,我们发现海拔高度与花粉限制度之间存在明显的关系,这表明植物在相对较高的地方可能经历更严重的花粉限制。本文是第一个解决东喜马拉雅山-横断山脉地区开花植物严重花粉限制的问题。此外,我们揭示了海拔与花粉限制程度之间的正相关。我们发现海拔高度与花粉限制度之间存在明确的关系,这表明植物在相对较高的地方可能经历更严重的花粉限制。本文是第一个解决东喜马拉雅山-横断山脉地区开花植物严重花粉限制的问题。此外,我们揭示了海拔与花粉限制程度之间的正相关。我们发现海拔高度与花粉限制度之间存在明确的关系,这表明植物在相对较高的地方可能经历更严重的花粉限制。本文是第一个解决东喜马拉雅山-横断山脉地区开花植物严重花粉限制的问题。此外,我们揭示了海拔与花粉限制程度之间的正相关。
