Global biogeography and macroevolutionary patterns of angiosperm inflorescence types

The huge variety of inflorescences plays an important role in the reproductive success and diversification of flowering plants. However, the influence of climate on inflorescence diversity at macroecological and macroevolutionary scales remains poorly understood. In this study we map the global spatio-temporal pattern of inflorescence types and investigate the influence of climate on the spatiotemporal patterns of angiosperm inflorescence diversity. Our results reveal a clear latitudinal trend in inflorescence types, with indeterminate inflorescence frequency increasing away from the equator. Pollination mode composition and temperature variables are strong correlates of the geographic variation in inflorescence type frequency. We further reveal that lineages with determinate inflorescence have significantly higher net diversification rate than those with indeterminate inflorescence. The frequency of evolutionary transitions from indeterminate to determinate inflorescences consistently ..., , , # Global biogeography and macroevolutionary patterns of angiosperm inflorescence types

花序的丰富多样对于被子植物（Angiosperm）的生殖成功与物种分化至关重要。然而，在大生态与大演化尺度下，气候对花序多样性的影响仍未得到充分阐释。
本研究绘制了全球花序类型的时空分布格局，并探究了气候对被子植物花序多样性时空格局的影响。研究结果揭示了花序类型的显著纬度梯度规律：越远离赤道，无限花序（indeterminate inflorescence）的占比越高。传粉模式组成与温度变量是花序类型占比地理差异的重要驱动因子。本研究进一步发现，具有有限花序（determinate inflorescence）的支系，其净分化速率显著高于无限花序支系。从无限花序向有限花序演化的转换频率持续……，# 被子植物花序类型的全球生物地理与大演化格局
