Mast seeding is one of the most intriguing reproductive traits in nature. Despite its potential drawbacks in terms of fitness, the widespread existence of this phenomenon suggests that it should have evolutionary advantages under certain circumstances. Using a global dataset of seed production time series for 219 plant species from all of the continents, we tested whether masting behaviour appears predominantly in species with low foliar nitrogen and phosphorus concentrations when controlling for local climate and productivity. Here, we show that masting intensity is higher in species with low foliar N and P concentrations, and especially in those with imbalanced N/P ratios, and that the evolutionary history of masting behaviour has been linked to that of nutrient economy. Our results support the hypothesis that masting is stronger in species growing under limiting conditions and suggest that this reproductive behaviour might have evolved as an adaptation to nutrient limitations and imbalances.

营养缺乏作为肥大播种的选择压力。

桅杆播种是自然界中最有趣的生殖特征之一。尽管它在适应度方面存在潜在缺陷，但这种现象的普遍存在表明它在某些情况下应该具有进化优势。使用来自所有大陆的 219 种植物物种的种子生产时间序列的全球数据集，我们测试了在控制当地气候和生产力时，肥大行为是否主要出现在叶面氮和磷浓度低的物种中。在这里，我们表明，在叶面 N 和 P 浓度较低的物种中，特别是在 N/P 比例不平衡的物种中，肥大强度较高，并且肥大行为的进化史与养分经济的进化史有关。
