Terrestrial ecosystems are changing in biodiversity, species composition and functional trait composition. To understand the underlying causes of these changes and predict the long‐term resilience of the ecosystem to withstand future disturbances, we can evaluate changes in diversity and composition from fossil pollen records. Although diversity can be well estimated from pollen in temperate ecosystems, this is less clear for the hyperdiverse tropics. Moreover, it remains unknown whether functional composition of plant assemblages can be accurately predicted from pollen assemblage composition. Here, we evaluate how community‐weighted mean (CWM) traits and diversity indices change along elevation.

现代花粉雨可预测植物性状组成的变化，但不能预测沿安第斯山脉至亚马逊海拔梯度的植物多样性

陆地生态系统的生物多样性，物种组成和功能性状组成正在发生变化。为了了解这些变化的根本原因并预测生态系统抵御未来干扰的长期复原力，我们可以从化石花粉记录中评估多样性和组成的变化。尽管从温带生态系统中的花粉可以很好地估计多样性，但对于高分热带地区而言，这还不清楚。此外，从花粉组合物组成中能否准确预测植物组合物的功能组成仍是未知的。在这里，我们评估了社区加权均值（CWM）特征和多样性指数如何随海拔变化。
