Abstract

An analysis of over 1 million old-growth tropical forest trees reveals that ∼2.2% of species comprise 50% of the individuals in Africa, Amazonia, and Southeast Asia, suggesting that the ecological mechanisms underpinning tree community assembly are ubiquitous across the tropics.

摘要

对超过 100 万棵古老热带森林树木的分析表明，在非洲、亚马逊和东南亚，约 2.2%的物种构成了 50%的个体，这表明支撑树木群落组装的生态机制在整个热带地区普遍存在。
