Abstract

We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 tree species. Within-plot species composition reflected both local environmental conditions (especially soil nutrients and hydrology) and geographical regions. A broader-scale view of species turnover was obtained by interpolating the relative tree species abundances over Amazonia into 47,441 0.1-degree grid cells. Two main dimensions of spatial change in tree species composition were identified. The first was a gradient between western Amazonia at the Andean forelands (with young geology and relatively nutrient-rich soils) and central-eastern Amazonia associated with the Guiana and Brazilian Shields (with more ancient geology and poor soils). The second gradient was between the wet forests of the northwest and the drier forests in southern Amazonia. Isolines linking cells of similar composition crossed major Amazonian rivers, suggesting that tree species distributions are not limited by rivers. Even though some areas of relatively sharp species turnover were identified, mostly the tree species composition changed gradually over large extents, which does not support delimiting clear discrete biogeographic regions within Amazonia.

摘要

我们描述了亚马逊森林中树种组成的地理变化，并展示了环境条件与物种更替之间的关联。我们的分析基于2023个森林清查样地（1公顷），这些样地提供了总共5188种树木的丰度数据。样地内的物种组成既反映了当地的环境条件（特别是土壤养分和水文状况），也反映了地理区域。通过将亚马逊地区相对的树种丰度插值到47441个0.1度的网格单元中，获得了更宏观尺度的物种更替视图。确定了树种组成空间变化的两个主要维度。第一个是安第斯前沿的亚马逊西部地区（地质年轻，土壤养分相对丰富）与与圭亚那和巴西盾相关的亚马逊中东部地区（地质更古老，土壤贫瘠）之间的梯度。第二个梯度是西北部的湿润森林与亚马逊南部较干燥森林之间的梯度。连接相似组成单元的等值线穿过了亚马逊的主要河流，这表明树种分布不受河流限制。尽管确定了一些物种更替相对明显的区域，但大多数情况下，树种组成在很大范围内是逐渐变化的，这并不支持在亚马逊地区划定明确的离散生物地理区域。
