Losses in species richness and functional diversity of tree assemblages have often been observed in Neotropical fragmented landscapes, but the way in which tree phylogenetic diversity responds to forest insularization over decadal timescales remains unclear. Here, we examine how tree phylogenetic diversity and structure have responded to profound landscape alteration and subsequent non-random species losses within forest islands created within a vast hydroelectric reservoir.

隔离 26 年后，森林岛屿亚马逊树木组合的系统发育同质化

在新热带地区的破碎景观中经常观察到树木组合的物种丰富度和功能多样性的丧失，但树木系统发育多样性在十年时间尺度上对森林孤立化的反应方式仍不清楚。在这里，我们研究了树木的系统发育多样性和结构如何对巨大的水力发电库内产生的森林岛屿内的深刻景观变化和随后的非随机物种损失做出反应。
