摘要

人们普遍认为,大尺度的地形变化会影响树木多样性的分布,而小尺度地形的影响却很少被认识到,但也同样重要。在高度多样化的亚马逊森林中,物种分布对小至22米的海拔差异反应强烈,我们评估了小尺度地形变化如何影响树木的人口统计学和多样性。为了形成地形结构的物种分布,物种应该在与其相关的地形栖息地中生长和生存(表现)更好(最佳家园假设),并且它们应该比在该栖息地中发现但不强烈聚集的其他物种表现更好(居民优势假设)。在这里,我们利用25公顷Amacayacu森林动态样地3种地形生境(山谷、斜坡和山脊)中79,911棵树(352种)的生长和死亡率数据来检验这些人口统计学假设。尽管海拔变化不大,但不同地形生境的树木生长和死亡率在群落水平上存在显著差异:生长在土壤湿度较高的山谷中的树木的生长和死亡率明显高于生长在斜坡和山脊上的树木。然而,树木的生长率不依赖于物种的栖息地关系,死亡率的变化与物种的栖息地关系不一致。我们的研究结果在一定程度上支持了山谷相关物种在其栖息地(山谷)生长得比其他地方最好的假设,与斜坡相关物种或通才物种(外来物种)相比,山谷相关物种的死亡率更低。对于斜坡和山脊相关的物种,我们的结果在群落水平上不支持这些假设。物种特异性分析显示,在群落水平上分析的352种物种中,有73种支持这两种假设。合成。我们的研究结果表明,即使海拔的微小差异也会导致资源获取的生物学意义上的变化,从而转化为树木生长和生存的显着差异。然而,资源获取不能完全解释我们观察到的地形驱动的人口变化模式。虽然某些物种在特定栖息地可能仍然表现出家园和居住优势,即使群落水平的平均值部分反映了这种模式,但在群落水平上观察到的模式可能是由其他假设驱动的。

期刊介绍: Journal of Ecology publishes original research papers on all aspects of the ecology of plants (including algae), in both aquatic and terrestrial ecosystems. We do not publish papers concerned solely with cultivated plants and agricultural ecosystems. Studies of plant communities, populations or individual species are accepted, as well as studies of the interactions between plants and animals, fungi or bacteria, providing they focus on the ecology of the plants. We aim to bring important work using any ecological approach (including molecular techniques) to a wide international audience and therefore only publish papers with strong and ecological messages that advance our understanding of ecological principles.
