热带山地树种的地上和地下策略受小规模氮供应的协调和驱动

地上和地下植物器官的策略是否如植物经济学谱系理论所预测的那样相互协调，这个问题仍在争论之中。我们旨在确定树木地上和地下功能性状变异的主要维度，并检验它们是否代表了热带安第斯森林土壤肥力梯度的适应谱系。我们测量了海拔 1000 米至 3000 米三个海拔高度上 52 个树种 433 棵树的叶片、茎和细根的功能性状，以及个体水平的土壤养分可用性。树种在性状空间的获取-保护轴上所处的位置与当地土壤氮（而非磷）的可用性密切相关。我们的研究结果表明，地上和地下植物的功能特征决定了共存树种可以在哪种土壤微生境中生长，这对于了解物种丰富的热带山地森林中的群落组合至关重要。在期刊博客上免费阅读本文的通俗摘要。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
