植物功能性状可以预测植物群落的组成和生态系统的功能，因此被广泛应用于全球植被动态和陆地气候反馈模型。尽管如此，我们仍然缺乏对土地和气候如何影响植物性状的全面了解。先前对六个性状的全球分析观察到两个主要的变化轴：（1）器官和植物水平的大小变化和（2）平衡叶片持久性与植物生长潜力的叶经济学。这两个轴的正交性表明它们受到环境驱动因素的不同影响。我们发现，这些轴在超过20，000个物种的17个性状的全球数据集中持续存在。我们发现气候和土壤对性状变异的联合作用占主导地位。在大多数性状中也观察到其他独立的气候效应，而独立的土壤效应几乎只观察到经济性状。大小性状的变异与水分或能量限制相关的纬度梯度密切相关。相比之下，经济性状的变化更好地解释了气候与土壤肥力的相互作用。这些发现有可能提高我们对生物多样性模式的理解，并预测气候变化对地球化学循环的影响。作者调查了大尺度的气候和土壤特性，与植物功能性状的主轴共变。他们发现，植物大小的变化归因于水分或能量限制的纬度梯度，而叶经济性状的变化归因于气候和土壤肥力，包括它们的相互作用。
Plant functional traits can predict community assembly and ecosystem functioning and are thus widely used in global models of vegetation dynamics and land–climate feedbacks. Still, we lack a global understanding of how land and climate affect plant traits. A previous global analysis of six traits observed two main axes of variation: (1) size variation at the organ and plant level and (2) leaf economics balancing leaf persistence against plant growth potential. The orthogonality of these two axes suggests they are differently influenced by environmental drivers. We find that these axes persist in a global dataset of 17 traits across more than 20,000 species. We find a dominant joint effect of climate and soil on trait variation. Additional independent climate effects are also observed across most traits, whereas independent soil effects are almost exclusively observed for economics traits. Variation in size traits correlates well with a latitudinal gradient related to water or energy limitation. In contrast, variation in economics traits is better explained by interactions of climate with soil fertility. These findings have the potential to improve our understanding of biodiversity patterns and our predictions of climate change impacts on biogeochemical cycles. The authors investigate the broad-scale climatological and soil properties that co-vary with major axes of plant functional traits. They find that variation in plant size is attributed to latitudinal gradients in water or energy limitation, while variation in leaf economics traits is attributed to both climate and soil fertility including their interaction.
