植物功能性状被广泛用于量化和预测气候变化对植被的影响。然而，高的种内性状变异可以偏置的平均值时，很少的测量是可用的。在这里，我们确定了广泛分布的亚热带松树在高度异质性的环境梯度的个体叶性状变异和协变的程度。我们证明了性状变异的影响，通过评估数据的可用性和变异性在松属物种的特征。
Plant functional traits are broadly used to quantify and predict impacts of climate change on vegetation. However, high intraspecific trait variation can bias mean values when few measurements are available. Here, we determine the extent of individual leaf trait variation and covariation across a highly heterogeneous environmental gradient for a widely distributed subtropical pine. We demonstrate the implications of trait variation for characterising species by assessing data availability and variability across the Pinus genus.
