Plant communities will change along environmental gradients, even in “azonal” vegetation such as wetlands. It is hypothesized that functional community composition of wetland vegetation changes along a natural gradient from dry low‐lying areas to wet high‐lying areas. We wanted to know how the functional groups that make up wetland plant communities change along such aridity and altitudinal gradients.

南非高原高原湿地植被植物功能成分的变化特征

植物群落将随着环境梯度的变化而变化，即使在诸如湿地之类的“共生”植被中。假设湿地植被的功能性群落组成会沿着自然梯度从干燥的低洼地区到湿润的高海拔地区变化。我们想知道组成湿地植物群落的功能群如何随着干旱和海拔梯度的变化而变化。
