Covariation in plant functional traits and soil fertility within two species-rich forests.

The distribution of plant species along environmental gradients is expected to be predictable based on organismal function. Plant functional trait research has shown that trait values generally vary predictably along broad-scale climatic and soil gradients. This work has also demonstrated that at an...

Plant functional trait research has shown that trait values generally vary predictably along broad-scale climatic and soil gradients.
