The study looked at how different types of plants change as you go up a mountain in Baihua Mountain Reserve, China. They found that the diversity of plant functions peaked in the middle of the mountain. The diversity was linked to factors like elevation, slope, and how thick the litter on the ground was. The study showed that the environment plays a big role in shaping the variety of plant functions. Overall, the study found that certain ways of measuring plant diversity were better at showing these patterns than others.
