Question:
Is there a trend with the size of plant leaves and the environment they are found such as amount of sunlight? What variables are involved?


Replies:
Usually plants/trees have a particular, given range of leaf size for a particular species, so there would be an expected mean/average, and minimum and maximum values for leaf blade length, width, length/width ratio (related to leaf shape), and leaf area for the particular species, but also some variation depending upon climate, soil, age, and disturbance.

Here is an example article about variation in leaf size in response to increased sunlight, i.e., canopy gaps:
