As an undergraduate student, Emily Habinck, noticed that soil affected leaf color. Where there are more nutrients, the leaves tend to be yellow, but where the soil has less nutrients the leafs tend to be red.

While Habinck was at work on the project, William Hoch, a plant physiologist at Montana State University, wrote a paper suggesting an additional link between the red-leaf pigment anthocyanin and autumn sunlight.

I always thought that the leaf color had to do with the species of tree. Learn something new everyday! For more information, be sure to hop over to National Geographic!
