Species diversity generally increases in the tropics but testing theories that explain this phenomenon is challenging. Here we use body size to quantify niches in ecological communities and explore how species diversify towards the equator.

We thank Kate Thibault at NEON for helping us to compile and interpret the small mammal data. We thank S. Record's Biological Exploration course at Bryn Mawr College for their feedback as we piloted an early version of this exercise. NSF grant 1550770, 1550765, and 155075 awarded to S. Record, P. Zarnetske, and B. Baiser, respectively.
