The goal of this research was to see what happened when Bergmann's Rule collided with Rensch's Rule Sexual Size Dimorphism (SSD) and body size varied as a result of eco-geographical factors. In the woodland millipede genus Centrobolus, body size and SSD were associated with latitude, longitude, precipitation, and temperature. SSD and longitude (r=0.37, Z score=1.71, n=22, p=0.04), precipitation (r=0.29, Z score=1.28, n=22, p0.010), and temperature (r=0.34, Z score=1.49, n=22, p0.07) all had significant positive relationships. SSD and latitude had a significant relationship (r=-0.44, Z score=2.05, n=22, p=0.02). Larger females and greater SSD exist in warmer, wetter north-eastern settings, indicating eco-geographical variation in polygynandrous reproductive systems.
