Named for German biologist, Karl Bergmann (1814-1865), who observed the effect exclusively in endotherms, warm-blooded animals. We have since found similar trends in cold-blooded 'ecotherms', including marine invertebrates like copepods. So why?

Here I need to bring in the Allen rule as well, which modifies Bergmann's: cold temperatures tend to favor shorter limbs, but larger stature. Using the same number of cubes, you can see that shorter, thicker stacks have less surface area for their volume, which reduces heat flow.
