ScienceDaily (Jan. 29, 2010) — New research suggests that animals
living at high latitudes grow better than their counterparts closer to  
the equator because higher-latitude vegetation is more nutritious. The

presents a novel explanation for Bergmann's Rule, the observation that  
animals tend to be bigger at higher latitudes.
