Bergmann's Rule

Bergmann's Rule is a biological principle stating that within a species, individuals in colder climates tend to be larger than those in warmer areas. The larger body size helps retain heat, making it easier to survive in chilly environments. Conversely, smaller bodies are more efficient in warmer climates, as they can lose heat more easily. This rule highlights how animals adapt to their environments in terms of size, which can impact their survival and reproduction. Essentially, body size is influenced by climate conditions to optimize temperature regulation.
