Carl Bergmann

Carl Bergmann was a 19th-century German biologist known for his work in ecology and animal morphology. He is best known for formulating Bergmann's Rule, which states that animals in colder climates tend to be larger than those in warmer regions. This phenomenon relates to body size and temperature regulation, where larger bodies conserve heat more effectively. Bergmann’s contributions helped shape our understanding of how environmental factors influence the physical characteristics of species, aiding in the study of biodiversity and adaptation in various ecosystems. His work has implications in fields such as ecology, evolution, and climate studies.
