Allen’s rule states that__

#Unit 10. Ecological Principles
  1. Those species in colder, arctic environments have shorter ears than those in temperate or hot desert environments
  2. Individuals with greater mass have a smaller surface area to volume ratio, which helps to conserve heat

  3. Many organisms cope with heat stress by producing increased amounts of heat shock proteins (HSPs)

  4. among closely related endothermic (warm-blooded) vertebrates, those living in colder environments tend to have shorter appendages than those living in warmer environments
