Detailed explanation-1: -Mammals from colder climates generally have shorter ears and limbs to minimise heat loss. This is stated by: Q. Allen’s rule states that mammals from colder regions generally have ears and limbs to heat loss.

Detailed explanation-2: –Another example of Allen’s rule is the correlation between ear length and air temperature for hares (genus Lepus) and foxes. It states that the hares and foxes in the colder climate tend to have furry faces and short ears to conserve body heat.

Detailed explanation-3: -What is Allen’s rule? Allen’s rule is an ecogeographical rule which states that the limbs, ears and other appendages of animals living in colder climates are shorter than the animals of the same species living in warmer regions.

Detailed explanation-4: -Mammals from colder climates generally have shorter ear and limbs to minimize heat loss, this is called Allen’s Rule.

Detailed explanation-5: -Bergmann’s rule is an ecogeographical rule that states that within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions.
