How does the structure of the white-tailed deer's winter coat aid in thermal regulation?
Answer
The individual hairs become hollow, creating pockets of trapped air for superior insulation.
The transition from the short, sleek summer coat to the winter covering involves significant structural modification, particularly in the hairs themselves. For colder climates, the deer replaces its warmer season coat with a much thicker, longer layer. Crucially, the individual hairs of this winter coat become hollow. These hollow shafts act as microscopic insulating tubes, trapping pockets of air close to the deer's body. This trapped air dramatically reduces heat loss to the surrounding frigid environment, providing the necessary insulation for survival in northern ranges where temperatures drop considerably.
