Exploring the Role of Skin Pigmentation in the Thermal Regulation of Polar Bears and Its Implications in the Development of Biomimetic Outdoor Apparel

A popular belief for why polar bears have black skin is to increase solar heat gain from solar radiation that penetrates through a translucent fur layer made of unpigmented hollow hair. To examine the relative importance of skin color on solar heat gain, we measured thermal gradients, heat flux, and...
