The hair coat and hair microstructure of an adult male Hydropotes inermis from the Primorsky Krai of Russia were studied for the first time by light and scanning electron microscopy. Lack of abundant underfur, sparse hair, and a weak layering are characteristic of the species, which inhabits the temperate monsoon and tropical zones and does not need an efficient thermal protection. An alveolar and lattice medulla of the hair is similar to that of other deer, is well developed, and increases the heat-protective properties of the hair because seasonal and daily fluctuations in temperature and humidity can be significant. The cuticle pattern is similar to that of the deer tribes Alceini and Capreolini. The hair thickness and length are substantial on the back, sides, and thighs, and the coat thus provides reliable protection from mechanical damage when the water deer moves through thickets of bushes and grasses along riverbanks and swamps in its habitats. A knotty nature of hairs protects the skin from sharp outgrowths of aquatic and marsh plants. [ABSTRACT FROM AUTHOR] |
