| 4. | Description | Abstract | Morphological features of the East Siberian moose were studied in central and southern Yakutia, Siberia from 2005 to 2024. Body size was measured in 15 adult moose, hair colouration was described in 46, and horn shape in 78 individuals. According to morphometric characters, the East Siberian moose (Alces americanus pfizenmayeri) of Yakutia occupies a position intermediate between A. a. buturlini and A. a. cameloides and has morphological features characteristic of a subspecies. Four colour variations have been identified in the body colouration. The most common colouration is light brown (43.4%). In head colouration, 5 colour shades are detected, only brown colouration is common in both sexes. There are some sex differences in head colouration, females being coloured in lighter tones, vs males in darker tones. In males, 4 types of horn shape are identified: shovel-shaped horns with a divided shovel, with a narrow shovel and long ramifications, shovel-shaped with an undivided shovel and stag-shaped horns. Specimens with shovel-shaped antlers with a divided shovel are the most frequent (82.0%). A. a. buturlini has been recorded from central Yakutia. |

September, 2015), b – a female with last year’s calf with a dark brown hair color (photo from a camera trap by D. I. Tirsky. South Yakutia, Olekma river. September, 2018), c – adult male with a black body color (Central Yakutia, October 2013), d – adult male with a brownish-gray color (Central Yakutia, September 2014). (2MB) Fig. 2. Occurrence of color variations in the hair coat of the East Siberian moose in Yakutia (n = 46). (60KB) Fig. 3. Occurrence of color variations in the head coloration of the East Siberian moose in Yakutia (n = 41). (111KB) Fig. 4. Forms of antlers of the East Siberian moose of Yakutia: a – shovel-shaped antlers with a divided shovel, b – antlers with a narrow shovel with long processes, c – shovel-shaped antlers with an undivided shovel, d – deer-shaped antlers. Note: Typical deer-shaped antlers, for example, of the Ussuri moose, have a non-flattened shape and are round in cross-section, as is the antler shaft. The horn shown in Fig. 4d is similar in shape to the deer-shaped antlers presented in the literature (Boeskorov, 1998, 2001). (312KB) |
