中国新疆马鹿亚种头骨形态的地理变化
Geographical Variations of Skull Morphology in Red Deer (Cervus elaphus) in Xinjiang, China
摘要
Abstract
There are 3 subspecies of red deer in Xinjiang. The data of skull morphology on Cervus elaphus yarkandensis, Cervus elaphus songaricus, Cervus elaphus sibiricus were reported in this paper, which involved the measurement and comparison of skull variables of the 3 subspecies. Measured variables include the greatest length of the cranium, facial length, greatest length of the nasals, median frontal length, greatest inner width of infraorbital gland fossa, condylobasal length: aboral border of the occipital condyles-Prosthion, Graetest palatal breadth, premolare-prosthion length, zygomatic breadth, aboral height of the coronoid process-gonion ventrale-Coronion, aboral height of the vertical ramus: gonion ventrale-highest point of the condyle process, diastema height, Height of the mandible in front of P2, height of mandible behind M3. All variables measured were compared respectively between the 3 subspecies. The results showed that: 1) The deer from the Altai tended to have greater length and height of skull and smaller width than that from the Tarim. 2) Skulls of the Tianshan were intermediate between Tarim and Altai, but there tended to be no significant difference. 3) The skull morphological measurements of the Ahai and Tianshan subspecies were close to each other, and the Tarim sample was located rather distant from the former two. The variations of the skull morphological characters of red deer in Xinjiang are caused mainly by habitat and climatic differences of these subspecies. Altai and Tianshan subspecies inhabit in the coniferous forests with a cold climate, whereas that of the Tarim inhabit the riparian poplar forests along the river in desert region, which become very hot in summer. The morphological similarities between red deer from the Altai and Tianshan may reflect similarities in habitats, while the unique morphological characteristics of the Tarim red deer may reflect adaptations to a desert climate. Therefore, the Tarim subspecies is unique and should be protected.关键词
