英文摘要
Total 20 species of mammals were recorded from the Southern Cross-Island Highway in Yushan National Park. They belonged to Artiodactyla, Carnivora, Lagomorpha, Pholidota, Rodentia, Rodentia, Primates, and Insectivora. Among these 7 orders, Rodentia contains with the highest species ratio (8 species), followed by Artiodactyla. Endemic species were Mogera insularia, Soriculus fumidus, Macaca cyclopsis, Rattus culturatus, Apodemus semotus, and endemic subspecies were Lepus sinensis, Cervus unicolor, and Capricornis swinhoei. Based on the total recorded mammalisan species in Taiwan, more than 1/3 of species could be found in the Southern Cross-island Highway. White faced flying squirrels was the animal with the highest recorded frequency, and followed by formosan giant flying squirrels. According to different sections of the Highway, we saw 17 species near Tianchi, and 16 species from the YaKo Forest Road. In this study, only formosan serows and monkeys appeared in the areas where were more than 2000m in elevation. Most of animals along the Road were very difficult to be spotted, except flying squirrels, monkeys and formosan weasels.
