短尾猴栖息地的季节变化

本文阐述了短尾猴栖息地的季节变化。春季,主要利用海拔570-1600米的常绿阔叶林、常绿、落叶阔叶混交林和落叶阔叶林;夏季,限于海拔1000米以上的落叶阔叶林。秋季的栖息地,在海拔650-1200米常绿阔叶林和常绿、落叶阔叶混交林;冬季仅利用海拔600-900米的常绿阔叶林。此外还报道了短尾猴四季的食物组成。并对栖息地的变化原因,做了初步探讨。

SEASONAL HABITAT USED BY THIBETAN MONKEYS

Based on the data obtained during the period from 1973 to 1977, we made a survey of seasonal changes of Thibetan monkeys' habitats and their foods in the Huangshan moutains, from October, 1985 to July, 1986.The seasonal habitat changes of Thibetan monkeys are as follows: in spring they utilized evergreen broadleaved forest, deciduous and evergreen mixed broadleaved forest and deciduous broadleaved forest between 570m and 1,600m above sea level, while the habitat was limited to the deciduous broadleaved forest of over 1,000m asl in summer. The autumn habitat consisted of evergreen broadleaved forest, and deciduous and evergreen mixed broadleaved forest between 650m-1,200m asl, and in winter they only utilized evergreen broadleaved forest from 600m to 900m asl. Therefore, the utilized habitat range was the most abundant in spring and the most limited in winter.45 species of plants were found as the foods of Thibetan monkeys.these species were consisted of 26 evergreen trees (58%), 17 deciduous trees (38%), and 2 herbs (4 %), with seasonal changes, they utilized the different parts of plants. In spring, unfolding bud, soft leaf and soft stem were dominated, and in summer too. In autumn, seeds of Fagaceae and fruits were their main foods. In winter, both bark and stem of the trees were increased in their food list.
