Abstract
在新疆且末县境内研究了塔里木马鹿(Cervus elaphus yarkandensis)的食性和采食地选择.野外直接观察结合粪便显微分析表明,该亚种共采食15种植物,冬季采食13种植物,夏季采食9种.冬季由于高质量食物缺乏,马鹿采食更多的植物种类.无论在冬季还是夏季,芦苇(Phragmites communis)、胀果甘草(Glycyrrhiza inflata)和胡杨(Populus diversifolia)均为经常采食的3种植物.其中,芦苇在研究区资源最为丰富,是塔里木马鹿最主要的食物.对圈养条件下食物选择频次的观察表明,胡杨是塔里木马鹿最喜食的植物,但在研究区资源有限.研究区的采食地按植被特征可划分为5种类型:(1)芦苇-多枝柽柳(Tamarix ramosissima)型;(2)多枝柽柳-盐穗木(Halostachys caspica)型;(3)多枝柽柳-芦苇型;(4)胡杨-芦苇型;(5)烧迹地.其中,芦苇-多枝柽柳型(芦苇草甸和芦苇沼泽)是塔里木马鹿最喜好的采食地类型.浓密的芦苇有助于马鹿躲避天敌,在夏季为马鹿提供遮荫场所.这一栖息地类型能够同时为马鹿提供食物、水源和隐蔽场所
