摘要
在佛坪自然保护区对秦岭羚牛的食性研究中 ,记录到羚牛采食 1 61种植物 ,其中草本占 3 2 9% ,木本占 62 7% ,苔藓植物和蕨类植物占 4 4 %。羚牛的食物呈季节性变化 ,它采食的植物种类在春季、夏季比秋季、冬季多。羚牛是广食性的植食动物 ,但它对所采食植物的部位具有一定的选择性 ,主要以采食植物的嫩枝叶为主 ,同时还有啃食树皮的习性。野外见到羚牛以直接饮水或舔雪的方式来补充对水份的需求。
Golden takins foraged on a wide variety of plants, 161 plant species had been recorded as food items in Foping Nature Reserve which locates in the middle range of south slope Qinling Mountain. Takins were primarily browser, shrubs and trees were accounted for 62.7% of the food items, herbs 329%, mosses and ferns 44% respectively. Takins mainly fed on twigs, shoots, stems and leaves of plants, but they had to feed on barks in the seasons of food shortage. Seasonal deference in food items could be detected in the study area. In the field we observed that takins licked snows or drank water directly to meet their water requirement.
