| 摘 要： | 2008年11-12月和2009年4-5月对贺兰山野化牦牛的冬季和春季食性进行了分析,在其分布的哈拉乌沟收集冬季粪样500 g,春季粪样498 g,利用粪便显微分析法分析贺兰山牦牛取食植物的种类组成和比例,结果表明,冬季牦牛取食11科20种(属)植物,主要取食禾本科(59.10%)和菊科(26.05%)植物,其中针茅(35.86%)、冷蒿(23.96%)、冰草(8.28%)、莎草(7.60%)、虎尾草(6.81%)、芦苇(6.58%)构成了冬季食物总量的89.09%,为冬季主要食物。春季取食植物11科21种(属)植物,主要取食禾本科(52.76%)和莎草科(18.80%)植物,其中针茅(22.72%)、莎草(18.80%)、冰草(13.23%)、狗尾草(9.93%)、唐松草(6.46%)、冷蒿(6.31%)占春季食物总量的77.45%,为春季主要食物。此外,冬春季均取食一定量的毛茛科和豆科植物。冬春季针茅都是贺兰山野化牦牛的大宗食物。冬季食物生态位宽度低于春季,而Shannon-Wiener指数和Pielou均匀度指数均高于春季。 |

| Abstract: | Feral yak were introduced into the Helan Mountains on the border between Ningxia Hui and Inner Mongolia Autonomous Regions,China,by the Buddhist monks of Tibet about two hundred years ago.The feral yak population was estimated to be around 200 individuals at present.The plant species composition of the diet of feral yak was studied in order to better understand seasonal variation from November to December 2008 and from April to May 2009.We collected 5-10 g fecal pellets of feral yak from each dung piles in ... |
| Keywords: | feral yak diet composition fecal samples Helan Mountains |
