Abstract:

In order to find out main factors influencing the feeding of golden monkey(Rhinopithecus roxellana)in Qianjiaping, Shennongjia Nature Reserve, summer and autumn food composition was investigated through quadrat survey and histological analysis of plant remains in feces. The analysis included nutritional components, relative abundance and relative density in the feces. The results showed that, in summer, food composition of Rhinopithecus roxellana was positively correlated to the relative abundance(r=0.656, P=0.000), water content(r=0.078, P=0.609), crude fat content(r=0.020, P=0.896)and the nitrogen-free extract content(r=0.238, P=0.115)of food plants, and negatively correlated to crude protein content(r=-0.113, P=0.459), crude fiber content(r=-0.144, P=0.347)and crude ash content(r=-0.156, P=0.305)of food plants; Food composition in autumn had positive correlation with the relative abundance(r=0.703, P=0.000), water content(r=0.258,P=0.176), crude fat content(r=0.291,P=0.125), crude protein content(r=0.537, P=0.003), crude fiber content (r=0.194, P=0.312)and crude ash content(r=0.308, P=0.104)of food plants, and negative correlation with the nitrogen-free extract content(r=-0.546, P=0.002)of food plants. Principal component analysis suggested that nitrogen-free extract(0.936), crude fiber(0.886)and crude ash(0.870)were the main affecting factors in summer, whereas rude fiber(0.968), crude protein(0.948)and food abundance(0.877)were the main factors in autumn.
