Feeding Habits of Badger in Autumn in Zhangguangcai Mountains
In order to understand the food composition of the badger(Meles meles)in autumn in Zhangguangcai Mountains,the fecal analysis was used to analyze the feeding habits of badgers in autumn.The results showed that there were a total of 10 kinds of badger food composition in autumn.Actinidia kolomikta(frequency of occurrence:75.51%;biomass ratio:76.85%),Pheretima(frequency of occurrence:97.96%;biomass ratio:10.01%),Zea mays(frequency of occurrence:32.65%;biomass ratio:7.22%),and insects(frequency of occurrence:89.80%;biomass ratio:1.51%)were the main diet of badgers in autumn in Zhangguangcai Mountains.Among the plant foods,Actinidia kolomikta and Zea mays were mature in large quantities in the autumn with a large yield.This might be the reason why these two foods made up a larger portion.From the perspective of frequency and biomass ratio of carnivorous foods,Pheretima occupied the dominant position of badger carnivorous foods,indicating that in autumn,Pheretima were easier to obtain than the other carnivorous foods.With these results,the Shannon-Wiener diversity index H'was 0.887,the evenness index E was 0.385,and standard Levins niche width index Bsta was 0.072,respectively,which indicates that badgers are opportunistic wide-eaters,and their food composition changes correspondingly with seasonal and other environmental factors.
