食物源距离对中华姬鼠贮藏策略的影响
Effect of food source distance on hoarding strategy of Apodemus draco
摘要
Abstract
The effect of food source distance on hoarding strategy of South China field mice (Apodemus draco) was tested in a semi-natural enclosure,and two predictions based on the Rapidly Sequestering Hypothesis and Optimal Cache Spacing Model were examined:(1) Seeds would be scatter-hoarded near the three test sites respectively regardless of distance between nest and test sites;(2) With increasing of distance between cache site and nest,the proportion of larder-hoarded-seeds would decrease.In our study,eight South China field mice were selected and tested successively,three test sites were placed with 20 seeds respectively once a time.After 14 hours free movement of the mice,the fate of seeds was recorded.The seed fate was classified into three types:(1) eaten in nest;(2) eaten out nest;(3) larder-hoarded;(4)scatter-hoarded.The results showed that scatter-hoarding behavior is the main caching strategy of A.draco,and there was no significant difference in the number of seeds scatter-hoarded in the three test sites,supporting prediction 1.The proportions of seeds that were larder-hoarded decreased with the increase of distance between test site and the nest (1 m ∶6.25％;5 m∶ 1.88％;13 m∶ 1.25％),supporting prediction 2.Our results indicated that with the increased predation risk,A.draco tend to reduce the number of seeds eaten and cached.关键词
