围栏条件下岩松鼠对核桃的贮藏
Hoarding of walnuts by David's rock squirrels (Sciurotamias davidianus)within enclosure
摘要
Abstract
A variety of animals store food to cope with temporally variable or unpredictable food supplies.We have little knowledge of the food hoarding behavior of David's rock squirrels (Sciurotamias davidianus), a species endemic to China and mainly distributed in the hilly temperate zone in northern China.We constructed semi-natural enclosures in the Donglingshan mountains area in which we investigated the squirrels' food hoarding behavior by providing them with tagged walnuts (Juglans regia).The results showed that David's rock squirrels exhibited both larder and scatter hoarding, and the latter seemed to be their preferred choice.Artificial pilferage of hoarded food items had no significant effect on the hoarding behavior of squirrels.Within the enclosures, squirrels tended to select certain sites to scatter hoard walnuts, and no walnuts were consumed at the location where they were provisioned.The possible factors affecting food hoarding of David's rock squirrels were discussed.关键词
