Abstract:

Spatial memory of seed-caching is an important way to recover cached seeds for seed-hoarded animals. The current study was conducted to investigate whether there were differences between the recovering rates of buried seeds by David’s rock squirrels (Sciurotamias davidianus) and artificial control in shrubbery of Dongling Mountain of northwestern Beijing in October 2007. The results showed that: firstly, David’s rock squirrel preferred to cache seeds under shrubs with no obvious predilection on buried-substrate; secondly, no significant effects of buried-microhabitat and buried-substrate were observed on seeking of artificial buried seeds by David’s rock squirrel; thirdly, the recovering rates of David’s rock squirrels on artificial buried Juglans regia seeds were significantly different with that buried by themselves (Z=-2.499P=0.014), and more significant difference was observed on Juglans mandshurica seeds (Z=-6.557P<0.001).
