围栏条件下同域分布三种鼠对两种种子的贮藏行为差异
Seed-hoarding behaviours of three sympatric rodent species on two tree species under semi-natural enclosure conditions
摘要
Abstract
Seed-hoarding is believed to be an adaptive strategy for survival during periods of food shortage for many seedeating rodents.Sympatric rodents may evolve different hoarding strategies which may be beneficial to their coexistence.This study investigated hoarding behaviours of three sympatric rodent species (Chinese white-bellied rats,Niviventer confucianus,south China field mice,Apodemus draco,Gansu hamster,Cansumys canus) on seeds of two co-occurring trees (Chinese chestnut,Castanea mollissima and Oriental white oak,Quercus aliena) under enclosure conditions in Foping National Nature Reserve,Qinling China,during October-December 2014.Seeds of C.mollissima have higher protein and fat (hereafter high nutrition seeds),but fewer tannins than do seeds of Q.aliena (hereafter high tannin seeds).The results showed that,1) N.confucianus larder-hoarded C.mollissima seeds,A.draco mainly larder-hoarded Q.aliena seeds as well as scatter hoarded a few seeds of this species,whereas C.canus larder hoarded seeds of the two tree species only;2) N.confucianus and C.canus preferred to hoard the high nutrition seeds (C.mollissima),whereas A.draco tended to hoard the high tannin seeds (Q.aliena);3) All three rodent species preferred to eat the high nutrition seeds (C.mollissima),rather than the high tannin seeds (Q.aliena).These results suggest that sympatric rodent species have different hoarding strategies for seeds of co-occurring trees,and such differences are largely affected by seed traits.关键词
