种内和种间竞争对花鼠分散贮藏的影响摘要2009年8－9月在黑龙江省带岭区东方红林场实验地新建的围栏内，研究种内和种间竞争对花鼠分散贮藏行为变化的影响，研究发现：（1）雌性个体的埋藏强度明显高于雄性个体；（2）种间竞争引起花鼠对红松种子分散贮藏比例的增加，而种内竞争不引起花鼠分散贮藏行为的显著变化；（3）种内竞争条件下，同性竞争和异性竞争均对花鼠分散贮藏行为无显著影响；（4）雄性个体在雄性个体竞争下，埋藏强度不变；而在雌性个体竞争下，埋藏强度增加；（5）雌性个体在雌性和雄性竞争条件下，花鼠分散贮藏行为无明显变化。关键词：围栏，红松种子，花鼠，竞争，分散贮藏EffectsofIntra-andInter-SpecificCompetitiononScatter-HoardingofChipunk(Eutamiassibiricus)ABSTRACTTostudytheeffectsofintra-specificandinter-specificcompetitiononscatter-hoardingofSiberianchipmunk(Eutamiassibiricus),aseriesofexperimentswerecarriedoutinDongfanghongForestDailingDistrictHeilong激angProvincefromAugusttoSeptember2009.Theresultsshowedthat:(1)Scatter-hoardingintensityofmaleandfemaleindividualsdifferedsignificantly,withfemalesscatter-hoardingmoreseeds;(2)Inter-specificcompetitionincreasedscatter-hoardingofSiberianchipmunk,however,nosignificanteffectwasfoundfromintra-specificcompetition;(3)Regardlessofthesexofcompetedindividuals,bothinter-andintra-sexualcompetitionsshowednosignificantinfluenceonscatter-hoardingofSiberianchipmunk;(4)Inter-sexualcompetitionincreasedscatter-hoardingofmaleindividuals;(5)Bothinter-andintra-sexualcompetitionsshowednosignificantinfluenceonscatter-hoardingoffemaleindividuals.KEYWORDS：Semi-naturalenclosure,Pinuskoraiensis,Eutamiassibiricus,Competition,Scatter-hoarding目录种内和种间竞争对花鼠分散贮藏的影响.................................................................................I摘要.........................................................................................................................................IABSTRACT...............................................................................................................................II目录.........................................................................................................................................III符号说明..................................................................................................................................IV第一章文献综述.......................................................................................................................51.1花鼠简介...............................................................................................................51.2国内外相关研究进展...........................................................................................51.3本实验研究的目的意义.......................................................................................6第二章试验部分.......................................................................................................................72.1研究方法...............................................................................................................72.1.1研究地概况................................................................................................72.1.2标记与释放................................................................................................72.1.3围栏设计....................................................................................................72.1.4实...
