达乌尔黄鼠室内繁殖的可能影响因素

繁殖活动是种群延续的基础，也是种群生态学和行为生态学研究的一个重要部分，动物是否能够繁殖成功将影响到整个种群的生存和灭亡。按照现代生活史原理，繁殖成功率决定于环境因素、性成熟的年龄、繁殖次数、婚配制度、个体所处的社会等级地位等。物种为了提高其自身的适合度，会根据环境和自身状况等条件来调整繁殖投入，进而影响其繁殖成功率。达乌尔黄鼠（Spermophilus daurious）广泛分布于我国西北、东北和华北地区，具有冬眠的生物学特性。很多生物学工作者和医学工作者都以其为模型动物，进行研究。为了使达乌尔黄鼠在实验室内繁殖成功，并将其实验动物化，结合国内外相关文献和实验室内环境，分析了可能会影响达乌尔黄鼠室内繁殖的因素并提出适当的对策，以便为该物种的实验室繁殖提供参考。

Some Factors Influence Reproduction of Daurian Ground Squirrel(Spermophilus daurious) in Laboratory

Reproduction activities are the basis of population sustaining,also an important research area in population ecology and behavior ecology.The reproduction ability of animals determines the survival or extinction of the species.According to the modern life history principle,reproductive success determined by environmental factors,the age of sexual maturity,frequency of reproduction,mating system and the social class status of individual.In order to improve their fitness,species could adjust their reproductiv...
