Population dynamics are determined by the demographic summation of individual reproductive success. Reproductive success (that is, fitness) is measured by the representation of descendants in the next generation. Many offspring disperse; therefore, the reproductive success of an individual cannot be known without determining the survivorship and reproductive output of their dispersing offspring. The investigator will continue a 28-year study of age, sex, social behavior, reproductive output, pattern of space-use, social organization, and survivorship over the lifetime of males and females from four colonies of yellow bellied marmots. In addition to collecting the basic demographic data necessary for continuity of this longitudinal study, Dr. Armitage will be analyzing data collected over the lifetime of the research. Many rodent populations require control. Control measures are ineffective if those animals that are killed or removed are quickly replaced by immigrants. Because yellow-bellied marmots frequently are agricultural pests, knowledge of the fate of dispersers will contribute to the preparation of effective control measures.

人口动态由人口统计学决定 个体繁殖成功的总和。 生殖 成功（也就是适应性）是通过以下表现来衡量的： 下一代的后代。 许多后代分散; 因此，一个个体的繁殖成功不能被 不确定生存和生殖 他们的子孙后代， 研究者将 继续一项长达28年的研究，研究对象是年龄、性别、社会行为， 生殖产出，空间利用模式，社会组织， 和生存在男性和女性的一生中， 四群黄腹土拨鼠 除了 收集必要的基本人口数据， 在这项纵向研究中，阿米蒂奇博士将分析 在研究的整个过程中收集的数据。 许多啮齿动物种群需要控制。 控制措施 如果那些被杀死或移走的动物 很快被移民取代。 因为黄腹土拨鼠 经常是农业害虫，知识的命运， 分散剂将有助于制备有效的 控制措施。
