提出了一个模型，用于联合分析标记-再捕获数据和阶段或年龄结构数据，允许在标准方法可能不可靠的情况下估计人口丰度，出生率和迁移率。该模型假设出生率遵循连续分布，并且迁移可以用一个简单的马尔可夫过程来描述。该模型的应用使用了圣劳伦斯湾灰海豹（Halichoerus grypus）幼崽生产的标记-再捕获和阶段结构数据，并得出1989年和1990年分别生产9800和10500只幼崽的估计。
A model is presented for the joint analysis of mark-recapture data and stage- or age-structured data that allows the population abundance, birth rates, and migration rates to be estimated in situations where standard methods may be unreliable. The model assumes that birth rates follow a continuous distribution and that migration can be described by a simple Markov process. Application of the model is illustrated using mark-recapture and stage-structured data for grey seal (Halichoerus grypus) pup production in the Gulf of St. Lawrence and resulted in estimates of 9800 and 10 500 pups produced in 1989 and 1990, respectively.
