Dynamics of Recruitment-Subsidized Populations

这项调查涉及招募的动态- 受补贴的人口，即增加 新的个体基本上或完全与当地的 生殖 这包括当地的底栖生物种群 有浮游幼虫和种类的生物（许多海洋鱼类） 其中随机变化使得种群补充 关系，如果有的话，无法察觉。这种人口统计学 人口最适合通过写作招募来建模 作为外部“补贴”。 种群的动态是 由通过后过滤的募集信号确定， 招募生活史卡斯韦尔博士将调查四个 模型（密度独立人口模型、密度依赖 人口模型，集合种群模型， 亚种群和多物种群落模型）， 补贴人口。这些模型将提供基本的 对受补贴人口动态的理论洞察。 前两项还将为实证人口统计学提供工具， 分析这些人群。

This investigation addresses the dynamics of recruitment- subsidized populations, i.e. populations in which the addition of new individuals is largely or completely uncoupled from local reproduction. This includes local populations of benthic organisms with planktonic larvae and species (many marine fish) in which stochastic variation renders stock-recruitment relations, if any, undetectable. The demography of such populations is most appropriately modelled by writing recruitment as a external "subsidy". The dynamics of the population are determined by the recruitment signal filtered through the post- recruitment life history. Dr. Caswell will investigate four models (density-independent demographic models, density-dependent demographic models, metapopulation models for coupled subpopulations, and multi-species community models) for subsidized populations. These models will provide fundamental theoretical insight into the dynamics of subsidized populations. The first two will also provide tools for empirical demographic analysis of such populations.
