In marine systems, adult populations confined to isolated habitat patches can be connected by larval dispersal. Source–sink theory provides effective tools to quantify the effect of specific habitat patches on the dynamics of connected populations. In this paper, we construct the next-generation matrix for a marine metapopulation and demonstrate how it can be used to calculate the source–sink dynamics of habitat patches. We investigate the effect of environmental variables on the source–sink dynamics and demonstrate how the next-generation matrix can provide useful biological insight into transient as well as asymptotic dynamics of the model.

计算海洋复合种群源-汇动力学的下一代方法

在海洋系统中，被限制在孤立栖息地斑块中的成虫种群可以通过幼虫的扩散来连接。源汇理论提供了有效的工具来量化特定栖息地斑块对相关种群动态的影响。在本文中，我们为海洋复合种群构建了下一代矩阵，并展示了如何使用它来计算栖息地斑块的源汇动态。我们研究了环境变量对源汇动力学的影响，并展示了下一代矩阵如何为模型的瞬态和渐近动力学提供有用的生物学洞察力。
