Theory and applications of metapopulations

元人口是“人口的人口”，不同的地方由个体（人类或动物）在他们之间的运动联系在一起。元种群在生态学中用于描述动物在地理区域之间的移动和这些区域内种群的动态，在流行病学中用于描述旅行个体携带的传染性病原体的时空传播。例如，我用这个框架来描述传染病的全球传播，比如以全球航空运输网络为渠道的H1N1流感大流行。

Metapopulations are "populations of populations", with different places linked by the movement of individuals (humans or animals) between them. Metapopulations are used in ecology to describe movemement of animals between geographical regions and the dynamics of populations within those regions, and in epidemiology to describe the spatio-temporal spread of infectious pathogens carried by travelling individuals. I have for instance used this framework to describe the global spread of infections such as pandemic H1N1 Influenza using the global air transportation network as a conduit.
