| measles metapopulation dynamics: a gravity model for epidemiological coupling and dynamics. | infectious diseases provide a particularly clear illustration of the spatiotemporal underpinnings of consumer-resource dynamics. the paradigm is provided by extremely contagious, acute, immunizing childhood infections. partially synchronized, unstable oscillations are punctuated by local extinctions. this, in turn, can result in spatial differentiation in the timing of epidemics and, depending on the nature of spatial contagion, may result in traveling waves. measles epidemics are one of a few s ... | 2004 | 15278849 |
