抄録

Recently, lattice models of population dynamics have been developed, in which sites are arranged regularly and each site may be occupied by an individual or a local population. Lattice models show that self-organizing heterogeneous spatial patterns often cause dynamics different from traditional population dynamics models without spatial structure. However, due to difficulty with mathematical analysis, most lattice models have been analysed only by computer simulations. Pair approximation is a useful technique for analysis of lattice models because it can predict the population dynamics fairly accurately even when mean-field approximation (which neglects spatial structure) gives qualitatively poor results.
