This chapter considers the signal of local dispersal which sits inside maps of the locations of individuals, and introduces spatial statistics as measures of spatial structure. It shows how dispersal plays a fundamental part in local population dynamics. Dispersal is also shown to have important implications for the outcome of local spatial competition between two species, the dynamics of metapopulations, and the structure of multispecies communities. Local dispersal causes clumping, slows down changes in density, and affects the asymptotic state ultimately achieved by a population. When different species compete, dispersal over greater distances gives a species an advantage which can eliminate competitive coexistence which might otherwise occur. However, in the presence of spatial environmental heterogeneity, where too much dispersal can move offspring away from favourable parts of the environment, dispersal over intermediate distances can allow faster population growth than dispersal over either short or long distances.
