  text: 'We introduce a general recursion for the probability of identity in state
    of two individuals sampled from a population subject to mutation, migration, and
    random drift in a two-dimensional continuum. The recursion allows for the interactions
    induced by density-dependent regulation of the population, which are inevitable
    in a continuous population. We give explicit series expansions for large neighbourhood
    size and for low mutation rates respectively and investigate the accuracy of the
    classical Malécot formula for these general models. When neighbourhood size is
    small, this formula does not give the identity even over large scales. However,
    for large neighbourhood size, it is an accurate approximation which summarises
    the local population structure in terms of three quantities: the effective dispersal
    rate, σe; the effective population density, ρe; and a local scale, κ, at which
    local interactions become significant. The results are illustrated by simulations.'
