Most models of spatially structured populations have the same basic format. The population is assumed to be
subdivided
into
demes
, which one can think of as ‘islands’ of population. The demes sit at the vertices of a graph and interaction between the subpopulations in different demes is through migration (or more accurately exchange) of individuals along the edges of the graph. The most elementary example is Wright’s island model. This is how he introduced it in (Wright (1943))
