Figure 4. Examples of individual modal assignment to clusters when analysing simulated data sets with three Bayesian methods. Different symbols represent different clusters. Figures (a) to (d) show results from analyses of IBD-only data sets (i.e. *K* = 1), with the data set in the other figures containing a simulated barrier dissecting the study area approximately at 6°06′ (i.e. *K* = 2). (a) Assignments using the spatial model in baps 4·1·4, analysing simulated data with a density of 3 individuals unit area^{−1} and a dispersal of 2·0 units, slope of *b* = –0·014, optimal *K* = 3 (b) geneland, density 3, dispersal 2·0, *b* = –0·012, *K* = 4 (c) structure, density 0·5, dispersal 1·5, *b* = –0·079, Δ*K* = 4 (d) structure, density 0·5, dispersal 4·4, *b* = –0·014, ln(*X* |* K*) = 3 (e) baps and (f) geneland analysis , density 0·5, dispersal 6·0, *b* = –0·010, *K* = 2 (g) baps and (h) geneland analysis, density 0·5, dispersal 3·9, *b* = –0·021, optimal *K* = 4 (i) structure, density 0·5, dispersal 2·0, *b* = –0·073, Δ*K* = 2 (j) structure, density 0·5, dispersal 6·0, *b* = –0·010, ln(*X* |* K*) = 2.
