Genetics of colonizing Litoditis marina. MtDNA haplotype composition of the developing L. marina populations during the course of the experiment for each patch separately. A1 A3 refer to the three patches in site A that were incubated amidst permanent Fucus stands, while B1 B4 refer to the four patches in site B that were incubated in the absence of permanent algal stands. Distance between algal deposits within a site averaged 2 m, while site A and B were approximately 2 km apart. A-W represent different haplotypes. Note the late colonization and the low number of haplotypes of patches B2-B4, and the dominance of different haplotypes among B1-B4 (Figure from [48]).
