Nevertheless, species ﬂocks. It would thus be difﬁcult to compare more than other methods, molecular markers have the biodiversity of 300 closely related cichlid species shown that there is often little discontinuity between from Lake Victoria with that of 300 divergent species genetic population differentiation and species diver- in a rainforest area, and to set conservation prior- gence (Avise, 1994), implying that sometimes species ities accordingly.
