FIGURE 1 in Combining morphology and population genetic analysis uncover species delimitation in the widespread African tree genus Santiria (Burseraceae)
FIGURE 1. Genetic clusters (GC) detected in Santiria samples from western Central Africa. Bayesian clustering analyses were performed on 479 individuals genotyped at 10 microsatellites loci. A. Variation in means of Ln (likelihood) of the data as a function of the number of hypothetical genetic clusters (K), showing a plateau at K=3. B. Histogram of genetic assignment of the 481 individuals at K = 3. C. Distribution of the three genetic clusters in western Central Africa, and delimitation of the distribution of each genetic cluster (dotted line: GC1, solid line: GC2, dashed line: GC3). We extended the distribution ranges of GC2 and GC3 because morphotypes of both genetic clusters were observed in the south of the Republic of the Congo. Note: Interm. GCx and GCy = intermediate individuals between GCx and GCy.

FIGURE 3. WARD dendrogram of the studied populations based on ISSR markers. TCS network (Fig. 4) revealed that although species 1(R. straussii) is more distinct than the other two species but its accessions showed a high degree of intra-specific genetic variability as they are positioned in different places of the network.
