Fig. 3: RAD-seq based population structure of Porites cf. lobata.
From: Palau’s warmest reefs harbor thermally tolerant corals that thrive across different habitats
a STRUCTURE for K = 4. Rock Island sites are shown first (left of orange triangle), followed by outer reef sites (right of triangle). RI sites are dominated by light blue (LB) and red lineages (RD) while the dark blue (DB) and pink lineages (PI) are more common on the outer reefs. b Principal component analyses of RAD-seq data. Points represent individual samples and are colored by their dominant lineage (>50% assigned lineage based on STRUCTURE results). c Discriminant analysis of principal components (DAPC) recapitulates the four lineage clusters. Points are individual samples, colored by their dominant lineage assignment. Top inset shows number of retained principal components for analysis (70) based on cross-validation optimization. Lower inset shows density across the first discriminant axis. d Pairwise Nei’s FST values between lineages. Background color intensity increases with higher FST.
