a Scatter plot of the first two principal components for samples collected in 2021 and based on 8,329,442 variant sites using a whole genome genotype likelihood approach. Each point represents a unique coral colony and is colour coded by site. Dashed lines represent 95% confidence ellipses for each site. b Tiled heatmap of genetic differentiation (pairwise FST Weir and Cockerham, 1984) among sites in 2021 using a reduced dataset of 29,462 single nucleotide polymorphisms with more strict depth filters (depth > 10). Warmer colours indicate higher values (Supplementary Data 1). c Genotype composition plot of assignment probabilities for individuals (vertical bars) to predefined groups based on year of collection (K = 5) using the temporal genetic dataset of microsatellite genotypes.
