Data and analysis scripts to accompany: Coral genetic structure in the Western Indian Ocean mirrors ocean circulation and thermal stress history

With ever-growing concerns over the conditions of coral reefs under
warming oceans comes a need to better understand the connectivity and
adaptive capacities of reef-building corals from across large oceanic
regional extents. This dataset accompanies the published article by
Guillaume et al (2026) in Evolutionary Applications, where we applied a
seascape genomics approach to model (i) population connectivity and (ii)
thermal adaptive potentials for two keystone coral species across the West
Indian Ocean (WIO). Specifically, we sampled 345 Acropora
muricata and 403 Pocillopora damicornis individuals
around islands of three WIO regions–Seychelles, Mauritius, and
Rodrigues–as part of a UN development programme (UNDP; funding information
below). Genomic data were obtained from DNA extracted from sampled coral
tissue and sequenced with DArT-seq. We used a bioinformatic pipeline to
process and filter reads, which were then used to assess population
structure and connectivity, identify putative genomic regions under
thermal selection, and produce  maps of adaptive potential across
the WIO. This repository hosts one pdf per species that steps the user
through all the main analyses of the publication. These pdfs have been
produced using the Rmarkdown script provided, which will run when all the
accompanying data (sample information, environmental variables, genomic
data) are downloaded into one folder.
