  abstract = {{A}nomalous heat waves are causing a major decline of hard corals around the world and threatening the persistence of coral reefs. {T}here are, however, reefs that have been exposed to recurrent thermal stress over the years and whose corals appear to have been tolerant against heat. {O}ne of the mechanisms that could explain this phenomenon is local adaptation, but the underlying molecular mechanisms are poorly known. {I}n this work, we applied a seascape genomics approach to study heat stress adaptation in three coral species of {N}ew {C}aledonia (southwestern {P}acific) and to uncover the molecular actors potentially involved. {W}e used remote sensing data to characterize the environmental trends across the reef system, and sampled corals living at the most contrasted sites. {T}hese samples underwent next generation sequencing to reveal single nucleotide polymorphisms ({SNP}s), frequencies of which were associated with heat stress gradients. {A}s these {SNP}s might underpin an adaptive role, we characterized the functional roles of the genes located in their genomic region. {I}n each of the studied species, we found heat stress-associated {SNP}s located in proximity of genes involved in pathways well known to contribute to the cellular responses against heat, such as protein folding, oxidative stress homeostasis, inflammatory and apoptotic pathways, and {DNA} damage-repair. {I}n some cases, the same candidate molecular targets of heat stress adaptation recurred among species. {T}ogether, these results underline the relevance and the power of the seascape genomics approach for the discovery of adaptive traits that could allow corals to persist across wider thermal ranges.},
