Earth is experiencing environmental changes accelerating biodiversity erosion. Coral reefs are one of the most affected ecosystems by these changes because it relies on corals that leave at their upper thermal limit. Corals intraspecific diversity is crucial for their maintenance since it defines the adaptive potential of organisms in the face of current changes. Intraspecific diversity initially encompasses genetic, phenotypic and functional diversity within a species. However, non-genetically encoded elements such as the epigenetic information and the holobiont composition can vary between individuals and contribute to phenotypic adjustment. This project will combine sequencing technologies and innovative approaches to: i) better understand the spatial and temporal dynamics of intraspecific diversity in corals; ii) understand the genetic, epigenetic and microbial mechanisms of coral adaptation/acclimatization to thermal stress and iii) identify biomarkers of thermotolerance to enhance ecosystem management. These will be achieved by studying in space and time natural coral populations along an ecological gradient of thermal stress frequency and an integrative Omic approach.

The sequences of the 124 samples (control treatement) were carried out by the INTEGRAGEN platform. The samples of 3 species come from New Caledonia and French Polynesia.
