Project description

Genomic horizons: studying octopuses’ response to climate change

The common octopus (Octopus vulgaris) has greatly increased in numbers in the northern Atlantic, but we do not yet understand why or how stable these populations are. Supported by the Marie Skłodowska-Curie Actions programme, the EVOLOCT project will investigate the past, present and future of these populations by analysing their genetics and using advanced computational models and environmental data. Unlike previous studies, this research will explore complex genetic changes, known as structural variants, to understand gene flow between populations and to reconstruct demographic histories. Additionally, it will predict future distributions, abundance and vulnerability. This information is crucial for the scientific management of fisheries and for deepening our understanding of how marine life responds to climate change.

Objective

Making the most of genomic tools to understand and predict species response to global change is increasingly important, especially in exploited marine species. In EVOLOCT, I aim to determine the genomic basis of local adaptation, while understanding the past, present, and future population dynamics of Octopus vulgaris. This ecologically and economically significant species has recently expanded northwards in the northeast Atlantic, possibly due to climate change or human exploitation, yet the exact causes and the population stability remain unknown. Moreover, while the importance of structural variants (SVs) has been increasingly recognised in underlying ecotypes and cryptic population structures, SVs remain poorly represented in eco-evolutionary studies. To address these gaps, I will integrate modelling, genomics, and environmental data to characterise present population structure and dynamics, reconstruct their demographic history, and predict their future distribution, abundance, and vulnerability. Pushing the boundaries of current genomics studies, I will incorporate SVs beyond the classic SNPs while combining simulated data with empirical data, as a powerful and comprehensive technique in predicting short- and long-term responses to climate change. I will hone my skills at the host lab of Dr Mérot alongside Prof Charrier and Dr Le Luyer, French experts in evolutionary biology and ecology. My secondment with Asst Prof Oomen in Sweden will expand my skills in modelling and SV analyses. Through these collaborations, I will learn new multidisciplinary approaches and techniques in modelling and genomics. EVOLOCT will undoubtedly enable me to gain a competitive advantage in establishing my career in the dynamic and critical field of evolutionary ecology. Finally, EVOLOCT will greatly advance our understanding of the genomic and evolutionary basis underlying local adaptation while allowing scientifically-informed management of exploited marine species like octopuses.
