-- CONTEXT -- 

The conservation of marine biodiversity requires a better understanding of population dynamics and connectivity. Recent genetic approaches based on genomically identical descent (IBD) segments allow for the reconstruction of demography and migratory flows at timescales relevant to conservation. However, their application to marine fish must take into account their complex life cycles (high fecundity, overlapping generations, sequential hermaphroditism, etc.).

-- OBJECTIVES -- 

My doctoral research project is structured around three complementary axes:

(1) Evaluating the robustness of spatial demographic inference methods based on IBD segments, incorporating the biological characteristics of marine species.

(2) Characterizing the dispersal and connectivity of the common seabream (Diplodus sargus) to understand how exchanges between populations and marine protected areas (MPAs) contribute to maintaining genetic diversity and local recruitment.

(3) Studying the recovery dynamics of the dusky grouper (Epinephelus marginatus) population following protection measures, identifying the role of self-recruitment, immigration, and super-breeders.
