- Yann FRÉJAVILLE
I have been a researcher in marine ecology since 2007. My doctorate, obtained at the University of the West Indies (Guaseloupe island), was a study of the ichthyological colonization of coral reefs.
I then went abroad (Madagascar, Ghana ...) to focus on research applied to conservation (highlighting the influence of the "reserve effect", study of the impact of destructive fishing and anthropogenic activities on marine biocenoses, study of the optimal parameters for the creation of MPAs ...).
Back in Guadeloupe as part of a post-doctorate, I have the opportunity to perfect my experience in these two aspects of my career as an ecologist through the following two programs:
• CÁYOLI: Environmental program of the Grand Port Maritime de la Guadeloupe (2020-2022)
The CÁYOLI program (www.cayoli.fr) aims to develop and implement concrete solutions adapted to the restoration of coastal ecosystems.
In addition to contributing to a better knowledge of the dynamics of marine and coastal ecosystems under the management of the GPMG (setting up of rigorous ecological monitoring), the program has acquired research and development resources concerning, in particular:
- Reef fish (capture-culture-reintroduction of post-larvae),
- Marine phanerogam beds (nursery by sowing),
- Mangroves (nurseries by collecting and cultivating mangrove propagules) ...
• DIDILAC: Diversity and dispersal of Caribbean reef fish (2020-2021)
The DIDILAC project (led by C. DROMARD of the RECAP team) is a multidisciplinary approach aimed at studying the recruitment of post-larvae of reef fish on the reefs of the Caribbean, with three main objectives:
1) assess the composition and diversity of the larval community using a metagenomic approach,
2) estimate the pelagic lifespan of larvae of two model species using a sclerochronological approach,
3) define the influence of sea currents on larval recruitment using a micro- current approach.
