MOSCECO : Modelling, Scenarisation and Connectivity of the benthic biodiversity of Guadeloupe and Martinique.
Naturalist expeditions of the Muséum national d’Histoire naturelle (MNHN) produce an important amount of specimens occurrences, that are then identified by MNHN’s taxonomists network up until the species level. This database of species occurrences can be seen as a gloden standard for biodiversity science, on one hand thanks to the massive sampling effort deployed during the expedition, on the other hand thanks to the quality of taxonomic identification.
Natural History Collection (NHCs) datasets fuel numerous other fields in ecology, namely biogeography, functional ecology or conservation ecology. My work focus on using MNHN’s taxonomic inventory datasets in order to answer questions in ecology, notably through the MOSCECO project (Modelisation, Scenarisation and Connectivity of Guadeloupe & Martinique’s marine benthic coastal biodiversity).
This contract, funded by the French Biodiversity Office relies on occurrences from two well identified taxa (muricids and majoids) collected during expeditions Karubenthos 2012 & 2014 et Madibenthos 2016. The project aims at :
- Modelling species distribution through Joint Species Distribution Models (J-SDM) ;
- Characterize benthic communities’ connectivity through co-occurrence networks ;
- Evaluate the consequences of environmental variables alteration on distribution (first axis) & connectivity (second axis) of species.
Other existing (typology of Martinique’s marine habitats) and yet to be gathered datasets (coastal anthropic activities and pressures in Guadeloupe and Martinique) will be implemented in the analyses.
