Veritable eco-ethological crossroads, coralligenous habitats present a complex three-dimensional structure and are home to one of the richest biocenoses in the Mediterranean Sea. Impacted by global change and local pressures, the study of these vulnerable coastal marine habitats is essential.
OBJECTIVES
This project aims to deepen our understanding of the relationships between the spatial structure of coralligenous habitats and the organisms that thrive there face to environmental change. The descriptors of these habitats will be linked to various environmental factors, in particular pressures linked to global change and local anthropic pressures.
The objectives will be to :
-
Develop innovative descriptors of the three-dimensional structuring of coralligenous habitats through the use of 3D modelling (digital twins).
-
Quantify changes in the three-dimensional structure of different coralligenous habitats in response to the effects of structuring factors.
-
Quantify the links between three-dimensional structure and the sessile and vagile communities of these habitats.
Pour arriver à ces objectifs, plusieurs actions seront organisées en premier temps comme la modélisation par photogrammétrie de la structure 3D de différents habitats coralligènes pour évaluer leur variabilité et les facteurs structurants, et la caractérisation des communautés sessiles et vagiles de ces habitats et analyse de leur variation en fonction de la structure 3D de leur habitat.
To achieve these objectives, a number of actions will be organized, such as photogrammetric modeling of the 3D structure of various coralligenous habitats to assess their variability and structuring factors, and characterization of the sessile and vagile communities of these habitats and analysis of their variation as a function of the 3D structure of their habitat.
