Scientific Interests

Vent faunal distribution and biodiversity partitioning in a fragmented ridge system: the West Pacific back-arc basins.

My project aims at studying the structure of hydrothermal vent faunal biodiversity at a broad range of spatial scales in the West Pacific back-arc basins and understanding the factors that control this biodiversity (i.e. connectivity, geological settings, physico-chemical environment). Thus, I am focusing on two types of communities characteristic of these areas: mussel beds of Bathymodiolus and gastropod assemblages dominated by Ifremeria and Alviniconcha. I will characterize the species assemblages by combining a classical morphological approach and a barcoding approach to detect possible cryptic species. I will use novative uni- and multivariate analyses to compare biodiversity components within a basin and between basins and to describe their relationships to measured environmental data. In addition I will also study some characterstics of population dynamics (reproduction and size-structure) of dominant gastropod taxa using gonad histology and classical microscopy and analyze their variations in relation to environmental conditions.
