Marine mammal ecology and feeding strategies
Currently working on my thesis at the CEBC, my research focuses on the feeding ecology of marine mammals, and on the identification of their resource acquisition strategies (at the colony and individual scales). My study models are the marine calf seal and the grey seal, which I study in a particular ecological context: at the southern limit of their European range (along the French coasts of the English Channel). ResearchGate
My objective is to identify the trophic/food niche of the sea-calf and grey seals, in the North-East Channel, in order to assess the potential overlap between these two species and the associated (potentially competitive) interactions. This work is based on different axes: the study of the diet of these two species (by analysis of faeces/stomach contents), the use of ecological markers (stable isotopes in the vibrissae), and the assessment of their hunting areas (by analysis of dive and spatial data from telemetric monitoring; GPS/GSM beacons fitted on seals). The acquisition of all these data allows me to get a good picture of the seal’s trophic/food niche, spatially and temporally, and also to identify the individual hunting strategies that structure this niche.
