Alexandre Che-Pelicier du laboratoire Molecular Surveillance, Environmental Science Department du Cawthron Institute, Auckland University of Technology, Earth Sciences New Zealand, donnera un séminaire à l’Amphithéâtre OCEANOMED, Bâtiment Méditerranée, Campus de Luminy, le mardi 16 juin 2026 à 13h00 sur le thème : Can stable isotopes and environmental DNA reveal the mysterious marine life of New Zealand eels?
Abstract
The spawning areas and larval dispersal pathways of two eel species from New Zealand remain unknown, leaving their life cycle still partially unresolved. Although tagging is used to track the movements of some marine animals, these methods are difficult to apply to both adult eels and their larvae (leptocephali). This presentation will focus on the use of biochemical and molecular markers to reconstruct the migration routes of these two species between the tropical Pacific Ocean and the temperate rivers of New Zealand.
Key words
Migrations marines, Leptocephales, Anguilles, Isotopes stables, Isoscapes, ADN environmental.
