RESEARCH

  1. Coordinator of MONALISA (fortes MOrtalités NAturelles et Indicateurs pour la gestion des stocks de Sardines et Anchois de Méditerranée) project : environmental variability (in terms of oceanograhy and zooplankton) and its impact on small pelagic population dynamics, effect of prey quantity and quality on small pelagic life history traits, impact of hepatic parasitism on sardines and anchovies,
  2. Participating to POPSTAR project : development of new biologgers combining physiological and geographic information for marine fish
  3. Participating to seabream research programs (SB-TAG, SIGNAL)
  4. Research on seabird life-history traits and population dynamics, link between top-predators and forage fish

Previous projects :

  1. Coordinator of EcoPelGol (étude de la dynamique de l’ECOsystème PELagique du GOlfe du Lion) project : Understanding of small pelagic fish fluctuations in the Gulf of Lions. Test of bottom-up and top-down processes, effect of environmental conditions on small pelagic fish abundance, condition, distribution and life-history traits.
  2. Coordinator of ARPE project : epidemiology of small pelagics in the Gulf of Lions.

MARBEC MARine Biodiversity, Exploitation and Conservation, est une unité de recherche qui regroupe des personnels de 4 organismes : l’IRD, l’Ifremer, l’UM et le CNRS. Son objectif est l’étude de la biodiversité marine des écosystèmes lagunaires, côtiers et hauturiers à différents niveaux d’intégration, depuis les aspects moléculaires, individuels, populationnels et communautaires, et des usages de cette biodiversité par l’Homme.
