The aim of this presentation is to give you an overview of my academic and research background, as well as to present some of my previous research projects. I am a non-permanent lecturer and researcher in behavioural ecology, with a research background focused on the study of\u00a0<\/span>behaviour and interactions in aquatic vertebrates, mainly fish and amphibians. My scientific career began with a degree in Biology, followed by a Master\u2019s degree in Ethology, and then a PhD at the University of Lorraine. My PhD research, conducted in the context of aquaculture, focused on\u00a0<\/span>intra-cohort cannibalism during the early life stages of pikeperch,\u00a0<\/span>using a multi-trait approach to investigate the behavioural and individual determinants of this phenomenon. Since then, my research has progressively expanded towards the study of\u00a0<\/span>individual variability, social interactions and group structure,\u00a0<\/span>with a particular interest in the behavioural mechanisms underlying relationships between individuals and responses to environmental constraints. My research has addressed topics including\u00a0<\/span>intra- and interspecific interactions, anti-predator behaviour, animal personality, behavioural ontogeny, early life development, group structure, and the consequences of individual variability for fitness.\u00a0<\/span>I use experimental approaches under controlled conditions (ex situ), as well as observations and experiments conducted under conditions closer to the natural environment (in situ). My research background also has a strong applied dimension, particularly in relation to\u00a0<\/span>aquaculture, aquatic population management, and invasive alien species. My recent projects at the University of Angers have focused on\u00a0<\/span>interactions between native amphibians and invasive alien species, as African clawed frog\u00a0<\/span>Xenopus laevis<\/i>\u00a0<\/i><\/span>and\u00a0<\/i><\/span>pumpkinseed sunfish\u00a0<\/span>Lepomis gibbosus<\/i>.<\/span><\/p>\n

L’objectif de ma pr\u00e9sentation est de vous montrer mon parcours et quelques-uns de mes projets de recherche ant\u00e9rieurs. Je suis enseignante-chercheuse contractuelle en \u00e9cologie comportementale, avec un parcours centr\u00e9 sur l\u2019\u00e9tude des comportements et des interactions chez les vert\u00e9br\u00e9s aquatiques, principalement les poissons et les amphibiens. Mon parcours scientifique a d\u00e9but\u00e9 par une formation en biologie puis en \u00e9thologie, avant un doctorat \u00e0 l\u2019Universit\u00e9 de Lorraine. Ma th\u00e8se, men\u00e9e dans le contexte de l\u2019aquaculture, portait sur le\u00a0cannibalisme intra-cohorte chez les premiers stades de vie du sandre\u00a0<\/span>Sander lucioperca<\/i>, avec une approche multi-traits visant \u00e0 comprendre les d\u00e9terminants comportementaux et individuels de ce ph\u00e9nom\u00e8ne. Depuis, mes recherches se sont progressivement \u00e9largies vers l\u2019\u00e9tude de la\u00a0variabilit\u00e9 interindividuelle, des interactions sociales et de la structure des groupes, en m\u2019int\u00e9ressant notamment aux m\u00e9canismes comportementaux impliqu\u00e9s dans les relations entre individus et dans les r\u00e9ponses aux contraintes environnementales. Mes travaux abordent notamment les\u00a0interactions inter- et intrasp\u00e9cifiques, les comportements anti-pr\u00e9dateurs, la personnalit\u00e9 animale, l\u2019ontogen\u00e8se des comportements, le d\u00e9veloppement des premiers stades de vie, la structure des groupes et les cons\u00e9quences de la variabilit\u00e9 individuelle sur les performances et la fitness. J\u2019utilise des approches exp\u00e9rimentales en conditions contr\u00f4l\u00e9es (ex-situ), mais \u00e9galement des observations et exp\u00e9rimentations en conditions plus proches du milieu naturel (in-situ). Mon parcours comprend \u00e9galement une forte dimension appliqu\u00e9e, notamment autour de l\u2019aquaculture, de la gestion des populations aquatiques et des esp\u00e8ces exotiques envahissantes. Mes projets r\u00e9cents \u00e0 l’Universit\u00e9 d’Angers ont port\u00e9 sur les interactions entre amphibiens autochtones et esp\u00e8ces exotiques envahissantes dont le x\u00e9nope\u00a0<\/span>Xenopus laevis<\/i>\u00a0<\/span>et la perche soleil\u00a0<\/span>Lepomis gibbosus<\/i>.<\/p>\n","protected":false},"excerpt":{"rendered":"
