R\u00f4le de la pr\u00e9dation dans l\u2019att\u00e9nuation des impacts \u00e9cologiques d\u2019esp\u00e8ces non-natives<\/h2>\n

Description du projet<\/h3>\n

Le sujet de th\u00e8se testera donc l’hypoth\u00e8se d’un effet des Salmonid\u00e9s sur l’impact des vairons, et sera structur\u00e9 en trois objectifs. Le premier quantifiera l’effet des Salmonid\u00e9s sur l’habitat des vairons, d\u00e9terminant si leur pr\u00e9sence force les vairons \u00e0 modifier l’utilisation de leur habitat, passant d’un habitat p\u00e9lagique \u00e0 littoral. Une approche bas\u00e9e sur les isotopes stables et des mesures morphologiques des vairons \u00e9valuera si les Salmonid\u00e9s influencent leur morphologie et leur utilisation des ressources. Les communaut\u00e9s de zooplancton seront aussi \u00e9tudi\u00e9es pour tester les liens entre la morphologie des vairons et la structure des communaut\u00e9s. Le second objectif testera les relations causales entre la variation morphologique des vairons et la structure des communaut\u00e9s. Des exp\u00e9riences en m\u00e9socosmes permettront de mettre en \u00e9vidence les potentiels effets non-l\u00e9taux comme le stress et les modifications comportementales induites par la pr\u00e9dation, gr\u00e2ce par des odeurs de pr\u00e9dateurs, et leurs r\u00e9percussions sur les \u00e9cosyst\u00e8mes. Le dernier objectif visera \u00e0 identifier des m\u00e9canismes par lesquels la pr\u00e9dation influence les impacts \u00e9cologiques des vairons via des caract\u00e9ristiques morphologiques, physiologiques et comportementales des vairons. Une exp\u00e9rimentation sera conduite en jardin commun pour quantifier les diff\u00e9rences de ces caract\u00e9ristiques entre des vairons expos\u00e9s ou non \u00e0 une odeur de pr\u00e9dateur. Les r\u00e9sultats attendus contribueront \u00e0 mieux comprendre les interactions entre esp\u00e8ces introduites et \u00e9cosyst\u00e8mes, offrant des perspectives pour une gestion plus durable de ces milieux.<\/p>\n
