Les projets de notre \u00e9quipe sont centr\u00e9s sur l\u2019\u00e9volution du comportement animal et l\u2019influence des comportements sur l\u2019\u00e9volution et la sp\u00e9ciation. Ainsi deux th\u00e9matiques principales sont abord\u00e9es : l’\u00e9tude de l’\u00e9volution comportementale et de la sp\u00e9ciation chez la drosophile, et l’\u00e9volution des syst\u00e8mes sensoriels chez les insectes. <\/p>\n\n\n\n

Th\u00e9matique 1 : Comportement et sp\u00e9ciation chez la drosophile<\/mark> <\/a><\/h2>\n\n\n\n

L\u2019origine de nouvelles esp\u00e8ces est l\u2019une des questions les plus fondamentales de la biologie \u00e9volutive. En nous appuyant sur l\u2019h\u00e9ritage unique de notre laboratoire dans l\u2019\u00e9tude de la sp\u00e9ciation chez les drosophiles, et en incorporant de nouvelles m\u00e9thodes en g\u00e9nomique, g\u00e9n\u00e9tique et neurobiologie, nous explorons diff\u00e9rentes facettes des interactions entre sp\u00e9ciation et comportement. Nous supposons que les g\u00e8nes responsables des changements de comportement peuvent \u00eatre li\u00e9s de mani\u00e8re pl\u00e9iotropique aux locus sous-jacents aux divergences physiologiques et morphologiques, favorisant finalement la sp\u00e9ciation.<\/p>\n\n\n\n

Th\u00e9matique 2 : Evolution des syst\u00e8mes sensoriels chez les Hym\u00e9nopt\u00e8re<\/mark>s<\/a><\/h2>\n\n\n\n

Les syst\u00e8mes sensoriels sont \u00e0 l\u2019interface entre l\u2019environnement des animaux d\u2019une part et leur physiologie et leur comportement d\u2019autre part. Ils d\u00e9terminent la fa\u00e7on dont les animaux per\u00e7oivent le monde, et y r\u00e9pondent par leur comportement. Par cons\u00e9quent, notre hypoth\u00e8se de travail est que l\u2019\u00e9volution des syst\u00e8mes sensoriels joue un r\u00f4le central dans l\u2019adaptation des comportements aux changements environnementaux ou \u00e0 l\u2019occupation de nouvelles niches \u00e9cologiques. En combinant de nouvelles m\u00e9thodes en g\u00e9nomique, g\u00e9n\u00e9tique et neuro\u00e9thologie, nous explorons diff\u00e9rentes facettes de l’\u00e9volution des syst\u00e8mes sensoriels, en particulier chimiosensoriels, et leur implication dans une transition majeure dans l\u2019organisation du vivant, i.e. l\u2019apparition du plus haut degr\u00e9 de vie sociale (eusocialit\u00e9). Nos mod\u00e8les d’\u00e9tude sont principalement des insectes hym\u00e9nopt\u00e8res, ordre connu pour avoir connu au moins 9 \u00e9mergences ind\u00e9pendantes de l\u2019eusocialit\u00e9. Nous travaillons donc sur des hym\u00e9nopt\u00e8res sociaux (abeilles domestiques, bourdons, gu\u00eapes vespid\u00e9es et fourmis) mais aussi solitaires (gu\u00eapes parasites, abeilles solitaires, etc).<\/p>\n\n\n\n
