Chez les insectes sociaux, la diversité de taille des individus dans les colonies est supposée améliorer la division du travail et ainsi augmenter la fitness des colonies. Cela fait relativement consensus chez les espèces à forte diversité de taille continue ou bien avec la présence de plusieurs castes non reproductrices. En revanche, chez les espèces à diversité plus limitée, représentant la grande majorité des insectes sociaux, les résultats sont plus contrastés. Cette thèse s’est donc focalisée sur l’intérêt de la taille des ouvrières au sein des colonies de fourmis à diversité modérée. Nous avons dans un premier temps démontré que la taille moyenne et la diversité de taille des ouvrières ne sont pas forcément adaptatives chez notre espè...
