As part of a partnership with the City of Paris, several members of the laboratory (Basile Finand, Céline Bocquet, Pierre Federici, Thibaud Monnin et Nicolas Loeuille (“EERI” Team of “DCFE” Department and “ESEAE” Team of “EcoEvo” Department) sample the soil fauna and in particular the ants in the Parisian green spaces. To popularize and explain this […]

Social groups consist of individuals that differ from one another, and many studies show that this diversity improves group efficiency. In social insects, size diversity can, for example, improve the efficiency of foraging, nest building, brood rearing and production of young queens. Thus, colonies that re more diverse are generally also more efficient. Romain Honorio […]

City life could lead to differential evolution between urban and forest populations. Aurelie Khimoun and her collaborators showed, in their article published in Biology Letters, that urban populations of the tiny acorn ant are surprisingly not genetically differentiated from forest populations, suggesting expansion and lack of isolation. However, some genes display traces of selection that point towards an adaptation to the urban environment.
