Worker size diversity does not improve colony success in the ant Temnothorax nylanderi

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 […]

Urban ecology

Google traduction de la page en français The transversal program “Urban Ecology” was initiated for this purpose with the objectives: to animate research in this field to federate and develop inter-team and inter-department projects within iEES Paris develop partnerships with local actors and authorities (association, municipality, etc.) In recent years, the urban environment has been […]

Ecological Functioning of Temperate and tropical Soils “FEST” Team

Team publications Team members The main objective of the FEST team is to better understand the interactions between biological actors and the abiotic properties of soils, and the impact of these interactions on the resulting ecosystem services. In particular, we study the influence of soil engineers (especially earthworms, termites and microbial activity) and their “productions” […]

Social Species in their Environments : Adaptation and Evolution “ESEAE” Team

Team publications Team members The aim of the ESEAE team is to understand how social life influences the mechanisms of evolution and adaptation of social species, their biodiversity, and their interactions with other species.  Environmental changes are a central theme. Our biological models are mainly termites and ants. We use an integrative approach that focuses on morphology, physiology, […]

City and forest ants are surprisingly similar genetically

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.
