No off-season for insect pollinators in the city!

In the city, the seasonal patterns of activity of insect pollinators could be disturbed by the urban microclimate as well as by the presence of ornamental flora. To study this phenomenon, Vincent Zaninotto and his collaborators monitored the activity of insect pollinators in Paris and in the natural environment, from late winter to autumn. In […]

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 […]

Molecular Ecophysiology of Stressed plant “EcophyS” Team

Team publications Team members Google traduction de la version française The Molecular Ecophysiology of the plant under stress (EcoPhyS) team is studying the responses of plants to environmental constraints by developing an integrative approach to the study of the response to environmental constraints, of plants whole (gas exchange, biomass production, yield) down to the cellular […]

Neuroethology of olfaction “NeO” Team

Team publications Team members Our experimental and modelling studies aim at understanding the mechanisms involved in the recognition of the olfactory signal and its translation in a behavioural response adapted to the environment and the physiological state of insects.These studies concern the processes of sensory coding, from the chemo-electrical transduction in the olfactory receptor neurones to […]

Chemoreception and Adaptation “CreA” Team

Team publications Team members The team investigates the mechanisms of olfactory and gustatory reception in the peripheral sensory systems and their plasticity in a changing biotic and abiotic environment.We take into account the evolutionary, adaptive and ecophysiological / ecotoxicological contexts. Our questions are : What are the chemical landscapes the insects leave in ? What are […]
