The bronze medal rewards initial research that has established a researcher as a specialist in their field. This distinction is a form of encouragement to pursue research that is already well underway and proving successful.
Florence Débarre, CNRS researcher at iEES Paris, is one of the 2022 CNRS talents rewarded for her research in evolutionary ecology and epidemiology and its implications for better understanding the evolution of the COVID19 virus.

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 […]

Great tits living in cities are genetically different from great tits in the countryside. This is what researchers have found in a unique study, where they examined populations of great tits in nine large European cities.
The researchers compared the city bird genes with the genes of their relatives in the countryside. It did not matter if the great tits lived in Milan, Malmö or Madrid: in order to handle an environment created by humans, the birds evolved in a similar way.

Climate changeaffectsbiodiversity globally, by forcing species to shift their distribution to track the changes in temperature. An international collaboration between scientists from France, Sweden, the Netherlands and Finland shows, in an article published in the journal Ecology Letters,that habitat fragmentation caused by human activity affects distribution shifts in butterfly species and, hence, their capacity to cope with climate change.

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 […]

“Here, we used 37 years of mark-recapture data in two nearby habitats inside a meadow viper Vipera ursinii population to quantify life expectancies, generation times and the shape of actuarial and reproductive senescence.”

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 […]

Researchers studied the genome of wasp species which attack different aphid species, in order to understand which adaptations allow them to get around their hosts’ defenses.
