Florence Débarre, CNRS bronze medal !

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.

The invasion of hammerhead flatworms is not over yet

In the the last years, predatory land flatworms have been introduced in many locations because of the trade of exotic plants. In this article published in Diversity and Distributions, a collaboration between iEES Paris, the National Museum of Natural History and James Cook University aimed to model the global invasion risk of these species. It turns out that they have not colonised all regions at risk yet, which demonstrates a need for increased vigilance in these areas.

Cirad – Crop diversification enhances yields, biodiversity and ecosystem services

The article, published in Global Change Biology on 18 July 2021, assembles for the first time a substantial body of empirical evidence on the positive impacts of cultivated biodiversity on agroecosystems.
Crop diversification was found to enhance crop production by 14% and associated biodiversity by almost 25%. Water quality was improved by 50%, pest and disease control by over 63% and soil quality by 11%.

How to live in the city when you are an ant? (Live City of Paris)

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 […]

Habitat fragmentation prevents species from tracking climate change

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.

Not just honeybees: predatory habits of Vespa velutina (Hymenoptera: Vespidae) in France

Our results suggest that V. velutina is a generalist opportunistic predator targeting mostly locally abundant prey. While the species may have an impact on honeybees, its generalist, opportunistic behaviour on abundant insects suggests a minor impact on wild species.
