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.
A species of “murder hornet,” beheads and feeds to its larvae an insect that is very important to, and symbolic of, France: the honeybee.
J.-L. Janeau, IRD research engineer at iEES Paris (FEST and F2ZC teams), is co-organizer of an EGU21 session.
Based on the use of a smartphone application, the citizens of the three villages were invited to report water color changes, as these changes could reflect cyanobacteria proliferations.

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 […]

Soil carbon persistence can be understood through the lens of decomposers as a result of functional complexity derived from the interplay between spatial and temporal variation of molecular diversity and composition. For example, co-location alone can determine whether a molecule is decomposed, with rapid changes in moisture leading to transport of organic matter and constraining the fitness of the microbial community, while greater molecular diversity may increase the metabolic demand of, and thus potentially limit, decomposition.

Smaller organisms are typically more abundant than larger ones, which is a fundamental characteristic of ecological communities. How environmental pulse disturbances affect these « abundance pyramids » remains poorly understood. In a study recently published in Ecology Letters, researchers from iEES Paris and the University of Zürich showed that disturbances which are not size-selective still […]

Team publications Team members Pas de traduction pour cette page. Nous cherchons à comprendre et analyser expérimentalement ou par des observations, puis à représenter par des modèles couplés, les grands cycles de la matière (nutriments minéraux, carbone) en prenant en compte à la fois des processus classiquement étudiés en écologie des écosystèmes (ex : nitrification ou […]

Team publications Team members In the context of current large pressures exerted by human populations on natural communities, ecological sciences often cannot provide adequate predictions or management decisions. One reason is the intrinsic complexity of ecosystems. The EERI team tries to handle a part of this complexity by focusing on the structure, functioning and evolution […]

Team publications Team members The CoMiC team studies microbial communities in continental terrestrial and aquatic ecosystems in an interdisciplinary framework that combines microbiology, comparative genomics, metagenomics, chemistry, ecology, health, environmental sciences and social sciences. More specifically, our research focuses on (i) the vulnerability of microbial communities to disturbances and pollutants induced by human activity (ii) […]
