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 […]

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 : […]

Team news 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 […]

Team news 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 […]

Team news Team publications Team members The objectives of BIOgeography and Diversity of Interactions in Soil (BioDis) team is to analyse these interactions in their environmental context in order to better understand the functioning and evolution of soils. The strategy that we have adopted is to study biotic interactions, whilst accounting for the abiotic constraints that […]

In this prospective article, an international consortium coordinated by researchers from the University of Copenhagen examines the prospects for using the “third dimension” of agricultural land, i.e. the possibility, without resorting to new land, of increasing the volume of soil exploited by the root system of crops, thereby increasing the resource base available for agricultural production while minimizing the undesirable externalities frequently associated with current agroecosystems.

For more than 10 years, the City of Paris and the Institute of Ecology and Environmental Sciences of Paris have been collaborating on various issues of urban ecology. From these multiform collaborations at the interface between fundamental research and concrete techniques for the management of urban environments, several advances have been made on both scientific […]
