Persistence of soil organic carbon caused by functional complexity

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.

Environmental pulse disturbances disproportionately affect large body size species

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 […]

Environmental and ecological risks in southern countries

The interdisciplinary program “Environmental and Ecological Risks in the South” builds directly upon the existing, long-term research partnership that we have with our colleagues from developing and emerging countries. Indeed, one of the critical issues in research today is how to reconcile economic development with the preservation of the ecological integrity of the environment.To meet […]

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 […]

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 […]

Integrative Ecology : from Mechanisms to Ecosystem services “EMS” Team

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 […]

Microbial Communities in Continental ecosystems “CoMIC” Team

Team publications Team members We study the microbial communities of terrestrial and aquatic continental ecosystems in an interdisciplinary framework that blends microbiology and molecular biology, ecology, health and social sciences. Specifically, our research looks at (i) the diversity, functioning and roles of microbial communities within continental ecosystems, and (ii) the vulnerability of these communities to […]

Biogeography and Diversity of Interactions in Soil “BioDIS” Team

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 regulate or […]
