Monitoring microbial diversity in European soils: ongoing projects and challenges
2012
SPEEcolDurGenoSolCT3communication orale invitée, résumé et slides; According to the Convention of Biological Diversity (Rio de Janeiro, 1992), biodiversity is the variation in life from genes to species, communities, ecosystems, and landscapes. Soils represent a huge reservoir of biodiversity which varies in terms of taxonomic richness, relative abundance and distribution according to soil types, climatic conditions, vegetation and land uses. The key functions supporting ecosystem services as identified in the Millennium Ecosystem Assessment (MEA, 2005) largely depend upon organisms that inhabit the soil. Thus, the design and implementation of a sustainable soil management strategy requires…
Impact of fertilization and direct seeding on activity and abundance of key denitrifier communities in a tropical soil
2007
Affiche, résumé; The aim of this work was to investigate to which extent different practices impacted on the bacterial communities involved in N2O emission.
Global Soil Biodiversity Atlas
2016
SPE EA Pôle BIOME The Atlas is divided in 8 chapters covering all the aspects of soil biodiversity: - Chapter I: The soil habitat - Chapter II: Diversity of soil organisms - Chapter III: Geographical and temporal distribution - Chapter IV: Ecosystem functions and services - Chapter V: Threats - Chapter VI: Interventions - Chapter VII: Policy, education and outreach - Chapter VIII: Conclusions Soil biodiversity experts from all over the world are involved in the project aiming at the creation of a reference publication not only for soil biodiversity researchers but also policy makers and general public.; International audience; The Global Soil Biodiversity Initiative (GSBI) and the Joint Res…

Technosols to reclaim industrial wastelands: depth distribution of abundance and activity of N-cycling microbial communities
2012
International audience; Construction of Technosols through assemblage of treated soil and recycled wastes is an innovative option for the restoration of degraded lands and re-use of industrial wastes. Recent studies have evidenced that Technosols could support soil functions such as primary production but the knowledge about other ecosystemic services, such as nutrient cycling, is limited. In this work, we investigated the abundance and the activity of microbial communities involved in N-cycling in different horizons (0–15, 15–35, 35–70 cm) of two types of Technosols constructed to reclaim an industrial wasteland. The estimation by real-time PCR of the abundances of the different microbial …
