Using a network of 100 winter wheat fields selected to encompass a gradient of years in conservation agriculture from 1 to 20 years in the Bourgogne-Franche-Comte region (France), we analyzed the changes that occurred in the diversity of weed communities over several years, both in \u03b1- and \u03b2-diversity using a taxonomic (species level) and functional (10 response traits) approach. Based on three weed surveys (before the last herbicide use, before harvest, before sowing the following crop), we identified weeds able to maintain and/or to produce propagules. All the observed weed communities were rich (average species richness of 23.9 species), diverse (average Shannon diversity of 2.15) and equitably composed of low-density species. The results showed an increase in species richness, total weed abundance and \u03b1-functional diversity but no change in species diversity and species evenness over time. Heterogeneity and average values of \u03b2-taxonomic and \u03b2-functional diversity between communities were high in the early years following the adoption of conservation agriculture. Heterogeneity and average \u03b2-taxonomic and \u03b2-functional diversity decreased over time, leading to a homogenization of weed community assemblages. Despite major changes in cultural practices related to conservation agriculture, homogenization of weed community was not immediate and did not concern all the traits studied.", "keywords": ["[SDE] Environmental Sciences", "0106 biological sciences", "2.

There is widespread concern that cessation of grazing in historically grazed ecosystems is causing biotic homogenization and biodiversity loss. We used 12 montane grassland sites along an 800 km north\uffe2\uff80\uff93south gradient across the UK, to test whether cessation of grazing affects local \uffce\uffb1 - and \uffce\uffb2 -diversity of below-ground food webs. We show cessation of grazing leads to strongly decreased \uffce\uffb1 -diversity of most groups of soil microbes and fauna, particularly of relatively rare taxa. By contrast, the \uffce\uffb2 -diversity varied between groups of soil organisms. While most soil microbial communities exhibited increased homogenization after cessation of grazing, we observed decreased homogenization for soil fauna after cessation of grazing. Overall, our results indicate that exclusion of domesticated herbivores from historically grazed montane grasslands has far-ranging negative consequences for diversity of below-ground food webs. This underscores the importance of grazers for maintaining the diversity of below-ground communities, which play a central role in ecosystem functioning.
