Weed control provided by seed predators saves 20 % crop yield in cereal fields

Lucile Muneret, Benjamin Carbonne, Bruno Chauvel, Alexandre Dosset et autres

Although many herbicide active substances have been banned, and while weed infestation is a major threat to crop productivity, the extent to which natural weed control provided by seed predators can help farmers manage weed communities remains unknown. The contribution of seed …

Reduced temporal turnover in carabid communities enhances biomass stability in agricultural landscapes

Lucile Muneret, Audrey Alignier, Benoît Ricci, Alexandre Dosset et autres

While the temporal stability of plant communities has been well investigated, almost nothing is known about the inter-annual stability of arthropod communities, especially those inhabiting highly disturbed habitats such as croplands. We investigated the effects of landscape, management and community drivers on …

Pollinator functional group abundance and floral heterogeneity in an agroecological context affect mating patterns in a self‐incompatible wild plant

Audrey Labonté, Valérie Le Corre, Annick Matéjicek, Émeline Felten et autres

PREMISE: Restoration of seminatural field margins can elevate pollinator activity. However, how they support wild plant gene flow through interactions between pollinators and spatiotemporal gradients in floral resources remains largely unknown. METHODS: Using a farm-scale experiment, we tested how mating outcomes (expected …

Natural weed seed predators reduce crop yield loss due to weeds by 20% in cereal fields

Lucile Muneret, Benjamin Carbonne, Bruno Chauvel, Alexandre Dosset et autres

Abstract While many herbicide active substances have been banned and weed infestation is a major threat to crop productivity, it is still unknown to what extent natural weed control provided by seed predators can help farmers manage weed communities. We aim to …

Ancient varieties can help control weed density while preserving weed diversity

Ana Ailén Federico, Eric Pimet, Arnaud Coffin, Chantal Ducourtieux et autres

Weeds are a major component of agricultural diversity affecting crop yield and ecosystem services. Compared to modern wheat (Triticum aestivum) varieties, ancient wheat cultivars (released before 1960) are taller, and this trait can be used to control weeds in organic farming systems. …

Species richness enhances natural enemy biomass stability by decreasing their temporal turnover in agricultural landscapes

Lucile Muneret, Audrey Alignier, Benoît Ricci, Alexandre Dosset et autres

While the temporal stability of communities of natural enemies in agroecosystems is crucial to sustain pest control services over time, little is known about what drives this stability. Using a 6-year dataset composed of carabid collections, together with local and landscape-level management …

Carabid beetles have hump‐shaped responses to disturbance and resource gradients within agricultural landscapes

Lucile Muneret, Benoît Ricci, Aude Vialatte, Stéphanie Aviron et autres

Abstract Understanding the effects of the huge diversity of cropping systems on local biodiversity is challenging but necessary to implement agroecological systems. Through a functional approach, the translation of cropping systems into resource and disturbance gradients is a promising way to decipher …

Individual flowering phenology shapes plant–pollinator interactions across ecological scales affecting plant reproduction

Audrey Labonté, Lucie S. Monticelli, Mélinda Turpin, Émeline Felten et autres

Abstract The balance of pollination competition and facilitation among co‐flowering plants and abiotic resource availability can modify plant species and individual reproduction. Floral resource succession and spatial heterogeneity modulate plant–pollinator interactions across ecological scales (individual plant, local assemblage, and interaction network of …
