Press release
15 Nov 2019
Scientists from INRA and the Scuola Superiore Sant’Anna (Italy) have shown that not all weed communities (spontaneous vegetation) generate crop yield losses, even in unweeded conditions, and that high weed diversity is associated to a reduced risk of important crop yield losses. Published in Nature Sustainability, these results provide new grounds for sustainable weed management.

Researchers from INRA and CNRS1, in collaboration with German, Spanish, English and Canadian teams, have examined the effect of field size and crop diversity on biodiversity in agricultural landscapes. Published in PNAS, their work shows that increasing the complexity of the crop mosaic produces a considerable (and largely under-exploited) benefit in conserving and restoring the biodiversity of farm landscapes, while maintaining areas of land under agricultural production.

An international research team that included INRA and CNRS scientists has revealed the key role played by rare plant species in maintaining ecosystem "multifunctionality": both species and evolutionary diversity is important. Based on data from 123 sampling sites around the world, the results show that taxonomic, functional, and phylogenetic biodiversity matters for ecosystem functioning.

For the first time ever on a worldwide scale, an international team of researchers has demonstrated the positive influence of plant biodiversity on ecosystem stability. The team included researchers from INRA and the Chizé Centre for Biological Studies (CNRS, University of La Rochelle) and scientists from Argentina and Spain. Using satellite data and field surveys of 123 dryland sites around the world, researchers were able to show that biodiversity’s role in influencing ecosystems is as important as the role of climate or soil.

Our environment is experiencing a number of changes, from biodiversity losses to global warming. INRA researchers were involved in a comprehensive European study that demonstrated that high plant species diversity does not always reduce ecosystem vulnerability under climate extremes. T
