Mixed effects of agricultural practices and agro-ecological structures on grassland plant diversity
International audience For a long time, descriptive and experimental studies have shown that agricultural practices affect plant diversity in permanent grasslands. More recently, landscape organization and, more particularly, spatial organization of agroecological structures (AES) was identified as...
