| 1 | Functional group richness increases multifunctionality in intensively managed grasslands显示文摘Background:Agricultural yields have increased continuously over the last few decades.However,a focus solely on production can harm the environment.Diversification of agriculture has been suggested to increase production and sustainability.Biodiversity experiments showed positive effects on ecosystems and productivity.However,application of these results to intensively managed grasslands has been questioned due to differences in plant species and management regimes.Research on whether diversity can benefit multifunctionality,that is,an integrated index of multiple ecosystem functions,under intensive management,is still scarce.Methods:To address this,we manipulated plant species richness from one to six species spanning three functional groups(legumes,herbs,and grasses)in intensively managed multispecies grassland leys and examined seven ecosystem functions.Results:We found that multifunctionality increased with functional group and species richness.Legume+herb mixtures showed high multifunctionality,while grass monocultures and mixtures with high proportions of grasses had low multifunctionality.Different plant species and plant communities drove different ecosystem functions.Legumes and herbs improved productivity and water availability,while grasses enhanced invasion resistance.These results indicate that multifunctionality and individual ecosystem functions can be promoted through targeted combinations of plants with complementary ecological traits.Conclusions:Plant diversity can improve multifunctionality also under intensive management,potentially benefitting agroeconomics and sustainability. | Laura Argens Caroline Brophy Wolfgang W.Weisser Sebastian Meyer | 2023 | Grassland Research2023，2，3： | 0 |
