Functional group richness increases multifunctionality in intensively managed grasslands Argens L, C Brophy, WW Weisser, S Meyer.

A paper studying multifunctionality using DI models. Both a multifunctionality index and a separate univariate model for each ecosystem function were used. The final model utilised the functional group interaction structure.

Scientific Reports (2021); 11, 1-16.

A paper studying the BEF relationship, using the multivariate DI model, and summarising results using a multifunctionality index on the predictions from the multivariate model. The final model chosen used a combination of the pairwise interaction and functional group structure.

Species interactions between forbs and grass-clover contribute to yield gains and weed suppression in forage grassland mixtures. Cong WF, M Suter, A Lüscher, J Eriksen.
Agriculture Ecosystems & Environment, (2018); 268, 154-161.

A paper assessing to what extent adding forb species to a grass-clover mixture results in yield gains and weed suppression. The contributions of the forbs’ identity and their interactions with the grass-clover mixture was analysed using DI models; the final model chosen had a functional group structure.

Greater gains in annual yields from increased plant diversity than losses from experimental drought in two temperate grasslands Finn, JA, M Suter, E Haughey, D Hofer, A Lüscher.

A paper assessing yield gains through the BEF relationship and relating these to yield losses from experimental drought using DI models with drought treatment on a split-plot design. The finally chosen model used an average interaction term.

The importance of species identity and interactions for multifunctionality depends on how ecosystem functions are valued Slade EM, L Kirwan, T Bell, CD Philipson, OT Lewis and T Roslin.
Ecology, (2017); 98, 2626-2639.

A paper using the multivariate DI model to assess 16 ecosystem functions in dung beetle communities, including a desirability index to aggregate predictions across functions.

Weed suppression enhanced by increasing functional trait dispersion and resource capture in forage ley mixtures Suter M, D Hofer, and A Lüscher.
Agriculture Ecosystems and Environment, (2017); 240, 329-339.

A paper using DI models to study weed suppression in functionally diverse grassland mixtures with high resource capture and biomass yield. The finally selected model had a functional group structure.

Effects of mixing forage species contrasting in vertical and temporal nutrient capture on nutrient yields and fertilizer recovery in productive grasslands Husse S, A Lüscher, N Buchmann, NJ Hoekstra and O Huguenin-Elie.
Plant and Soil, (2017); 420, 505-521.

A paper examining the benefit of mixing grass, legume, and forb species with complementary vertical and temporal nutrient capture on nutrient yields and fertilizer N recovery. The study used DI models; the final model chosen had a combination of the pairwise interaction and functional group structure.

Larger yields of mixtures than monocultures of cultivated grassland species match with asynchrony in shoot growth among species but not with increased light interception Husse S, O Huguenin-Elie, N Buchmann and A Lüscher.
Field Crops Research, (2016); 194, 1-11.

A paper using DI models to assess the effect of mixing four species with contrasting foliar architecture and seasonal shoot growth on yield formation. The final model chosen had a full pairwise interaction structure.

Yield of temperate forage grassland species is either largely resistant or resilient to experimental summer drought Hofer D, M Suter, E Haughey, J Finn, NJ Hoekstra, N Buchmann and A Lüscher.
Journal of Applied Ecology, (2016); 53, 1023-1034.

A paper evaluating resistance and resilience to an experimentally imposed severe drought event using DI models with drought treatment on a split-plot design. The finally selected model had a functional group structure.

Do belowground vertical niche differences between deep- and shallow-rooted species enhance resource uptake and drought resistance in grassland mixtures? Hoekstra NJ, M Suter, JA Finn, S Husse and A Lüscher.
Plant and Soil, (2015); 394, 21-34.

A paper studying whether the spatial differences in belowground niches between shallow- and deep-rooted species would result in increased resource uptake and drought resistance. The paper used DI models with a drought treatment; the finally selected model had a functional group structure.
