In containers, plants and microbes together supported productivity
Both kinds of diversity went along with ecosystem functioning across 101 grasslands. In containers, they jointly supported production and nutrients.
The study, in plain language
A grassland depends on both visible plants and soil organisms. To explore their combined contribution, the team brought together observations from six continents and an experiment that varied plant diversity, microbial diversity, and water availability.
In the field, plant and soil-organism diversity each accounted for distinct and shared parts of differences in functioning among grasslands. In containers, their interactions supported plant production and nutrient storage. The field pattern varied with aridity: fungal richness had a more positive relationship in less arid areas, and plant richness in more arid areas.
The key idea
Plants and microbes contribute to grasslands partly separately and partly together, and the balance varies with aridity.
Something to think about
The next time you look at a grassland, remember that the greenery is only part of the story: organisms beneath the surface also contribute.
The original study
Aboveground and belowground biodiversity have complementary effects on ecosystem functions across global grasslands
