Plant biomass, rather than species composition, determines ecosystem properties: Results from a long‐term graminoid removal experiment in a northern Canadian grassland

Human‐induced environmental change is occurring globally and alters ecosystem properties both directly, by changing abiotic conditions, and indirectly, by modifying community composition. The effects of changes in plant composition in determining ecosystem properties may be determined by the identity of the plants, their respective biomass in the community and also by the ability of remaining vegetation to compensate for their loss. We used the...
