Plant species responses to nutrient addition, but not to herbivore exclusion, strengthen over time in global grasslands

It is demonstrated that global change impacts on plant community composition can be driven by shifts in a subset of species, and the utility of identifying key drivers of compositional shifts in grasslands worldwide is demonstrated.

Nutrient enrichment and herbivore exclusion disrupt the climate-driven balance between C3 and C4 plants in grasslands

The distribution of plants with different photosynthetic pathways is strongly structured by climate, with C3 plants favoured in cooler temperate regions and C4 plants in hotter, high-light conditions. The relative abundance of C3 and C4 plants across the world has cascading impacts on local food webs, decomposition, pr...
