Abstract: The roots of species coexistence Theory suggests that the presence of multiple limiting resources within an ecosystem allows for trade-offs between species, promoting the potential for coexistence. William Harpole and colleagues test this theory in plant communities, using data from the international Nutrient Network collaboration. They compile data from multi-year nutrient enrichment experiments carried out on 45 grassland sites on five continents to show that the addition of an increasing number of nutrients leads to a reduction in plant species diversity. The findings suggest that competition for below-ground resources promotes plant species diversity.
