Plant species natural abundances are determined by their growth and modification of soil resources in monoculture

The abundance of a plant species in a diverse community may depend on two aspects of a plant’s resource niche: its ability to garner limiting resources for its own growth, and its ability to reduce resources available for other species. Given that these two aspects of niche can be quantified in monoculture, we tested whether plant growth or plant modification of soil resources in monoculture relate to plant abundance in naturally-assembled...
