Seed limitation interacts with biotic and abiotic factors to constrain novel species' impact on community biomass and richness
Seed limitation can narrow down the number of coexisting plant species, limit plant community productivity, and also constrain community responses to changing environmental and biotic conditions. In a 10-year full-factorial experiment of seed addition, fertilisation, warming and herbivore exclusion,...
