Digging deep to uncover plant–soil feedback variations
Plants influence the soils where they grow. While plant–soil feedback (PSF) plays an important role in plant community assembly and functioning, little is known about how PSF varies between different habitats and soil types. The EU-funded PlantSoilGradients project will research the variation in the strength and direction of PSF along soil fertility gradients in temperate grassland ecosystems at local to large spatial scales. Combining different disciplines – from plant ecology, soil science and population biology to evolutionary and microbial ecology – the project will build a mechanistic framework to predict PSF in different environmental contexts. The findings will assist in addressing global changes to biodiversity.
