Abstract

Assessing how plants differ in their relative investment in nutrient-acquisition strategies aids understanding of species distribution. To examine how investment varies with scale (communities, species) in low phosphorus environments, I quantified colonisation by mycorrhizal fungi and examined root traits for plant communities across a phosphorus gradient in Brazil (campos rupestres) and grew two south-western Australian species (native to kwongan) under varying nutrient levels. Campos rupestres plants increased colonisation with increasing phosphorus availability. Increasing phosphorus supply influenced root morphology, but not colonisation in kwongan species. Investment in nutrient-acquisition strategies at different scales in campos rupestres and kwongan plants can predict species distribution.
