This randomized trial explores nutrient acquisition strategies in phosphorus-limited tropical forests, indicating diverse root trait syndromes among species.
Key Points
The study aims to determine if root trait trade-offs affecting phosphorus acquisition in Southeast Asian forests align with global patterns.
Examined 33 species of AM and EcM fungi in old-growth and secondary forests in Singapore
Quantified root functional traits, including PME activity and mycorrhizal colonization rate
Analyzed root morphology and chemical traits related to phosphorus uptake
Two main axes of root trait variation related to soil exploration and resource conservatism were identified
Most species showed low mycorrhizal colonization independently of soil exploration traits
EcM species had thin roots with high specific root length, while AM species exhibited a variety of traits with thicker roots
