T1 - Plant carbon investment infine roots and arbuscular mycorrhizal fungi: Across-biome study on nutrient acquisition strategies N2 - Plant resource acquisition strategies were ecosystem-specific with distinct mutualism with arbuscular mycorrhizal (AM) fungi. Root traits indicated conservative resource economics in the arid shrubland, but an acquisitive and self-sufficient (“do-it-yourself”) acquisition strategy in the semiarid coastal matorral, resulting in large carbon (C) investments (green). Forest plants with conservative root traits seem to intensively outsource their acquisition to AM fungi, compensating for lower uptake capacities of conservative roots (red line). High allocations of freshly assimilated C into AM fungal storage compounds illustrated the relevance of AM fungi as C sink, especially in the semiarid matorral.
