Root hairs and mycorrhiza represent alternative phylogenetically conserved strategies for belowground absorptive surface maximization

The paper measures root-hair traits and mycorrhizal colonization in 82 grassland species, finding a phylogenetic trade-off between root hairs and mycorrhiza.

Scale matters: the arbuscular mycorrhiza - root hair trade-off from individual plants to communities

This study examines the trade-off between arbuscular mycorrhiza and root hair traits across multiple scales in grassland plants, finding consistent patterns at community and interspecific levels but not at intraspecific or intra-individual levels.

Belowground functional traits predict population temporal stability in grasslands

The paper shows that root functional traits better predict population temporal stability in grasslands than aboveground traits, with land use intensity modifying these relationships.

Still standing: persistence traits capture belowground plant functions beyond resource exploration and acquisition

The paper integrates belowground plant traits to show persistence strategies are a critical dimension of plant function beyond resource acquisition and exploration.

The first spectrum of spore form and function reveals constrained evolution in mycorrhizal symbiosis

This study constructs the first quantitative morphospace of AM fungal spores, revealing that spore morphology evolves mainly through scaling rather than redesign.

Plant species richness and the root economics space drive soil fungal communities

The paper shows that plant species richness and root economics space axes influence soil fungal community composition in a grassland experiment.
