Journal ArticleDOI
Soil aggregation and carbon sequestration are tightly correlated with the abundance of arbuscular mycorrhizal fungi: results from long-term field experiments
TL;DR: An experimental field study involving long-term diverse management practices of native multispecies prairie communities invariably showed a close positive correlation between AMF hyphal abundance and soil aggregation, and C and N sequestration, suggesting there are serious consequences to the loss of AMF from ecosystems.
Journal ArticleDOI
Mycorrhizae influence plant community structure and diversity in tallgrass prairie
TL;DR: The results of this study demonstrate that mycorrhizal symbiosis can have large effects on plant community structure, and that differential host species response to fungal colonization is a key factor explaining the dominance of warm- season C4 grasses in tallgrass prairie and limiting plant species evenness and diversity.
Journal ArticleDOI
Interspecific variation in plant responses to mycorrhizal colonization in tallgrass prairie
TL;DR: There was a strong and significant relationship between phenology of prairie grasses and mycorrhizal responsiveness, however this relationship was less apparent in forbs, and plant growth responsiveness and AM root colonization were positively correlated for the nonleguminous species, with this relationship being strongest for the cool-season grasses.
Journal ArticleDOI
Host plant species effects on arbuscular mycorrhizal fungal communities in tallgrass prairie
TL;DR: The demonstration that host plant species composition influences AM fungal species composition provides support for current feedback models predicting strong regulatory effects of soil communities on plant community structure.
