Plantago lanceolata plants were grown under various environmental conditions in association with the mycorrhizal fungi Glomus mosseae , G. caledonium and a fine endophyte either individually or all together. Using a time‐course approach, we investigated the effects of elevated atmospheric CO 2 (eCO 2 ), soil warming and drought and their interactions on root length colonized (RLC) by mycorrhizal fungi and extraradical mycorrhi...

Plots containing Lolium perenne L., Trifolium repens L. or a mixture of both plant species were exposed to elevated atmospheric CO 2 (eCO 2 ) for 10 consecutive seasons using free‐air CO 2 enrichment technology at ETH Zürich, Switzerland. The CO 2 treatment was crossed with a two‐level nitrogen (N) fertilization treatment. In the tenth year, soil samples were collected on three occasions through the growing season to assess th...

Climate change treatments – winter warming, summer drought and increased summer precipitation – have been imposed on an upland grassland continuously for 7 years. The vegetation was surveyed yearly. In the seventh year, soil samples were collected on four occasions through the growing season in order to assess mycorrhizal fungal abundance. Mycorrhizal fungal colonisation of roots and extraradical mycorrhizal hyphal (EMH) densi...

Plantago lanceolata and Trifolium repens were grown under ambient (400 μmol mol –1 ) and elevated (650 μmol mol –1 ) atmospheric CO 2 conditions. Plants were inoculated with the arbuscular mycorrhizal fungus Glomus mosseae and given a phosphorus supply in the form of bonemeal. Six sequential harvests were taken in order to determine whether the effect of elevated CO 2 on internal mycorrhizal colonization and external hyphal pr...
