“…In no case did soil N and CO 2 interact Rice et al 1994), but protozoa were not counted. The proportion of AM roots was not aected by soil N or elevated CO 2 for yellow poplar (O'Neill et al 1987), cotton , white clover (Jongen et al 1996), and C 3 grasses (Monz et al 1994), but increased in response to both soil N and elevated CO 2 in Artemisia tridentata (Klironomos et al 1996). However, as O'Neill et al (1987 pointed out, since root system mass increased, mycorrhizal mass increased proportionally.…”

“…Root infection responses to elevated CO 2 have rarely been reported at the plant community level for complex natural communities, but mostly for single-species experiments (e.g., Dhillion et al 1996), or per plant species for co-occurring plants (Monz et al 1994;Rillig et al 1998). Whitbeck (1994) observed no or no consistent percent colonization responses to CO 2 in these same serpentine and sandstone grasslands.…”

“…So far it is dicult to predict symbiotic responses to elevated CO 2 because AM studies historically have focused on fungal bene®ts to the host (Whitbeck 1994;Allen 1996). Several studies have shown no eect of CO 2 on percent mycorrhizal colonization, although AM-colonized root length sometimes increased (O'Neill et al 1991;Rogers et al 1994;Runion et al 1994;Whitbeck 1993Whitbeck , 1994Monz et al 1994). Monz et al (1994) working with Bouteloua gracilis, Klironomos et al (1996) with Artemisia tridentata, Jongen et al (1996) with Trifolium repens, and Sanders (1996) with Prunella vulgaris observed increases in percent infection by AM fungal structures in response to elevated CO 2 .…”
