Figure 2. Comparison of the average OTU relative abundance of AMF associated with the Collinsia sparsiflora ecotype populations in the field versus in a common garden.

C. sparsiflora ecotypes populations (S1, S2, NS1, and NS3) were grown in a) the field (Schechter and Bruns (2008) or grown in b) a common garden of mixed serpentine and non-serpentine AMF in the greenhouse.
