Sydney I. Glassman and Brenda B. Casper. 2012. Biotic contexts alter metal sequestration and AMF effects on plant growth in soils polluted with heavy metals. Ecology 93:1550–1559. http://dx.doi.org/10.1890/10-2135.1

Appendix E (Table E1). ANOVA for the effects of soil, source of AMF, and source of non-mycorrhizal soil microbes on percent colonization of roots by AMF, percent colonization of roots by NMF, and number of NMF morphotypes per root of Deschampsia flexuosa individuals. Abbreviations as in Appendix C.
