Paul Kardol, Nelleke J. Cornips, Monique M. L. van Kempen, J. M. Bakx-Schotman, and Wim H. van der Putten. 2007. Microbe-mediated plant–soil feedback causes historical contingency effects in plant community assembly. Ecological Monographs 77:147–162.

Appendix I. Results of t tests to analyze if inocula effects for early-successional plant species and mid-successional plant species differed from zero. Inocula effects were calculated as biomass production in soil with microbial inocula relative to soil without these inocula. N = 5. The inocula originated from soils with histories of the early-successional species A. geniculatus, A. spica-venti, P. annua, C. bursa-pastoris, C. canadensis, and V. arvensis. N = 5.
