Denis Vile, Bill Shipley, and Eric Garnier. 2006. A structural equation model to integrate changes in functional strategies during old-field succession. Ecology 87:504–517.

Appendix B. Estimation equations for pre-reproductive vegetative mass (Vm1). Abbreviation of species names are from Table 1. Equation coefficients: ai = partial slopes, b = intercept. Predictors: SL = stem length, SN = number of stem, NL = number of leaves, NGL = number of green leaves, H = Height. Harvest: M1 = first monitoring, D1 = first destructive harvest.
