Appendix D. Mixed model analysis of days from planting to emergence of G. tricolor seeds.

Fixed effects for the split-plot model are shown here, although the full model also included transect (nested within boundary type) and its interactions with population zone and removal treatment as random effects. Significance testing is based on restricted maximum likelihood. Population zone is a fixed factor with three levels: core population sites, edge sites, and peripheral sites beyond major population boundary. There are two population boundary types: the oak-canopy boundary and the valley bottom boundary. (N = 418)
