Supporting Figure 4 Fig. 4.
Model deviance was lowest when a distance-weighting exponent of –2 was used for calculating neighborhood abundances.

Supporting Figure 5 Fig. 5.
Observed and predicted annual changes in basal cover for B. curtipendula (a), B. hirsuta (b), and S. scoparium (c). Both observed and predicted changes are means across quadrats.

Table 2. Transition probabilities depend on probabilities of survival (S) and colonization (C).
