Appendix A. Figures showing changes in juvenile–adult associations over time.

FIG. A1. Associations between A. dumosa adults and juveniles for each census interval. Positive associations are contoured in red and negative associations are contoured in blue. Contours of positive associations consistently predominate over time. Although the specific location of positive and negative contours is slightly spatially variable over time, the lower left corner of the study site is consistently a region of positive association between juveniles and adults of A. dumosa.

FIG. A2. (a) Associations between E. fasciculatum adults and juveniles and (b) associations between A. dumosa adults and E. fasciculatum juveniles for each census interval where E. fasciculatum juveniles were present. Positive associations are contoured in red and negative associations are contoured in blue. Although slightly variable in location, positive associations predominate over all censuses.
