Fig. B1. Focal plants, fruiting neighbors, dispersed seeds and dispersal distances for the 20 focal *Tristerix croymbosus* mistletoes marked with enriched levels of ^{15}N. The left column shows the location and diameter (actual diameter in cm times 15 for visualization) of focal and neighboring mistletoes. The central column illustrates the location of dispersed seeds (empty circles for total number of seeds and red circles for labeled seeds estimated to be dispersed from the focal plant). The right column shows the histogram of dispersal distances of labeled seeds. In the histograms, labeled seeds collected in the 10–20 m quarters are aggregated at the 15-m class.

Fig. B2. Dispersal distances for all plants combined (20 *Tristerix croymbosus* mistletoes marked with enriched levels of ^{15}N). The line corresponds to a Negative Exponential distribution (mean = 2.80 m. SD = 0.15 m.) fitted to the dispersal distances excluding the labeled seeds collected in the 10–20 m quarters which are aggregated at the 15-m class.
