Effects of Formosan Macaques (Macaca cyclopis) on Seed Dispersal and Regeneration of Three Lauraceae Species at Fushan Experimental Forest Seed dispersal pattern: Distance of seed dispersed by macaques through check pouch correlated with the spatial distribution of fruiting trees. Seeds of parent trees with widely distribution pattern may be dispersed farther away from parent trees. Effects on seed fate: More seeds germinated in forest than in open area, and seedlings survived better in open area. Macaques may help disperse Lauraceae seeds to and establish at new place where gravity dispersal could not do.

Across 2 bars means significant different between ratios (paired t- test) More seeds of Machilus z. were dispersed to open area than in forest by Macaca cyclopis of 3 Lauraceae species at Fushan Experimental Forest. Across 2 bars means significant different between ratios (paired t- test) More seeds were dispersed in clump than scattered by Macaca cyclopis of 3 Lauraceae species at Fushan Experimental Forest.
