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. Huang, Ching-lun & Lee, Ling-Ling Institute of Ecology and Evolutionary Biology, National Taiwan University, Taipei, 106, Taiwan (A) (B) (C) Introduction Distances Habitats Densities Distance Seed density 2.How recruitment effected by: 1.Whats the seed dispersal pattern Methods Follow and record macaques feeding (on Lauraceae tree), moving, and seed dispersal pattern. Results I. Seed dispersal pattern: Figure 1. The ratio of seeds spat by Formosan Macaques in every 10 meters after leaving parent trees. (A) Litsea acuminata (Litsea a.) (B) Machilus zuihoensis var. mushaensis (Machilus m.) (C) Machilus zuihoensis (Machilus z.) II. Fates of dispersed seeds: - Seed germination rate & seedling survival rate (A)(B)(C)(D) (A)(B)(C)(D) Macaca cyclopis dispersed more seeds away from than under parent trees of 3 Lauraceae species at Fushan Experimental Forest. 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. Across 2 bars means significant different between ratios (paired t- test) Litsea acuminata: Seeds germinated more in forest than in open area (ANOVA, p
