Fig. 1.

Frequency distribution of seeds dispersed over given distance classes (seed dispersal kernel). (A) Shown are the relative contributions of major frugivore groups to different distance classes within the study population. Open bars, small- to medium-size frugivorous birds, including, e.g., E. rubecula, P. ochruros, T. merula, and Sylvia spp.; light grey, T. viscivorus; dark grey, C. corone; black, carnivorous mammals, including V. vulpes, M. foina, and M. meles. (B) Shown is the weighted contribution of each dispersal vector to seed immigration to the study population (dispersal distances ≥ 1,500 m); i.e., fruits consumed in fruiting trees growing in other populations with the seeds being regurgitated or defecated in the study population. For each disperser group, the proportion of immigrant seeds in the genotyped sample was weighted by the overall contribution to fruit removal.
