Photos from the Field: Seed dispersal by gibbons and macaques

McConkey, K. R., Brockelman, W. Y. and Saralamba, C. (2014), Mammalian Frugivores With Different Foraging Behavior Can Show Similar Seed Dispersal Effectiveness. Biotropica, 46: 647–651. doi: 10.1111/btp.12156

Frugivores with disparate foraging behavior are considered to vary in their seed dispersal effectiveness (SDE). Measured SDEs for gibbons and macaques for a ‘primate-fruit’ were comparable despite the different foraging and movement behavior of the primates. This could help facilitate fruit trait convergence in diverse fruit–frugivore networks.
