Body mass, skull dimensions and seed dispersal distances
Our analysis for primates only (N=16) detected significant covariation between body mass and seed dispersal distances and transit times, respectively (Rpls=0.73; P=0.01; Fig. 4). Small primates like e.g. tamarins (Leontocebus nigrifrons 11 Previously Saguinus fuscicollis (see Rylands et al.2016)) have short retention times and seed dispersal distances, while large primates such as gorillas (Gorilla gorilla ) have a long retention time and disperse seeds further.
An analysis excluding the body mass revealed significant co-variations between the skull dimensions and seed dispersal distances (Rpls=0.78; P=0.03). Coronoid height, the distance between molars, the projected and effective jaw length covaried with the transit times and seed dispersal distances (see Fig. 5).
