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).
