The number of dispersal-related traits effect on the dispersal - range size relationship
Our results also indicated that including multiple dispersal-related traits increased the probability of finding a positive dispersal-range size relationship. However, 80% of the studied relationships (383/476) included only a single dispersal trait. As dispersal is an emergent process that results from the combined effects of multiple dispersal characteristics (Ronce 2007, Bonte et al. 2012), including multiple traits may capture the complexity of dispersal better, and thus increase the probability of finding a positive dispersal-range size relationship.
