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.
