Literature search methodology
We conducted a systematic search for studies that examined the
relationship between dispersal-related traits and range size. We used
Web of Science and the Core Collection database with the key words
search criteria ”dispers*” OR ”dispers* trait” AND ”range size” OR
”species range” OR ”geogra* range”. We restricted our search to
scientific articles published in English. Our search yielded a total of
3,139 scientific articles. After a first screening based on article’
titles and abstracts, we discarded studies that were clearly irrelevant
(e.g., studies in other fields like physics, studies that do not
formally assess the dispersal - range size relationship, studies on
single species, studies that use genetic metrics as proxies of
dispersal, studies on range expansion or range shifts). We assessed 104
articles for eligibility by reading the full-text and we further
excluded perspectives and review articles or studies that did not
include empirical tests (i.e., strictly theoretical papers; see Table
S1-S4 in Database). After cross-referencing and including newly
published articles, 86 studies and 478 relationships between
dispersal-related traits and range size were included in our systematic
review. For an overview of the search methodology, see the Prisma
diagram (Fig. S1 Suppl. Mat.).
