RT Journal Article SR Electronic T1 Geographic range size is predicted by plant mating system JF bioRxiv FD Cold Spring Harbor Laboratory SP 013417 DO 10.1101/013417 A1 Dena Grossenbacher A1 Ryan Briscoe Runquist A1 Emma E. Goldberg A1 Yaniv Brandvain YR 2015 UL http://biorxiv.org/content/early/2015/04/10/013417.abstract AB Species’ geographic ranges vary enormously, and even closest relatives may differ in range size by several orders of magnitude. With data from hundreds of species spanning 20 genera in 15 families, we show that plant species that autonomously reproduce via self-pollination consistently have larger geographic ranges than their close relatives that generally require two parents for reproduction. Further analyses strongly implicate autonomous self-fertilization in causing this relationship, as it is not driven by traits such as polyploidy or annual life history whose evolution is sometimes correlated with autonomous self-fertilization. Furthermore, we find that selfers occur at higher maximum latitudes and that disparity in range size between selfers and outcrossers increases with time since their separation. Together, these results show that autonomous reproduction — a critical biological trait that eliminates mate limitation and thus potentially increases the probability of establishment — increases range size.
