Molecular markers
FST values can be strongly affected by the genotyping
technique implemented (Nybom, 2004; Nybom & Bartish, 2000; Meirmans &
Hedrick, 2011), thus, we included this factor in our null model. In our
database, the majority of studies used nuclear microsatellites (140
species), followed by allozymes (114 species). Fewer studies used
dominantly inherited markers, including Amplified Fragment Length
Polymorphism (60 species), Random Amplification of Polymorphic DNA (16
species), and Inter-Simple Sequence Repeat (7 species).
