Nannoperca australis sampling locations in the Murray–Darling Basin (MDB). Stream sections are colour coded according to F ST estimated using the StreamTree model (Kalinowski et al., 2008). Cross markers represent the location of artificial in‐stream barriers. Admixture plot is based on 3,443 SNPs depicting K = 12 clusters determined by maximum marginal likelihood using fastStructure (Raj et al., 2014)
