microsatellite genotypes for all sample sets with >5 individuals

Microsatellite genotypes for 7 loci for 49 individuals of leafy seadragons (Phycodurus eques) in genepop format. Sample sets with <5 individuals and individuals of unknown geographic origin were excluded

Geographic distance matrix

Pairwise geographic distance in km between sample sets. Distance was measured along the coastline but straight-line connections were allowed across Spencer Gulf and Gulf St Vincent

microsatellite genotypes for all individuals

Microsatellite genotypes for 7 loci for all 70 individuals of leafy seadragons (Phycodurus eques) in genepop format

Sequences mitochondrial control region

Sequences of the mitochondrial control region for 56 leafy seadragons (Phycodurus eques) in fasta format

Geographic distance matrix South Australia

Pairwise geographic distance in km between sample sets, for South Australian sites only. Distance was measured along the coastline but straight-line connections were allowed across Spencer Gulf and Gulf St Vincent

Sequences mitochondrial NADH subunit 4 (ND4)

Sequences of the mitochondrial NADH subunit 4 (ND4) for 56 leafy seadragons (Phycodurus eques) in fasta format

Additional file 7:

28S gene tree of the complete dataset. The tree shown was inferred in MrBayes, branch labels are showing posterior probabilities and bootstrap values (PP/BS). Support values lower than 0.75/50 are not shown. An asterix (*) indicates PP = 1 and BS = 95–1, − indicates the node was not recovered in the best maximum likelihood tree. Identical sequences were removed prior to analyses. (TIFF 18438 kb
