Data from: Contrasting insights provided by single and multispecies data in a regional comparative phylogeographic study

Many single-species freshwater phylogeographic studies have been carried out in south-east Queensland, however comparative phylogeography requires multiple lines of evidence to infer deep, significant relationships between landscape and biota. The present study aimed to test conclusions resulting from single taxon studies in a multispecies comparative framework: (1) how influential are river basins in the genetic structure of freshwater species; (2) are there biogeographic frontiers between groups of basins; and (3) could deep intraspecific lineages be explained by a single event?
