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

Timothy J. Page & Jane M. Hughes
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...

Data from: Low inter-basin connectivity in a facultatively diadromous fish: evidence from genetics and otolith chemistry

Jane M. Hughes, Daniel J. Schmidt, Jed I. Macdonald, Joel A. Huey & David A. Crook
Southern smelts (Retropinna spp.) in coastal rivers of Australia are facultatively diadromous, with populations potentially containing individuals with diadromous or wholly freshwater life-histories. The presence of diadromous individuals is expected to reduce genetic structuring between river basins due to larval dispersal via the sea. We use otolith chemistry to distinguish between diadromous and non-diadromous life-histories and population genetics to examine inter-basin connectivity resulting from diadromy. Otolith strontium isotope (87Sr:86Sr) transects identified three main life history...

Data from: Changes in host-parasitoid food web structure with elevation

Sarah C. Maunsell, Roger L. Kitching, Chris J. Burwell & Rebecca J. Morris
Gradients in elevation are increasingly used to investigate how species respond to changes in local climatic conditions. While many studies have shown elevational patterns in species richness and turnover, little is known about how food web structure is affected by elevation. Contrasting responses of predator and prey species to elevation may lead to changes in food web structure. We investigated how the quantitative structure of a herbivore-parasitoid food web changes with elevation in Australian subtropical...

Data from: The relative roles of cultural drift and acoustic adaptation in shaping syllable repertoires of island bird populations change with time since colonization

Dominique A. Potvin & Sonya M. Clegg
In birds, song divergence often precedes and facilitates divergence of other traits. We assessed the relative roles of cultural drift, innovation and acoustic adaptation in divergence of island bird dialects, using silvereyes (Zosterops lateralis). In recently colonized populations, syllable diversity was not significantly lower than source populations, shared syllables between populations decreased with increasing number of founder events and dialect variation displayed contributions from both habitat features and drift. The breadth of multivariate space occupied...
