Data from: Genetic diversity and drivers of dwarfism in extinct island emu populations

Vicki A. Thomson, Kieren J. Mitchell, Rolan Eberhard, Joe Dortch, Jeremy J. Austin & Alan Cooper
Australia’s iconic emu (Dromaius novaehollandiae novaehollandiae) is the only living representative of its genus, but fossil evidence and reports from early European explorers suggest that three island forms (at least two of which were dwarfs) became extinct during the 19th century. While one of these - the King Island emu - has been found to be conspecific with Australian mainland emus, little is known about how the other two forms - Kangaroo Island and Tasmanian...

Data from: Incorporating non-equilibrium dynamics into demographic history inferences of a migratory marine species

Emma L. Carroll, Rachael Alderman, John L. Bannister, Martine Bérubé, Peter B. Best, Laura Boren, C. Scott Baker, Rochelle Constantine, Ken Findlay, Robert Harcourt, Louisiane Lemaire, Per J.

Understanding how dispersal and gene flow link geographically separated populations over evolutionary history is challenging, particularly in migratory marine species. In southern right whales (SRWs, Eubalaena australis), patterns of genetic diversity are likely influenced by the glacial climate cycle and recent history of whaling. Here we use a dataset of mitochondrial DNA (mtDNA) sequences (n=1,327) and nuclear markers (17 microsatellite loci, n=222) from major wintering grounds to investigate circumpolar population structure, historical demography, and effective...

Data from: Environmental DNA metabarcoding studies are critically affected by substrate selection

Adam Koziol, Michael Stat, Tiffany Simpson, Simon Jarman, Joseph D. DiBattista, Euan S. Harvey, Michael Marnane, Justin McDonald & Michael Bunce
Effective biomonitoring is critical for driving management outcomes that ensure long-term sustainability of the marine environment. In recent years environmental DNA (eDNA), coupled with metabarcoding methodologies, has emerged as a promising tool for generating biotic surveys of marine ecosystems, including those under anthropogenic pressure. However, more empirical data is needed on how to best implement eDNA field sampling approaches to maximise their utility for each specific application. The effect of the substrate chosen for eDNA...

Data from: The cascading pathogenic consequences of Sarcoptes scabiei infection that manifest in host disease

Alynn M. Martin, Tamieka A. Fraser, John A. Lesku, Kellie Simpson, Georgia L. Roberts, Jillian Garvey, Adam Polkinghorne, Christopher P. Burridge & Scott Carver
Sarcoptic mange, caused by the parasitic mite Sarcoptes scabiei, causes a substantive burden of disease to humans, domestic animals, and wildlife, globally. There are many effects of S. scabiei infection, culminating in the disease which hosts suffer. However, major knowledge gaps remain on the pathogenic impacts of this infection. Here, we focus on the bare-nosed wombat host (Vombatus ursinus) to investigate the effects of mange on: (i) host heat loss and thermoregulation, (ii) field metabolic...

Data from: Population genetic signatures of a climate change driven marine range extension

Jorge E. Ramos, Gretta T. Pecl, Natalie A. Moltschaniwskyj, Jayson M. Semmens, Carla A. Souza & Jan M. Strugnell
Shifts in species distribution, or ‘range shifts’, are one of the most commonly documented responses to ocean warming, with important consequences for the function and structure of ecosystems, and for socio-economic activities. Understanding the genetic signatures of range shifts can help build our knowledge of the capacity of species to establish and persist in colonised areas. Here, seven microsatellite loci were used to examine the population connectivity, genetic structure and diversity of Octopus tetricus, which...
