Data from: Phylogenetic uncertainty and taxonomic re-revisions: an example from the Australian short-necked turtles (Testudines: Chelidae)

Phillip Q. Spinks, Arthur Georges & H. Bradley Shaffer
Molecular data have greatly influenced our concepts of species and their relationships in the last few decades, and as a consequence the taxonomy of most vertebrate clades has been repeatedly revised to reflect phylogeny. However, as larger and more complete molecular data sets become available, the sometimes striking disparities between taxonomic revisions based on individual gene trees (particularly those based on mitochondrial DNA) and species trees has become increasingly apparent. Here, we present data from...

Data from: Citizen science program shows urban areas have lower occurrence of frog species, but not accelerated declines

Understanding the influence of landscape change on animal populations is critical to inform biodiversity conservation efforts. A particularly important goal is to understand how urban density affects the persistence of animal populations through time, and how these impacts can be mediated by habitat provision; but data on this question are limited for some taxa. Here, we use data from a citizen science monitoring program to investigate the effect of urbanization on patterns of frog species...

Data from: A bust but no boom: responses of floodplain bird assemblages during and after prolonged drought

Katherine E. Selwood, Rohan H. Clarke, Shaun C. Cunningham, Hania Lada, Melodie A. McGeoch & Ralph Mac Nally
1. Climate change alters the frequency and severity of extreme events, such as drought. Such events will be increasingly important in shaping communities as climate change intensifies. The ability of species to withstand extreme events (resistance) and to recover once adverse conditions abate (resilience) will determine their persistence. 2. We estimated the resistance and resilience of bird species during and after a 13-year drought (the ‘Big Dry’) in floodplain forests in south-eastern Australia. 3. We...

Data from: An examination of the accuracy of a sequential PCR and sequencing test used to detect the incursion of an invasive species: the case of the red fox in Tasmania

David S. L. Ramsey, Anna J. MacDonald, Sumaiya Quasim, Candida Barclay & Stephen D. Sarre
1. Polymerase Chain Reaction (PCR) diagnostic tests are increasingly applied to the identification of wildlife. Yet rigorous verification is rare and the estimation of test accuracy (the probability that true positive and true negative samples are correctly identified – test sensitivity and specificity, respectively), particularly in combination with sequencing, is uncommon. This is important because PCR-based tests are prone to contamination in sampling and the laboratory. 2. Here, we use an experimental case–control approach to...

Data from: An invasive non-native mammal population conserves genetic diversity lost from its native range

Andrew J. Veale, Olivia J. Holland, Robbie A. McDonald, Mick N. Clout, Dianne Gleeson & D.M. Gleeson
Invasive, non-native species are one of the major causes of global biodiversity loss. Although they are, by definition, successful in their non-native range, their populations generally show major reductions in their genetic diversity during the demographic bottleneck they experience during colonization. By investigating the mitochondrial genetic diversity of an invasive non-native species, the stoat Mustela erminea, in New Zealand and comparing it to diversity in the species’ native range in Great Britain, we reveal the...

Data from: A model-derived short-term estimation method of effective size for small populations with overlapping generations

Annegret Grimm, Bernd Gruber, Marion Hoehn, Katrin Enders & Klaus Henle
If not actively managed, small and isolated populations lose their genetic variability and the inbreeding rate increases. Combined, these factors limit the ability of populations to adapt to environmental changes, increasing their risk of extinction. The effective population size (Ne) is proportional to the loss of genetic diversity and therefore of considerable conservation relevance. However, estimators of Ne that account for demographic parameters in species with overlapping generations require sampling of populations across generations, which...

Data from: Groundwater salinisation intensifies drought impacts in forests and reduces refuge capacity

Jarrod Kath, Sue Powell, Kathryn Reardon-Smith, Sondoss El Sawah, Anthony J. Jakeman, Barry F. W. Croke & Fiona J. Dyer
1. Shallow groundwater aquifers regularly support drought refuges for water-dependent ecosystems. However, many aquifers are impacted by over-extraction and pollution, potentially degrading their ability to support groundwater-fed drought refuges. 2. We investigated the response of groundwater-connected riverine forests to a drought considered equivalent in intensity to those predicted under severe climate change for 2030. The drought's impact was investigated in an area where shallow groundwater resources are heavily exploited and polluted by salinization. 3. We...
