Data from: Long-term data suggest jarrah-forest establishment at restored mine sites is resistant to climate variability

Rachel J. Standish, Matthew I. Daws, Aaron D. Gove, Raphael K. Didham, Andrew H. Grigg, John M. Koch & Richard J. Hobbs
1. Global climate change is projected to increase the frequency and intensity of drought in dry regions due to warming temperatures and declining rainfall. Severe drought can trigger tree mortality and drive persistent vegetation change. 2. To date, most empirical studies have focused on drought-induced mortality of adult trees, but this needs to be matched by similar efforts to understand drought impacts on seedling establishment if we are to understand the resilience of the world's...

Data from: Local genetic patchiness but no regional differences between Indo-West Pacific populations of the dogtooth tuna Gymnosarda unicolor

Physical barriers can have profound impacts on dispersal in marine species. Here, we investigate population structure and levels of relatedness among individuals of the coral reef associated fish, the dogtooth tuna Gymnosarda unicolor, collected from 15 sites across the Indo-West Pacific region. We screened 92 individuals for genetic variation at 13 nuclear microsatellite loci and the cytochrome oxidase subunit 1 (CO1) mitochondrial DNA (mtDNA) gene. We detected no genetic differentiation between ocean basins or between...

Data from: Resistance and resilience to changing climate and fire regime depend on plant functional traits

Neal J. Enright, Joseph B. Fontaine, Byron B. Lamont, Ben P. Miller & Vanessa C. Westcott
Changing disturbance-climate interactions will drive shifts in plant communities: these effects are not adequately quantified by environmental niche models used to predict future species distributions. We quantified the effects of more frequent fire and lower rainfall - as projected to occur under a warming and drying climate - on population responses of shrub species in biodiverse Mediterranean-climate type shrublands near Eneabba, southwestern Australia. Using experimental fires, we measured the density of all shrub species for...

Data from: It is premature to regard the ego-depletion effect as ‘too incredible’

Martin S. Hagger & Nikos L. D. Chatzisarantis
The ‘strength’ model conceptualizes self-control as a limited resource (Baumeister et al., 1998). Individuals are able to exert self-control, but only for a limited period after which capacity declines leading to reduced self-control capacity; a state known as ego-depletion. The model has generated a sizable literature confirming the ego-depletion effect in multiple spheres. Our meta-analysis of published ego-depletion studies computed a medium-sized effect (d=0.62) across 198 tests (Hagger et al., 2010). Carter and McCullough (2013)...

Data from: Management of behavioural change in patients presenting with a diagnosis of dementia: a video vignette study with Australian general practitioners

Moyez Jiwa, Pam Nichols, Parker Magin, Georgina Pagey, Xingqiong Meng, Richard Parsons & Vinita Pillai
Objective: To test the impact of feedback on the proposed management of standardised patients presenting with behavioural change with a diagnosis of dementia in Australian primary care. Materials and methods: A video vignette study was performed with Australian general practitioners (GPs) in 2013. Participants viewed six pairs of matched videos depicting people presenting changed behaviour in the context of a dementia diagnosis in two phases. In both phases GPs indicated their diagnosis and management. After...

Data from: Silent fish surveys: bubble-free diving highlights inaccuracies associated with SCUBA-based surveys in heavily fished areas

Steven J. Lindfield, Jennifer L. McIlwain, Euan S. Harvey & Andrew R. Halford
1. Underwater visual census (UVC) using SCUBA is a commonly used method for assessing reef fish communities. Evidence suggests, however, that fish avoid divers due to the sound of bubbles produced by open-circuit SCUBA, and avoidance behaviour is more pronounced as fishing pressure increases. Despite the potential for producing biased counts and conclusions, these behavioural effects have rarely been quantified, especially when assessing the effectiveness of marine protected areas (MPAs). 2. To test the magnitude...

Data from: Calibration of pelagic stereo-BRUVs and scientific longline surveys for sampling sharks

Julia Santana-Garcon, Matias Braccini, Tim J. Langlois, Stephen J. Newman, Rory B. McAuley & Euan S. Harvey
1. Our understanding of the ecology of sharks and other highly mobile marine species often relies on fishery-dependent data or extractive fishery-independent techniques that can result in catchability and size-selectivity biases. Pelagic Baited Remote Underwater stereo-Video Systems (pelagic stereo-BRUVs) provide a standardized, non-destructive and fishery-independent approach to estimate biodiversity measures of fish assemblages in the water column. However, the performance of this novel method has not yet been assessed relative to other standard sampling techniques....

Data from: A randomised trial deploying a simulation to investigate the impact of hospital discharge letters on patient care in general practice.

Moyez Jiwa, Xingqiong Meng, Carolyn O’Shea, Parker Magin, Ann Dadich & Vinita Pillai
Objective: To determine how the timing and length of hospital discharge letters impact on the number of ongoing patient problems identified by general practitioners (GPs). Trial design: GPs were randomised into four groups. Each viewed a video monologue of an actor-patient as he might present to his GP following a hospital admission with 10 problems. GPs were provided with a medical record as well as a long or short discharge letter, which was available when...

Data from: Does genetic distance between parental species influence outcomes of hybridisation among coral reef butterflyfishes?

Stefano R. Montanari, Jean-Paul A. Hobbs, Morgan S. Pratchett, Line K. Bay & Lynne Van Herwerden
Christmas Island is located at the overlap of the Indian and Pacific Ocean marine provinces and is a hot spot for marine hybridization. Here, we evaluate the ecological framework and genetic consequences of hybridization between butterflyfishes Chaetodon guttatissimus and Chaetodon punctatofasciatus. Further, we compare our current findings to those from a previous study of hybridization between Chaetodon trifasciatus and Chaetodon lunulatus. For both species groups, habitat and dietary overlap between parental species facilitate frequent heterospecific...
