Data from: In-kennel behavior predicts length of stay in shelter dogs

Alexandra Protopopova, Lindsay Renee Mehrkam, May Meredith Boggess & Clive David Lawrence Wynne
Previous empirical evaluations of training programs aimed at improving dog adoption rates assume that dogs exhibiting certain behaviors are more adoptable. However, no systematic data are available to indicate that the spontaneous behavior of shelter dogs has an effect on adopter preference. The aim of the present study was to determine whether any behaviors that dogs exhibit spontaneously in the presence of potential adopters were associated with the dogs' length of stay in the shelter....

Data from: Opportunistic records reveal Mediterranean reptiles’ scale‐dependent responses to anthropogenic land use

Thomas De Solan, Ian Renner, Marc Cheylan, Philippe Geniez & Jean-Yves Barnagaud
Although classified among the greatest threats to the world's biodiversity, the effects of land use and their scale dependency are left unexplored in many taxonomic groups. Reptiles are among the most data‐deficient vertebrates in this respect, although their ecological traits make them highly sensitive to habitat modifications. We tested whether land use gradients shape the distributions of Mediterranean reptiles at regional and local scales, and whether species’ ecological traits and phylogeny explain these patterns. Reptiles...

Data from: It’s a trap! invasive common mynas learn socially about control-related cues

Marie C. Diquelou & Andrea S. Griffin
Social learning of novel threats coupled with adaptive generalization from learned to novel cues together provide the cognitive mechanisms by which adaptive avoidance of threats can spread rapidly both within and across generations. Whereas attention to effects of fishing and hunting on prey is increasing, nothing is known about how human predation can alter the behavior of invasive animals. Here, we examined whether common (Indian) mynas, Acridotheres tristis, one of the most widespread invasive birds...

Data from: Elevated salinity blocks pathogen transmission and improves host survival for a globally pandemic disease: implications for amphibian translocations

Simon Clulow, John Gould, Hugh James, Michelle Stockwell, John Clulow & Michael Mahony
1. Emerging infectious diseases are one of the greatest threats to global biodiversity. Chytridiomycosis in amphibians is perhaps the most extreme example of this phenomenon known to science. Translocations are increasingly used to fight disease-induced extinctions. However, many programs fail because disease is still present or subsequently establishes in the translocation environment. There is a need for studies in real-world scenarios to test whether environmental manipulation could improve survival in populations by generating unfavourable environmental...

Data from: Reconfiguration of functional brain networks and metabolic cost converge during task performance

Andreas Hahn, Michael Breakspear, Lucas Rischka, Wolfgang Wadsak, Godber Godbersen, Verena Pichler, Paul Michenthaler, Thomas Vanicek, Marcus Hacker, Siegfried Kasper, Rupert Lanzenberger & Luca Cocchi
The ability to solve cognitive tasks depends upon adaptive changes in the organization of whole-brain functional networks. However, the link between task-induced network reconfigurations and their underlying energy demands is poorly understood. We address this by multimodal network analyses integrating functional and molecular neuroimaging acquired concurrently during a complex cognitive task. Task engagement elicited a marked increase in the association between glucose consumption and functional brain network reorganization. This convergence between metabolic and neural processes...

eDNA metabarcoding survey reveals fine-scale coral reef community variation across a remote, tropical island ecosystem

Katrina West, Michael Stat, Euan Harvey, Craig Skepper, Joseph DiBattista, Zoe Richards, Michael Travers, Stephen Newman & Michael Bunce
Environmental DNA (eDNA) metabarcoding, a technique for retrieving multi-species DNA from environmental samples, can detect a diverse array of marine species from filtered seawater samples. There is a growing potential to integrate eDNA alongside existing monitoring methods in order to establish or improve the assessment of species diversity. Remote island reefs are increasingly vulnerable to climate-related threats and as such there is a pressing need for efficient whole-ecosystem surveying approaches to baseline biodiversity, study assemblage...

Data from: Do singles or couples live healthier lifestyles? trends in Queensland between 2005-2014

Stephanie Schoeppe, Stephanie J. Alley, Amanda R. Rebar, Melanie Hayman, Mitch J. Duncan & Corneel Vandelanotte
Objectives: To compare the frequency of and trends in healthy lifestyle factors between singles and couples. Methods: Cross-sectional data from annual surveys conducted from 2005-2014 were used. The pooled sample included 15,001 Australian adults (mean age: 52.9 years, 50% male, 74% couples) who participated in the annual Queensland Social Survey via computer-assisted telephone interviews. Relationship status was dichotomised into single and couple. Binary logistic regression was used to assess associations between relationship status, and the...

Data from: Rare long-distance dispersal of a marine angiosperm across the Pacific Ocean

Timothy M. Smith, Paul H. York, Bernardo R. Broitman, Martin Thiel, Graeme C. Hays, Erik Van Sebille, Nathan F. Putman, Peter I. Macreadie & Craig D. H. Sherman
Aim: Long-distance dispersal (LDD) events occur rarely but play a fundamental role in shaping species biogeography. Lying at the heart of island biogeography theory, LDD relies on unusual events to facilitate colonisation of new habitats and range expansion. Despite the importance of LDD, it is inherently difficult to quantify due to the rarity of such events. We estimate the probability of LDD of the seagrass Heterozostera nigricaulis, a common Australian species, across the Pacific Ocean...

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: A congruent phylogenomic signal places eukaryotes within the Archaea.

Tom A. Williams, Peter G. Foster, Tom M. W. Nye, Cymon J. Cox & T. Martin Embley
Determining the relationships among the major groups of cellular life is important for understanding the evolution of biological diversity, but is difficult given the enormous time spans involved. In the textbook 'three domains' tree based on informational genes, eukaryotes and Archaea share a common ancestor to the exclusion of Bacteria. However, some phylogenetic analyses of the same data have placed eukaryotes within the Archaea, as the nearest relatives of different archaeal lineages. We compared the...

Estuarine fishes associated with intertidal oyster reefs characterised using environmental DNA and baited remote underwater video

Michael Stat
It has been widely shown that oyster reefs enhance local biodiversity and fisheries production. Therefore, in this study fish assemblages from oyster reefs were compared to sandy habitats using environmental DNA (eDNA) metabarcoding and baited remote underwater video. Fish diversity from eDNA was characterised using three metabarcoding assays - two that target the mitochondrial 16S region and one that targets the 12S region. Fish assemblages differed with each assay, as well as to that detected...

Data from: Microsatellite mutation rate in Atlantic sturgeon (Acipenser oxyrinchus)

Hanna Panagiotopoulou, James D. Austin, Katarzyna Zalewska, Magdalena Gonciarz, Kinga Czarnogórska, Jan Gawor, Piotr Weglenski & Danijela Popovic
Understanding mutation rates can greatly extend the utility of population and conservation genetic analyses. Herein we present an estimate of genome-wide microsatellite mutation rate in Atlantic sturgeon (Acipenser oxyrinchus) based on parent-offspring transmission patterns. We screened 307 individuals for parentage and mutation-rate analysis applying 43 variable markers. Out of 13,228 allele transfers, 11 mutations were detected, producing a mutation rate of 8.3x10-4 per locus per generation (95%CI: 1.48x10-3, 4.15x10-4). Single-step mutations predominated and there were...

Data from: Adult frogs and tadpoles have different macroevolutionary patterns across the Australian continent

Emma Sherratt, Marta Vidal-Garcia, Marion Anstis & J. Scott Keogh
Developmental changes through an animal’s life are generally understood to contribute to the resulting adult morphology. A possible exception are species with complex life cycles, where individuals pass through distinct ecological and morphological life stages during their ontogeny, ending with metamorphosis to the adult form. Antagonistic selection is expected to drive low genetic correlations between life stages, theoretically permitting stages to evolve independently. Using the Australian frog radiation, we examine the evolutionary consequences on morphological...

Environmental DNA can act as a biodiversity barometer of anthropogenic pressures in coastal ecosystems

Joseph DiBattista, James Reimer, Michael Stat, Giovanni Masucci, Piera Biondi, Maarten De Brauwer, Shaun Wilkinson, Anthony Chariton & Michael Bunce
Loss of biodiversity from lower to upper trophic levels reduces overall productivity and stability of coastal ecosystems in our oceans, but rarely are these changes documented across both time and space. The characterisation of environmental DNA (eDNA) from sediment and seawater using metabarcoding offers a powerful molecular lens to observe marine biota and provides a series of ‘snapshots’ across a broad spectrum of eukaryotic organisms. Using these next-generation tools and downstream analytical innovations including machine...

Large‐scale eDNA metabarcoding survey reveals marine biogeographic break and transitions over tropical north‐western Australia

Katrina West, Michael Travers, Michael Stat, Euan Harvey, Zoe Richards, Joseph DiBattista, Stephen Newman, Alastair Harry, Craig Skepper, Matthew Heydenrych, Michael Bunce, Michael J. Travers, Euan S. Harvey, Zoe T. Richards, Joseph D. DiBattista, Stephen J. Newman & Craig L. Skepper
Aim: Environmental DNA (eDNA) metabarcoding has demonstrated its applicability as a highly sensitive biomonitoring tool across small spatial and temporal scales in marine ecosystems. However, it has rarely been tested across large spatial scales, or biogeographical barriers. Here, we scale up marine eDNA metabarcoding, test its ability to detect a major marine biogeographic break, and evaluate its use as a regional biomonitoring tool in Australia. Location: North-western Australia (NWA) Methods: We applied metabarcoding assays targeting...

Data from: Coupling of diversification and pH adaptation during the evolution of terrestrial Thaumarchaeota

Cécile Gubry-Rangin, Christina Kratsch, Tom A. Williams, Alice C. McHardy, T. Martin Embley, James I. Prosser & Daniel J. Macqueen
The Thaumarchaeota is an abundant and ubiquitous phylum of archaea that plays a major role in the global nitrogen cycle. Previous analyses of the ammonia monooxygenase gene amoA suggest that pH is an important driver of niche specialization in these organisms. Although the ecological distribution and ecophysiology of extant Thaumarchaeota have been studied extensively, the evolutionary rise of these prokaryotes to ecological dominance in many habitats remains poorly understood. To characterize processes leading to their...

Data from: A global perspective on the trophic geography of sharks

Christopher Stephen Bird, Ana Veríssimo, Sarah Magozzi, Kátya G. Abrantes, Alex Aguilar, Hassan Al-Reasi, Adam Barnett, Dana M. Bethea, Gérard Biais, Asuncion Borrell, Marc Bouchoucha, Mariah Boyle, Edward J. Brooks, Juerg Brunnschweiler, Paco Bustamante, Aaron Carlisle, Diana Catarino, Stéphane Caut, Yves Cherel, Tiphaine Chouvelon, Diana Churchill, Javier Ciancio, Julien Claes, Ana Colaço, Dean L. Courtney … & Clive N. Trueman
Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits...

Data from: Two speed invasion: assisted and intrinsic dispersal of common mynas over 150-years of colonization

Kyle M. Ewart, Andrea S. Griffin, Rebecca N. Johnson, Salit Kark, Tali Magory Cohen, Nathan Lo & Richard E. Major
Aim: Despite the common myna’s widespread distribution, and the significant impact it has caused in parts of its non-native range, there have been no comprehensive genomic studies of its invasion of any region. We aimed to characterize the common myna invasion of the Australian continent to understand its population genetic landscape, introduction history, dispersal characteristics, and the interconnectedness between different source populations and invasive fronts. Location: Common mynas from 26 geographical locations spanning the Australian...

Data from: The remarkable convergence of skull shape in crocodilians and toothed whales

Matthew R. McCurry, Alistair R. Evans, Erich M.G. Fitzgerald, Justin W. Adams, Philip D. Clausen, Colin R. McHenry & Erich M. G. Fitzgerald
The striking resemblance of long-snouted aquatic mammals and reptiles has long been considered an example of morphological convergence, yet the true cause of this similarity remains untested. We addressed this deficit through three-dimensional morphometric analysis of the full diversity of crocodilian and toothed whale (Odontoceti) skull shapes. Our focus on biomechanically important aspects of shape allowed us to overcome difficulties involved in comparing mammals and reptiles, which have fundamental differences in the number and position...

Data from: Simple measures of climate, soil properties and plant traits predict national scale grassland soil carbon stocks

Peter Manning, Franciska T. De Vries, Jerry R. B. Tallowin, Roger Smith, Simon R. Mortimer, Emma S. Pilgrim, Kate A. Harrison, Daniel G. Wright, Helen Quirk, Joseph Benson, Bill Shipley, Johannes H. C. Cornelissen, Jens Kattge, Gerhard Bönisch, Christian Wirth & Richard D. Bardgett
1. Soil carbon (C) storage is a key ecosystem service. Soil C stocks play a vital role in soil fertility and climate regulation, but the factors that control these stocks at regional and national scales are unknown, particularly when their composition and stability are considered. As a result, their mapping relies on either unreliable proxy measures or laborious direct measurements. 2. Using data from an extensive national survey of English grasslands, we show that surface...

Data from: The behavioural response of migrating humpback whales to a full seismic air gun array

Rebecca A. Dunlop, Michael J. Noad, Robert D. McCauley, Eric Kniest, Robert Slade, David Paton & Douglas H. Cato
Despite concerns on the effects of noise from seismic survey air guns on marine organisms, there remains uncertainty in the biological significance of any response. This study quantifies and interprets the response of migrating humpback whales (Megaptera novaeangliae) to a 3130 cui (51.3l) commercial air gun array. We compare the behavioural responses to active trials (array operational; n = 34 whale groups), with responses to control trials (source vessel towing the array while silent; n...

Data from: Cytokine responses in birds challenged with the human food-borne pathogen Campylobacter jejuni implies a Th17 response

William D. K. Reid, Andrew J. Close, Suzanne Humphrey, Gemma Chaloner, Lizeth Lacharme-Lora, Lisa Rothwell, Pete Kaiser, Nicola J. Williams, Thomas J. Humprey, Paul Wigley, Stephen P. Rushton & Tom J. Humphrey
Development of process orientated understanding of cytokine interactions within the gastrointestinal tract during an immune response to pathogens requires experimentation and statistical modelling. The immune response against pathogen challenge depends on the specific threat to the host. Here, we show that broiler chickens mount a breed-dependent immune response to Campylobacter jejuni infection in the caeca by analysing experimental data using frequentist and Bayesian structural equation models (SEM). SEM provides a framework by which cytokine interdependencies,...

Data from: Tasting novel foods and selecting nutrient content in a highly successful ecological invader, the common myna

Chloe Peneaux, Gabriel E. Machovsky-Capuska, David Raubenheimer, Francoise Lermite, Charlotte Rousseau, Tanya Ruhan, John C. Rodger & Andrea S. Griffin
Invasion success is dependent on the ability of a species to discover and exploit novel food resources. Within this context, individuals must be willing to taste novel foods. They must also be capable of evaluating the nutritional content of new foods, and selecting their relative intake in order to fulfil their nutritional needs. Whereas the former capacity is well studied, little is known about the latter capacity. First, using the common myna as a model...

Data from: Systematic review: unmet supportive care needs in people diagnosed with chronic liver disease

Patricia C. Valery, Elizabeth Powell, Neta Moses, Michael Volk, Steven M. McPhail, Paul Clark & Jennifer Martin
Objective: People with chronic liver disease, particularly those with decompensated cirrhosis, experience several potentially debilitating complications that can have a significant impact on activities of daily living and quality of life. These impairments combined with the associated complex treatment mean that they are faced with specific and high levels of supportive care needs. We aimed to review reported perspectives, experiences and concerns of people with chronic liver disease worldwide. This information is necessary to guide...
