Unpaired super-resolution on micro-CT sandstone by using cycle-consistent generative adversarial network

Yufu Niu, Ryan Armstrong & Peyman Mostaghimi
High-resolution X-ray micro-computed tomography (CT) data is required for accurate determination of rock petrophysical properties. High-resolution data, however, results in small field-of-view, thus the representativeness of simulation domain can be brought into question for geophysical applications. This project aims to develop new techniques for super resolution in digital rock.

Included with the photographic images are the coordinates of ground control markers, biomass, taxonomic and location data for harvest plots and ancillary metadata. The observations can be used to obtain allometric size-biomass models. This work was supported by the Natural Environment Research Council award...

Bentheimer Sandstone for Analyzing Wetting Phenomena

Chenhao Sun, James McClure, Peyman Mostaghimi, Anna Herring, Steffen Berg & Ryan Armstrong
The micro-CT image data of Bentheimer sandstone used in characterizing its wettability. The primary drainage and imbibition experiments were performed by using air and brine. The images were acquired at irreducible air saturation Sw=94%. This dataset is used to characterize wetting in complex subsurface multiphase systems by using principles of topology and integral geometry.

Data from: Surface-water dynamics and land use influence landscape connectivity across a major dryland region

Robbi Bishop-Taylor, Mirela G. Tulbure & Mark Broich
Landscape connectivity is important for the long-term persistence of species inhabiting dryland freshwater ecosystems, with spatiotemporal surface-water dynamics (e.g., flooding) maintaining connectivity by both creating temporary habitats and providing transient opportunities for dispersal. Improving our understanding of how landscape connectivity varies with respect to surface-water dynamics and land use is an important step to maintaining biodiversity in dynamic dryland environments. Using a newly available validated Landsat TM and ETM+ surface-water time series, we modelled landscape...

Data from: Seagrass on the brink: decline of threatened seagrass Posidonia australis continues following protection

Suzanna M. Evans, Kingsley J. Griffin, Ray A. J. Blick, Alistair G. B. Poore & Adriana Verges
Seagrasses are in decline globally due to sustained pressure from coastal development, water quality declines and the ongoing threat from climate change. The result of this decline has been a loss of coastal productivity, a reduction in critical fisheries habitat and increased erosion. Attempts to slow this decline have included legislative protection of habitat and direct restoration efforts. Monitoring the success of these approaches requires tracking changes in the abundance of seagrasses, but such monitoring...

Data from: Maternal effects impact decision-making in a viviparous lizard

Kirke L. Munch, Daniel W.A. Noble, Thomas Botterill-James, Iain S. Koolhof, Ben Halliwell, Erik Wapstra, Geoffrey M. While & Daniel W. A. Noble
Stressful conditions experienced during early development can have deleterious effects on offspring morphology, physiology and behaviour. However, few studies have examined how developmental stress influences an individual’s cognitive phenotype. Using a viviparous lizard, we show that the availability of food resources to a mother during gestation influences a key component of her offspring’s cognitive phenotype; their decision-making. Offspring from females who experienced low resource availability during gestation did better in an anti-predatory task that relied...

Data from: Impact of cane toads on a community of Australian native frogs, determined by 10 years of automated identification and logging of calling behaviour

Andrew Taylor, Hamish I. McCallum, Graeme Watson & Gordon C. Grigg
Invasive species may have devastating impacts on native biota. Cane toads Rhinella marina continue to invade northern Australia and the consequences for the endemic frogs are unclear. Monitoring frogs in such remote areas is difficult because their activity depends heavily on unpredictable rainfall events. We developed an autonomous acoustic monitoring system which used machine learning techniques to identify up to 22 calling species in real time. Ten of these systems, capable of operating for at...

Data from: Manipulation of habitat isolation and area implicates deterministic factors and limited neutrality in community assembly

Terry J. Ord, Jack Emblen, Mattias Hagman, Ryan Shofner & Sara Unruh
Theory predicts deterministic and stochastic factors will contribute to community assembly in different ways: environmental filters should regulate those species that establish in a particular area resulting in the ecological requirements of species being the primary driver of species distributions, while chance and dispersal limitation should dictate the likelihood of species reaching certain areas with the ecology of species being largely neutral. These factors are specifically relevant for understanding how the area and isolation of...

Data from: Key innovations and island colonization as engines of evolutionary diversification: a comparative test with the Australasian diplodactyloid geckos

Joan Garcia-Porta & Terry J. Ord
The acquisition of key innovations and the invasion of new areas constitute two major processes that facilitate ecological opportunity and subsequent evolutionary diversification. Using a major lizard radiation as a model, the Australasian diplodactyloid geckos, we explored the effects of two key innovations (adhesive toepads and a snake-like phenotype) and the invasion of new environments (island colonization) in promoting the evolution of phenotypic and species diversity. We found no evidence that toepads had significantly increased...

Data from: Spatiotemporal dynamic of surface water bodies using Landsat time-series data from 1999 to 2011

Mirela G. Tulbure & Mark Broich
Detailed information on the spatiotemporal dynamic in surface water bodies is important for quantifying the effects of a drying climate, increased water abstraction and rapid urbanization on wetlands. The Swan Coastal Plain (SCP) with over 1500 wetlands is a global biodiversity hotspot located in the southwest of Western Australia, where more than 70% of the wetlands have been lost since European settlement. SCP is located in an area affected by recent climate change that also...

Data from: Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces

Mikhail V. Kozlov, Huajian Cai, Jorge Contreras-Garduño, Barnaby J. Dixson, Gavita A. Oana, Gwenaël Kaminski, Norman P. Li, Minna T. Lyons, Ike E. Onyishi, Keshav Prasai, Farid Pazhoohi, Pavol Prokop, Sandra L. Rosales Cardozo, Nicolle Sydney, Jose C. Yong, Markus J. Rantala, U. M. Marcinkowska & J. Contreras-Garduno
Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men's preference for femininity in women's faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of men's preferences. Using an average femininity preference for each country, we found men's facial femininity preferences correlated positively with the...

Data from: Bat communities respond positively to large-scale thinning of forest regrowth

Rachel V. Blakey, Brad S. Law, Richard T. Kingsford, Jakub Stoklosa, Patrick Tap & Kelly Williamson
Over half of the world's forests are secondary regrowth and support considerable biodiversity. Thinning of these forests is a widespread management practice that can affect forest species, including echolocating bats and their prey. We compared total activity of 11 bat taxa, foraging activity of six bat guilds and biomass of 11 insect orders across four forest thinning categories in managed remnant eucalypt forests in south-eastern Australia: unthinned regrowth, forest thinned recently (0–4 years) and in...

Data from: Effects of condition and sperm competition risk on sperm allocation and storage in neriid flies

Zac Wylde, Angela Crean & Russell Bonduriansky
Ejaculate traits can be sexually selected and often exhibit heightened condition-dependence. However, the influence of sperm competition risk in tandem with condition-dependent ejaculate allocation strategies is relatively unstudied. Because ejaculates are costly to produce, high-condition males may be expected to invest more in ejaculates when sperm competition risk is greater. We examined the condition-dependence of ejaculate size by manipulating nutrient concentration in the juvenile (larval) diet of the neriid fly Telostylinus angusticollis. Using a fully...

Data from: High-content imaging of unbiased chemical perturbations reveals that the phenotypic plasticity of the actin cytoskeleton is constrained

Nicole S. Bryce, Tim W. Failes, Justine R. Stehn, Karen Baker, Stefan Zahler, Yulia Arzhaeva, Leanne Bischof, Lyons Ciaran, Irina Dedova, Greg M. Arndt, Katharina Gaus, Benjamin T. Goult, Edna C. Hardeman, Peter W Gunning & John G. Lock
Although F-actin has a large number of binding partners and regulators, the number of phenotypic states available to the actin cytoskeleton is unknown. Here, we quantified 74 features defining F-actin and cellular morphology in >25 million cells after treatment with a library of 114,400 structurally diverse compounds. After reducing the dimensionality of these data, we found that only ~25 recurrent F-actin phenotypes emerged, each defined by distinct quantitative features that could be machine learned. We...

Data from: Modes of berm and beachface recovery following storm reset: observations using a continuously scanning lidar

Matthew S. Phillips, Chris E. Blenkinsopp, Kristen D. Splinter, Mitchell D. Harley & Ian L. Turner
Following the rapid and destructive impacts of storm erosion, beach recovery is a key natural process of restoration, returning eroded sediment to the subaerial beach and rebuilding coastal morphology. While the effects of storm erosion have commonly been investigated, detailed studies into post-storm recovery are currently lacking. This study investigates wave-driven recovery processes of the berm and beachface on a microtidal, swash-aligned sandy beach. Following complete removal of the berm by a significant storm event,...

Data from: Plant traits of propagule banks and standing vegetation reveal flooding alleviates impacts of agriculture on wetland restoration

Samantha K. Dawson, David I. Warton, Richard T. Kingsford, Peter Berney, David A. Keith & Jane A. Catford
1. Restoration of degraded plant communities requires understanding of community assembly processes. Human land use can influence plant community assembly by altering environmental conditions and species’ dispersal patterns. Flooding, including from environmental flows, may counteract land use effects on wetland vegetation. We examined the influence of land use history and flood frequency on the functional composition of wetland plant communities along a regulated river. 2. We applied fourth corner modelling to determine species’ trait-based responses...

Data from: Zoogeographical regions and geospatial patterns of phylogenetic diversity and endemism of New World bats

Camilo López-Aguirre, Suzanne J. Hand, Shawn W. Laffan & Michael Archer
The analysis of regional scale patterns of diversity allows insights into the processes that have shaped modern biodiversity at the macro‐scale. Previous analyses studying biogeographic regionalisation across different high‐level taxa have shown similar trends at a global scale. However, incorporating phylogenetic methods when comparing biogeographic regionalisation between subgroups facilitates identification of mechanisms leading to the biogeographic distribution of specific taxa. We analysed the spatial trends of phylogenetic diversity and phylogenetic endemism of 325 species of...

Data from: The emergence of the lobsters: phylogenetic relationships, morphological evolution and divergence time comparisons of an ancient group (Decapoda: Achelata, Astacidea, Glypheidea, Polychelida)

Heather D. Bracken-Grissom, Shane T. Ahyong, Richard D. Wilkinson, Rodney M. Felmann, Carrie E. Schweitzer, Jesse W. Breinholt, Matthew Bendall, Ferran Palero, Tin-Yam Chan, Darryl L. Felder, Rafael Robles, Ka-Hou Chu, Ling-Ming Tsang, Dohyup Kim, Joel W. Martin, Keith A. Crandall & Rodney M. Feldmann
Lobsters are a ubiquitous and economically important group of decapod crustaceans that includes the infraorders Polychelida, Glypheidea, Astacidea and Achelata. They include familiar forms such as the spiny, slipper, clawed lobsters and crayfish and unfamiliar forms such as the deep-sea and “living fossil” species. The high degree of morphological diversity among these infraorders has led to a dynamic classification and conflicting hypotheses of evolutionary relationships. In this study, we estimated phylogenetic relationships amongst the major...

Data from: Removal of an apex predator initiates a trophic cascade that extends from herbivores to vegetation and the soil nutrient pool

Timothy Morris & Mike Letnic
It is widely assumed that organisms at low trophic levels, particularly microbes and plants, are essential to basic services in ecosystems, such as nutrient cycling. In theory, apex predators' effects on ecosystems could extend to nutrient cycling and the soil nutrient pool by influencing the intensity and spatial organization of herbivory. Here, we take advantage of a long-term manipulation of dingo abundance across Australia's dingo-proof fence in the Strzelecki Desert to investigate the effects that...

Data from: Isolation rearing does not constrain social plasticity in a family-living lizard

Julia L. Riley, Côme Guidou, Caroline Fryns, Johann Mourier, Stephan T. Leu, Daniel W.A. Noble, Richard W. Byrne, Martin J. Whiting & Daniel W A Noble
An animal’s social environment can be both dynamic and complex. Thus, social species often garner fitness benefits through being plastic in their social behavior. Yet, social plasticity can be constrained by an individual’s experience. We examined the influence of early social environment on social behavior in the tree skink (Egernia striolata), a family-living lizard. In the first phase of this study, we reared juveniles in two different social environments for 1.5 years: either in isolation...

Data from: Functional extinction of a desert rodent: implications for seed fate and vegetation dynamics

Christopher E. Gordon & Mike Letnic
Population declines of once-abundant species have often preceded understanding of their roles within ecosystems. Consequently, important drivers of environmental change may remain undiagnosed because we simply do not know how species that are now rare or extinct shaped ecosystems in the past. Australia's desert rodents are thought to have little numerical impact on seed fate and vegetation recruitment when compared with ants or with desert rodents on other continents. However most research on granivory by...

Data from: Identification of allosteric disulphides from labile bonds in X-ray structures

Aster E. Pijning, Joyce Chiu, Reichelle X. Yeo, Jason W. H. Wong & Philip J. Hogg
Protein disulfide bonds link pairs of cysteine sulfur atoms and are either structural or functional motifs. The allosteric disulfides control the function of the protein in which they reside when cleaved or formed. Here, we identify potential allosteric disulfides in all Protein Data Bank X-ray structures from bonds that are present in some molecules of a protein crystal but absent in others, or present in some structures of a protein but absent in others. We...

Data from: Palaeoecological inferences for the fossil Australian snakes Yurlunggur and Wonambi (Serpentes, Madtsoiidae)

Alessandro Palci, Mark N. Hutchinson, Michael W. Caldwell, John D. Scanlon, Michael S.Y. Lee & Michael S. Y. Lee
Madtsoiids are among the most basal snakes, with a fossil record dating back to the Upper Cretaceous (Cenomanian). Most representatives went extinct by the end of the Eocene, but some survived in Australia until the late Cenozoic. Yurlunggur and Wonambi are two of these late forms, and also the best-known madtsoiids to date. A better understanding of the anatomy and palaeoecology of these taxa may shed light on the evolution and extinction of this poorly...

Data from: Cross-validation strategies for data with temporal, spatial, hierarchical, or phylogenetic structure

David R. Roberts, Volker Bahn, Simone Ciuti, Mark S. Boyce, Jane Elith, Gurutzeta Guillera-Arroita, Severin Hauenstein, José J. Lahoz-Monfort, Boris Schröder, Wilfried Thuiller, David I. Warton, Brendan A. Wintle, Florian Hartig & Carsten F. Dormann
Ecological data often show temporal, spatial, hierarchical (random effects), or phylogenetic structure. Modern statistical approaches are increasingly accounting for such dependencies. However, when performing cross-validation, these structures are regularly ignored, resulting in serious underestimation of predictive error. One cause for the poor performance of uncorrected (random) cross-validation, noted often by modellers, are dependence structures in the data that persist as dependence structures in model residuals, violating the assumption of independence. Even more concerning, because often...

Data from: Historical contingency and behavioural divergence in territorial Anolis lizards

Terry J. Ord
The extent that evolution—including adaptation—is historically contingent (dependent on past events) has often been hotly debated, but is still poorly understood. In particular, there is little data on the degree that behaviour, an aspect of the phenotype that is strongly linked to contemporary environments (social or physical), retains the imprint of evolutionary history. In this study, I examined whether differences in the design of the territorial displays among species of Caribbean Anolis lizards reflect island...
