Data from: Progression of phosphine resistance in susceptible Tribolium castaneum (Herbst) populations under different immigration regimes and selection pressures

Michelle A. Rafter, Graham A. McCulloch, Greg J. Daglish, Gimme H. Walter & Gregory J. Daglish
Insecticide resistance is an escalating global issue for a wide variety of agriculturally important pests. The genetic basis and biochemical mechanisms of resistance are well characterised in some systems, but little is known about the ecological aspects of insecticide resistance. We therefore designed a laboratory experiment to quantify the progression of phosphine resistance in Tribolium castaneum populations subject to different immigration regimes and selection pressures. Mated resistant females were added to originally susceptible populations under...

Data from: Genomic clustering of adaptive loci during parallel evolution of an Australian wildflower

Federico Roda, Greg M. Walter, Rick Nipper & Daniel Ortiz-Barrientos
The buildup of the phenotypic differences that distinguish species has long intrigued biologists. These differences are often inherited as stable polymorphisms that allow the co-segregation of adaptive variation within species, and facilitate the differentiation of complex phenotypes between species. It has been suggested that the clustering of adaptive loci could facilitate this process but evidence is still scarce. Here we used QTL analysis to study the genetic basis of phenotypic differentiation between coastal populations of...

Data from: Tree mortality across biomes is promoted by drought intensity, lower wood density and higher specific leaf area

Sarah Greenwood, Paloma Ruiz-Benito, Jordi Martínez-Vilalta, Francisco Lloret, Thomas Kitzberger, Craig D. Allen, Rod Fensham, Daniel C. Laughlin, Jens Kattge, Gerhard Bonisch, Nathan J. B. Kraft & Alistair S. Jump
Drought events are increasing globally, and reports of consequent forest mortality are widespread. However, due to a lack of a quantitative global synthesis, it is still not clear whether drought-induced mortality rates differ among global biomes and whether functional traits influence the risk of drought-induced mortality. To address these uncertainties, we performed a global meta-analysis of 58 studies of drought-induced forest mortality. Mortality rates were modelled as a function of drought, temperature, biomes, phylogenetic and...

Data from: Transcriptome dynamics over a lunar month in a broadcast spawning Acroporid coral

Matthew J. Oldach, Matthew Workentine, Mikhail V. Matz, Tung-Yung Fan & Peter D. Vize
On one night per year, at a specific point in the lunar cycle, one of the most extraordinary reproductive events on the planet unfolds as hundreds of millions of broadcast spawning corals release their trillions of gametes into the waters of the tropical seas. Each species spawns on a specific night within the lunar cycle, typically from full moon to third quarter moon, and in a specific time window after sunset. This accuracy is essential...

Data from: Integrating phylogenetic and ecological distances reveals new insights into parasite host specificity

Nicholas J. Clark & Sonya M. Clegg
The range of hosts a pathogen infects (host specificity) is a key element of disease risk that may be influenced by both shared phylogenetic history and shared ecological attributes of prospective hosts. Phylospecificity indices quantify host specificity in terms of host relatedness, but can fail to capture ecological attributes that increase susceptibility. For instance, similarity in habitat niche may expose phylogenetically unrelated host species to similar pathogen assemblages. Using a recently proposed method that integrates...

Data from: Performance trade-offs and ageing in the ‘world's greatest athletes’

Vincent Careau & Robbie S. Wilson
The mechanistic foundations of performance trade-offs are clear: because body size and shape constrains movement, and muscles vary in strength and fibre type, certain physical traits should act in opposition with others (e.g. sprint versus endurance). Yet performance trade-offs are rarely detected, and traits are often positively correlated. A potential resolution to this conundrum is that within-individual performance trade-offs can be masked by among-individual variation in ‘quality’. Although there is a current debate on how...

Data from: Triggerfish uses chromaticity and lightness for object segregation

Karen L. Cheney, N. Justin Marshall, Fabio Cortesi, Laurie Mitchell & Misha Vorobyev
Humans group components of visual patterns according to their colour, and perceive colours separately from shape. This property of human visual perception is the basis behind the Ishihara test for colour deficiency, where an observer is asked to detect a pattern made up of dots of similar colour with variable lightness against a background of dots made from different colour(s) and lightness. To find out if fish use colour for object segregation in a similar...

Data from: Filters of floristic exchange: how traits and climate shape the rainforest invasion of Sahul from Sunda

Jia-Yee S. Yap, Maurizio Rossetto, Craig Costion, Darren Crayn, Robert M. Kooyman, James Richardson & Robert Henry
Aim To evaluate how biogeographic and ecological processes influenced species distributions and community assembly in a continental rainforest flora with mixed biogeographic origins. Location Continental Australia. Methods We identified 795 species with Sahul ancestry (Australian rainforest flora of Gondwanan origin) and 604 species with Sunda ancestry (rainforest plant lineages of Indo-Malesian origin) from a total of 1872 free-standing Australian woody rainforest taxa. We then compared the distribution of Sunda to Sahul species in relation to...

Data from: Temporally inter-comparable maps of terrestrial wilderness and the Last of the Wild

James Allan, Oscar Venter & James E. M. Watson
Wilderness areas, defined as areas free of industrial scale activities and other human pressures which result in significant biophysical disturbance, are important for biodiversity conservation and sustaining the key ecological processes underpinning planetary life-support systems. Despite their importance, wilderness areas are being rapidly eroded in extent and fragmented. Here we present the most up-to-date temporally inter-comparable maps of global terrestrial wilderness areas, which are essential for monitoring changes in their extent, and for proactively planning...

Data from: Skin sloughing in susceptible and resistant amphibians regulates infection with a fungal pathogen

Michel E. B. Ohmer, Rebecca L. Cramp, Catherine J. M. Russo, Craig R. White & Craig E. Franklin
The fungal pathogen Batrachochytrium dendrobatidis (Bd) has been implicated in amphibian population declines globally. Given that Bd infection is limited to the skin in post-metamorphic amphibians, routine skin sloughing may regulate infection. Skin sloughing has been shown to reduce the number of cultivatable microbes on amphibian skin, and Bd infection increases skin sloughing rates at high loads. However, it is unclear whether species specific differences in skin sloughing patterns could regulate Bd population growth on...

Data from: Optimizing the spatial planning of prescribed burns to achieve multiple objectives in a fire-dependent ecosystem.

Brooke A. Williams, Luke P. Shoo, Kerrie A. Wilson & Hawthorne L. Beyer
1. There is potential for negative consequences for the ecological integrity of fire-dependent ecosystems as a result of inappropriate fire regimes. This can occur when asset (property) protection is prioritised over conservation objectives in burn programs. 2. Optimisation of fire management for multiple objectives is rarely undertaken. Here, we use integer linear programming to identify burn scheduling solutions that will cost-effectively achieve asset protection and conservation objectives. 3. An approach to burn scheduling that favours...

Data from: How does mutation affect the distribution of phenotypes?

Katrina McGuigan & Ernest Aw
The potential for mutational processes to influence patterns of neutral or adaptive phenotypic evolution is not well understood. If mutations are directionally biased, shifting trait means in a particular direction, or if mutation generates more variance in some directions of multivariate trait space than others, mutation itself might be a source of bias in phenotypic evolution. Here, we use mutagenesis to investigate the affect of mutation on trait mean and (co)variances in zebrafish, Danio rerio....

Data from: Mitochondrial genomes of Australian chicken Eimeria support the presence of ten species with low genetic diversity among strains

Jess A. T. Morgan, Rosamond M. Godwin & Jess A.T. Morgan
Modern molecular approaches have vastly improved diagnostic capabilities for differentiating among species of chicken infecting Eimeria. Consolidating information from multiple genetic markers, adding additional poultry Eimeria species and increasing the size of available data-sets is improving the resolving power of the DNA, and consequently our understanding of the genus. This study adds information from 25 complete mitochondrial DNA genomes from Australian chicken Eimeria isolates representing all 10 species known to occur in Australia, including OTU-X,...

Data from: Environmental influences and ontogenetic differences in vertical habitat use of black marlin (Istiompax indica) in the southwestern Pacific

Samuel M. Williams, Bonnie J. Holmes, Sean R. Tracey, Julian G. Pepperell, Michael L. Domeier & Michael B. Bennett
The black marlin (Istiompax indica) is a highly migratory billfish that occupies waters throughout the tropical and subtropical Indo-Pacific. To characterize the vertical habitat use of I. indica, we examined the temperature-depth profiles collected using 102 pop-up satellite archival tags deployed off the east coast of Australia. Modelling of environmental variables revealed location, sea-surface height deviation, mixed layer depth and dissolved oxygen to all be significant predictors of vertical habitat use. Distinct differences in diel...

Data from: Investigating movement in the laboratory: dispersal apparatus designs and the red flour beetle, Tribolium castaneum

Pieter A. Arnold, Michelle A. Rafter, Rokhsareh Malekpour, Phillip Cassey, Gimme H. Walter & Craig R. White
The natural dispersal of Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) has been emulated in the laboratory for more than 50 years, using a simple dispersal apparatus. This has typically comprised of a starting container (initial resource or patch) connected by tubing, which contains thread for the animals to climb into a tube and hence to an end container. That is, beetles move to a new viable resource or patch from an inter-patch zone or non-viable habitat....

Data from: The palaeogenetics of cat dispersal in the ancient world

Claudio Ottoni, Wim Van Neer, Bea De Cupere, Julien Daligault, Silvia Guimaraes, Joris Peters, Nikolai Spassov, Mary E. Prendergast, Nicole Boivin, Arturo Morales-Muñiz, Adrian Bălăşescu, Cornelia Becker, Norbert Benecke, Adina Boroneant, Hijlke Buitenhuis, Jwana Chahoud, Alison Crowther, Laura Llorente, Nina Manaseryan, Hervé Monchot, Vedat Onart, Marta Osypińska, Olivier Putelat, Eréndira M. Quintana Morales, Jacqueline Studer … & Eva-Maria Geigl
The cat has long been important to human societies as a pest-control agent, object of symbolic value and companion animal, but little is known about its domestication process and early anthropogenic dispersal. Here we show, using ancient DNA analysis of geographically and temporally widespread archaeological cat remains, that both the Near Eastern and Egyptian populations of Felis silvestris lybica contributed to the gene pool of the domestic cat at different historical times. While the cat’s...

Data from: Archipelagos of the Anthropocene: rapid and extensive differentiation of native terrestrial vertebrates in a single metropolis

Bethan L. Littleford-Colquhoun, Christofer Clemente, Martin J. Whiting, Daniel Ortiz-Barrientos & Celine H. Frère
Some of the best evidence for rapid evolutionary change comes from studies of archipelagos and oceanic islands. City parks are analogous systems as they create geographically isolated green spaces that differ in size, structure, and complexity. Very little, however, is known about whether city parks in single urban centres drive selection and result in the diversification of native species. Here, we provide evidence for the rapid genetic and morphological differentiation of a native lizard (Intellagama...

Data from: The shape of success in a turbulent world: wave exposure filtering of coral reef herbivory

Sonia Bejarano, Jean-Baptiste Jouffray, Iliana Chollett, Robert Allen, George Roff, Alyssa Marshell, Robert Steneck, Sebastian C. A. Ferse & Peter J. Mumby
While environmental filters are well-known factors influencing community assembly, the extent to which these modify species functions, and entire ecosystem processes, is poorly understood. Focusing on a high-diversity system, we ask whether environmental filtering has ecosystem-wide effects beyond community assembly. We characterise a coral reef herbivorous fish community for swimming performance based on ten functional traits derived from fish morphology. We then investigate whether wave exposure modifies the functional make-up of herbivory, and the absolute...

Data from: Sexual selection on spontaneous mutations strengthens the between-sex genetic correlation for fitness

Scott Lee Allen, Katrina McGuigan, Tim Connallon, Mark W. Blows & Stephen F. Chenoweth
A proposed benefit to sexual selection is that it promotes purging of deleterious mutations from populations. For this benefit to be realised, sexual selection, which is usually stronger on males, must purge mutations deleterious to both sexes. Here, we experimentally test the hypothesis that sexual selection on males purges deleterious mutations that affect both male and female fitness. We measured male and female fitness in two panels of spontaneous mutation-accumulation lines of the fly, Drosophila...

Data from: Optimal running speeds when there is a trade-off between speed and the probability of mistakes

Ami Fadillah Amir Abdul Nasir, Christofer J. Clemente, Melissa L. Wynn, Robbie S. Wilson & Ami Fadhillah Amir Abdul Nasir
1. Do prey run as fast as they can to avoid capture? This is a common assumption in studies of animal performance, yet a recent mathematical model (Wheatley et al. 2015) of escape behaviour predicts that animals should instead use speeds below their maximum capabilities even when running from predators. Fast speeds may compromise motor control and accuracy of limb placement, particularly as the animal runs along narrow structures like beams or branches. Mistakes decrease...

Modelling seasonal habitat suitability for wide-ranging species: Invasive wild pigs in northern Australia

Jens G. Froese, Carl S. Smith, Peter A. Durr, Clive A. McAlpine & Rieks D. Van Klinken
Invasive wildlife often causes serious damage to the economy and agriculture as well as environmental, human and animal health. Habitat models can fill knowledge gaps about species distributions and assist planning to mitigate impacts. Yet, model accuracy and utility may be compromised by small study areas and limited integration of species ecology or temporal variability. Here we modelled seasonal habitat suitability for wild pigs, a widespread and harmful invader, in northern Australia. We developed a...

Data from: Identifying patterns and drivers of coral diversity in the Central Indo-Pacific marine biodiversity hotspot

Morana Mihaljević, Chelsea Korpanty, Willem Renema, Kevin Welsh & John M. Pandolfi
Biodiversity hotspots are increasingly recognized as areas of high taxonomic and functional diversity. These hotspots are dynamic and shift geographically over time in response to environmental change. To identify drivers of the origin, evolution, and persistence of diversity hotspots, we investigated the diversity patterns of reef-building corals (Scleractinia) in the Central Indo-Pacific, a marine biodiversity hotspot for the last 25 Myr. We used the scleractinian fossil record (based on literature and a newly acquired fossil...

Data from: Pushing the limits of photoreception in twilight conditions: The rod-like cone retina of the deep-sea pearlsides

Fanny De Busserolles, Fabio Cortesi, Jon Vidar Helvik, Wayne I. L. Davies, Rachel M. Templin, Robert K. P. Sullivan, Craig T. Michell, Jessica K. Mountford, Shaun P. Collin, Xabier Irigoien, Stein Kaartvedt & Justin Marshall
Most vertebrates have a duplex retina comprising two photoreceptor types, rods for dim-light (scotopic) vision and cones for bright-light (photopic) and color vision. However, deep-sea fishes are only active in dim-light conditions; hence, most species have lost their cones in favor of a simplex retina composed exclusively of rods. Although the pearlsides, Maurolicus spp., have such a pure rod retina, their behavior is at odds with this simplex visual system. Contrary to other deep-sea fishes,...

Data from: Skill not athleticism predicts individual variation in match performance of soccer players

Robbie S. Wilson, Gwendolyn K. David, Sean C. Murphy, , Amanda C. Niehaus, Andrew H. Hunter, Michelle D. Smith & Michael J. Angilletta
Just as evolutionary biologists endeavor to link phenotypes to fitness, sport scientists try to identify traits that determine athlete success. Both disciplines would benefit from collaboration, and to illustrate this, we used an analytical approach common to evolutionary biology to isolate the phenotypes that promote success in soccer, a complex activity of humans played in nearly every modern society. Using path analysis, we quantified the relationships among morphology, balance, skill, athleticism, and performance of soccer...

Data from: Interacting livestock and fire may both threaten and increase viability of a fire-adapted Mediterranean carnivorous plant

Maria Paniw, Pedro F. Quintana-Ascencio, Fernando Ojeda & Roberto Salguero-Gomez
1. Quantifying interactive effects of environmental drivers on population dynamics can be critical for a robust analysis of population viability. Fire regimes, among the most widespread disturbances driving population dynamics, are increasingly modified by and interact with human activities. However, viability of fire-adapted species is typically assessed overlooking disturbance interactions, potentially resulting in suboptimal management actions. 2. We investigated whether increasing human disturbances in fire-prone ecosystems may pose a threat or an opportunity to improve...
