Data from: The evolution of ontogenetic allometric trajectories in mammalian domestication

Laura A. B. Wilson
Morphological divergence of domesticated as compared to wild forms must result from changes in the ontogenetic process. Species-specific tests for heterochrony have rejected a single explanation of domestic forms representing juveniles of their wild relatives. Ontogenetic allometric trajectories for 12 pairs of wild and domestic mammals were examined using skull growth data for 1070 specimens, including representatives from all lineages in which domestication has occurred. A suite of tests were performed to quantify allometric disparity...

Data from: Phylogenetic diversity, types of endemism and the evolutionary history of New World bats

Camilo López-Aguirre, Suzanne J. Hand, Shawn W. Laffan & Michael Archer
New World bats represent over one third of global bat species and encompass the widest adaptive radiation among bats. Modern bat diversity in the Americas resulted from a mixture of migrations and colonisations of different taxa throughout the Cenozoic. Traditionally, these taxa are conceived as either South or North American, based on the location of their centres of diversification. To better understand the spatial and temporal processes behind modern biogeographic patterns of New World bat...

Data from: Changes in desert avifauna associated with the functional extinction of a terrestrial top predator

James D. Rees, Richard T. Kingsford & Mike Letnic
We investigated how long-term suppression of populations of a top predator, the dingo Canis dingo, affected composition of sympatric avifauna in Australian deserts, by surveying bird assemblages across ~80 000 km2 of arid dunefields on either side of the Dingo Barrier Fence (DBF; a 5,614 km-long fence separating ecosystems in which dingoes are abundant from ecosystems in which dingoes are functionally extinct). Using fourth-corner modelling, incorporating species’ traits, we identified apparent declines of sedentary birds...

Data from: Near-infrared spectroscopy for metabolite quantification and species identification

Wen Chyuan Aw & J. William Ballard
Near-infrared spectroscopy (NIRS) is a high-throughput method to analyse the near-infrared region of the electromagnetic spectrum. It detects the absorption of light by molecular bonds and can be used with live insects. In this study, we investigate the accuracy of NIRS in determining triglyceride level and species of wild caught Drosophila. We employ the chemometric approach to produce a multivariate calibration model. The multivariate calibration model is the mathematical relationship between the changes in NIR...

Data from: Functional heterogeneity within the rodent lateral orbitofrontal cortex dissociates outcome devaluation and reversal learning deficits

Marios C Panayi & Simon Killcross
The orbitofrontal cortex (OFC) is critical for updating reward-directed behaviours flexibly when outcomes are devalued or when task contingencies are reversed. Failure to update behaviour in outcome devaluation and reversal learning procedures are considered canonical deficits following OFC lesions in non-human primates and rodents. We examined the generality of these findings in rodents using lesions of the rodent lateral OFC (LO) in instrumental action-outcome and Pavlovian cue-outcome devaluation procedures. LO lesions disrupted outcome devaluation in...

Data from: Detection of persistent signals and its relation to coherent feedforward loops

Chun Tung Chou
Many studies have shown that cells use temporal dynamics of signalling molecules to encode information. One particular class of temporal dynamics is persistent and transient signals, i.e. signals of long and short durations respectively. It has been shown that the coherent type-1 feedforward loop with an AND logic at the output (or C1-FFL for short) can be used to discriminate a persistent input signal from a transient one. This has been done by modelling the...

Data from: The role of red coloration and song in peacock spiders: insights into complex signaling systems

Madeline B. Girard, Michael M. Kasumovic & Damian O. Elias
Research on animal signaling enhances our understanding of links between sensory processing, decision-making, behavior, and evolution. Studies of sexually-selected signals may be particularly informative as mate choice provides access to decision patterns in the way that courtship leads to an easily observable behavioral output in choosers, i.e. mating. Male peacock spiders have some of the most elaborate and varied courtship displays known among animals. Particularly striking to human observers is the diversity of red, orange...

Data from: Multiple biological mechanisms result in correlations between pre- and post-mating traits that differ among versus within individuals and genotypes

Cristina Tuni, Chang S. Han & Niels J. Dingemanse
Reproductive traits involved in mate acquisition (pre-mating traits) are predicted to covary with those involved in fertilization success (post-mating traits). Variation in male quality may give rise to positive, and resource allocation trade-offs to negative, covariances between pre- and post-mating traits. Empirical studies have yielded mixed results. Progress is hampered as researchers often fail to appreciate that mentioned biological mechanisms can act simultaneously but at different hierarchical levels of biological variation: genetic correlations may, for...

Data from: Elucidating biogeographical patterns in Australian native canids using genome wide SNPs

Kylie M. Cairns, Laura M. Shannon, Janice Koler-Matznick, J. William O. Ballard & Adam R. Boyko
Dingoes play a strong role in Australia’s ecological framework as the apex predator but are under threat from hybridization and agricultural control programs. Government legislation lists the conservation of the dingo as an important aim, yet little is known about the biogeography of this enigmatic canine, making conservation difficult. Mitochondrial and Y chromosome DNA studies show evidence of population structure within the dingo. Here, we present the data from Illumina HD canine chip genotyping for...

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: Latitudinal variation in seagrass herbivory: global patterns and explanatory mechanisms

Adriana Vergés, Christopher Doropoulos, Rob Czarnik, Kathryn McMahon, Nil Llonch & Alistair G. B. Poore
Aim: The aim was to quantify latitudinal patterns in seagrass–herbivore interactions in the context of a warming climate. Location: We carried out a global meta‐analysis combined with a field experiment across 1,700 km and 12° of latitude in Western Australia. Time period: 1984–2014. Major taxa studied: Seagrasses. Methods: We first synthesized the global literature on herbivore exclusion experiments in seagrasses to test whether differences in herbivore impacts are related to latitude and sea surface temperature....

Data from: Primary productivity is related to niche width in the Australian Wet Tropics

Hugh M. Burley, Karel Mokany, Shawn W. Laffan, Kristen J. Williams, Dan Metcalfe, Helen T. Murphy, Andrew Ford, Tom D. Harwood & Simon Ferrier
Aim: A key ecological debate is whether ecosystem functions are distinctly influenced by biological diversity across broad scales. Although recent work has emphasized the importance of links between ecosystem functions and measures of ecological specialization as proxies of biodiversity, few studies have analysed macroecological relationships empirically in diverse environments. We tested whether gross primary productivity (GPP) in the Australian Wet Tropics (WT) was distinctly related to community‐level measures of the ecological specialization of component tree...

Data from: Maternal presence facilitates plasticity in offspring behavior: insights into the evolution of parental care

Kirke L. Munch, Daniel W.A. Noble, Luke Budd, Aryana Row, Erik Wapstra, Geoffrey M. While & Daniel W A Noble
Fundamental to the definition of parental care is that care confers benefits to the offspring. However, the mechanisms resulting in these benefits remain poorly understood, particularly in species where postnatal care is not obligatory. Here, we address this shortcoming using a lizard, Liopholis whitii, in which family life is facultative and relatively simple – extending to prolonged associations between parents and offspring within the parental territory. Using a split-clutch design, we housed offspring either with...

Data from: Recent grazing reduces reptile richness but historic grazing filters reptiles based on their functional traits

James Val, Samantha K. Travers, Ian Oliver, Terry B. Koen & David J. Eldridge
1. Grazing by mammalian herbivores can alter vegetation structure and composition. It can therefore affect critical habitat features used by native wildlife for shelter, feeding and breeding. This can have variable effects, which advantage or disadvantage particular species, depending on habitat requirements. 2. We tested the relative effects of recent and historic livestock grazing and recent rabbit and kangaroo grazing on all reptiles, and on specific groups of reptiles based on three functional traits: habitat...

Data from: Reversing functional extinction of mammals prompts a rethink of paradigms about seed fate in arid Australia

Charlotte Mills, Mike Letnic & Charlotte H. Mills
Functional extinction of once abundant species has frequently preceded understanding of their ecological roles. Consequently, our understanding of ecosystems is prone to shifting baselines because it often relies on observations made on depauperate species assemblages. In Australian deserts, current paradigms are that ants are the dominant granivores, mammals are unimportant seed predators and that myrmecochory in many Australian shrubs is an adaptation to increase dispersal distance and direct seeds to favourable germination sites. Here, we...

Data from: Apex predator suppression is linked to restructuring of ecosystems via multiple ecological pathways

Viyanna Leo, Richard P. Reading, Christopher Gordon & Mike Letnic
Removal of apex predators can drive ecological regime shifts owing to compensatory positive and negative population level responses by organisms at lower trophic levels. Despite evidence that apex predators can influence ecosystems though multiple ecological pathways, most studies investigating apex predators’ effects on ecosystems have considered just one pathway in isolation. Here, we provide evidence that lethal control of an apex predator, the dingo (Canis dingo), drives shifts in the structure of Australia’s tropical-savannah ecosystems....

Data from: Web building and silk properties functionally covary among species of wolf spider

Mariángeles Lacava, Arley Camargo, Luiz F. Garcia, Martin Santana, Jian Fang, Xungai Wang & Sean J. Blamires
While phylogenetic studies have shown covariation between the properties of spider major ampullate (MA) silk and web building, both spider webs and silks are highly plastic so we cannot be sure whether these traits functionally co-vary or just vary across environments that the spiders occupy. Since MaSp2-like proteins provide MA silk with greater extensibility, their presence is considered necessary for spider webs to effectively capture prey. Wolf spiders (Lycosidae) are predominantly non-web building, but a...

Data from: Host diet mediates a negative relationship between abundance and diversity of Drosophila gut microbiota

Berra Erkosar, Erika Yashiro, Felix Zajitschek, Urban Friberg, Alexei A. Maklakov, Jan Roelof Van Der Meer & Tadeusz J. Kawecki
Nutrient supply to ecosystems has major effects on ecological diversity, but it is unclear to what degree the shape of this relationship is general versus dependent on the specific environment or community. Although the diet composition in terms of the source or proportions of different nutrient types is known to affect gut microbiota composition, the relationship between the quantity of nutrients supplied and the abundance and diversity of the intestinal microbial community remains to be...

Data from: Developmental diet irreversibly shapes male post-copulatory traits in the neriid fly (Telostylinus angusticollis)

Erin L. Macartney, Philip R. Nicovich, Russell Bonduriansky & Angela J. Crean
Nutrient availability has been shown to influence investment in many fitness related traits, including male reproductive success. Many studies have demonstrated that a reduction in nutrient availability alters male post-copulatory trait expression, with some studies demonstrating an effect of developmental nutrients and others, an effect of adult nutrients. However, few studies have manipulated both developmental and adult nutrients in the same experiment. Therefore, it is not clear what life-stage has the greatest effect on post-copulatory...

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: 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: 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: 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...
