Data from: Transcriptomic differences between day and night in Acropora millepora provide new insights into metabolite exchange and light-enhanced calcification in corals

Anthony Bertucci, Sylvain Forêt, Eldon E. Ball & David J. Miller
The evolutionary success of reef-building corals is often attributed to their symbiotic relationship with photosynthetic dinoflagellates of the genus Symbiodinium, but metabolic interactions between the partners and the molecular bases of light-enhanced calcification (LEC) are not well understood. Here, the metabolic bases of the interaction between the coral Acropora millepora and its dinoflagellate symbiont were investigated by comparing gene expression levels under light and dark conditions at the whole transcriptome level. Among the 497 differentially...

Data from: Avian functional responses to landscape recovery

Karen Ikin, Philip S. Barton, Wade Blanchard, Mason Crane, John Stein & David B. Lindenmayer
Restoring native vegetation in agricultural landscapes can reverse biodiversity declines via species gains. Depending on whether the traits of colonizers are complementary or redundant to the assemblage, species gains can increase the efficiency or stability of ecological functions, yet detecting these processes is not straightforward. We propose a new conceptual model to identify potential changes to complementarity and redundancy in response to landscape change via relative changes in taxonomic and functional richness. We applied our...

Data from: Rhytiphora: a phylogenetic and morphological study of Australia’s largest longhorn beetle genus

Lauren Ashman, Diana Hartley, Mengjie Jin, David Rowell, Luisa Teasdale, Adam Slipinski & Andreas Zwick
Rhytiphora Audinet-Serville is the most speciose longhorn beetle (Cerambycidae) genus in Australia, with about 200 species (from nearly 40 former genera, now synonymised into one) distributed across the entire continent. We used mitochondrial genome data from whole genome shotgun sequencing and COI barcoding of museum specimens to reconstruct the phylogeny of 68 Rhytiphora species, and analyse their morphological diversity and biogeographic history. We recovered a monophyletic Rhytiphora containing two distinct clades, within which all of...

Data from: Covariation in life-history traits: differential effects of diet on condition, hormones, behavior and reproduction in genetic finch morphs

Sarah R. Pryke, Lee B. Astheimer, Simon C. Griffith & William A. Buttemer
The relative contribution of genetic and environmental factors in determining variation in life-history traits is of central interest to evolutionary biologists, but the physiological mechanisms underlying these traits are still poorly understood. Here we experimentally demonstrate opposing effects of nutritional stress on immune function, endocrine physiology, parental care and reproduction between red and black head-color morphs of the Gouldian finch (Erythrura gouldiae). Although body condition of black morphs was largely unaffected by diet manipulation, red...

Data from: Testing the impact of calibration on molecular divergence times using a fossil-rich group: the case of Nothofagus (Fagales)

Hervé Sauquet, Simon Y. W. Ho, Maria A. Gandolfo, Gregory J. Jordan, Peter Wilf, David J. Cantrill, Michael J. Bayly, Lindell Bromham, Gillian K. Brown, Raymond J. Carpenter, Daphne M. Lee, Daniel J. Murphy, J. M. Kale Sniderman & Frank Udovicic
Although temporal calibration is widely recognized as critical for obtaining accurate divergence-time estimates using molecular dating methods, few studies have evaluated the variation resulting from different calibration strategies. Depending on the information available, researchers have often used primary calibrations from the fossil record or secondary calibrations from previous molecular dating studies. In analyses of flowering plants, primary calibration data can be obtained from macro- and mesofossils (e.g., leaves, flowers, and fruits) or microfossils (e.g., pollen)....

Data from: Negative frequency-dependent selection of sexually antagonistic alleles in Myodes glareolus

Mikael Mokkonen, Hanna Kokko, Esa Koskela, Jussi Lehtonen, Tapio Mappes, Henna Martiskainen & Suzanne C. Mills
Sexually antagonistic genetic variation, where optimal values of traits are sex-dependent, is known to slow the loss of genetic variance associated with directional selection on fitness-related traits. However, sexual antagonism alone is not sufficient to maintain variation indefinitely. Selection of rare forms within the sexes can help to conserve genotypic diversity. We combined theoretical models and a field experiment with Myodes glareolus to show that negative frequency-dependent selection on male dominance maintains variation in sexually...

Data from: Using probability modelling and genetic parentage assignment to test the role of local mate availability in mating system variation.

Michaela D J Blyton, Sam C Banks, Rod Peakall & David B Lindenmayer
The formal testing of mating system theories with empirical data is important for evaluating the relative importance of different processes in shaping mating systems in wild populations. Here we present a generally applicable probability modelling framework to test the role of local mate availability in determining a population’s level of genetic monogamy. We provide a significance test for detecting departures in observed mating patterns from model expectations based on mate availability alone, allowing the presence...

Data from: Strategic promiscuity helps avoid inbreeding at multiple levels in a cooperative breeder where both sexes are philopatric

Lyanne Brouwer, Martijn Van De Pol, Els Atema & Andrew Cockburn
In cooperative breeders the tension between the opposing forces of kin-selection and kin-competition is at its most severe. Although philopatry facilitates kin-selection, it also increases the risk of inbreeding. When dispersal is limited, extra-pair paternity might be an important mechanism to avoid inbreeding, but evidence for this is equivocal. The red-winged fairy-wren is part of a genus of cooperative breeders with extreme levels of promiscuity and male philopatry, but is unique in that females are...

Data from: The local-clock permutation test: a simple test to compare rates of molecular evolution on phylogenetic trees

Robert Lanfear
Rates of molecular evolution vary substantially between lineages, and a growing research effort is directed at uncovering the causes and consequences of this variation. Comparing local-clocks (rates of molecular evolution estimated from sets of branches of a phylogenetic tree) is a common tool in this research effort. Here, I show that a commonly used test (the Likelihood Ratio Test, LRT) will not be statistically valid for comparing local-clocks in most cases. Instead, I propose the...

Data from: Predictions of single-nucleotide polymorphism differentiation between two populations in terms of mutual information

Roderick C Dewar, William B Sherwin, Emma Thomas, Clare E Holleley & Richard A Nichols
Mutual information (I) provides a robust measure of genetic differentiation for the purposes of estimating dispersal between populations. At present, however, there is little predictive theory for I. The growing importance in population biology of analyses of single-nucleotide and other single feature polymorphisms (SFPs) is a potent reason for developing an analytic theory for I with respect to a single locus. This study represents a first step towards such a theory. We present theoretical predictions...

Data from: Cross-sectional versus longitudinal research: a case study of trees with hollows and marsupials in Australian forests

David B. Lindenmayer, Jeff Wood, Lachlan McBurney, Damian Michael, Mason Crane, Christopher MacGregor, Rebecca Montague-Drake, Philip Gibbons, Sam C. Banks, D. B. Lindenmayer, J Wood, L McBurney, D Michael, M Crane, C MacGregor, R Montague-Drake, P Gibbons & S. C. Banks
How different are insights based on cross-sectional studies from those of longitudinal investigations? We addressed this question using a detailed case study encompassing a rare suite of inter-connected cross-sectional and longitudinal investigations that have spanned the past two decades and included work on (1) the decay and collapse of large cavity forest trees (termed trees with hollows), (2) populations of a suite of species of arboreal marsupials which are reliant on trees with hollows as...

Data from: Adaptive responses and disruptive effects: how major wildfire influences kinship-based social interactions in a forest marsupial

Sam C Banks, Michaela D J Blyton, David Blair, Lachlan McBurney & David B Lindenmayer
Environmental disturbance is predicted to play a key role in the evolution of animal social behaviour. This is because disturbance affects key factors underlying social systems, such as demography, resource availability and genetic structure. However, because natural disturbances are unpredictable there is little information on their effects on social behaviour in wild populations. Here, we investigated how a major wildfire affected cooperation (sharing of hollow trees) by a hollow-dependent marsupial. We based two alternative social...
