Supplementary data for: Primate phylogenomics uncovers multiple rapid radiations and ancient interspecific introgression

Dan Vanderpool, Bin Quang Minh, Robert Lanfear, Daniel Hughes, Shwetha Murali, R. Alan Harris, Muthuswamy Raveendran, Donna M. Muzny, Richard A. Gibbs, Kim C. Worley, Jeffrey Rogers, Matthew W. Hahn, Mark S. Hibbins & Robert J. Williamson
Our understanding of the evolutionary history of primates is undergoing continual revision due to ongoing genome sequencing efforts. Bolstered by growing fossil evidence, these data have led to increased acceptance of once controversial hypotheses regarding phylogenetic relationships, hybridization and introgression, and the biogeographical history of primate groups. Among these findings is a pattern of recent introgression between species within all major primate groups examined to date, though little is known about introgression deeper in time....

Data from: No link between nymph and adult colouration in shield bugs: weak selection by predators

Iliana Medina, Regina Vega-Trejo, Thomas Wallenius, Damien Esquerre, Constanza Leon, Daniela Perez & Megan Head
Many organisms use different anti-predator strategies throughout their life, but little is known about the reasons or implications of such changes. For years it has been suggested that selection by predators should favour uniformity in local warning signals. If this is the case, we would expect high resemblance in colour across life stages in aposematic animals where young and adults share similar morphology and habitat. In this study we used shield bugs (Hemiptera: Pentatomoidea) to...

Phylogenomics, biogeography and taxonomic revision of New Guinean pythons (Pythonidae, Leiopython) harvested for international trade

Damien Esquerre, Daniel J. D. Natusch, Jessica A. Lyons, Amir Hamidy, Alan R. Lemmon, Emily M. Lemmon, Awal Riyanto, J. Scott Keogh & Stephen Donnellan
The large and enigmatic New Guinean pythons in the genus Leiopython are harvested from the wild to supply the international trade in pets. Six species are currently recognized (albertisii, biakensis, fredparkeri, huonensis, meridionalis, montanus) but the taxonomy of this group has been controversial. We combined analysis of 421 nuclear loci and complete mitochondrial genomes with morphological data to construct a detailed phylogeny of this group, understand their biogeographic patterns and establish the systematic diversity of...

Data for Analysis of Keystone Predation - trait based or driven by extrinsic processes?

Bruce Menge, Melissa Foley, Matthew Robart, Erin Richmond, Mae Noble & Francis Chan
Keystone predation can be a determinant of community structure, including species diversity, but factors underlying “keystoneness” have been minimally explored. Using the system in which the original keystone, the sea star Pisaster ochraceus, was discovered, we focused on two potential (but overlapping) determinants of keystoneness: intrinsic traits or state variables of the species (e.g., size, density), and extrinsic environmental parameters (e.g., prey productivity) that may provide conditions favorable for keystone predator evolution. Using a comparative-experimental...

Linking behavioural thermoregulation, boldness and individual state in male Carpetan rock lizards

Gergely Horváth, Octavio Jiménez-Robles, José Martín, Pilar López, Ignacio De La Riva & Gábor Herczeg
Mechanisms affecting consistent inter-individual behavioural variation (i.e. animal personality) are of wide scientific interest. In poikilotherms, ambient temperature is one of the most important environmental factors with a direct link to a variety of fitness-related traits. Recent empirical evidence suggests that individual differences in boldness are linked to behavioural thermoregulation strategy in heliothermic species, as individuals are regularly exposed to predators during basking. Here, we tested for links between behavioural thermoregulation strategy, boldness and individual...

Data from: Congruence and conflict in the higher-level phylogenetics of squamate reptiles: an expanded phylogenomic perspective

Sonal Singhal, Timothy Colston, Maggie Grundler, Stephen Smith, Gabriel Costa, Guarino Colli, Craig Moritz, Alexander Pyron & Daniel Rabosky
Genome-scale data have the potential to clarify phylogenetic relationships across the tree of life, but have also revealed extensive gene tree conflict. This seeming paradox, whereby larger datasets both increase statistical confidence and uncover significant discordance, suggests that understanding sources of conflict is important for accurate reconstruction of evolutionary history. We explore this paradox in squamate reptiles, the vertebrate clade comprising lizards, snakes, and amphisbaenians. We collected an average of 5103 loci for 91 species...

Lateglacial and Holocene pollen and charcoal records for truwana/Cape Barren Island, Bass Strait, southeast Australia.

Matthew Adeleye, Simon Haberle, Stephen Harris & Felicitas Hopf
We reconstruct long-term vegetation development in a temperate Australian oceanic setting using wetland sediments, pollen and charcoal records from truwana/Cape Barren Island in Bass Strait to reconstruct vegetation and fire history. Magnetic susceptibility and organic content were also derived for two of the four sites considered as proxies for local sedimentary changes. Result shows that the lateglacial landscape (14,000–13000 cal yr BP) was characterized by open grassy Eucalyptus woodland in Bass Strait, and Eucalyptus woodland...

, , , , &
The new deployment of ~25 broadband seismometers will provide the opportunity to dramatically improve the rendering of 3-D seismic structure in the crust and mantle lithosphere. The objective of this work is to provide a compilation of 3-D models, which will be an effective characterisation of the structure of the craton and its margins. These data and models will provide improved information for enhanced assessment of seismic ground shaking from regional earthquakes and facilitate an...

The ‘algebra of evolution’: the Robertson-Price identity and viability selection for body mass in a wild bird population

Gabrielle Hajduk, Craig Walling, Andrew Cockburn & Loeske Kruuk
By the Robertson-Price Identity, the change in a quantitative trait due to selection is equal to the trait’s covariance with relative fitness. We used a long-term study of superb fairy-wrens Malurus cyaneus to consider phenotypic and genetic change within a generation due to juvenile viability selection. Mortality in the four-week period between fledging and independence was 40%, and heavier nestlings were more likely to survive, but why? There was additive genetic variance for both nestling...

Effects of plant functional group removal on CO2 fluxes and belowground C stocks across contrasting ecosystems

Roger Grau-Andrés, David Wardle, Michael Gundale, Claire Foster & Paul Kardol
Changes in plant communities can have large effects on ecosystem carbon (C) dynamics and long-term C stocks. However, how these effects are mediated by environmental context or vary among ecosystems is not well understood. To study this, we used a long-term plant removal experiment set up across 30 forested lake islands in northern Sweden which collectively represent a strong gradient of soil fertility and ecosystem productivity. We measured forest floor CO2 exchange and aboveground and...

Data from: The effects of competition on fitness depend on the sex of both competitors

Megan Head, Samuel Brookes, Maider Iglesias Carrasco & Loeske Kruuk
In intraspecific competition, the sex of competing individuals is likely to be important in determining the consequences of competition, both for the immediate outcome of competitive interactions, and for long-term effects of competition during development on adult fitness traits. Previous studies have explored differences between males and females in their response to intraspecific competition. However, few have tested how the sex of the competitors, or any interactions between focal and competitor sex, influence the nature...

Data from: Oxidative stress delays development and alters gene expression in the agricultural pest moth, Helicoverpa armigera

, Bill James, Karl Gordon, Tom Walsh & Angela McGaughran
Stress is a widespread phenomenon that all organisms must endure. Common in nature is oxidative stress, which can interrupt cell homeostasis to cause cell damage and may be derived from respiration or from environmental exposure through diet. As a result of the routine exposure from respiration, many organisms can mitigate the effects of oxidative stress, but less is known about responses to oxidative stress from other sources. Helicoverpa armigera is a major agricultural pest moth...

Data from: Shifts in reproductive investment in response to competitors lowers male reproductive success

Foteini Spagopoulou, Regina Vega-Trejo, Megan L. Head & Michael D. Jennions
In many species, males exhibit phenotypic plasticity in sexually selected traits when exposed to social cues about the intensity of sexual competition. To date, however, few studies have tested how this plasticity affects male reproductive success. We initially tested whether male mosquitofish, Gambusia holbrooki (Poeciliidae), change their investment in traits under pre- and post- copulatory sexual selection depending on the social environment. Focal males were exposed, for a full spermatogenesis cycle, to visual and chemical...

Data from: Breaking Barriers? Ethnicity and socioeconomic background impact on early career progression in the fields of ecology and evolution

Klara M. Wanelik, Joanne S. Griffin, Megan L. Head, Fiona C. Ingleby & Zenobia Lewis
The academic disciplines of Science, Technology, Engineering and Mathematics (STEM) have long suffered from a lack of diversity. While in recent years there has been some progress in addressing the underrepresentation of women in STEM subjects, other characteristics that have the potential to impact on equality of opportunity have received less attention. In this study, we surveyed 188 early career scientists (ECRs), defined as within ten years of completing their PhD, in the fields of...

Traits data from trees exposed to a 50% reduction in canopy throughfall for 14 years in Caxiuanã, Brazil, September to October 2016

L. Rowland, R.S. Oliveira, P.R.L. Bittencourt, A.L. Giles, I. Coughlin, P. De Britto Costa, T. Domingues, L.V. Ferreira, S.S. Vasconcelos, J.A.S. Junior, A.A.R. Oliveira, A.C.L. Da Costa, P. Meir & M. Mencuccini
Data comprise tree trait data collected during September and October 2016 (the peak dry season), in the Caxiuanã National Forest Reserve, eastern Amazon, Brazil. 17 traits (including plot type, tree species name, diameter at breast height, tree light score, carboxylation capacity, electron transport capacity, leaf respiration in the dark, stomatal conductance, stem CO2 efflux, leaf mass per area, leaf nitrogen and phosphorus content, branch wood density, leaf water potential, xylem pressure, lumen conductance, percentage loss...

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.

Genetic barcoding of museum eggshell improves data integrity of avian biological collections

Alicia Grealy, Naomi Langmore, Leo Joseph & Clare Holleley
Natural history collections are often plagued by missing or inaccurate metadata for collection items, particularly for specimens that are difficult to verify or rare. Avian eggshell in particular can be challenging to identify due to extensive morphological ambiguity among taxa. Species identifications can be improved using DNA extracted from museum eggshell; however, the suitability of current methods for use on small museum eggshell specimens has not been rigorously tested, hindering uptake. In this study, we...

Spatiophylogenetic modelling of extinction risk reveals evolutionary distinctiveness and brief flowering period as threats in a hotspot plant genus

Russell Dinnage, Alexander Skeels & Marcel Cardillo
Comparative models used to predict species threat status can help to identify diagnostic features of species at risk. Such models often combine variables measured at the species level with spatial variables, causing multiple statistical challenges, including phylogenetic and spatial non-independence. We present a novel Bayesian approach for modelling threat status that simultaneously deals with both forms of non-independence and estimates their relative contribution, and we apply the approach to modelling threat status in the Australian...

Survival and home ranges of woodland birds in restoration plantings

Donna Belder, David Lindenmayer, Jennifer Pierson & Ashwin Rudder
Woodland birds are a species assemblage of conservation concern, and their persistence in fragmented agricultural landscapes is dependent on both the preservation of existing woodland remnants and the implementation of restoration plantings. However, little is known about the habitat-use and persistence of birds in fragmented agricultural landscapes. We present a detailed, population-oriented study of woodland birds in temperate eucalypt woodland restoration plantings and remnant woodland patches in the South-west Slopes bioregion of New South Wales,...

Combined effects of rearing and testing temperatures on sperm traits

Megan Head, Maider Iglesias-Carrasco, Lauren Harrison & Michael Jennions
Temperature experienced during early development can affect a range of adult life history traits. Animals often show seemingly adaptive developmental plasticity – with animals reared at certain temperatures performing better as adults at those temperatures. The extent to which this type of adaptive response occurs in gonadal tissue that affect sperm traits is, however, poorly studied. We initially reared male mosquitofish (Gambusia holbrooki) at either 18oC or 30oC, and then measured their sperm reserves as...

Geographic locations of presence points and the size of 14 skull measurements

Rasoul Khosravi, Mahmoud-Reza Hemami, Colin Groves & Mohsen Ahmadi
The phylogeny and species boundaries of Gazella subgutturosa and G. marica have been long debated. The achievements of past conservation efforts have been compromised by a lack of knowledge about the phylogeny and taxonomic status of different populations. We integrated the recent genetic findings by previous studies with morphometric analyses and ecological niche modelling (ENM) to assess discreteness among populations of these gazelle species in Asia. Taxonomic diversity of gazelles was investigated by using principal...

Genetic data improves niche model discrimination and alters the direction and magnitude of climate change forecasts

Helen Bothwell, Luke Evans, Erika Hersch-Green, Scott Woolbright, Gerard Allan & Thomas Whitham
Ecological niche models (ENMs) have classically operated under the simplifying assumptions that there are no barriers to gene flow, species are genetically homogeneous (i.e., no population-specific local adaptation), and all individuals share the same niche. Yet, these assumptions are violated for most broadly distributed species. Here we incorporate genetic data from the widespread riparian tree species narrowleaf cottonwood (Populus angustifolia) to examine whether including intraspecific genetic variation can alter model performance and predictions of climate...

Stress in the city: meta-analysis indicates no overall evidence for stress in urban vertebrates

Maider Iglesias-Carrasco
As cities continue to grow it is increasingly important to understand the long-term responses of wildlife to urban environments. There have been increased efforts to determine whether urbanization imposes chronic stress on wild animals, but empirical evidence is mixed. Here we conduct a meta-analysis to test whether there is, on average, a detrimental effect of urbanisation based on baseline and stress-induced glucocorticoid levels of wild vertebrates. We found no effect of urbanisation on glucocorticoid levels,...

Experimental vacancies do not induce settlement despite habitat saturation in a cooperative breeder

Lyanne Brouwer & Andrew Cockburn
The paradox of cooperative breeding ­whereby individuals assist others instead of reproducing independently­ is generally explained through ecological constraints, but experimental evidence is scant. Here we performed the crucial test of the role of habitat saturation through experimental creation of vacancies and find that despite abundant presence of potential mates, subordinates are reluctant to disperse into suitable vacant habitat where conspecifics are absent. We argue that sudden disappearance of multiple group members might indicate a...

What factors influence the extent of midstorey development in Mountain Ash forests?

David Lindenmayer, Wade Blanchard, Lachlan McBurney, Kita Ashman, Elle Bowd & Blair David
The midstorey is a critical component of the structure of many kinds of forest globally. We constructed statistical models of the factors influencing the percentage cover of two dominant Acacia spp. (Montane Wattle [Acacia frigiscens]) and Silver Wattle [Acacia dealbata]) in the midstorey of Mountain Ash (Eucalyptus regnans) forests in mainland south-eastern Australia. We modelled the influence on the percentage cover of two these two species of Acacia of : (1) the age of the...
