Data from: Evidence that hepatitis C virus genome partly controls infection outcome

Matthew Hartfield, Rowena Bull, Peter A. White, Andrew Lloyd, Fabio Luciani & Samuel Alizon
Infection by hepatitis C virus (HCV) leads to one of two outcomes; either the infection resolves within approximately 6 months or the virus can persist indefinitely. Host genetics are known to affect the likelihood of clearance or persistence. By contrast, the importance of the virus genotype in determining infection outcome is unknown, as quantifying this effect traditionally requires well-characterized transmission networks, which are rare. Extending phylogenetic approaches previously developed to estimate the virus control over...

Data from: Correlational selection does not explain the evolution of a behavioural syndrome

Chang S. Han & Robert C. Brooks
Correlated suites of behaviours, or behavioural syndromes, appear to be widespread, and yet few studies have explored how they arise and are maintained. One possibility holds that correlational selection can generate and maintain behavioural syndrome if certain behavioural combinations enjoy greater fitness than other combinations. Here we test this correlational selection hypothesis by comparing behavioural syndrome structure with a multivariate fitness surface based on reproductive success of male water striders. We measured the structure of...

Data from: The active metabolic rate predicts a male spider’s proximity to females and expected fitness

Michael M. Kasumovic & F. Seebacher
Conspicuous traits, such as weaponry and body size, are often correlated with fitness. By contrast, we understand less about how inconspicuous physiological traits affect fitness. Not only is linking physiology directly to fitness a challenge, but in addition, behavioural studies most often focus on resting or basal metabolic rates, resulting in a poor understanding of how active metabolic rates affect fitness. Here we use the golden orb-web spider (Nephila plumipes), a species for which proximity...

Data from: The biomechanical basis of evolutionary change in a territorial display

Terry J. Ord, David C. Collar & Thomas J. Sanger
1. Few studies have examined how the anatomy of an animal signal contributes to, or limits, the evolution of signal differentiation among closely related species. 2. In Anolis lizards, adult males extend a large, conspicuous dewlap as part of a territorial advertisement display. Males of species from the island of Jamaica rely on the rapid extension of the dewlap to facilitate display detection by territorial neighbours and conspecific females. Males of other species on the...

Data from: Sex-specific evolutionary potential of pre- and postcopulatory reproductive interactions in the field cricket, Teleogryllus commodus

Matthew D. Hall, Simon P. Lailvaux & Robert C. Brooks
Mate choice often depends on the properties of both sexes, such as the preference and responsiveness of the female and the sexual display traits of the male. Quantitative genetic studies, however, traditionally explore the outcome of an interaction between males and females based solely on the genotype of one sex, treating the other sex as a source of environmental variance. Here we use a half-sib breeding design in the field cricket, Teleogryllus commodus, to estimate...

Data from: Do changes in grazing pressure and the degree of shrub encroachment alter the effects of individual shrubs on understorey plant communities and soil function?

Santiago Soliveres & David J. Eldridge
1. Shrub encroachment has dramatically altered the structure and functioning of many dryland ecosystems worldwide. While positive effects of shrubs on their understorey are commonly found (patch-level effects), these effects can be either positive or negative when scaled up to the community or landscape level (landscape-level effects). These contrasting results are likely to be caused by differences in the degree of shrub encroachment or grazing pressure among studies. No study has addressed the relationship between...

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: A biogeographical regionalisation of Australian Acacia species

Carlos E. González-Orozco, Shawn W. Laffan, Nunzio Knerr & Joseph T. Miller
Aim: To develop a biogeographical regionalization of Australian Acacia species and to investigate their environmental correlates. Location: Australia. Methods: We used a previously published framework for delineating biogeographical regions. We calculated species turnover patterns of 1020 Australian Acacia species with distributions estimated from 171,758 georeferenced herbarium records aggregated to 100 km × 100 km cells (868 across Australia). An agglomerative cluster analysis using a matrix of pairwise Simpson's beta (βsim) dissimilarity values was applied. Eleven...

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: Homing pigeons respond to time-compensated solar cues even in sight of the loft

Chris Armstrong, Helen Wilkinson, Jessica Meade, Dora Biro, Robin Freeman & Tim Guilford
The sun has long been thought to guide bird navigation as the second step in a two-stage process, in which determining position using a map is followed by course setting using a compass, both over unfamiliar and familiar terrain. The animal’s endogenous clock time-compensates the solar compass for the sun’s apparent movement throughout the day, and this allows predictable deflections in orientation to test for the compass’ influence using clock-shift manipulations. To examine the influence...

Data from: Natural selection in novel environments: predation selects for background matching in the body colour of a land fish

Courtney L. Morgans & Terry J. Ord
The invasion of a novel habitat often results in a variety of new selective pressures on an individual. One pressure that can severely impact population establishment is predation. The strategies that animals use to minimize predation, especially the extent to which those strategies are habitat or predator specific, will subsequently affect an individuals’ dispersal ability. The invasion of land by a fish, the Pacific leaping blenny, Alticus arnoldorum, offers a unique opportunity to study natural...

Data from: Causes of male sexual trait divergence in introduced populations of guppies

Anna K. Lindholm, Megan L. Head, Robert C. Brooks, Lee A. Rollins, Fiona C. Ingleby & Susanne R. K. Zajitschek
Males from different populations of the same species often differ in their sexually selected traits. Variation in sexually selected traits can be attributed to sexual selection if phenotypic divergence matches the direction of sexual selection gradients among populations. However, phenotypic divergence of sexually selected traits may also be influenced by other factors, such as natural selection and genetic constraints. Here, we document differences in male sexual traits among six introduced Australian populations of guppies and...

Data from: Convergent evolution in the territorial communication of a classic adaptive radiation: Caribbean Anolis lizards

Terry J. Ord, Judy A. Stamps & Jonathan B. Losos
To demonstrate adaptive convergent evolution, it must be shown that shared phenotypes have evolved independently in different lineages and that a credible selection pressure underlies adaptive evolution. There are a number of robust examples of adaptive convergence in morphology for which both these criteria have been met, but examples from animal behaviour have rarely been tested as rigorously. Adaptive convergence should be common in behaviour, especially behaviour used for communication, because the environment often shapes...

Data from: The osteology and systematics of the enigmatic Australian Oligo-Miocene metatherian Yalkaparidon (Yalkaparidontidae; Yalkaparidontia; Australidelphia; Marsupialia)

Robin M. D. Beck, Kenny J. Travouillon, Ken P. Aplin, Henk Godthelp & Michael Archer
We provide the first detailed description of the osteology of the enigmatic Oligo-Miocene Australian metatherian Yalkaparidon. This taxon exhibits a number of unusual craniodental apomorphies but appears to be plesiomorphic within Metatheria in retaining four molars, rather than three as previously reported. We demonstrate that the only known skull of Yalkaparidon almost certainly represents a single individual. We also tentatively refer a number of isolated tarsals to the genus. Maximum parsimony analyses of a 258...

Data from: Sex-dependent evolution of life-history traits following adaptation to climate warming

Björn Rogell, William Widegren, Lára R. Hallsson, David Berger, Mats Björklund & Alexei A. Maklakov
1. Thermodynamic processes increase metabolic rate and decrease longevity at high temperatures in ectotherms. However, how sustained long-term increase in temperature affects the evolution of longevity is poorly understood. 2. Stress theory of ageing predicts that increased longevity is positively genetically correlated with resistance to different types of environmental stressors implying that evolutionary trajectories of ageing may be mediated by correlative selection for robust phenotypes under thermal stress. 3. Here, we test this hypothesis by...

Data from: Limited plasticity in the phenotypic variance-covariance matrix for male advertisement calls in the black field cricket, Teleogryllus commodus

William R. Pitchers, Robert Brooks, Michael D. Jennions, Tom Tregenza, Ian Dworkin & John Hunt
Phenotypic integration and plasticity are central to our understanding of how complex phenotypic traits evolve. Evolutionary change in complex quantitative traits can be predicted using the multivariate breeders’ equation, but such predictions are only accurate if the matrices involved are stable over evolutionary time. Recent study, however, suggests that these matrices are temporally plastic, spatially variable and themselves evolvable. The data available on phenotypic variance-covariance matrix (P) stability are sparse, and largely focused on morphological...

Data from: Sex-specific patterns of morphological diversification: evolution of reaction norms and static allometries in neriid flies

Elizabeth J. Cassidy, Eleanor Bath, Stephen F. Chenoweth & Russell Bonduriansky
The consequences of sex-specific selection for patterns of diversification remain poorly known. Because male secondary sexual traits are typically costly to express, and both costs and benefits are likely to depend on ambient environment and individual condition, such traits may be expected to diversify via changes in reaction norms as well as the scaling of trait size with body size (static allometry). We investigated morphological diversification within two species of Australian neriid flies (Telostylinus angusticollis,...
