Data from: Retracted: Experimental evidence that maternal corticosterone controls adaptive offspring sex ratios

Sarah R. Pryke, Lee A. Rollins, Simon C. Griffith, Buttemer A. William & William A. Buttemer
THIS ARTICLE HAS BEEN RETRACTED 1. Sex allocation theory has received considerable attention, yet the mechanism(s) by which mothers skew offspring sex ratios remain unknown. In birds, females are the heterogametic sex, which potentially gives them control of whether gametes will be male or female. How females might control the sex of the gamete is unclear, but one possibility is that variation in steroid hormones may mediate this process. 2. We experimentally altered circulating levels...

Data from: Juvenile social experience affects pairing success at adulthood: congruence with the loser effect?

Mylene M. Mariette, Charlène Cathaud, Rémi Chambon & Clémentine Vignal
Social interactions with adults are often critical for the development of mating behaviours. However, the potential role of other primary social partners such as juvenile counterparts is rarely considered. Most interestingly, it is not known whether interactions with juvenile females improve males’ courtship and whether, similar to the winner and loser effects in a fighting context—outcome of these interactions shapes males’ behaviour in future encounters. We investigated the combined effects of male quality and juvenile...

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: Juveniles and migrants as drivers for seasonal epizootics of avian influenza virus

Jacintha G. B. Van Dijk, Bethany J. Hoye, Josanne H. Verhagen, Bart A. Nolet, Ron A. M. Fouchier & Marcel Klaassen
1. Similar to other infectious diseases, the prevalence of low pathogenic avian influenza viruses (LPAIV) has been seen to exhibit marked seasonal variation. However, mechanisms driving this variation in wild birds have yet to be tested. We investigated the validity of three previously suggested drivers for the seasonal dynamics in LPAIV infections in wild birds: (1) host density, (2) immunologically-naïve young, and (3) increased susceptibility in migrants. 2. To address these questions, we sampled a...

Data from: Environmental and genetic control of brain and song structure in the zebra finch

Joseph Luke Woodgate, Katherine L. Buchanan, Andrew T. D. Bennett, Clive K. Catchpole, Roswitha Brighton, Stefan Leitner & Andrew T.D. Bennett
Birdsong is a classic example of a learned trait with cultural inheritance, with selection acting on trait expression. To understand how song responds to selection, it is vital to determine the extent to which variation in song learning and neuroanatomy is attributable to genetic variation, environmental conditions, or their interactions. Using a partial cross fostering design with an experimental stressor, we quantified the heritability of song structure and key brain nuclei in the song control...
