Data from: Sex differences in parental care: gametic investment, sexual selection and social environment

András Liker, Robert P. Freckleton, Vladimir Remes & Tamás Székely
Male and female parents often provide different type and amount of care to their offspring. Three major drivers have been proposed to explain parental sex roles: (i) differential gametic investment by males and females that precipitates into sex difference in care, (ii) different intensity of sexual selection acting on males and females, and (iii) biased social environment that facilitates the more common sex to provide more care. Here we provide the most comprehensive assessment of...

Data from: Lineage-specific sequence evolution and exon edge conservation partially explain the relationship of evolutionary rate and expression level in A. thaliana

Stephen J. Bush, Paula X. Kover & Araxi O. Urrutia
Rapidly evolving proteins can aid the identification of genes underlying phenotypic adaptation across taxa, but functional and structural elements of genes can also affect evolutionary rates. In plants, the ‘edges’ of exons, flanking intron junctions, are known to contain splice enhancers and to have a higher degree of conservation compared to the remainder of the coding region. However, the extent to which these regions may be masking indicators of positive selection or account for the...

Data from: Contrasting genetic diversity and population structure among three sympatric Madagascan shorebirds: parallels with rarity, endemism, and dispersal

Luke Eberhart-Phillips, Joseph I. Hoffman, Edward G. Brede, Sama Zefania, Martina J. Kamrad, Tamas Szekely, Michael W. Bruford & Luke J. Eberhart-Phillips
Understanding the relative contributions of intrinsic and extrinsic factors to population structure and genetic diversity is a central goal of conservation and evolutionary genetics. One way to achieve this is through comparative population genetic analysis of sympatric sister taxa, which allows evaluation of intrinsic factors such as population demography and life history while controlling for phylogenetic relatedness and geography. We used ten conserved microsatellites to explore the population structure and genetic diversity of three sympatric...

Data from: The constrained maximal expression level owing to haploidy shapes gene content on the mammalian X chromosome

Laurence D. Hurst, Avazeh T. Ghanbarian, Alistair R. R. Forrest, Fantom Consortium & Lukasz Huminiecki
X chromosomes are unusual in many regards, not least of which is their nonrandom gene content. The causes of this bias are commonly discussed in the context of sexual antagonism and the avoidance of activity in the male germline. Here, we examine the notion that, at least in some taxa, functionally biased gene content may more profoundly be shaped by limits imposed on gene expression owing to haploid expression of the X chromosome. Notably, if...

Data from: Optimisation of next generation sequencing transcriptome annotation for species lacking sequenced genomes

Nina F. Ockendon, Lauren A. O'Connell, Stephen J. Bush, Jimena Monzon-Sandoval, Holly Barnes, Tamás Székely, Hans A. Hofmann, Steve Dorus & Araxi O. Urrutia
Next generation sequencing methods, such as RNA-seq, have permitted the exploration of gene expression in a range of organisms which have been studied in ecological contexts but lack a sequenced genome. However, the efficacy and accuracy of RNA-seq annotation methods using reference genomes from related species have yet to be robustly characterised. Here we conduct a comprehensive power analysis employing RNA-seq data from Drosophila melanogaster in conjunction with 11 additional genomes from related Drosophila species...

Data from: Comparable disparity in the appendicular skeleton across the fish-tetrapod transition, and the morphological gap between fish and tetrapod postcrania

Marcello Ruta & Matthew A. Wills
Appendicular skeletal traits are used to quantify changes in morphological disparity and morphospace occupation across the fish–tetrapod transition and to explore the informativeness of different data partitions in phylogeny reconstruction. Anterior appendicular data yield trees that differ little from those built from the full character set, whilst posterior appendicular data result in considerable loss of phylogenetic resolution and tree branch rearrangements. Overall, there is a significant incongruence in the signals associated with pectoral and pelvic...

Data from: Visual and non-visual navigation in blind patients with a retinal prosthesis

Sara Garcia, Karin Petrini, Gary S. Rubin, Lyndon Da Cruz & Marko Nardini
Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new visual signal together with non-visual information when navigating. Four patients (blind for 15-52 years) implanted with the Argus II retinal prosthesis (Second Sight Medical Products Inc. Sylmar, CA), and five age-matched and six younger controls, participated. Participants completed...

Data from: Cold-seeking behaviour mitigates reproductive losses from fungal infection in Drosophila

Vicky L. Hunt, Weihao Zhong, Colin D. McClure, David T. Mlynski, Elizabeth M. L. Duxbury, A. Keith Charnley, Nicholas K. Priest & Elizabeth M.L. Duxbury
1. Animals must tailor their life history strategies to suit the prevailing conditions and respond to hazards in the environment. Animals with lethal infections are faced with a difficult choice: to allocate more resources to reproduction and suffer higher mortality or to reduce reproduction with the expectation of enhanced immunity and late-age reproduction. But, how they do this is largely unknown. 2. Here, we have investigated the temperature preference of the fruit fly, Drosophila melanogaster,...

Data from: Calibrating animal-borne proximity loggers

Christian Rutz, Michael B. Morrissey, Zackory T. Burns, John Burt, Brian Otis, James J. H. St Clair & Richard James
1. Growing interest in the structure and dynamics of animal social networks has stimulated efforts to develop automated tracking technologies that can reliably record encounters in free-ranging subjects. A particularly promising approach is the use of animal-attached ‘proximity loggers’, which collect data on the incidence, duration and proximity of spatial associations through inter-logger radio communication. While proximity logging is based on a straightforward physical principle – the attenuation of propagating radio waves with distance –...

Data from: The evolution of parental cooperation in birds

Vladimír Remeš, Robert P. Freckleton, Jácint Tökölyi, András Liker & Tamás Székely
Parents in many animal species care for their offspring. In some species, males care more; in other species, females care more; in still other species, the contribution of the sexes is equal. However, we do not know what explains these differences among species. Using the most comprehensive analyses of parental care to date, here we show that parents cooperate more when sexual selection is not intense and the adult sex ratio of males to females...
