Data from: Weak evidence for anticipatory parental effects in plants and animals

Tobias Uller, Shinichi Nakagawa & Sinead English
The evolution of adaptive phenotypic plasticity relies on the presence of cues that enable organisms to adjust their phenotype to match local conditions. Although mostly studied with respect to nonsocial cues, it is also possible that parents transmit information about the environment to their offspring. Such ‘anticipatory parental effects’ or ‘adaptive transgenerational plasticity’ can have important consequences for the dynamics and adaptive potential of populations in heterogeneous environments. Yet, it remains unknown how widespread this...

Data from: Rates of dinosaur limb evolution provide evidence for exceptional radiation in Mesozoic birds

Roger B. J. Benson & Jonah N. Choiniere
Birds are the most diverse living tetrapod group and are a model of large-scale adaptive radiation. Neontological studies suggest a radiation within the avian crown group, long after the origin of flight. However, deep time patterns of bird evolution remain obscure because only limited fossil data have been considered. We analyse cladogenesis and limb evolution on the entire tree of Mesozoic theropods, documenting the dinosaur–bird transition and immediate origins of powered flight. Mesozoic birds inherited...

Data from: Measurement, variation, and scaling of osteocyte lacunae: a case study in birds

Michael D. D'Emic, Roger B. J. Benson & Roger B.J. Benson
Basic issues surrounding osteocyte biology are still poorly understood, including the variability of osteocyte morphology within and among bones, individuals, and species. Several studies have suggested that the volume or shape of osteocytes (or their lacunae) are related to bone and/or organismal growth rate or metabolism, but the nature of this relationship, if any, is unclear. Furthermore, several studies have linked osteocyte lacuna volume with genome size or growth rate and suggested that osteocyte lacuna...

Data from: A trade-off between oxidative stress resistance and DNA repair plays a role in the evolution of elevated mutation rates in bacteria

Clara Torres-Barceló, Gabriel Cabot, Antonio Oliver, Angus Buckling, R. Craig MacLean & C. Torres-Barcelo
The dominant paradigm for the evolution of mutator alleles in bacterial populations is that they spread by indirect selection for linked beneficial mutations when bacteria are poorly adapted. In this paper, we challenge the ubiquity of this paradigm by demonstrating that a clinically important stressor, hydrogen peroxide, generates direct selection for an elevated mutation rate in the pathogenic bacterium Pseudomonas aeruginosa as a consequence of a trade-off between the fidelity of DNA repair and hydrogen...

Data from: Fine-scale genetic structure in a wild bird population: the role of limited dispersal and environmentally-based selection as causal factors

Colin Garroway, Reinder J. Radersma, Irem Sepil, Anna W. Santure, Isabelle De Cauwer, Jon Slate, Ben C. Sheldon, Colin J. Garroway & Reinder Radersma
Individuals are typically not randomly distributed in space; consequently ecological and evolutionary theory depends heavily on understanding the spatial structure of populations. The central challenge of landscape genetics is therefore to link spatial heterogeneity of environments to population genetic structure. Here, we employ multivariate spatial analyses to identify environmentally induced genetic structures in a single breeding population of 1174 great tits Parus major genotyped at 4701 single-nucleotide polymorphism (SNP) loci. Despite the small spatial scale...

Mimetic host shifts in a social parasite of ants: Caterpillar survivors in Myrmica nests

K. Schönrogge, J. A. Thomas, G.W. Elmes, M. Sielezniew, A. Stankiewicz-Fiedurek, D. Simcox & J. Settele
This dataset is part of the study of mimetic host shifts in an endangered social parasite of ants, which is a joint study of the NERC's Centre for Ecology & Hydrology(UK), the University of Oxford(UK), University of Bialystok(Poland), Polish Academy of Sciences(Poland) and UFZ Helmholtz Centre for Environmental Research(Germany). Combined with datasets collected from previous study, they compare the proportions of caterpillars of Maculinea rebeli being adopted by resident Myrmica ant species near Przemysl, Poland...

Data from: Can natural selection favour altruism between species?

Gregory A. K. Wyatt, Stuart A. West & Andy Gardner
Darwin suggested that the discovery of altruism between species would annihilate his theory of natural selection. However, it has not been formally shown whether between-species altruism can evolve by natural selection, or why this could never happen. Here, we develop a spatial population genetic model of two interacting species, showing that indiscriminate between species helping can be favoured by natural selection. We then ask if this helping behaviour constitutes altruism between species, using a linear-regression...

Data from: Remnant Pachira quinata pasture trees have greater opportunities to self and suffer reduced reproductive success due to inbreeding depression

Paul D. Rymer, Mark Sandiford, Stephen A. Harris, Martin R. Billingham & David H. Boshier
Habitat fragmentation is extensive throughout the world, converting natural ecosystems into fragments of varying size, density and connectivity. The potential value of remnant trees in agricultural landscapes as seed sources and in connecting fragments has formed a fertile area of debate. This study contrasted the mating patterns of bat-pollinated Pachira quinata trees in a continuous forest to those in pasture through microsatellite-based paternity analysis of progeny. The breeding system was determined by analysis of pollen...

Data from: Boom and bust: ancient and recent diversification in bichirs (Polypteridae: Actinopterygii), a relictual lineage of ray-finned fishes

Thomas J. Near, Alex Dornburg, Masayoshi Tokita, Dai Suzuki, Matthew C. Brandley & Matt Friedman
Understanding the history that underlies patterns of species richness across the Tree of Life requires an investigation of the mechanisms that not only generate young species-rich clades, but also those that maintain species-poor lineages over long stretches of evolutionary time. However, diversification dynamics that underlie ancient species-poor lineages are often hidden due to a lack of fossil evidence. Using information from the fossil record and time calibrated molecular phylogenies, we investigate the history of lineage...

Data from: Replicated high-density genetic maps of two great tit populations reveal fine-scale genomic departures from sex-equal recombination rates

Kees Van Oers, Anna W. Santure, Isabelle De Cauwer, Nikkie E. M. Van Bers, Richard P. M. A. Crooijmans, Ben C. Sheldon, Marcel E. Visser, Jon Slate & Martien A. M. Groenen
Linking variation in quantitative traits to variation in the genome is an important, but challenging task in the study of life-history evolution. Linkage maps provide a valuable tool for the unravelling of such trait-gene associations. Moreover, they give insight into recombination landscapes and between- species karyotype evolution. Here we used genotype data, generated from a 10k SNP-chip, of over 2000 individuals to produce high-density linkage maps of the great tit (Parus major), a passerine bird,...

Data from: Advancing population ecology with integral projection models: a practical guide

Cory Merow, Johan P. Dalgren, C. Jessica E. Metcalf, Dylan Z. Childs, M. E. K. Evans, Eelke Jongejans, Sydne Record, Mark Rees, Roberto Salguero-Gómez, Sean M. McMahon, Margaret E.K. Evans & Johan P. Dahlgren
Integral Projection Models (IPMs) use information on how an individual's state influences its vital rates - survival, growth and reproduction - to make population projections. IPMs are constructed from regression models predicting vital rates from state variables (e.g., size or age) and covariates (e.g., environment). By combining regressions of vital rates, an IPM provides mechanistic insight into emergent ecological patterns such as population dynamics, species geographic distributions, or life history strategies. Here, we review important...

Data from: Protection against a fungal pathogen conferred by the aphid facultative endosymbionts Rickettsia and Spiroplasma is expressed in multiple host genotypes and species and is not influenced by co-infection with another symbiont

Piotr Łukasik, Huifang Guo, Margriet Van Asch, Julia Ferrari & H. Charles J. Godfray
Many insects harbour facultative endosymbiotic bacteria, often more than one type at a time. These symbionts can have major effects on their hosts' biology, which may be modulated by the presence of other symbiont species and by the host's genetic background. We investigated these effects by transferring two sets of facultative endosymbionts (one Hamiltonella and Rickettsia, the other Hamiltonella and Spiroplasma) from naturally double-infected pea aphid hosts into five novel host genotypes of two aphid...

Data from: Haplotype structure, adaptive history and associations with exploratory behaviour of the DRD4 gene region in four great tit (Parus major) populations

Jakob C. Mueller, Peter Korsten, Christine Hermannstädter, Thomas Feulner, Niels J. Dingemanse, Erik Matthysen, Kees Van Oers, Thijs Van Overveld, Samantha C. Patrick, John L. Quinn, Matthias Riemenschneider, Joost M. Tinbergen, Bart Kempenaers & Christine Hermannstaedter
The assessment of genetic architecture and selection history in genes for behavioural traits is fundamental to our understanding of how these traits evolve. The dopamine receptor D4 (DRD4) gene is a prime candidate for explaining genetic variation in novelty seeking behaviour, a commonly assayed personality trait in animals. Previously we showed that a single nucleotide polymorphism in exon 3 of this gene is associated with exploratory behaviour in at least one of four Western European...

Data from: Genomic dissection of variation in clutch size and egg mass in a wild great tit (Parus major) population

Anna W. Santure, Isabelle De Cauwer, Jocelyn Poissant, Matthew R. Robinson, Jon Slate & Ben C. Sheldon
Clutch size and egg mass are life history traits that have been extensively studied in wild bird populations, as life history theory predicts a negative trade-off between them, either at the phenotypic or genetic level. Here, we analyse the genomic architecture of these heritable traits in a wild great tit (Parus major) population, using three marker-based approaches - chromosome partitioning, quantitative trait locus (QTL) mapping and a genome-wide association study (GWAS). The variance explained by...

Data from: A new exceptionally preserved Cambrian priapulid from the Chengjiang Lagerstätte

Xiaoya Ma, Richard J. Aldridge, David J. Siveter, Derek J. Siveter, Xianguang Hou & Gregory D. Edgecombe
A fossil priapulid, Eximipriapulus globocaudatus new genus new species, is described from the Cambrian Chengjiang Lagerstätte of Yunnan, China. The exceptional preservation of the animal reveals morphological details that allow direct comparison with extant priapulids. The body is divisible into a partially eversible pharynx, a smooth collar, a scalid-bearing introvert, a neck with triangular scalids, an unsegmented trunk with annulations, and a distinctly expanded terminal region. Several specialized regions of the alimentary canal are recognized:...

Data from: The evolution of bacterial mutation rates under simultaneous selection by inter-specific and social parasitism

Siobhán O'Brien, Antonio M. M. Rodrigues & A. Buckling
Many bacterial populations harbour substantial numbers of hypermutable bacteria, in spite of hypermutation being associated with deleterious mutations. One reason for the persistence of hypermutators is the provision of novel mutations, enabling rapid adaptation to continually changing environments, for example coevolving virulent parasites. However, hypermutation also increases the rate at which intraspecific parasites (social cheats) are generated. Interspecific and intraspecific parasitism are therefore likely to impose conflicting selection pressure on mutation rate. Here, we combine...

Data from: Cryptic female choice favours sperm from MHC-dissimilar males

Hanne Løvlie, Mark A. F. Gillingham, Kirsty Worley, Tommaso Pizzari, David S. Richardson & H. Lovlie
Cryptic female choice may enable polyandrous females to avoid inbreeding or bias offspring variability at key loci after mating. However, the role of these genetic benefits in cryptic female choice remains poorly understood. Female red junglefowl, Gallus gallus, bias sperm use in favour of unrelated males. Here, we experimentally investigate whether this bias is driven by relatedness per se, or by similarity at the major histocompatibility complex (MHC), genes central to vertebrate acquired immunity, where...

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,...

Data from: Evolutionary reversals of antibiotic resistance in experimental populations of Pseudomonas aeruginosa

Danna R. Gifford & R. Craig MacLean
Antibiotic resistance mutations are accompanied by a fitness cost, and two mechanisms allow bacteria to adapt to this cost once antibiotic use is halted. First, it is possible for resistance to revert; second, it is possible for bacteria to adapt to the cost of resistance by compensatory mutations. Unfortunately, reversion to antibiotic sensitivity is rare, but the underlying factors that prevent reversion remain obscure. Here, we directly study the evolutionary dynamics of reversion by experimentally...

Data from: Genome-wide association study identifies vitamin B5 biosynthesis as a host specificity factor in Campylobacter

Samuel K. Sheppard, Xavier Didelot, Guillaume Meric, Alicia Torralbo, Keith A. Jolley, David J. Kelly, Stephen D. Bentley, Martin C. J. Maiden, Julian Parkhill & Daniel Falush
Genome-wide association studies have the potential to identify causal genetic factors underlying important phenotypes but have rarely been performed in bacteria. We present an association mapping method that takes into account the clonal population structure of bacteria and is applicable to both core and accessory genome variation. Campylobacter is a common cause of human gastroenteritis as a consequence of its proliferation in multiple farm animal species and its transmission via contaminated meat and poultry. We...

Data from: Sex-specific responses to sexual familiarity, and the role of olfaction in Drosophila

Cedric K. W. Tan, Hanne Løvlie, Elisabeth Greenway, Stephen F. Goodwin, Tommaso Pizzari, Stuart Wigby & H. Lovlie
Studies of mating preferences have largely neglected the potential effects of individuals encountering their previous mates (‘directly sexually familiar’), or new mates that share similarities to previous mates, e.g. from the same family and/or environment (‘phenotypically sexually familiar’). Here, we show that male and female Drosophila melanogaster respond to the direct and phenotypic sexual familiarity of potential mates in fundamentally different ways. We exposed a single focal male or female to two potential partners. In...

Mimetic host shifts in a social parasite of ants: Analytical data of surface semio-chemicals on Maculinea rebeli larvae

The data comprise datasets collected from four 4 experiments 3 hours after testing and from 4 experiments 7 days later. They all include nest numbers, the order of retrieval ranked by the attention of nurse ants to the ant pupae, large larvae and small larvae and the adult Maculinea rebeli. The data give the...

Data from: A giant pliosaurid skull from the Late Jurassic of England

Roger B. J. Benson, Mark Evans, Adam S. Smith, Judyth Sassoon, Scott Moore-Faye, Hilary F. Ketchum & Richard Forrest
Pliosaurids were a long-lived and cosmopolitan group of marine predators that spanned 110 million years and occupied the upper tiers of marine ecosystems from the Middle Jurassic until the early Late Cretaceous. A well-preserved giant pliosaurid skull from the Late Jurassic Kimmeridge Clay Formation of Dorset, United Kingdom, represents a new species, Pliosaurus kevani. This specimen is described in detail, and the taxonomy and systematics of Late Jurassic pliosaurids is revised. We name two additional...
