Data from: Reticulate evolution within a spruce (Picea) species complex revealed by population genomic analysis

Yongshuai Sun, Richard J. Abbott, Zhiqiang Lu, Kangshan Mao, Lei Zhang, Xiaojuan Wang, Dafu Ru & Jianquan Liu
The role of reticulation in the rapid diversification of organisms is attracting greater attention in evolutionary biology. Here, we report a population genomics approach to test the role of hybridization and introgression in the evolution of the Picea likiangensis species complex. Based on 84,793 SNPs detected in transcriptomes of 82 trees collected from 35 localities, we identified 18 hybrids (including backcrosses) distributed within the range boundaries of the four taxa. Coalescent simulations, for each pair...

Data from: Patterns of phenotypic plasticity and local adaptation in the wide elevation range of the alpine plant Arabis alpina

Pierre De Villemereuil, Médéric Mouterde, Oscar E. Gaggiotti & Irène Till-Bottraud
Local adaptation and phenotypic plasticity are two important characteristics of alpine plants to overcome the threats caused by global changes. Among alpine species, Arabis alpina is characterised by an unusually wide altitudinal amplitude, ranging from 800 to 3,100 m of elevation in the French Alps. Two non‐exclusive hypotheses can explain the presence of A. alpina across this broad ecological gradient: adaptive phenotypic plasticity or local adaptation, making this species especially useful to better understand these...

Data from: A 2.6‐g sound and movement tag for studying the acoustic scene and kinematics of echolocating bats

Laura Stidsholt, Mark Johnson, Kristian Beedholm, Lasse Jakobsen, Kathrin Kugler, Signe Brinkløv, Angeles Salles, Cynthia F. Moss & Peter Teglberg Madsen
1. To study sensorimotor behaviour in wild animals, it is necessary to synchronously record the sensory inputs available to the animal, and its movements. To do this, we have developed a biologging device that can record the primary sensory information and the associated movements during foraging and navigating in echolocating bats. 2. This 2.6 -gram tag records the sonar calls and echoes from an ultrasonic microphone, while simultaneously sampling fine-scale movement in three dimensions from...

Data from: Demographic expansion and genetic load of the halophyte model plant Eutrema salsugineum

Xiao-Juan Wang, Quan-Jun Hu, Xin-Yi Guo, Kun Wang, Da-Fu Ru, Dmitry A. German, Elizabeth A. Weretilnyk, Richard J. Abbott, Martin Lascoux & Jian-Quan Liu
Eutrema salsugineum is a widely distributed species, which provide a good model to study long-distance dispersal and accumulation of deleterious mutations. Based on population genomic data, we clarified demographic history of E. salsugineum and showed how deleterious alleles accumulated.

Data from: The fitness effects of a pale mutant in the aposematic seed bug Lygaeus simulans indicate pleiotropy between warning coloration and life history

Vicki L. Balfour, Cédric Aumont, Liam R. Dougherty & David M. Shuker
Conspicuous warning colours that signal chemical or other defences are common in the natural world. For instance, such aposematic warning patterns of red-and-black or yellow-and-black are common among insect taxa, particularly in the order Hemiptera, often forming the basis of Batesian and/or Müllerian mimicry rings. In addition, it has been repeatedly noted that colour polymorphisms or mutants that influence pigmentation can show pleiotropy with other behavioural, physiological or life-history traits. Here we describe a pale...

Data from: Seasonal differences in baseline innate immune function are better explained by environment than annual cycle stage in a year-round breeding tropical songbird

Chima J. Nwaogu, Will Cresswell, Maaike A. Versteegh & B. Irene Tieleman
1. Seasonal variation in innate immunity is often attributed to either temporal environmental variation or to life history trade-offs that arise from specific annual cycle stages but decoupling them is difficult in natural populations. 2. Here, we effectively decouple seasonal environmental variation from annual cycle stage effects by exploiting cross-seasonal breeding and moult in the tropical Common Bulbul Pycnonotus barbatus. We test how annual cycle stage interacts with a key seasonal environmental variable, rainfall, to...

Data from: Local mate competition modifies the costs of mating in a mostly monandrous parasitoid wasp

Rebecca A. Boulton, Nicola Cook, E. V. Greenway, Georgina L. Glaser, Jade Green & David M. Shuker
The costs and benefits of mating are frequently measured in order to understand why females mate multiply. However, to separate the factors that initiate the evolution of polyandry (from monandry) from the factors that maintain it, we must ascertain how the environment changes the economics of mating. Here we show how context-dependent costs of mating can lead to the evolution of polyandry in a species that is monandrous in the wild, the parasitoid wasp Nasonia...

Data from: Coevolution of cultural intelligence, extended life history, sociality, and brain size in primates

Sally E. Street, Ana F. Navarrete, Simon M. Reader & Kevin N. Laland
Explanations for primate brain expansion and the evolution of human cognition and culture remain contentious despite extensive research. While multiple comparative analyses have investigated variation in brain size across primate species, very few have addressed why primates vary in how much they use social learning. Here, we evaluate the hypothesis that the enhanced reliance on socially transmitted behavior observed in some primates has coevolved with enlarged brains, complex sociality, and extended lifespans. Using recently developed...

Data from: Early development of vocal interaction rules in a duetting songbird

Karla D. Rivera-Cáceres, Esmeralda Quirós-Guerrero, Marcelo Araya-Salas, Christopher N. Templeton & William A. Searcy
Exchange of vocal signals is an important aspect of animal communication. Although birdsong is the premier model for understanding vocal development, the development of vocal interaction rules in birds and possible parallels to humans have been little studied. Many tropical songbirds engage in complex engage in vocal interactions in the form of duets between mated pairs. In some species duets show precise temporal coordination and follow rules (duet codes) governing which song type one bird...

Data from: Behavioural mechanisms of sexual isolation involving multiple modalities and their inheritance

Peter A. Moran, John Hunt, Christopher Mitchell, Michael G. Ritchie & Nathan W. Bailey
Speciation research dissects the genetics and evolution of reproductive barriers between parental species. Hybrids are the ‘gatekeepers’ of gene flow, so it is also important to understand the behavioural mechanisms and genetics of any potential isolation from their parental species. We tested the role of multiple behavioural barriers in reproductive isolation among closely related field crickets and their hybrids (Teleogryllus oceanicus and T. commodus). These species hybridise in the laboratory, but the behaviour of hybrids...

Mathematically modelled daily water saturation profiles for sites on the Namoi River floodplain in south-east Australia at different distances from the river

C.M. Evans, D.G. Dritschel & M.B. Singer
This dataset comprises mathematically modelled data of soil-water saturation, along vertical profiles, at 6 sites near the Namoi River, south-eastern Australia. The vertical profiles span the soil surface down to 10m deep, divided into 944 intervals. The 6 sites are located at different distances from the Namoi River and are split between 2 locations (Old Mollee and Yarral East). The distances from the river channel at each location are, Old Mollee: 50m, 140m and 320m,...

Data from: Sperm is a sexual ornament in rose bitterling

Carl Smith, Rowena Spence & Martin Reichard
In many taxa, odour cues mediate mating decisions. A key question is what these odours comprise, where they are produced, and what they signal. Using rose bitterling, fish that spawn in the gills of freshwater mussels, we investigated the role of sperm cues on female oviposition decisions using individuals of known MHC genotype. Male bitterling frequently released sperm prior to female oviposition and females responded with an increased probability of oviposition and released a greater...

Data from: Quantification and decomposition of environment-selection relationships

Darren Clarke Hunter, Josephine M. Pemberton, Jill G. Pilkington & Michael B. Morrissey
In nature, selection varies across time in most environments, but we lack an understanding of how specific ecological changes drive this variation. Ecological factors can alter phenotypic selection coefficients through changes in trait distributions or individual mean fitness, even when the trait-absolute fitness relationship remains constant. We apply and extend a regression-based approach in a population of Soay sheep (Ovis aries) and suggest metrics of environment-selection relationships that can be compared across studies. We then...

Data from: Assessing cetacean surveys throughout the Mediterranean Sea: a gap analysis in environmental space

Laura Mannocci, Jason J. Roberts, Patrick N. Halpin, Matthieu Authier, Olivier Boisseau, Mohamed Nejmeddine Bradai, Ana Cañadas, Carla Chicote, Léa David, Nathalie Di-Méglio, Caterina M. Fortuna, Alexandros Frantzis, Manel Gazo, Tilen Genov, Philip S. Hammond, Drasko Holcer, Kristin Kaschner, Dani Kerem, Giancarlo Lauriano, Tim Lewis, Giuseppe Notarbartolo Di Sciara, Simone Panigada, Juan Antonio Raga, Aviad Scheinin, Vincent Ridoux … & Joseph Vella
Heterogeneous data collection in the marine environment has led to large gaps in our knowledge of marine species distributions. To fill these gaps, models calibrated on existing data may be used to predict species distributions in unsampled areas, given that available data are sufficiently representative. Our objective was to evaluate the feasibility of mapping cetacean densities across the entire Mediterranean Sea using models calibrated on available survey data and various environmental covariates. We aggregated 302,481...

Data from: Incorporating non-equilibrium dynamics into demographic history inferences of a migratory marine species

Emma L. Carroll, Rachael Alderman, John L. Bannister, Martine Bérubé, Peter B. Best, Laura Boren, C. Scott Baker, Rochelle Constantine, Ken Findlay, Robert Harcourt, Louisiane Lemaire, Per J. Palsbøll, Nathalie J. Patenaude, Victoria J. Rowntree, Jon Seger, Debbie Steel, Luciano O. Valenzuela, Mandy Watson & Oscar E. Gaggiotti
Understanding how dispersal and gene flow link geographically separated populations over evolutionary history is challenging, particularly in migratory marine species. In southern right whales (SRWs, Eubalaena australis), patterns of genetic diversity are likely influenced by the glacial climate cycle and recent history of whaling. Here we use a dataset of mitochondrial DNA (mtDNA) sequences (n=1,327) and nuclear markers (17 microsatellite loci, n=222) from major wintering grounds to investigate circumpolar population structure, historical demography, and effective...

Data from: Model selection with overdispersed distance sampling data

Eric J. Howe, Stephen T. Buckland, Marie-Lyne Després-Einspenner & Hjalmar S. Kühl
1. Distance sampling (DS) is a widely-used framework for estimating animal abundance. DS models assume that observations of distances to animals are independent. Non-independent observations introduce overdispersion, causing model selection criteria such as AIC or AICc to favour overly complex models, with adverse effects on accuracy and precision. 2. We describe, and evaluate via simulation and with real data, estimators of an overdispersion factor (c ̂), and associated adjusted model selection criteria (QAIC) for use...

Data from: Social effects on fruit fly courtship song

Lucas Marie-Orleach, Nathan W. Bailey & Michael G. Ritchie
Courtship behaviour in Drosophila has often been described as a classic innate behavioural repertoire, but more recently extensive plasticity has been described. In particular, prior exposure to acoustic signals of con- or heterspecific males can change courtship traits in both sexes that are liable to be important in reproductive isolation. However, it is unknown whether male courtship song itself is socially plastic. We examined courtship song plasticity of two species in the Drosophila melanogaster subgroup....

Data from: Monogamy promotes altruistic sterility in insect societies

Nicholas G. Davies & Andy Gardner
Monogamy is associated with sibling-directed altruism in multiple animal taxa, including insects, birds, and mammals. Inclusive-fitness theory readily explains this pattern by identifying high relatedness as a promoter of altruism. In keeping with this prediction, monogamy should promote the evolution of voluntary sterility in insect societies if sterile workers make for better helpers. However, a recent mathematical population-genetics analysis failed to identify a consistent effect of monogamy on voluntary worker sterility. Here, we revisit that...

Data from: Opposing patterns of intraspecific and interspecific differentiation in sex chromosomes and autosomes

Peter A. Moran, Sonia Pascoal, Timothée Cezard, Judith E. Risse, Michael G. Ritchie & Nathan W. Bailey
Linking intraspecific and interspecific divergence is an important challenge in speciation research. X chromosomes are expected to evolve faster than autosomes and disproportionately contribute to reproductive barriers, and comparing genetic variation on X and autosomal markers within and between species can elucidate evolutionary processes that shape genome variation. We performed RADseq on a 16-population transect of two closely-related Australian cricket species, Teleogryllus commodus and T. oceanicus, covering allopatry and sympatry. This classic study system for...

Data from: Vestigial singing behaviour persists after the evolutionary loss of song in crickets

Will T. Schneider, Christian Rutz, Berthold Hedwig & Nathan W. Bailey
The evolutionary loss of sexual traits is widely predicted. Because sexual signals can arise from the coupling of specialised motor activity with morphological structures, disruption to a single component could lead to overall loss of function. Opportunities to observe this process and characterise any remaining signal components are rare, but could provide insight into the mechanisms, indirect costs, and evolutionary consequences of signal loss. We investigated the recent evolutionary loss of a long-range acoustic sexual...

Data from: Completing the hybridization triangle: the inheritance of genetic incompatibilities during homoploid hybrid speciation in ragworts (Senecio).

Adrian C. Brennan, Simon J. Hiscock & Richard J. Abbott
A new homoploid hybrid lineage needs to establish a degree of reproductive isolation from its parent species if it is to persist as an independent entity, but the role hybridization plays in this process is known in only a handful of cases. The homoploid hybrid ragwort species, Senecio squalidus, (Oxford ragwort) originated following the introduction of hybrid plants to the UK approximately 320 years ago. The source of the hybrid plants was from a naturally...

Arbuscular mycorrhizal fungi diversity data from a grassland microcosm experiment [NERC Soil Biodiversity Programme]

D. Johnson, P.J. Vandenkoornhuyse, J.R. Leake, L. Gilbert, , J.P Grime, J.P.W. Young & D.J. Read
These arbuscular mycorrhizal (AM) fungi diversity data were collected in 2000 as part of an investigation in an unfertilized limestone grassland soil supporting different synthesized vascular plant assemblages that had developed for three years. The experimental treatments comprised: bare soil; monocultures of the non mycotrophic sedge Carex flacca; monocultures of the mycotrophic grass Festuca ovina; and a species-rich mixture of four forbs, four grasses and four sedges. The experiment was undertaken in microcosms, set up...

Data from: Killer whales (Orcinus orca) in Iceland show weak genetic structure among diverse isotopic signatures and observed movement patterns

Sara B. Tavares, Filipa I.P. Samarra, Sonia Pascoal, Jeff A. Graves, Patrick J.O. Miller, Filipa I. P. Samarra & Patrick J. O. Miller
Local adaption through ecological niche specialization can lead to genetic structure between and within populations. In the Northeast Pacific, killer whales (Orcinus orca) of the same population have uniform specialized diets that are non-overlapping with other sympatric, genetically divergent and socially isolated killer whale ecotypes. However, killer whales in Iceland show intra-population variation of isotopic niches and observed movement patterns: some individuals appear to specialise on herring and follow it year-round while others feed upon...

Data from: A non-parametric maximum test for the Behrens–Fisher problem

Anke Welz, Graeme D. Ruxton & Markus Neuhäuser
Non-normality and heteroscedasticity are common in applications. For the comparison of two samples in the non-parametric Behrens–Fisher problem, different tests have been proposed, but no single test can be recommended for all situations. Here, we propose combining two tests, the Welch t test based on ranks and the Brunner–Munzel test, within a maximum test. Simulation studies indicate that this maximum test, performed as a permutation test, controls the type I error rate and stabilizes the...
