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: Replicated latitudinal clines in reproductive traits of European and North American yellow dung flies

Stephanie S. Bauerfeind, Martin A. Schäfer, David Berger, Wolf U. Blanckenhorn & Charles W. Fox
Geographic variation in phenotypic traits is commonly correlated with spatial variation in the environment, e.g., seasonality and mean temperature, providing evidence that natural selection generates such patterns. In particular, both body size and egg size of ectothermic animals are commonly larger in northern climates, and temperature induces plastic responses in both traits. Size-independent egg quality can also vary with latitude, though this is rarely investigated. For the widespread yellow dung fly (Scathophaga stercoraria; Diptera: Scathophagidae),...

Data from: Interspecific transfer of parasites following a range-shift in Ficedula flycatchers

William Jones, Katarzyna Kulma, Staffan Bensch, Mariusz Cichoń, Anvar Kerimov, Miloš Krist, Toni Laaksonen, Juan Moreno, Pavel Munclinger, Fred Slater, Eszter Szöllősi, Marcel E. Visser, Anna Qvarnström & Fred M. Slater
Human-induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host-parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Two competing theories, the Enemy Release Hypothesis, where invading hosts escape their original parasites; and the Novel Weapon Hypothesis, where invading hosts bring new parasites that have detrimental effects on native hosts, have been described to predict...

Data from: Accounting for heteroscedasticity and censoring in chromosome partitioning analyses

Petri Kemppainen & Arild Husby
A fundamental assumption in quantitative genetics is that traits are controlled by many loci of small effect. Using genomic data, this assumption can be tested using chromosome partitioning analyses, where the proportion of genetic variance for a trait explained by each chromosome (h2c), is regressed on its size. However, as h2c-estimates are necessarily positive (censoring) and the variance increases with chromosome size (heteroscedasticity), two fundamental assumptions of ordinary least squares (OLS) regression are violated. Using...

Data from: Biochemical determinants of litter quality in 15 species of Sphagnum

Fia Bengtsson, Håkan Rydin & Tomáš Hájek
Background and aims: Sphagnum mosses are ecosystem engineers that create and maintain boreal peatlands. With unique biochemistry, waterlogging and acidifying capacities, they build up meters-thick layers of peat, reducing competition and impeding decomposition. We quantify within-genus differences in biochemical composition to make inferences about decay rates, related to hummock–hollow and fen–bog gradients and to phylogeny.Methods: We sampled litter from 15 Sphagnum species, abundant over the whole northern hemisphere. We used regression and Principal Components Analysis...

Data from: Neurocranial anatomy of an enigmatic Early Devonian fish sheds light on early osteichthyan evolution

Alice M. Clement, Benedict King, Sam Giles, Brian Choo, Per Ahlberg, Gavin C. Young, John A. Long & Per E Ahlberg
The skull of ‘Ligulalepis’ from the Early Devonian of Australia (AM-F101607) has significantly expanded our knowledge of early osteichthyan anatomy, but its phylogenetic position has remained uncertain. We herein describe a second skull of ‘Ligulalepis’ and present micro-CT data on both specimens to reveal novel anatomical features, including cranial endocasts. Several features previously considered to link ‘Ligulalepis’ with actinopterygians are now considered generalized osteichthyan characters or of uncertain polarity. The presence of a lateral cranial...

Data from: Developing reduced SNP assays from whole-genome sequence data to estimate introgression in an organism with complex genetic patterns, the Iberian honeybee (Apis mellifera iberiensis)

Dora Henriques, Melanie Parejo, Alain Vignal, David Wragg, Andreas Wallberg, Matthew Webster, M. Alice Pinto & Matthew T. Webster
The most important managed pollinator, the honeybee (Apis mellifera L.), has been subject to a growing number of threats. In Western Europe one such threat is large-scale introductions of commercial strains (C-lineage ancestry), which is leading to introgressive hybridization and even the local extinction of native honeybee populations (M-lineage ancestry). Here, we developed reduced assays of highly informative SNPs from 176 whole genomes to estimate C-lineage introgression in the most diverse and evolutionarily complex subspecies...

Data from: Ecological divergence plays an important role in strong but complex reproductive isolation in campions (Silene)

Sophie Karrenberg, Xiaodong Liu, Emelie Hallander, Adrien Favre, Joelle Herforth Rahmé & Alex Widmer
New species arise through the evolution of reproductive barriers between formerly interbreeding lineages. Yet, comprehensive assessments of potential reproductive barriers, which are needed to make inferences on processes driving speciation, are only available for a limited number of systems. In this study, we estimated individual and cumulative strengths of seven prezygotic and six postzygotic reproductive barriers between the recently diverged taxa Silene dioica (L.) Clairv. and S. latifolia Poiret using both published and new data....

Data from: Effects of interspecific coexistence on laying date and clutch size in two closely related species of hole‐nesting birds

Anders Pape Møller, Javier Balbontin, André A. Dhondt, Vladimir Remeš, Frank Adriaensen, Clotilde Biard, Jordi Camprodon, Mariusz Cichoń, Blandine Doligez, Anna Dubiec, Marcel Eens, Tapio Eeva, Anne E. Goodenough, Andrew G. Gosler, Lars Gustafsson, Philipp Heeb, Shelley A. Hinsley, Staffan Jacob, Rimvydas Juškaitis, Toni Laaksonen, Bernard Leclercq, Bruno Massa, Tomasz D. Mazgajski, Rudi G. Nager, Jan-Åke Nilsson … & Ruedi G. Nager
Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole‐nesting taxa, constitutes a classic example of species co‐occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across...

Data from: The independent and combined effects of floral traits distinguishing two pollination ecotypes of a moth-pollinated orchid

Judith Trunschke, Nina Sletvold & Jon Agren
Identifying traits and agents of selection involved in local adaptation is important for understanding population divergence. In southern Sweden, the moth-pollinated orchid Platanthera bifolia occurs as a woodland and a grassland ecotype that differ in dominating pollinators. The woodland ecotype is taller (expected to influence pollinator attraction) and produces flowers with longer spurs (expected to influence efficiency of pollen transfer) compared to the grassland ecotype. We examined whether plant height and spur length affect pollination...

Data from: Landscape permeability and individual variation in a dispersal-linked gene jointly determine genetic structure in the Glanville fritillary butterfly

Michelle F. DiLeo, Arild Husby & Marjo Saastamoinen
There is now clear evidence that species across a broad range of taxa harbour extensive heritable variation in dispersal. While studies suggest that this variation can facilitate demographic outcomes such as range expansion and invasions, few have considered the consequences of intraspecific variation in dispersal for the maintenance and distribution of genetic variation across fragmented landscapes. Here we examine how landscape characteristics and individual variation in dispersal combine to predict genetic structure using genomic and...

Data from: RPASE: individual based allele-specific expression detection without prior knowledge of haplotype phase

Mi Wang, Severin Uebbing, Yudi Pawitan & Douglas G. Scofield
Variation in gene expression is believed to make a significant contribution to phenotypic diversity and divergence. The analysis of allele-specific expression (ASE) can reveal important insights into gene expression regulation. We developed a novel method called RPASE (Read-backed Phasing-based ASE detection) to test for genes that show ASE. With mapped RNA-seq data from a single individual and a list of SNPs from the same individual as the only input, RPASE is capable of aggregating information...

Data from: Host diet mediates a negative relationship between abundance and diversity of Drosophila gut microbiota

Berra Erkosar, Erika Yashiro, Felix Zajitschek, Urban Friberg, Alexei A. Maklakov, Jan Roelof Van Der Meer & Tadeusz J. Kawecki
Nutrient supply to ecosystems has major effects on ecological diversity, but it is unclear to what degree the shape of this relationship is general versus dependent on the specific environment or community. Although the diet composition in terms of the source or proportions of different nutrient types is known to affect gut microbiota composition, the relationship between the quantity of nutrients supplied and the abundance and diversity of the intestinal microbial community remains to be...

Data from: Geographic clines in wing morphology relate to colonization history in New World but not Old World populations of yellow dung flies

Martin A. Schaefer, David Berger, Patrick T. Rohner, Anders Kjaersgaard, Stephanie S. Bauerfeind, Frédéric Guillaume, Charles W. Fox, Wolf Blanckenhorn & Wolf U. Blanckenhorn
Geographic clines offer insights about putative targets and agents of natural selection as well as tempo and mode of adaptation. However, demographic processes can lead to clines that are indistinguishable from adaptive divergence. Using the widespread yellow dung fly Scathophaga stercoraria (Diptera: Scathophagidae), we examine quantitative genetic differentiation (QST) of wing shape across North America, Europe and Japan, and compare this differentiation with that of ten microsatellites (FST). Morphometric analyses of 28 populations reared at...

Data from: Convergent morphology in Alpinieae (Zingiberaceae): recircumscribing Amomum as a monophyletic genus

Hugo De Boer, Mark Newman, Axel Dalberg Poulsen, A. Jane Droop, Tomas Fer, Le Thi Thu Hien, Kristyna Hlavata, Vichith Lamxay, James E. Richardson, Karin Steffen & Jana Leong-Škorničková
The tropical ginger genus Amomum (Zingiberaceae) has always posed challenges for classification based on morphological characters. Previous molecular phylogenetic studies showed Amomum to be paraphyletic but limited sampling and absence of the data of the type Amomum subulatum made it impossible to resolve the paraphyly and make nomenclatural changes. Here, Amomum is further investigated in a multi-marker phylogenetic framework using matK and nrITS including multiple accessions of the type, the genus Elettaria and additional accessions...

Data from: Bayesian phylogenetic analysis of combined data

Johan A. A. Nylander, Fredrik Ronquist, John P. Huelsenbeck & Joséluis Nieves-Aldrey
The recent development of Bayesian phylogenetic inference using Markov chain Monte Carlo (MCMC) techniques has facilitated the exploration of parameter-rich evolutionary models. At the same time, stochastic models have become more realistic (and complex) and have been extended to new types of data, such as morphology. Based on this foundation, we developed a Bayesian MCMC approach to the analysis of combined data sets and explored its utility in inferring relationships among gall wasps based on...

Data from: Grazers affect selection on inflorescence height both directly and indirectly and effects change over time

Michel Thomann, Johan Ehrlén & Jon Ågren
Selection mediated by one biotic agent will often be modified by the presence of other biotic interactions, and the importance of such indirect effects might change over time. We conducted an 11-year field experiment to test the prediction that large grazers affect selection on floral display of the dimorphic herb Primula farinosa not only directly through differential grazing damage, but also indirectly by affecting vegetation height and thereby selection mediated by pollinators and seed predators....

Data from: Enhancing the steroid sulfatase activity of the arylsulfatase from Pseudomonas aeruginosa

Dimanthi Roshika Uduwela, Anna Pabis, Bradley J. Stevenson, Shina C. L. Kamerlin & Malcolm D. McLeod
Steroidal sulfate esters play a central role in many physiological processes. They serve as the reservoir for endogenous sex hormones and form a significant fraction of the steroid metabolite pool. The analysis of steroid sulfates is thus essential in fields such as medical science and sports drug testing. Although the direct detection of steroid sulfates can be readily achieved using liquid chromatography-mass spectrometry, many analytical approaches, including gas chromatography-mass spectrometry, are hampered due to the...

Data from: Gut evolution in early Cambrian trilobites and the origin of predation on infaunal macroinvertebrates: evidence from muscle scars in Mesolenellus.

Rudy Lerosey-Aubril & John S. Peel
Trilobites are particularly common Cambrian fossils, but their trophic impact on the rapidly evolving marine ecosystems of that time is difficult to assess, due to uncertainties on how diverse their feeding habits truly were. Gut anatomy might help to constrain inferences on trilobite feeding ecology, but preservation of digestive organs is exceedingly rare. Muscle scars on the glabella, known as ‘frontal auxiliary impressions’ (FAIs), have been interpreted as evidence of the evolution of a pouch-like...

Data from: Optimal sperm length for high siring success depends on forehead patch size in collared flycatchers

Murielle Ålund, Siri Persson Schmiterlöw, S. Eryn McFarlane & Anna Qvarnström
Dominance over rivals, sexual attractiveness and highly efficient ejaculates are three important contributors of male fertilization success but theories about how primary and secondary sexual characters may co-evolve largely remain to be tested. We investigated how variation in a sexual signal (forehead patch size) and in sperm morphology jointly affected siring success of 70 males in a natural population of collared flycatchers. We show that the optimal sperm length to attain high relative fertilization success...

Data from: Host‐derived population genomics data provides insights into bacterial and diatom composition of the killer whale skin

Rebecca Hooper, Jaelle C. Brealey, Tom Van Der Valk, Antton Alberdi, John W. Durban, Holly Fearnbach, Kelly M. Robertson, Robin W. Baird, M. Bradley Hanson, Paul Wade, M. Thomas P. Gilbert, Philip A. Morin, Jochen B. W. Wolf, Andrew D. Foote, Katerina Guschanski & Phillip A. Morin
Recent exploration into the interactions and relationship between hosts and their microbiota has revealed a connection between many aspects of the host's biology, health and associated micro‐organisms. Whereas amplicon sequencing has traditionally been used to characterize the microbiome, the increasing number of published population genomics data sets offers an underexploited opportunity to study microbial profiles from the host shotgun sequencing data. Here, we use sequence data originally generated from killer whale Orcinus orca skin biopsies...

Data from: Parallel plumage color evolution and introgressive hybridization in wheatears

Manuel Schweizer, Vera Warmuth, Niloofar Alaei Kakhki, Mansour Aliabadian, Marc Förschler, Hadoram Shirihai, Alexander Suh & Reto Burri
Genetic and phenotypic mosaics, in which various phenotypes and different genomic regions show discordant patterns of species or population divergence, offer unique opportunities to study the role of ancestral and introgressed genetic variation in phenotypic evolution. Here, we investigated the evolution of discordant phenotypic and genetic divergence in a monophyletic clade of four songbird taxa – pied wheatear (O. pleschanka), Cyprus wheatear (O. cypriaca), and western and eastern subspecies of black-eared wheatear (O. h. hispanica...

Data from: Sexual selection, environmental robustness and evolutionary demography of maladapted populations: a test using experimental evolution in seed beetles

Ivain Martinossi-Allibert, Emma Thilliez, Goran Arnqvist & David Berger
Whether sexual selection impedes or aids adaptation has become an outstanding question in times of rapid environmental change and parallels the debate about how the evolution of individual traits impacts on population dynamics. The net effect of sexual selection on population viability results from a balance between genetic benefits of “good genes” effects and costs of sexual conflict. Depending on how these facets of sexual selection are affected under environmental change, extinction of maladapted populations...

Data from: The genetic variance but not the genetic covariance of life-history traits changes towards the north in a time-constrained insect

Szymon Sniegula, Maria J. Golab, Szymon M. Drobniak & Frank Johansson
Seasonal time constraints are usually stronger at higher than lower latitudes and can exert strong selection on life history traits and the correlations among these traits. To predict the response of life history traits to environmental change along a latitudinal gradient, information must be obtained about genetic variance in traits and also genetic correlation between traits, i.e., the genetic variance-covariance matrix, G. Here, we estimated G for key life history traits in an obligate univoltine...

Data from: Mollusks from the upper Shackleton Limestone (Cambrian Series 2), Central Transantarctic Mountains, East Antarctica

Thomas M. Claybourn, Sarah M. Jacquet, Christian B. Skovsted, Timothy P. Topper, Lars E. Holmer & Glenn A. Brock
An assemblage of Cambrian Series 2, Stages 3–4 conchiferan mollusks from the Shackleton Limestone, Transantarctic Mountains, East Antarctica is formally described and illustrated. The fauna includes one bivalve, one macromollusk and ten micromollusks, including the first description of the species Xinjispira simplex outside North China. The new fauna shows some similarity to previously described micromollusks from lower Cambrian glacial erratics from the Antarctic Peninsula. The fauna, mainly composed of steinkerns, is relatively low diversity, but...
