Data from: Postcopulatory sexual selection is associated with accelerated evolution of sperm morphology

Melissah Rowe, Tomas Albrecht, Emily Rebecca Alison Cramer, Arild Johnsen, Terje Laskemoen, Jason T. Weir & Jan T. Lifjeld
Rapid diversification of sexual traits is frequently attributed to sexual selection, though explicit tests of this hypothesis remain limited. Spermatozoa exhibit remarkable variability in size and shape, and studies report a correlation between sperm morphology (sperm length and shape) and sperm competition risk or female reproductive tract morphology. However, whether postcopulatory processes (e.g. sperm competition and cryptic female choice) influence the speed of evolutionary diversification in sperm form is unknown. Using passerine birds, we quantified...

Data from: The south-western Carpathians as a centre of ancient diversity of freshwater gammarid amphipods: insights from the Gammarus fossarum species complex

Denis Copilaş-Ciocianu & Adam Petrusek
Gammarus fossarum is a diverse species complex of epigean freshwater amphipods throughout Europe. Due to their poor dispersal capabilities and ubiquity, these crustaceans may serve as a model for investigating the influence of historical factors on the contemporary distribution and diversity patterns of freshwater macrozoobenthos. Here, we investigate the fine-scale phylogeographic structure of this complex across its range in the southwestern Carpathian Mountains, which comprises two areas that are geographically isolated from its main European...

Data from: Host association drives significant genetic divergence in the bed bug, Cimex lectularius

Warren Booth, Ondřej Balvín, Edward L. Vargo, Jitka Vilímová & Coby Schal
Genetic differentiation may exist among sympatric populations of a species due to long-term associations with alternative hosts (i.e., host-associated differentiation). While host-associated differentiation has been documented in several phytophagus insects, there are far fewer cases known in animal parasites. The bed bug, Cimex lectularius, a wingless insect, represents a potential model organism for elucidating the processes involved in host-associated differentiation in animal parasites with relatively limited mobility. In conjunction with the expansion of modern humans...

Data from: Phylogenetic marker development for target enrichment from transcriptome and genome skim data: the pipeline and its application in southern African Oxalis (Oxalidaceae)

Roswitha Schmickl, Aaron Liston, Vojtěch Zeisek, Kenneth Oberlander, Kevin Weitemier, Shannon C. K. Straub, Richard C. Cronn, Léanne L. Dreyer & Jan Suda
Phylogenetics benefits from using a large number of putatively independent nuclear loci and their combination with other sources of information, such as the plastid and mitochondrial genomes. To facilitate the selection of orthologous low-copy nuclear (LCN) loci for phylogenetics in nonmodel organisms, we created an automated and interactive script to select hundreds of LCN loci by a comparison between transcriptome and genome skim data. We used our script to obtain LCN genes for southern African...

Data from: Inbreeding depression of sperm traits in the zebra finch Taeniopygia guttata

Pavlína Opatová, Malika Ihle, Jana Albrechtová, Oldřich Tomášek, Bart Kempenaers, Wolfgang Forstmeier & Tomáš Albrecht
Inbreeding depression, or the reduction in fitness due to mating between close relatives, is a key issue in biology today. Inbreeding negatively affects many fitness-related traits, including survival and reproductive success. Despite this, very few studies have quantified the effects of inbreeding on vertebrate gamete traits under controlled breeding conditions using a full-sib mating approach. Here, we provide comprehensive evidence for the negative effect of inbreeding on sperm traits in a bird, the zebra finch...

Data from: Phylogenetic relatedness determined between antibiotic resistance and 16S rRNA genes in actinobacteria

Marketa Sagova-Mareckova, Dana Ulanova, Petra Sanderova, Marek Omelka, Zdenek Kamenik, Jana Olsovska & Jan Kopecky
Background: Distribution and evolutionary history of resistance genes in environmental actinobacteria provide information on intensity of antibiosis and evolution of specific secondary metabolic pathways at a given site. To this day, actinobacteria producing biologically active compounds were isolated mostly from soil but only a limited range of soil environments were commonly sampled. Consequently, soil remains an unexplored environment in search for novel producers and related evolutionary questions. Results: Ninety actinobacteria strains isolated at contrasting soil...

Data from: Phylogenetic divergences of the true bugs (Insecta: Hemiptera: Heteroptera), with emphasis on the aquatic lineages: the last piece of the aquatic insect jigsaw originated in the Late Permian/Early Triassic

Yan-Hui Wang, Ying Cui, Dávid Rédei, Petr Baňař, Qiang Xie, Pavel Štys, Jakob Damgaard, Ping-Ping Chen, Wen-Bo Yi, Ying Wang, Kai Dang, Chuan-Ren Li & Wen-Jun Bu
Heteroptera are among the most diverse hemimetabolous insects. Seven infraorders have been recognized within this suborder of Hemiptera. Apart from the well-established sister-group relationship between Cimicomorpha and Pentatomomorpha (= Terheteroptera), the two terminal lineages, the relationships among the other five infraorders are still controversial, of which three (Gerromorpha, Nepomorpha and Leptopodomorpha) are intimately connected to aquatic environments. However, the various and often conflicting available phylogeny hypotheses do not offer a clear background for a connection...

Data from: Context-dependence of maternal effects: testing assumptions of optimal egg size, differential- and sex-allocation models

Miloš Krist & Pavel Munclinger
If offspring develop in adverse conditions, the maternal component of their phenotypic variation might increase due to the stronger dependence of offspring traits on parental investment. This should result in increased parental investment to individual offspring, as assumed by the model of optimal egg size. The opposite pattern, i.e., stronger dependence of offspring fitness on parental investment and consequently larger parental investment under good conditions is assumed by both the theory of differential allocation if...

Data from: Nest as an extended phenotype signal of female quality in the great reed warbler

Václav Jelínek, Milica Požgayová, Marcel Honza & Petr Procházka
Extended phenotypes with signalling function are mostly restricted to animal taxa that use construction behaviour during courtship displays. However, they can be used also as post-mating signals of mate quality, allowing individuals to obtain reliable information about their partners. Nest size may have such a signalling function and a lot of indirect evidence supports this view. However, direct evidence based on an experimental approach is still widely missing. Here we test the role of nest...

Data from: Ecological differentiation, lack of hybrids involving diploids, and asymmetric gene flow between polyploids in narrow contact zones of Senecio carniolicus (syn. Jacobaea carniolica, Asteraceae)

Karl Hülber, Michaela Sonnleitner, Jan Suda, Jana Krejčíková, Peter Schönswetter, Gerald M. Schneeweiss & Manuela Winkler
Areas of immediate contact of different cytotypes offer a unique opportunity to study evolutionary dynamics within heteroploid species and to assess isolation mechanisms governing coexistence of cytotypes of different ploidy. The degree of reproductive isolation of cytotypes, i.e., the frequency of heteroploid crosses and subsequent formation of viable and (partly) fertile hybrids, plays a crucial role for the long-term integrity of lineages in contact zones. Here, we assessed fine-scale distribution, spatial clustering and ecological niches...

Data from: Reconstructing the invasion history of Heracleum persicum (Apiaceae) into Europe

Dilli P. Rijal, Torbjørn Alm, Šárka Jahodova, Hans K. Stenøein & Inger G. Alsos
Sparse, incomplete and inappropriate historical records of invasive species often hamper invasive species management interventions. Population genetic analyses of invaders might provide a suitable context for the identification of their source populations and possible introduction routes. Here, we describe the population genetics of Heracleum persicum Desf. ex Fisch and trace its route of introduction into Europe. Microsatellite markers revealed a significantly higher genetic diversity of H. persicum in its native range, and the loss of...

Data from: Static allometry of unicellular green algae: scaling of cellular surface area and volume in the genus Micrasterias (Desmidiales)

Jiri Neustupa
The surface area-to-volume ratio of cells is one of the key factors affecting fundamental biological processes and, thus, fitness of unicellular organisms. One of the general models for allometric increase in surface-to-volume scaling involves fractal-like elaboration of cellular surfaces. However, specific data illustrating this pattern in natural populations of the unicellular organisms have not previously been available. This study shows that unicellular green algae of the genus Micrasterias (Desmidiales) have positive allometric surface-to-volume scaling caused...

Data from: Scrimer: designing primers from transcriptome data

Libor Mořkovský, Jan Pačes, Jakub Rídl & Radka Reifová
With the rise of next-generation sequencing methods, it has become increasingly possible to obtain genomewide sequence data even for nonmodel species. Such data are often used for the development of single nucleotide polymorphism (SNP) markers, which can subsequently be screened in a larger population sample using a variety of genotyping techniques. Many of these techniques require appropriate locus-specific PCR and genotyping primers. Currently, there is no publicly available software for the automated design of suitable...

Data from: Repertoire-based individual acoustic monitoring of a migratory passerine bird with complex song as an efficient tool for tracking territorial dynamics and annual return rates

Tereza Petrusková, Iveta Pišvejcová, Anna Kinštová, Tomáš Brinke & Adam Petrusek
In field ecological and behavioural studies, it is often necessary to identify specific individuals. In birds, colour rings are frequently used to mark individuals; however, rings are often difficult to observe, especially in small species and dense habitats. Acoustic-based monitoring detecting individuals by their characteristic vocalization is a potentially suitable alternative, but this approach is challenging in species with complex songs. On the example of the Tree Pipit (Anthus trivialis), a small migratory passerine often...

Data from: How a haemosporidian parasite of bats gets around: the genetic structure of a parasite, vector and host compared

Fardo Witsenburg, Laura Clément, Ludovic Dutoit, Adrià López-Baucells, Jorge Palmeirim, Dino Scaravelli, Martin Ševčík, Nicolas Salamin, Jérôme Goudet, Philippe Christe & Igor Pavlinić
Parasite population structure is often thought to be largely shaped by that of its host. In the case of a parasite with a complex life cycle, two host species, each with their own patterns of demography and migration, spread the parasite. However, the population structure of the parasite is predicted to resemble only that of the most vagile host species. In this study we tested this prediction in the context of a vector-transmitted parasite. We...

Data from: Does hybridization with a widespread congener threaten the long-term persistence of the Eastern Alpine rare local endemic Knautia carinthiaca?

Martin Čertner, Filip Kolář, Peter Schönswetter & Božo Frajman
Interspecific hybridization, especially when regularly followed by backcrossing (i.e., introgressive hybridization), conveys a substantial risk for many endangered organisms. This is particularly true for narrow endemics occurring within distributional ranges of widespread congeners. An excellent example is provided by the plant genus Knautia (Caprifoliaceae): Locally endemic K. carinthiaca is reported from two isolated populations in southern Austria situated within an area predominantly occupied by widespread K. arvensis. While K. carinthiaca usually inhabits low-competition communities on...

Data from: Maternal-fetal genomic conflict and speciation: no evidence for hybrid placental dysplasia in crosses between two house mouse subspecies

Lucie Kropáčková, Jaroslav Piálek, Václav Gergelits, Jiří Forejt & Radka Reifová
Interspecific hybridization between closely related mammalian species, including various species of the genus Mus, is commonly associated with abnormal growth of the placenta and hybrid fetuses, a phenomenon known as hybrid placental dysplasia (HPD). The role of HPD in speciation is anticipated but still poorly understood. Here we studied placental and fetal growth in F1 crosses between four inbred mouse strains derived from two house mouse subspecies, Mus musculus musculus and M. m. domesticus. These...

Data from: The QRS (Quantification of Representative Sequences) pipeline for amplicon sequencing: case study on within-population ITS1 sequence variation in a microparasite infecting Daphnia

Enrique Gonzalez-Tortuero, Jakub Rusek, Adam Petrusek, Sabine Giessler, Dimitrios Lyras, Sonja Grath, Federico Castro-Monzon & Justyna Wolinska
Next generation sequencing (NGS) platforms are replacing traditional molecular biology protocols like cloning and Sanger sequencing. However, accuracy of NGS platforms has rarely been measured when quantifying relative frequencies of genotypes or taxa within populations. Here we developed a new bioinformatic pipeline (QRS) that pools similar sequence variants and estimates their frequencies in NGS data sets from populations or communities. We tested whether the estimated frequency of representative sequences, generated by 454 amplicon sequencing, differs...

Data from: Population structure of a microparasite infecting Daphnia: spatio-temporal dynamics

, , , , &
Background: Detailed knowledge of spatial and temporal variation in the genetic population structure of hosts and parasites is required for understanding of hostparasite coevolution. As hot-spots of contemporary coevolution in natural systems are difficult to detect and long-term studies are restricted to few systems additional population genetic data from various hostparasite systems may provide important insights into the topic. This is particularly true for parasites as these players have been under-investigated so far due to...

Data from: Decoding of baby calls: can adult humans identify the eliciting situation from emotional vocalizations of preverbal infants?

Jitka Lindová, Marek Špinka, Lenka Martinec Nováková & Lenka Nováková
Preverbal infants often vocalize in emotionally loaded situations, yet the communicative potential of these vocalizations is not well understood. The aim of our study was to assess how accurately adult listeners extract information about the eliciting situation from infant preverbal vocalizations. Vocalizations of 19 infants aged 5-10 months were recorded in 3 negative (Pain, Isolation, Demand for Food) and 3 positive (Play, Reunion, After Feeding) situations. The recordings were later rated by 333 adult listeners...
