Premise of the study: Hybrid capture with high-throughput sequencing (Hyb-Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family-specific Hyb-Seq method and the outcomes of different phylogenetic analyses are assessed. Methods: Hyb-Seq data from 112 Asteraceae samples were organized into groups at different taxonomic levels (tribe, genus, and species). For each group, datasets of non-paralogous loci were built and proportions of parsimony informative characters estimated. The impacts of the analyzing alternative...

Premise of the Study The origin of allopolyploids is believed to shape their evolutionary potential, ecology and geographical ranges. Morphologically distinct apomictic types sharing the same parental species belong to the most challenging groups of polyploids. We evaluated the origins and variation of two triploid taxa (Hieracium pallidiflorum, H. picroides) presumably derived from the same diploid parental pair (H. intybaceum, H. prenanthoides). Methods We used a suite of approaches ranging from morphological, phylogenetic (three unlinked...

Methods: In this single centre cross-sectional study a total of 246 patients with axSpA fulfilling the imaging arm of ASAS classification criteria were recruited. A total of 140 patients were diagnosed as nr-axSpA, and 106 patients had AS. Sociodemographic characteristics, disease manifestations, clinical and laboratory disease activity and their differences between subsets were analysed. P values below 0.05 with...

Singing behind the stage: thrush nightingales produce more variable songs on their wintering grounds

Abel Souriau, Nicole Geberzahn, Vladimir V Ivanitskii, Irina M Marova, Jana Vokurková, Radka Reifová, Jiři Reif & Tereza Petrusková
The songs of migratory passerine birds have a key role in mate attraction and territory defence during the breeding season. Many species also sing on their wintering grounds, but the function of this behaviour remains unclear. One possible explanation, proposed by the song improvement hypothesis, is that the birds take advantage of this period to develop their singing skills for the next breeding season. If so, non-breeding songs should reflect features of an early phase...

Data from: Scrutinizing assortative mating in birds

Daiping Wang, Wolfgang Forstmeier, Mihai Valcu, Niels Dingemanse, Martin Bulla, Christiaan Both, Renée A. Duckworth, Lynna Marie Kiere, Patrik Karell, Tomáš Albrecht & Bart Kempenaers
It is often claimed that pair bonds preferentially form between individuals that resemble one another. Such assortative mating appears to be widespread throughout the animal kingdom. Yet it is unclear whether the apparent ubiquity of assortative mating arises primarily from mate choice (‘like attracts like’) which can be constrained by same-sex competition for mates, from spatial or temporal separation, or from observer, reporting, publication or search bias. Here, based on a conventional literature search, we...

Data from: Earthworms affect growth and competition between ectomycorrhizal and arbuscular mycorrhizal plants

Jan Frouz, Jabbar Moradi, David Püschel & Jana Rydlová
Previous research showed that during intermediate stages of primary succession, when vegetation is dominated by ectomycorrhizal (EcM) shrubs and trees, site colonization by earthworms substantially alters plant communities. Research has also shown that EcM shrubs and trees suppress arbuscular mycorrhizal (AM) plants in the understory. To determine whether earthworm activity reduces this asymmetric competition, we conducted a full factorial laboratory experiment in which we grew EcM Betula pendula and AM Tripleurospermum inodorum, together or apart,...

Seasonal shifts of biodiversity patterns and species’ elevation ranges of butterflies and moths along a complete rainforest elevational gradient on Mount Cameroon

Vincent Maicher, Szabolcs Sáfián, Mercy Murkwe, Sylvain Delabye, Łukasz Przybyłowicz, Pavel Potocký, Ishmeal N. Kobe, Štěpán Janeček, Jan E. J. Mertens, Eric B. Fokam, Tomasz Pyrcz, Jiří Doležal, Jan Altman, David Hořák, Konrad Fiedler & Robert Tropek
Aim Temporal dynamics of biodiversity along tropical elevational gradients are unknown. We studied seasonal changes of Lepidoptera biodiversity along the only complete forest elevational gradient in the Afrotropics. We focused on shifts of species richness patterns, seasonal turnover of communities, and seasonal shifts of species’ elevational ranges, the latter often serving as an indicator of the global change effects on mountain ecosystems. Location Mount Cameroon, Cameroon. Taxon Butterflies and moths (Lepidoptera) Methods We quantitatively sampled...

Data from: Wild boar (Sus scrofa) increases species diversity of semi-dry grassland: field experiment with simulated soil disturbances

Eva Horčičková, Josef Brůna & Jaroslav Vojta
Background Foraging activities of wild boar (Sus scrofa) create small-scale soil disturbances in many different vegetation types. Rooting alters species composition by opening niches for less-competitive plants and as a recurrent factor becomes a part of the community disturbance regime. Vegetation responses to wild boar disturbance have mostly been studied in the boar’s non-native range or in native forest, rather than in open habitats in the native range. We investigate the response of open European...

Data from: Availability of food resources and habitat structure shape the individual‐resource network of a neotropical marsupial

Nicholas F. De Camargo, Hernani F.M. De Oliveira, Juliana F. Ribeiro, Amabilio J.A. De Camargo & Emerson M. Vieira
1. Spatial and temporal variation in networks has been reported in different studies. However, the many effects of habitat structure and food-resource availability variation on network structures have remained poorly investigated, especially in individual-based networks. This approach can shed light on individual specialization of resource use and how habitat variations shape trophic interactions. 2. To test hypotheses related to habitat variability on trophic interactions, we investigated seasonal and spatial variation in network structure of four...

Data from: Automated taxonomic identification of insects with expert-level accuracy using effective feature transfer from convolutional networks

Miroslav Valan, Karoly Makonyi, Atsuto Maki, Dominik Vondracek & Fredrik Ronquist
Rapid and reliable identification of insects is important in many contexts, from the detection of disease vectors and invasive species to the sorting of material from biodiversity inventories. Because of the shortage of adequate expertise, there has long been an interest in developing automated systems for this task. Previous attempts have been based on laborious and complex handcrafted extraction of image features, but in recent years it has been shown that sophisticated convolutional neural networks...

Ecological fitting is a sufficient driver of tight interactions between sunbirds and ornithophilous plants

Stepan Janecek
1. Plant-bird pollination interactions evolved independently on different continents. Specific adaptations can lead to their restriction when potential partners from distant evolutionary trajectories come into contact. Alternatively, these interactions can be enabled by convergent evolution and subsequent ecological fitting. 2. We studied the interactions between New World plants from the genus Heliconia, Asian plants of genus Etlingera and African sunbirds on a local farm in Cameroon. Heliconia evolved together with hummingbirds and Etlingera spp. with...

Extraordinary variation in a simple song: No geographical patterns in initial phrase variation of the Yellowhammer, a passerine with pronounced dialects

Sharina Van Boheemen, Lucie Diblíková, Jana Bílková, Adam Petrusek & Tereza Petrusková
Geographical variation of birdsong is used to study various topics from cultural evolution to mechanisms responsible for reproductive barriers or song acquisition. In species with pronounced dialects, however, patterns of variation in nondialect parts of the song are usually overlooked. We focused on the individually variable initial phrase of the song of the Yellowhammer (Emberiza citrinella), a common Palearctic passerine which became a model species for dialect research. We used a quantitative method to compare...

Data from: Selection on multiple sexual signals in two Central- and Eastern-European populations of the barn swallow

Peter Laszlo Pap, Attila Fülöp, Marie Adamkova-Kotasova, Jaroslav Cepak, Romana Michalkova, Rebecca J. Safran, Alexandru N. Stermin, Oldrich Tomasek, Csongor I. Vágási, Orsolya Vincze, Matthew R. Wilkins & Tomas Albrecht
Variation in intensity and targets of sexual selection on multiple traits has been suggested to play a major role in promoting phenotypic differentiation between populations, although the divergence in selection may depend on year, local conditions or age. In this study, we quantified sexual selection for two putative sexual signals across two Central and East European barn swallow (Hirundo rustica rustica) populations from Czech Republic and Romania over multiple years. We then related these differences...

Data from: Changing disturbance-diversity relationships in temperate ecosystems over the past 12000 years

Petr Kuneš, Vojtěch Abraham & Tomáš Herben
1. Disturbances such as fires and grazing have major impacts on biodiversity. While it has been suggested that species richness is highest with intermediate levels of disturbance, currently there is no consensus due to an absence of data covering large temporal and spatial scales. 2. We developed a new method to examine disturbance-diversity relationships (DDR) using sedimentary pollen data linked with species' disturbance ecology. We reconstructed disturbance and diversity dynamics in the region of the...

Data from: Female solo song and duetting are associated with different territoriality in songbirds

Peter Mikula, Anna Tószögyová, David Hořák, Tereza Petrusková, David Storch & Tomas Albrecht
Recently, there has been an increased effort to unravel selective factors behind female song evolution in songbirds. Female birds which produce songs may sing either solo or in duets; although the two vocal performances likely evolved through different selection forces and mechanisms, the majority of large-scale studies to date have focused only on duetting or female song in general (pooling female solo song and duetting into a single category). Hence, here we estimate the effect...
