Termite dispersal is influenced by their diet

Simon Hellemans, Jan Šobotník, Gilles Lepoint, Martin Mihaljevič, Yves Roisin & Thomas Bourguignon
Termites feed on vegetal matter at various stages of decomposition. Lineages of wood- and soil-feeding termites are distributed across terrestrial ecosystems located between 45°N and 45°S of latitude, a distribution they acquired through many transoceanic dispersal events. While wood-feeding termites often live in the wood on which they feed and are efficient at dispersing across oceans by rafting, soil-feeders are believed to be poor dispersers. Therefore, their distribution across multiple continents requires an explanation. Here,...

Stressful daylight: Differences in diel rhythmicity between albino and pigmented fish

Tereza Valchářová, Ondřej Slavík, Pavel Horký, Alžběta Stará, Iveta Hrušková, Matúš Maciak, Michal Pešta & Josef Velíšek
In laboratory experiments, variously colored strains of animals, including those with albino phenotypes, are commonly used. The melanocortin theory suggests, however, that coloration phenotypes alter animal physiology and behavior. Animals with the albino phenotype show photoreceptor degradation associated with lowered visual accuracy, escape reactions, etc., presumably accompanied by prevailing nocturnal activity and lowered aggressiveness. This assumption was tested in small groups of albino and pigmented European catfish, Silurus glanis, during the circadian cycle. The frequency...

Effects of soil conditioning, root and shoot litter addition interact to determine the intensity of plant-soil feedback (dataset)

Anna Aldorfová
Plant-soil feedback (PSF) is recognized as an important mechanism shaping plant communities and determining plant abundance and coexistence. Under natural conditions, plants affect the outcome of plant-soil interactions simultaneously by conditioning the soil by living roots and by litter inputs into the soil. However, most experimental studies only focus on one of the pathways, which limits our understanding of PSF in the field. Here, we simultaneously explored the effect of soil conditioning by living roots...

Molecular evolution and depth-related adaptations of rhodopsin in the adaptive radiation of cichlid fishes in Lake Tanganyika

Virginie Ricci, Fabrizia Ronco, Zuzana Musilova & Walter Salzburger
The visual sensory system is essential for animals to perceive their environment and is thus under strong selection. In aquatic environments, light intensity and spectrum differ primarily along a depth gradient. Rhodopsin (RH1) is the only opsin responsible for dim-light vision in vertebrates and has been shown to evolve in response to the respective light conditions, including along a water depth gradient in fishes. In this study, we examined the diversity and sequence evolution of...

Data from: Local population collapse of Ross's and lesser snow geese driven by failing recruitment and diminished philopatry

Mitch Weegman, Ray Alisauskas, Dana Kellett, Qing Zhao, Scott Wilson & Tomas Telensky
We estimated survival and per capita production of young, as well as emigration and immigration, from 1997 to 2017 in Ross's goose Anser rossii and lesser snow goose Anser caerulescens caerulescens, which are sympatric species of migratory birds that nest in the central Canadian Arctic at one of the largest breeding colonies in North America. We formed age-structured integrated population models for each species that jointly analyzed live and dead encounter data as well as...

Comparative analysis of passerine feather traits: data and script

Tomas Albrecht & Krystof Horak
Tropical bird species are characterised by a comparatively slow pace of life, being predictably different from their temperate zone counterparts in their investments in growth, survival and reproduction. In birds, the development of functional plumage is often considered energetically demanding investment, with consequences on individual fitness and survival. However, current knowledge of interspecific variation in feather growth patterns is mostly based on species of the northern temperate zone. We evaluated patterns in tail feather growth...

Exon-based phylogenomics and the relationships of African cichlids: Tackling the challenges of reconstructing phylogenies with repeated rapid radiations

Viviana Astudillo-Clavijo, Melanie Stiassny, Katriina Ilves, Zuzana Musilova, Walter Salzburger & Hernán López-Fernández
African cichlids (subfamily: Pseudocrenilabrinae) are among the most diverse vertebrates, and their propensity for repeated rapid radiation has made them a celebrated model system in evolutionary research. Nonetheless, despite numerous studies, phylogenetic uncertainty persists, and riverine lineages remain comparatively underrepresented in higher-level phylogenetic studies. Heterogeneous gene histories resulting from incomplete lineage sorting (ILS) and hybridization are likely sources of uncertainty, especially during episodes of rapid speciation. We investigate relationships of Pseudocrenilabrinae and its close relatives...

Data from: Demographic correction – a tool for inference from individuals to populations

Adam Klimeš, Jitka Klimešová, Zdeněk Janovský & Tomáš Herben
Estimation of responses of organisms to their environment using experimental manipulations, and comparison of such responses across sets of species, is one of the primary tools in ecology research. The most common approach is to compare response of a single life stage of species to an environmental factor and use this information to draw conclusions about population dynamics of these species. Such approach ignores the fact that interspecific fitness differences measured at a single life...

Interspecific differences in root foraging precision cannot be directly inferred from species' mycorrhizal status or fine root economics

Pavlína Stiblíková, Adam Klimeš, James Cahill, Tomáš Koubek & Martin Weiser
Nutrient acquisition in plants can be represented by a suite of intercorrelated root traits such as root diameter, nitrogen content, root tissue density, and specific root length. However, it is unclear how a plant's ability to precisely forage for nutrients in a heterogeneous soil environment (i.e., the precision of placing roots into nutrient-rich areas) relates to these traits. Mycorrhizal symbiosis also affects the relationship between the fine root traits and root foraging precision because fungal...

Climate and land-use effects on dung beetle assemblages

Jana Englmeier, Christian Von Hoermann, Daniel Rieker, Eric M. Benbow, Caryl Benjamin, Ute Fricke, Cristina Ganuza, Maria Haensel, Tomáš Lackner, Oliver Mitesser, Sarah Redlich, Rebekka Riebl, Sandra Rojas-Botero, Thomas Rummler, Jörg-Alfred Salamon, David Sommer, Ingolf Steffan-Dewenter, Cynthia Tobisch, Johannes Uhler, Lars Uphus, Jie Zhang & Jörg Müller
This dataset contains data from a field study conducted in 2019 and described in the paper "Dung beetle diversity is mainly affected by land use, while community specialization is driven by climate" by Englmeier et al. To test the effects of land use and climate on α-diversity, local community specialization (H2'), and γ-diversity of dung beetles, we used pitfall traps baited with four different dung types at 114 study sites, distributed over a spatial extent...

Microbial community from species rich meadow supports plant specialists during meadow restoration

Masoud M. Ardestani, Masoud Ardestani, Ondrej Mudrák, Jakub Vicena, Daquan Sun, Hana Vesela & Jan Frouz
Soil properties and soil microbial communities can greatly affect plant communities, especially in disturbed ecosystems. However, their relative contribution to the final effect on plants has rarely been assessed. We manipulated the soil microbial community in microcosms by inoculating sterilized soils originating from preserved species-rich meadow and a restored meadow with a high and low diversity of microbial inoculum (manipulated by dilution of microbial community extract) from those soils in full factorial manner, yielding eight...

Sequestration of defenses against predators drives specialized host plant associations in preadapted milkweed bugs (Heteroptera: Lygaeinae)

Georg Petschenka, Rayko Halitschke, Tobias Züst, Anna Roth, Sabrina Stiehler, Linda Tenbusch, Christoph Hartwig, Juan Francisco Moreno Gámez, Robert Trusch, Jürgen Deckert, Kateřina Chalušová, Andreas Vilcinskas & Alice Exnerová
Host plant specialization across herbivorous insects varies dramatically, but while the molecular mechanisms of host-plant adaptations are increasingly known, we often lack a comprehensive understanding of the selective forces that favor specialization. The milkweed bugs (Heteroptera: Lygaeinae) are engaged in ancestrally specialized associations with plants of the Apocynaceae from which they commonly sequester cardiac glycosides for defense, facilitated by resistant Na+/K+-ATPases and adaptations for transport, storage and discharge of toxins. Here, we show that three...

Traits and ecological space availability predict avian densities at the country scale of the Czech Republic

David Horak, Javier Rivas, Jan Farkac & Jiri Reif
Species geographical distributions and abundances are a central focus of current ecological research. Although multiple studies have been conducted on their elucidation, some important information are still missing. One of them is the knowledge of ecological traits of species responsible for the population density variations across geographical (i.e. total physical area) and ecological spaces (i.e. suitable habitat area). This is crucial for understanding how ecological specialisation shapes the geographical distribution of species, and provides key...

Data from: Diversity of land snail tribe Helicini (Gastropoda: Stylommatophora: Helicidae): where do we stand after 20 years of sequencing mitochondrial markers?

Ondřej Korábek, Lucie Juřičková & Adam Petrusek
Sequences of mitochondrial genes revolutionized the understanding of animal diversity and continue to be an important tool in biodiversity research. In the tribe Helicini, a prominent group of the western Palaearctic land snail fauna, mitochondrial data accumulating since the 2000s helped to newly delimit genera, inform species-level taxonomy, and reconstruct past range dynamics. We combined the published data with own unpublished sequences and provide a detailed overview of what they revealed about the diversity of...

Shoot senescence in perennials of seasonal habitats: Comparative analysis of a large set of species

Tomas Herben, Tereza Mašková, Kristyna Hoskova & Tomas Koubek
1. Senescence in plants is a hierarchical process affecting all their body parts from cells to whole organisms. Here we aim to fill the gap between the existing knowledge on leaf senescence and rapidly accumulating evidence on whole-plant senescence by addressing patterns and drivers of shoot senescence of herbaceous plants. This is a key process that determines photosynthetic gain late in the season and economy of soil-borne nutrients in seasonal climate. 2. We present a...

A monograph of Aspergillus section Candidi

Kateřina Glässnerová, František Sklenář, Željko Jurjević, Jos Houbraken, Takashi Yaguchi, Cobus M. Visagie, Josepa Gené, João P. Z. Siqueira, Alena Kubátová, Miroslav Kolařík & Vit Hubka
Aspergillus section Candidi encompasses white- or yellow-sporulating species mostly isolated from indoor and cave environments, food, feed, clinical material, soil and dung. Their identification is non-trivial due to largely uniform morphology. This study aims to re-evaluate the species boundaries in the section Candidi and present an overview of all existing species along with information on their ecology. For the analyses, we assembled a set of 113 strains with diverse origin. For the molecular analyses, we...

Population changes in a whale breeding ground revealed by citizen science noninvasive genetics unique microsatellite profiles of southern right whales

Petra Neveceralova, Emma Carroll, Debbie Steel, Els Vermeulen, Simon Elwen & Pavel Hulva
Historical exploitation, and a combination of current anthropogenic impacts, such as climate change and habitat degradation, impact the population dynamics of marine mammalian megafauna. Right whales (Eubalaena spp.) are large cetaceans recovering from hunting, whose reproductive and population growth rate appear to be impacted by climate change. We apply noninvasive genetic methods to monitor southern right whale (E. australis, SRW) and test the application of noninvasive genetics to minimise the observer effects on the population....

Host-driven subspeciation in hedgehog fungus, Trichophyton erinacei, an emerging cause of human dermatophytosis

Adéla Čmoková, Miroslav Kolařík, Jacques Guillot, Veronica Risco-Castillo, Francisco Javier Cabañes, Pietro Nenoff, Silke Uhrlaß, Radim Dobiáš, Naďa Mallátová, Takashi Yaguchi, Rui Kano, Ivana Kuklová, Pavlína Lysková, Karel Mencl, Petr Hamal, Vit Hubka & Andrea Peano
Trichophyton erinacei is a main cause of dermatophytosis in hedgehogs and is increasingly reported from human infections worldwide. This pathogen was originally described in the European hedgehog (Erinaceus europaeus) but is also frequently found in the African four-toed hedgehog (Atelerix albiventris), a popular pet animal worldwide. Little is known about the taxonomy and population genetics of this pathogen despite its increasing importance in clinical practice. Notably, whether there are different populations or even cryptic species...

Data from: Pervasive introgression during rapid diversification of the European mountain genus Soldanella (L.) (Primulaceae)

Marek Slovak
Hybridization is a key mechanism involved in lineage diversification and speciation, especially in ecosystems that experienced repeated environmental oscillations. Recently radiated plant groups, which have evolved in mountain ecosystems impacted by historical climate change provide an excellent model system for studying the impact of gene flow on speciation. We combined organellar (whole plastome) and nuclear genomic data (RAD-seq) with a cytogenetic approach (rDNA FISH) to investigate the effects of hybridization and introgression on evolution and...
