Data from: Conquest of the deep, old and cold: an exceptional limpet radiation in Lake Baikal

Björn Stelbrink, Alena A. Shirokaya, Catharina Clewing, Tatyana Y. Sitnikova, Larisa A. Prozorova, Christian Albrecht & Tatiana Y. Sitnikova
Lake Baikal is the deepest, oldest and most speciose ancient lake in the world. The lake is characterized by high levels of molluscan species richness and endemicity, including the limpet family Acroloxidae with 25 endemic species. Members of this group generally inhabit the littoral zone, but have been recently found in the abyssal zone at hydrothermal vents and oil-seeps. Here, we use mitochondrial and nuclear data to provide a first molecular phylogeny of the Lake...

Data from: Land-use type and intensity differentially filter traits in above- and belowground arthropod communities

Klaus Birkhofer, Martin M. Gossner, Tim Diekötter, Claudia Drees, Olga Ferlian, Mark Maraun, Stefan Scheu, Wolfgang W. Weisser, Volkmar Wolters, Susanne Wurst, Andrey S. Zaitsev & Henrik G. Smith
1. Along with the global decline of species richness goes a loss of ecological traits. Associated biotic homogenization of animal communities and narrowing of trait diversity threaten ecosystem functioning and human well-being. High management intensity is regarded as an important ecological filter, eliminating species that lack suitable adaptations. Belowground arthropods are assumed to be less sensitive to such effects than aboveground arthropods. 2. Here, we compared the impact of management intensity between (grassland vs. forest)...

Data from: Assessing the effects of human activities on the foraging opportunities of migratory shorebirds in Austral high-latitude bays

Juan G. Navedo, Claudio Verdugo, Ignacio Rodríguez-Jorquera, Jose M. Abad-Gómez, Cristián G. Suazo, Luis E. Castañeda, Valeria Araya, Jorge Ruiz & Jorge S. Gutiérrez
Human presence at intertidal areas could impact coastal biodiversity, including migratory waterbird species and the ecosystem services they provide. Assessing this impact is therefore essential to develop management measures compatible with migratory processes and associated biodiversity. Here, we assess the effects of human presence on the foraging opportunities of Hudsonian godwits (Limosa haemastica, a trans-hemispheric migratory shorebird) during their non-breeding season on Chiloé Island, southern Chile. We compared bird density and time spent foraging in...

Data from: Relative selectivity of plant cardenolides for Na+/K+-ATPases from the monarch butterfly and non-resistant insects

Georg Petschenka, Colleen S. Fei, Juan J. Araya, Susanne Schröder, Barbara N. Timmermann & Anurag A. Agrawal
A major prediction of coevolutionary theory is that plants may target particular herbivores with secondary compounds that are selectively defensive. The highly specialized monarch butterfly (Danaus plexippus) copes well with cardiac glycosides (inhibitors of animal Na+/K+-ATPases) from its milkweed host plants, but selective inhibition of its Na+/K+-ATPase by different compounds has not been previously tested. We applied 17 cardiac glycosides to the D. plexippus-Na+/K+-ATPase and to the more susceptible Na+/K+-ATPases of two non-adapted insects (Euploea...

Distribution and pollination services of wild bees and hoverflies along an altitudinal gradient in mountain hay meadows

Kevin Baumann, Julia Keune, Volkmar Wolters & Frank Jauker
Extensively managed and flower rich mountain hay meadows, hotspots of Europe’s biodiversity, are subject to environmental and climatic gradients linked to altitude. While the shift of pollinators from bee to fly dominated communities with increasing elevation across vegetation zones is well established, the effect of highland altitudinal gradients on the community structure of pollinators within a specific habitat is poorly understood. We assessed wild bee and hoverfly communities, and their pollination service to three plant...

All-trans retinoic acid induces synaptopodin-dependent metaplasticity in mouse dentate granule cells

Maximilian Lenz, Amelie Eichler, Pia Kruse, Julia Muellerleile, Thomas Deller, Peter Jedlicka & Andreas Vlachos
Previously we showed that the vitamin A metabolite all-trans retinoic acid (atRA) induces synaptic plasticity in acute brain slices prepared from the mouse and human neocortex (Lenz et al., 2021). Depending on the brain region studied, distinct effects of atRA on excitatory and inhibitory neurotransmission have been reported. Here, we used intraperitoneal injections of atRA (10 mg/kg) in adult C57BL/6J mice to study the effects of atRA on excitatory and inhibitory neurotransmission in the mouse...

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...

Kristin Ludewig, Yves P. Klinger, Tobias W. Donath, Lukas Bärmann, Carsten Eichberg, Jacob Gadegaad Thomsen, Eugen Görzen, Wiebke Hansen, Eliza M. Hasselquist, Thierry Helminger, Frida Kaiskog, Emma Karlsson, Torsten Kirchner, Carola Knudsen, Nikola Lenzewski, Sigrid Lindmo, Per Milberg, Daniel Pruchniewicz, Elisabeth Richter, Tobias M. Sandner, Judith M. Sarneel, Ralf Schmiede, Simone Schneider, Kathrin Schwarz, Åsa Tjäder … & Rolf Lutz Eckstein
Plant phenology, i. e. the timing of life cycle events, is related to individual fitness and species distribution ranges. Among the environmental factors, phenology is mostly driven by temperature and day length. Rapid adaptation of their phenology may also be important for the success of invasive plant species. Our main aim was to understand how the performance, timing, and temperature dependence of the phenology of the invasive legume Lupinus polyphyllus varies with latitude. L. polyphyllus...

Data from: The past ecology of Abies alba provides new perspectives on future responses of silver fir forests to global warming

Willy Tinner, Daniele Colombaroli, Oliver Heiri, Paul Henne, Marco Steinacher, Johanna Untenecker, Elisa Vescovi, Judy Allen, Gabriele Carraro, Marco Conedera, Fortunat Joos, André Lotter, Jürg Luterbacher, Stephanie Samartin & Verushka Valsecchi
Paleoecology can provide valuable insights into the ecology of species that complement observation and experiment-based assessments of climate-impact dynamics. New paleoecological records (e.g. pollen, macrofossils) from the Italian Peninsula suggest a much wider climatic niche of the important European tree species Abies alba (silver fir) than observed in its present spatial range. To explore this discrepancy between current and past distribution we analyse climatic data (e.g. temperature, precipitation, frost, humidity, sunshine) and vegetation-independent paleoclimatic reconstructions...

Data from: Phylogenetic and comparative genomics of the family Leptotrichiaceae and introduction of a novel fingerprinting MLVA for Streptobacillus moniliformis

Tobias Eisenberg, Ahmad Fawzy, Werner Nicklas, Torsten Semmler & Christa Ewers
Background: The Leptotrichiaceae are a family of fairly unnoticed bacteria containing both microbiota on mucous membranes as well as significant pathogens such as Streptobacillus moniliformis, the causative organism of streptobacillary rat bite fever. Comprehensive genomic studies in members of this family have so far not been carried out. We aimed to analyze 47 genomes from 20 different member species to illuminate phylogenetic aspects, as well as genomic and discriminatory properties. Results: Our data provide a...

Aurélien Miralles, Teddy Bruy, Katherine Wolcott, Mark Scherz, Dominik Begerow, Bank Beszteri, Michael Bonkowski, Janine Felden, Birgit Gemeinholzer, Frank Glaw, Frank Oliver Glöckner, Oliver Hawlitschek, Ivaylo Kostadinov, Tim Nattkemper, Christian Printzen, Jasmin Renz, Nataliya Rybalka, Marc Stadler, Tanja Weibulat, Thomas Wilke, Susanne Renner & Miguel Vences
Natural history collections are leading successful large-scale projects of specimen digitization (images, metadata, DNA barcodes), transforming taxonomy into a big data science. Yet, little effort has been directed towards safeguarding and subsequently mobilizing the considerable amount of original data generated during the process of naming 15–20,000 species every year. From the perspective of alpha-taxonomists, we provide a review of the properties and diversity of taxonomic data, assess their volume and use, and establish criteria for...

Data from: Suitability of traits related to aggression and handleability for integration into pig breeding programmes: genetic parameters and comparison between Gaussian and binary trait specifications

Uta König Von Borstel, Björn Tönepöhl, Anne Appel, Barbara Voß, Horst Brandt, Saied Naderi & Matthias Gauly
Changes in husbandry systems as well as consumers' increasing demands for animal welfare lead to increasing importance of traits such as handleability and aggressiveness in pigs. However, before using such novel traits for selection decisions, information on genetic parameters for these traits for the specific population is required. Therefore, weight gain and behaviour-related traits were recorded in 1004 pigs (814 Pietrain x German Landrace crossbred, 190 German Landrace purebred) at different ages. Behaviour indicators and...

Data from: Sympatric population divergence within a highly pelagic seabird species complex (Hydrobates spp.)

Rebecca S. Taylor, Anna Bailie, Previn Gulavita, Tim Birt, Tomas Aarvak, Tycho Anker-Nilssen, Daniel C. Barton, Kirsten Lindquist, Yuliana Bedolla-Guzmán, Petra Quillfeldt & Vicki L. Friesen
Both physical and non-physical barriers can restrict gene flow among seabird populations. Understanding the relative importance of non-physical barriers, such as breeding phenology, is key to understanding seabird biodiversity. We investigated drivers of diversification in the Leach’s storm-petrel species complex (Hydrobates spp.) by examining population genetic structure across its range. Variation in the mitochondrial control region and six microsatellite loci was assayed in birds sampled from breeding colonies throughout the North Atlantic and North Pacific...

Data from: Reprograming of epigenetic mechanisms controlling host insect immunity and development in response to egg-laying by a parasitoid wasp

Rabia Özbek, Krishnendu Mukherjee, Fevzi Uçkan & Andreas Vilcinskas
Parasitoids are insects that use other insects as hosts. They sabotage host cellular and humoral defenses to promote the survival of their offspring by injecting viruses and venoms along with their eggs. Many pathogens and parasites disrupt host epigenetic mechanisms to overcome immune system defenses, and we hypothesized that parasitoids may utilize the same strategy. We used the ichneumon wasp Pimpla turionellae as a model idiobiont parasitoid to test this hypothesis, with pupae of the...

Data from: Four myriapod relatives – but who are sisters? No end to debates on relationships among the four major myriapod subgroups

Nikolaus U. Szucsich, Daniela Bartel, Alexander Blanke, Alexander Böhm, Alexander Donath, Makiko Fukui, Simon Grove, Shanlin Liu, Oliver Macek, Ryuichiro Machida, Bernhard Misof, Yasutaka Nakagaki, Lars Podsiadlowski, Kaoru Sekiya, Shigekazu Tomizuka, Björn M. Von Reumont, Robert M. Waterhouse, Manfred Walzl, Guanliang Meng, Xin Zhou, Günther Pass & Karen Meusemann
Background: Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to morphological evidence but is in conflict with most previously published phylogenetic trees based on diverse molecular data. Outgroup choice and long-branch attraction effects were stated as possible explanations for these incongruencies. In this study, we addressed these issues by extending the myriapod and outgroup taxon sampling...

Site impacts nutrient translocation efficiency in intra- and interspecies miscanthus hybrids on marginal lands

Elena Magenau, John Clifton-Brown, Danny Awty-Carroll, Chris Ashman, Andrea Ferrarini, Mislav Kontek, Enrico Martani, Kevin Roderick, Stefano Amaducci, Chris Davey, Vanja Jurišić, Jason Kam, Luisa Trindade, Iris Lewandowski & Andreas Kiesel
Miscanthus, a C4 perennial rhizomatous grass, is capable of growing in varied climates and soil types in Europe, including on marginal lands. It can produce high yields with low nutrient inputs when harvested after complete senescence. Senescence induction and rate depend on complex genetic, environmental, and management interactions. To explore these interactions, we analysed four miscanthus hybrids (two novel seed-based hybrids, GRC 3 (M. sinensis × sinensis) and GRC 14 (M. sacchariflorus × sinensis); GRC...

The effect of microprocessor controlled exo-prosthetic knees on limited community ambulators: systematic review and meta-analysis

Andreas Hahn, Simon Bueschges, Melanie Prager & Andreas Kannenberg
The clinical benefits of microprocessor-controlled prosthetic knees (MPKs) in community ambulators have been well-established. A systematic review in limited community ambulators published in 2014 found benefits in safety, performance-based, and patient-reported outcomes. This work updates the previous analysis to the current state of the published evidence. Systematic review and meta-analysis of the effect of MPKs in limited community ambulators. Thirteen research projects presented in 15 publications were identified. Overall validity was “high” in nine studies,...

Data from: The biogeography of Sulawesi revisited: is there evidence for a vicariant origin of taxa on Wallace’s “anomalous island”?

Björn Stelbrink, Christian Albrecht, Robert Hall & Thomas Von Rintelen
Sulawesi, the largest island in the Indonesian biodiversity hotspot region Wallacea, hosts a diverse endemic fauna whose origin has been debated for more than 150 years. We use a comparative approach based on dated phylogenies and geological constraints to test the role of vicariance versus dispersal in the origin of Sulawesi taxa. Most divergence time estimates for the split of Sulawesi lineages from their sister groups postdate relevant tectonic vicariant events, suggesting that the island...

Data from: Inferior cerebellar hypoplasia resembling a Dandy-Walker-like malformation in purebred Eurasier dogs with familial non-progressive ataxia: a retrospective and prospective clinical cohort study

Filipa Bernardino, Kai Rentmeister, Martin J. Schmidt, Andreas Bruehschwein, Kaspar Matiasek, Lara A. Matiasek, Alexander Lauda, Heinz A. Schoon & Andrea Fischer
Cerebellar malformations can be inherited or caused by insults during cerebellar development. To date, only sporadic cases of cerebellar malformations have been reported in dogs, and the genetic background has remained obscure. Therefore, this study`s objective was to describe the clinical characteristics, imaging features and pedigree data of a familial cerebellar hypoplasia in purebred Eurasier dogs. A uniform cerebellar malformation characterized by consistent absence of the caudal portions of the cerebellar vermis and, to a...

Data from: Genomic evidence of demographic fluctuations and lack of genetic structure across flyways in a long distance migrant, the European turtle dove

Luciano Calderón, Leonardo Campagna, Thomas Wilke, Hervé Lormee, Cyril Eraud, Jenny C. Dunn, Gregorio Rocha, Pavel Zehtindjiev, Dimitrios E. Bakaloudis, Benjamin Metzger, Jacopo G. Cecere, Melanie Marx & Petra Quillfeldt
Background: Understanding how past climatic oscillations have affected organismic evolution will help predict the impact that current climate change has on living organisms. The European turtle dove, Streptopelia turtur, is a warm-temperature adapted species and a long distance migrant that uses multiple flyways to move between Europe and Africa. Despite being abundant, it is categorized as vulnerable because of a long-term demographic decline. We studied the demographic history and population genetic structure of the European...

Data from: Burying beetles regulate the microbiome of carcasses and use it to transmit a core microbiota to their offspring

Shantanu P. Shukla, Heiko Vogel, David G. Heckel, Andreas Vilcinskas & Martin Kaltenpoth
Necrophagous beetles utilize carrion, a highly nutritious resource that is susceptible to intense microbial competition, by treating it with antimicrobial anal and oral secretions. However, how this regulates the carcass microbiota remains unclear. Here, we show that carcasses prepared by the burying beetle Nicrophorus vespilloides undergo significant changes in their microbial communities subsequent to their burial and ‘preparation’. Prepared carcasses hosted a microbial community that was more similar to that of beetles’ anal and oral...

Data from: Diatoms do radiate: evidence for a freshwater species flock

Björn Stelbrink, Elena Jovanovska, Zlatko Levkov, Nadja Ognjanova-Rumenova, Thomas Wilke & Christian Albrecht
Due to the ubiquity and high dispersal capacity of unicellular eukaryotes, their often extraordinary diversity found in isolated and long-lived ecosystems such as ancient lakes is typically attributed to multiple colonization events rather than to in situ speciation. However, respective evolutionary studies are very scarce and the often high number of species flocks in ancient lakes across multicellular taxa raises the question whether unicellular species, such as diatoms, may radiate as well. Here, we use...

Data from: Archaeopedological analysis of colluvial deposits in favourable and unfavourable areas: reconstruction of land use dynamics in SW Germany

Jessica Henkner, Jan Ahlrichs, Sean Downey, Markus Fuchs, Bruce James, Andrea Junge, Thomas Knopf, Thomas Scholten & Peter Kühn
Colluvial deposits, as the correlate sediments of human induced soil erosion, depict an excellent archive of land use and landscape history as representatives of human-environment interactions. This study establishes a chronostratigraphy of colluvial deposits and reconstructs past land use dynamics in the Swabian Jura, the Baar and the Black Forest in SW Germany. In the agriculturally favourable Baar area multiple main phases of colluvial deposition, and thus intensified land use, can be identified from the...
