Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences

Anthony Vaudo, David Biddinger, Wiebke Sickel, Alexander Keller & Margarita M Lopez-Uribe
Studying the pollen preferences of introduced bees allows us to investigate how species utilize host-plants when establishing in new environments. Osmia cornifrons is a solitary bee introduced into North America from East-Asia for pollination of crops in the Rosaceae. We investigated whether O. cornifrons 1) more frequently collected pollen from host-plant species they coevolved with from their geographic origin, or 2) prefer hosts-plant species of specific plant taxa independent of origin. To address this question,...

Tasan, Nicolas Singewald, Hans-Christian Pape, Christoph M. Flath & Robert Blum
Bioimage analysis of fluorescent labels is widely used in the life sciences. Recent advances in deep learning (DL) allow automating time-consuming manual image analysis processes based on annotated training data. However, manual annotation of fluorescent features with a low signal-to-noise ratio is somewhat subjective. Training DL models on subjective annotations may be instable or yield biased models. In turn, these models may be unable to reliably detect biological effects. An analysis pipeline integrating data annotation,...

Are native and non-native pollinator friendly plants equally valuable for native wild bee communities?

Nicola Seitz, Dennis VanEngelsdorp & Sara D. Leonhardt
Bees rely on floral pollen and nectar for food. Therefore, pollinator friendly plantings are often used to enrich habitats in bee conservation efforts. As part of these plantings, non-native plants may provide valuable floral resources, but their effects on native bee communities have not been assessed in direct comparison with native pollinator friendly plantings. In this study, we performed a common garden experiment by seeding mixes of 20 native and 20 non-native pollinator friendly plant...

Data from: Flower fields and pesticide use interactively shape pollen beetle infestation and parasitism in oilseed rape fields.

Elena Krimmer, Emily Martin, Andrea Holzschuh, Jochen Krauss & Ingolf Steffan-Dewenter
MANUSCRIPT STILL UNDER REVISION Pollen beetles (Brassicogethes spp.) are the main pest of oilseed rape (OSR, Brassica napus) in Europe and responsible for massive yield losses. Upcoming pesticide resistances highlight the need for other means of crop protection, such as natural pest control. Sown flower fields aim to counteract the decrease of insect biodiversity in agricultural landscapes by providing breeding and foraging sites to ecosystem service providers such as parasitoids. However, the optimal age and...

Analysis of RNA-seq, DNA target enrichment, and Sanger nucleotide sequence data resolves deep splits in the phylogeny of cuckoo wasps (Hymenoptera: Chrysididae)

Thomas Pauli, Karen Meusemann, Sandra Kukowka, Manuela Sann, Alexander Donath, Christoph Mayer, Jan Philip Oeyen, Yolanda Ballesteros, Alexander Berg, Eric Van Den Berghe, Hermes Escalona, Adalgisa Guglielmino, Manfred Niehuis, Massimo Olmi, Lars Podsiadlowski, Carlo Polidori, Jeroen De Rond, Paolo Rosa, Thomas Schmitt, Franco Strumia, Mareike Wurdack, Shanlin Liu, Xin Zhou, Bernhard Misof, Ralph Peters … & Oliver Niehuis
The wasp family Chrysididae (cuckoo wasps, gold wasps) comprises exclusively parasitoid and kleptoparasitic species, many of which feature a stunning iridescent coloration and phenotypic adaptations to their parasitic life style. Previous attempts to infer phylogenetic relationships among the family’s major lineages (subfamilies, tribes, genera) based on Sanger sequence data were insufficient to statistically resolve the monophyly and the phylogenetic position of the subfamily Amiseginae and the phylogenetic relationships among the tribes Allocoeliini, Chrysidini, Elampini, and...

New insights into tree architecture from mobile laser scanning and geometry analysis

Dominik Seidel, Yonten Dorji, Bernhard Schuldt, Emilie Isasa & Klaus Körber
The structure and dynamics of a forest are defined by the architecture and growth patterns of its individual trees. In turn, tree architecture and growth result from the interplay between the genetic building plans and environmental factors. We set out to investigate whether (i) latitudinal adaptations of the crown shape occur due to characteristic solar elevation angles at a species’ origin, (ii) architectural differences in trees are related to seed dispersal strategies, and (iii) tree...

Sun compass neurons are tuned to migratory orientation in monarch butterflies

Tu Anh Thi Nguyen, M. Jerome Beetz, Christine Merlin & Basil El Jundi
Every autumn, monarch butterflies migrate from North America to their overwintering sites in Central Mexico. To maintain their southward direction, these butterflies rely on celestial cues as orientation references. The position of the sun combined with additional skylight cues are integrated in the central complex, a region in the butterfly’s brain that acts as an internal compass. However, the central complex does not solely guide the butterflies on their migration but helps monarchs in their...

Sustainable landscape, soil and crop management practices enhance biodiversity and yield in conventional cereal systems

Sarah Redlich, Ingolf Steffan-Dewenter & Emily Martin
1. Input-driven, modern agriculture is commonly associated with large-scale threats to biodiversity, the disruption of ecosystem services and long-term risks to food security and human health. A switch to more sustainable yet highly productive farming practices seems unavoidable. However, an integrative evaluation of targeted management schemes at field and landscape scales is currently lacking. Furthermore, the often-disproportionate influence of soil conditions and agrochemicals on yields may mask the benefits of biodiversity-driven ecosystem services. 2. Here,...

Formicine ants swallow their highly acidic poison for gut microbial selection and control

Simon Tragust, Claudia Herrmann, Jane Häfner, Ronja Braasch, Christina Tilgen, Maria Hoock, Margarita Milidakis, Roy Gross & Heike Feldhaar
Animals continuously encounter microorganisms that are essential for health or cause disease. They are thus challenged to control harmful microbes while allowing acquisition of beneficial microbes. This challenge is likely especially important for social insects with respect to microbes in food, as they often store food and exchange food among colony members. Here we show that formicine ants actively swallow their antimicrobial, highly acidic poison gland secretion. The ensuing acidic environment in the stomach, the...

Data from: Optimizing enrichment of deadwood for biodiversity by varying sun exposure and tree species: an experimental approach

Sebastian Vogel, Martin M. Gossner, Ulrich Mergner, Jörg Müller & Simon Thorn
1. The enrichment of deadwood is essential for the conservation of saproxylic biodiversity in managed forests. However, existing strategies focus on a cost-intensive increase of deadwood amount, while largely neglecting increasing deadwood diversity. 2. Deadwood objects, i.e. logs and branches, from six tree species were experimentally sun-exposed, canopy-shaded, and artificially shaded for four years, after which the alpha-, beta-, and gamma-diversity of saproxylic beetles, wood-inhabiting fungi, and spiders were analyzed. Analyses of beta-diversity included the...

Overexpression of an ALS-associated FUS mutation in C. elegans disrupts NMJ morphology and leads to defective neuromuscular transmission

Sebastian Matthias Markert, Michael Peter Skoruppa, Bin Yu, Ben Mulcahy, Mei Zhen, Shangbang Gao, Michael Sendtner & Christian Stigloher
The amyotrophic lateral sclerosis (ALS) neurodegenerative disorder has been associated with multiple genetic lesions, including mutations in the gene for FUS (Fused in Sarcoma), a nuclear-localized RNA/DNA-binding protein. Neuronal expression of the pathological form of FUS proteins in C. elegans results in mislocalization and aggregation of FUS in the cytoplasm, and leads to impairment of motility. However, the mechanisms by which the mutant FUS disrupts neuronal health and function remain unclear. Here we investigated the...

Data from: A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland

Lorna Cole, David Kleijn, Lynn Dicks, Jane Stout, Simon Potts, Matthias Albrecht, Mario Balzan, Ignasi Bartomeus, Penelope Bebeli, Danilo Bevk, Jacobus Biesmeijer, Róbert Chlebo, Anželika Dautartė, Nikolaos Emmanouil, Chris Hartfield, John Holland, Andrea Holzschuh, Nieke Knoben, Anikó Kovács-Hostyánszki, Yael Mandelik, Heleni Panou, Robert Paxton, Theodora Petanidou, Miguel Pinheiro De Carvalho, … & Jeroen Scheper
1. Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform the post-2020 CAP, we performed a European-scale evaluation to determine how different EFA options vary in...

Data from: DNA metabarcoding for biodiversity monitoring in a national park: screening for invasive and pest species

Laura Hardulak, Jérôme Morinière, Axel Hausmann, Lars Hendrich, Stefan Schmidt, Dieter Doczkal, Jörg Müller, Paul Hebert & Gerhard Haszprunar
DNA metabarcoding was utilized for a large-scale, multi-year assessment of biodiversity in Malaise trap collections from the Bavarian Forest National Park (Germany, Bavaria). Principal Component Analysis of read count-based biodiversities revealed clustering in concordance with whether collection sites were located inside or outside of the National Park. Jaccard distance matrices of the presences of BINs at collection sites in the two survey years (2016 and 2018) were significantly correlated. Overall similar patterns in the presence...

Adaptive evolution of honeybee dance dialects

Patrick Laurenz Kohl
Efficient communication is highly important for the evolutionary success of social animals. Honeybees (genus Apis) are unique in that they communicate the spatial information of resources using a symbolic “language”, the waggle dance. Different honeybee species differ in foraging ecology but it remains unknown whether this shaped variation in the dance. We studied distance dialects – interspecific differences in how waggle duration relates to flight distance – and tested the hypothesis that these evolved to...

Endothelial and leukocyte-derived microvesicles and cardiovascular risk after stroke: PROSCIS-B

Shufan Huo, Nicolle Kränkel, Alexander H. Nave, Pia Sophie Sperber, Jessica Rohmann, Sophie K. Piper, Peter Heuschmann, Ulf Landmesser, Matthias Endres, Bob Siegerink & Thomas G. Liman
Objective: To determine the role of circulating endothelial microvesicles (EMV) and microvesicles (MV) of other origins on long-term cardiovascular outcomes after stroke, we measured them in a cohort of first-ever stroke patients and observed them for three years. Methods: In the PROSpective Cohort with Incident Stroke Berlin (PROSCIS-B), patients with first-ever ischemic stroke were followed for three years. The primary combined endpoint consisted of recurrent stroke, myocardial infarction, and all-cause mortality. Levels of EMV, leukocyte-derived...

Data from: Pest control potential of adjacent agri-environment schemes varies with crop type and is shaped by landscape context and within-field position

Fabian A. Boetzl, Maren Schuele, Krauss Jochen & Steffan-Dewenter Ingolf
Increasing natural pest control in agricultural fields is an important aim of ecological intensification. Combined effects of landscape context and local placement of agri-environmental schemes on natural pest control and within field distance functions of natural pest control agents have rarely been addressed but might affect the distribution of biocontrol providers. Importantly, it is currently unknown whether ecosystem services provided by adjacent agri-environmental schemes (AES) are consistent for different crop types during crop rotation. In...

Diversity and conservation of saproxylic beetles in 42 European tree species: an experimental approach using early successional stages of branches

Sebastian Vogel, Heinz Bussler, Sven Finnberg, Jörg Müller, Elisa Stengel & Simon Thorn
Correction: In the original version of this dataset, the non‐native Prunus serotina was incorrectly interchanged with the native Prunus padus, and eight individuals of saproxylic beetles were incorrectly removed from the data when splitting beetles in saproxylic and non‐saproxylic species. The correct tree species is Prunus serotina, and results refer to a total of 113 species of saproxylic beetles and 30,550 individuals. 1. Tree species diversity is important to maintain saproxylic beetle diversity in managed...
