Data from: Honey bees modulate their olfactory learning in the presence of hornet predators and alarm component

Zhengwei Wang, Yufeng Qu, Shihao Dong, Ping Wen, Jianjun Li, Ken Tan & Randolf Menzel
In Southeast Asia the native honey bee species Apis cerana is often attacked by hornets (Vespa velutina), mainly in the period from April to November. During the co-evolution of these two species honey bees have developed several strategies to defend themselves such as learning the odors of hornets and releasing alarm components to inform other mates. However, so far little is known about whether and how honey bees modulate their olfactory learning in the presence...

Data from: Transition from conventional to light-emitting diode street lighting changes activity of urban bats

Daniel Lewanzik & Christian C. Voigt
Light pollution is rapidly increasing and can have deleterious effects on biodiversity, yet light types differ in their effect on wildlife. Among the light types used for street lamps, light-emitting diodes (LEDs) are expected to become globally predominant within the next few years. In a large-scale field experiment, we recorded bat activity at 46 street lights for 12 nights each and investigated how the widespread replacement of conventional illuminants by LEDs affects urban bats: we...

Data from: Biostratigraphy and geometric morphometrics of conchostracans (Crustacea, Branchiopoda) from the Late Triassic fissure deposits of Cromhall Quarry, UK

Jacob D. Morton, David I. Whiteside, Manja Hethke & Michael J. Benton
The enigmatic fissure deposits of south-eastern England and southern Wales are famous for their unique assemblage of Late Triassic vertebrates, although their age is contentious. While recent studies of palynomorphs have dated some as Rhaetian, their conchostracan (Crustacea, Branchiopoda) assemblages have not been described in detail nor used in biostratigraphy. We find that species determination of British Late Triassic conchostracans requires detailed observations of size, shape and ornamentation. We provide evidence that although Euestheria brodieana...

Data from: Interplay between fungicides and parasites: tebuconazole, but not copper, suppresses infection in a Daphnia-Metschnikowia experimental model

Ana Patrícia Cuco, Nelson Abrantes, Fernando Gonçalves, Justyna Wolinska & Bruno B. Castro
Natural populations are commonly exposed to complex stress scenarios, including anthropogenic contamination and their biological enemies (e.g., parasites). The study of the pollutant-parasite interplay is especially important, given the need for adequate regulations to promote improved ecosystem protection. In this study, a host-parasite model system (Daphnia spp. and the microparasitic yeast Metschnikowia bicuspidata) was used to explore the reciprocal effects of contamination by common agrochemical fungicides (copper sulphate and tebuconazole) and parasite challenge. We conducted...

Data from: Analysis of morphological variability in the clam shrimp Eosestheria middendorfii (Crustacea, Spinicaudata) from the Lower Cretaceous of China, and its implications for spinicaudatan taxonomy

Manja Hethke, Franz T. Fürsich, Jacob D. Morton & Baoyu Jiang
Unresolved taxonomic issues regarding spinicaudatans, clam shrimps that formed the most abundant faunal element in the lacustrine Barremian to Aptian Yixian Formation, have hampered palaeoecological and evolutionary interpretations of this key fossil group. Here, we analyse morphological variability in East Asian clam-shrimp taxa by quantifying: (1) size and shape; and (2) ornamental features (radial lirae distances). Intergeneric variability was examined using 51 specimens of various East Asian Mesozoic taxa, 16 of which were chosen for...

Data from: Do microplastic particles affect Daphnia magna at the morphological, life history and molecular level?

Hannes Imhof, Jakub Rusek, Michaela Thiel, Justyna Wolinska, Christian Laforsch & Hannes K. Imhof
Microplastic particles are ubiquitous not only in marine but also in freshwater ecosystems. However, the impacts of microplastics, consisting of a large variety of synthetic polymers, on freshwater organisms remains poorly understood. We examined the effects of two polymer mixtures on the morphology, life history and on the molecular level of the waterflea Daphnia magna (three different clones). Microplastic particles of ~40 µm were supplied at a low concentration (1% of the food particles) leading...

Increased immune marker variance in a population of invasive birds

Hanna Prüter, Mathias Franz, Sönke Twietmeyer, Niklas Böhm, Gudrun Middendorff, Ruben Portas, Jörg Melzheimer, Holger Kolberg, Georg Von Samson‐Himmelstjerna, Alex D. Greenwood, Dörte Lüchow, Kristin Mühldorfer & Gábor Árpád Czirják
Immunity and parasites have been linked to the success of invasive species. Especially lower parasite burden in invasive populations has been suggested to enable a general downregulation of immune investment (Enemy Release and Evolution of Increased Competitive Ability Hypotheses). Simultaneously, keeping high immune competence towards potentially newly acquired parasites in the invasive range is essential to allow population growth. To investigate the variation of immune effectors of invasive species, we compared the mean and variance...

EFFECTS OF MICROPLASTICS AND DROUGHT ON SOIL ECOSYSTEM FUNCTIONS AND MULTIFUNCTIONALITY

Yudi M. Lozano, Carlos A. Aguilar-Trigueros, Gabriela Onandia, Stefanie Maaß, Tingting Zhao & Matthias C. Rillig
Microplastics in soils have become an important threat for terrestrial systems as they may potentially alter the geochemical/biophysical soil environment and can interact with drought. As microplastics may affect soil water content, this could exacerbate the well-known negative effects of drought on ecosystem functionality. Thus, functions including litter decomposition, soil aggregation or those related with nutrient cycling can be altered. Despite this potential interaction, we know relatively little about how microplastics, under different soil water...

Data from: Ecological conditions alter cooperative behaviour and its costs in a chemically defended sawfly

Carita Lindstedt, Antti Miettinen, Dalial Freitak, Tarmo Ketola, Andrés López-Sepulcre, Elina Mäntylä & Hannu Pakkanen
The evolution of cooperation and social behaviour is often studied in isolation from the ecology of organisms. Yet, the selective environment under which individuals evolve is much more complex in nature, consisting of ecological and abiotic interactions in addition to social ones. Here we measured the life-history costs of cooperative chemical defence in a gregarious social herbivore, Diprion pini pine sawfly larvae, and how these costs vary under different ecological conditions. We ran a rearing...

Polymorphisms in dipeptidyl peptidase 4 reduce host cell entry of Middle East respiratory syndrome coronavirus

Hannah Kleine-Weber, Simon Schroeder, Nadine Krüger, Alexander Prokscha, Hassan Y. Naim, Marcel A. Müller, Christian Drosten, Stefan Pöhlmann & Markus Hoffmann
Middle East respiratory syndrome (MERS) coronavirus (MERS-CoV) causes a severe respiratory disease in humans. The MERS-CoV spike (S) glycoprotein mediates viral entry into target cells. For this, MERS-CoV S engages the host cell protein dipeptidyl peptidase 4 (DPP4, CD26) and the interface between MERS-CoV S and DPP4 has been resolved on the atomic level. Here, we asked whether naturally-occurring polymorphisms in DPP4, that alter amino acid residues required for MERS-CoV S binding, influence cellular entry...

Survival of antimicrobial peptide resistant Staphylococcus aureus in mealworm beetles (Tenebrio molitor) with manipulated AMPexpression

Jens Rolff & Baydaa El Shazely
Antimicrobial peptides (AMP) are essential immune effectors of multicellular organisms. Bacteria can evolve resistance to AMPs. Surprisingly, when used to challenge the insect Tenebrio molitor, Staphylococcus aureus resistant to an abundant beetle AMP (tenecin 1) and also pleiotropically to phagocytosis did not increase host mortality or bacterial load compared to infections with wild-type S. aureus. A possible explanation is that antimicrobial resistance is costly due to collaterally increased sensitivity of AMP-resistant strains to other immune...

Data from: Can fractal dimensions objectivize gastropod shell morphometrics? A case study from Lake Lugu (SW China)

Robert Wiese, Kyle Harrington, Kai Hartmann, Manja Hethke, Thomas Von Rintelen, Hucai Zhang, Le-Jia Zhang & Frank Riedel
Morphometrics are fundamental for statistical analyses of fossils, particularly because soft parts or DNA are rarely preserved and thus hard parts such as shells are commonly the only source of information. Geometric morphometrics i.e. landmark analysis has been successfully established but exhibits a couple of shortcomings. On the one hand landmarking is rather subjective and on the other hand the application at the level of micro-sculpture is difficult. With the aid of high-resolution 3D scanning...

Bee diversity in island-like habitats (kettle holes) to assess connectivity in agricultural landscapes - Part 1 of data collection

Sissi Lozada-Gobilard
During June and July of 2017, wild bees were collected using color traps (blue, yellow and white pans) in small water bodies called kettle holes embedded in agricultural landscapes in the north of Germany. After all wild bees were identified to species level, from a subset of samples we measured the Intertegular distance ITD (distance between the wings) as body size and searched for functional traits regarding sociality (solitary, eusocial, parasitic) nesting type (below- or...

Voter Dynamics on Clustered Networks

Jan-Hendrik Niemann
The dynamical behavior of social systems can be described by agent-based models. One famous and important model for the description of voting behavior is the so-called (extended) voter model where agents decide between various options based on different rules. A key factor is the interaction network, that is what information the agents obtain and how they interact with each other. This data set provides simulation data to analyze the influence of the interaction network. A...

Livestock management promotes bush encroachment in savanna systems by altering plant-herbivore feedback

Franziska Koch, Britta Tietjen, Katja Tielbörger & Korinna Allhoff
This repository contains all code to reproduce the analysis in Koch et al. 2022 "Livestock management promotes bush encroachment in savanna systems by altering plant-herbivore feedback". We use a set of coupled differential equations to describe competition between shrubs and grasses, as well as plant biomass consumption via grazing and browsing. Grazers were assumed to receive a certain level of care from farmers, so that grazer densities emerge dynamically from the combined effect of vegetation...

Data from: Savanna resilience to droughts increases with proportion of browsing wild herbivores and plant functional diversity

Katja Irob
1. Maintaining the resilience and functionality of savannas is key to sustaining the ecosystem services they provide. This maintenance is largely dependent on the resilience of savannas to stressors, such as prolonged droughts. The resilience to drought is largely determined by the interaction of herbivores and the functional composition of vegetation. So far, our understanding and ability to predict the response of savannas to drought under different types of rangeland use and as a function...

Impact of new traumatic or stressful life events on pre-existing PTSD in traumatized refugees: results of a longitudinal study

Katrin Schock, Maria Böttche, Rita Rosner, Mechthild Wenk-Ansohn & Christine Knaevelsrud
Background: A significant proportion of trauma survivors experience an additional critical life event in the aftermath. These renewed experiences of traumatic and stressful life events may lead to an increase in trauma-related mental health symptoms. Method: In a longitudinal study, the effects of renewed experiences of a trauma or stressful life event were examined. For this purpose, refugees seeking asylum in Germany were assessed for posttraumatic stress symptoms (PTS), Posttraumatic Stress Diagnostic Scale (PDS), anxiety,...

The resources we provide include the raw sequence reads, the assembled contigs, the putative open reading frames, the contig/ORF annotations and the normalized as well as non-normalized expression levels.

Data from: No evidence that plant-soil feedback effects of native and invasive plant species under greenhouse conditions are reflected in the field

Conrad Schittko, Christian Runge, Marek Strupp, Sascha Wolff & Susanne Wurst
Plant–soil feedback (PSF) may affect above-ground higher trophic levels in glasshouse experiments, but evidence from field studies on the relevance of these multitrophic interactions for plant performance is lacking. Therefore, we examined whether PSF effects of several native and invasive plant species occur also in the field and influence plant damage by above-ground herbivores. Root zone soil from an abandoned urban field was used as inocula for the PSF experiment. First, we grew eight urban...

Data from: Changing the habitat: the evolution of inter-correlated traits to escape from predators

Dirk J. Mikolajewski, Kristin Scharnweber, Bin Jiang, Sebastian Leicht, Ruediger Mauersberger & Frank Johansson
Burst escape speed is an effective and widely used behaviour for evading predators, with burst escape speed relying on several different morphological features. However, we know little about how behavioural and underlying morphological attributes change in concert as a response to changes in selective predation regime. We studied inter-correlated trait differentiation of body shape and burst-swim-mediating morphology in response to a habitat shift related reduction in burst escape speed using larvae of the dragonfly genus...
