Data from: What factors increase the vulnerability of native birds to the impacts of alien birds?

Thomas Evans, Jonathan Jeschke, Liu Chunlong, David Redding, Çağan Şekercioğlu & Tim Blackburn
This dataset accompanies a published paper (Evans et al. 2021) which aims to identify the factors that influence the vulnerability of native bird species to the impacts of alien bird species. In this paper we used mixed-effects models to test 14 variables that we hypothesised to influence vulnerability: this is a dataset of the 14 varaibles. We carried out our analyses using ten sets of these 14 variables: we provide all ten sets of these...

Genotypes and their interaction effects on reproduction and mating-induced immune activation in Drosophila melanogaster

Claudia Fricke, Sergio Ávila-Calero & Sophie Armitage
Mating causes considerable alterations in female physiology and behaviour, and immune gene expression, partly due to proteins transferred from males to females during copulation. The magnitude of these phenotypic changes could be driven by the genotypes of males and females, as well as their interaction. To test this, we carried out a series of genotype by genotype (G × G) experiments using Drosophila melanogaster populations from two distant geographical locations. We expected lines to have...

Thermodynamic Analysis of Allosteric and Chelate Cooperativity in Di- and Trivalent Ammonium/Crown-Ether Pseudorotaxanes

Karol Nowosinski, Larissa K. S. von Krbek, Nora L. Traulsen & Christoph A. Schalley
A detailed thermodynamic analysis of the axle-wheel binding in di- and trivalent secondary ammonium/[24]crown-8 pseudorotaxanes is presented. Isothermal titration calorimetry (ITC) data and double mutant cycle analyses reveal an interesting interplay of positive as well as negative allosteric and positive chelate cooperativity thus providing profound insight into the effects governing multivalent binding in these pseudorotaxanes.

Soil conditions drive belowground trait space in temperate agricultural grasslands

Tom Lachaise, Joana Bergmann, Norbert Hölzel, Valentin Klaus, Till Kleinebecker, Matthias Rillig & Mark Van Kleunen
Plant belowground organs perform essential functions, including water and nutrient uptake, anchorage, vegetative reproduction and recruitment of mutualistic soil microbiota. Recently, multivariate analyses showed that root traits of species can largely be linked to a ‘conservation’ and a ‘collaboration’ gradient. Here, we tested whether this species-level bidimensional belowground trait space also exists at the community level in grasslands. Furthermore, we tested whether the position of grassland communities in belowground trait space relates to environmental variables....

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...

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...

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...

First Artificial Receptor for Caffeine—A New Concept for the Complexation of Alkylated Oxopurines

A reversal in sensory processing accompanies ongoing ecological divergence and speciation in Rhagoletis pomonella

Cheyenne Tait, Hinal Kharva, Marco Schubert, Daniel Kritsch, Andy Sombke, Jürgen Rybak, Jeffrey Feder & Shannon Olsson
Changes in behavior often drive rapid adaptive evolution and speciation. However, the mechanistic basis for behavioral shifts is largely unknown. The tephritid fruit fly Rhagoletis pomonella is an example of ecological specialization and speciation in action via a recent host plant shift from hawthorn to apple. These flies primarily utilize specific odors to locate fruit, and because they mate only on or near host fruit, changes in odor preference for apples versus hawthorns translate directly...

Global change shifts trade-offs among ecosystem functions in woodlands restored for multifunctionality

Sebastian Fiedler, José Monteiro, Kristin Hulvey, Rachel Standish, Michael Perring & Britta Tietjen
1. Ecological restoration increasingly aims at improving ecosystem multifunctionality and making landscapes resilient to future threats, especially in biodiversity hotspots such as Mediterranean-type ecosystems. Plants and their traits play a major role in the functioning of an ecosystem. Therefore, successful restoration towards long-term multifunctionality requires a fundamental mechanistic understanding of this link under changing climate. An integrated approach of empirical research and simulation modelling with a focus on plant traits can allow this understanding. 2....

Intravital quantification reveals dynamic calcium concentration changes across B cell differentiation stages

Carolin Ulbricht, Ruth Leben, Asylkhan Rakhymzhan, Frank Kirchhoff, Lars Nitschke, Helena Radbruch, Raluca Niesner & Anja Hauser
Calcium is a universal second messenger present in all eukaryotic cells. The mobilization and storage of Ca2+ ions drives a number of signaling-related processes, stress-responses or metabolic changes, all of which are relevant for the development of immune cells and their adaption to pathogens. Here, we introduce the FRET-reporter mouse YellowCaB expressing the genetically encoded calcium indicator TN-XXL in B lymphocytes. Calcium-induced conformation change of TN-XXL results in FRET-donor quenching measurable by two-photon fluorescence lifetime...

Large-scale drivers of relationships between soil microbial properties and organic carbon across Europe

The aim of this study was to quantify direct and indirect relationships between soil microbial community properties (potential basal respiration, microbial biomass) and abiotic factors (soil, climate) in three major land-cover types. Location: Europe Time period: 2018 Major taxa studied: Microbial community (fungi and bacteria) We collected 881 soil samples from across Europe in the framework of the Land Use/Land Cover Area Frame Survey (LUCAS). We measured potential soil basal respiration at 20ºC and microbial...
