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...

Ni chingadas, ni vendidas, ni traidoras – Las (nuevas) Malinches chicanas

Silja Helber
pp. 33-52. This article will analyze the continued presence of the historical figure of the Malinche, commonly known as the traitor of the Mexican nation at the time of the Conquest. Starting from her origin and biography, its reception in Mexican and Chicano literature of the twentieth century will be studied. Special attention will be paid to her influence in the creation of an identity of the «daughters of the Malinche», that is, of the...

Guadalupe-Tonantzin: una santa transcultural

Stephanie Schütze
pp. 166-178 Parting from an event at the Sanctuary of Our Lady of Guadalupe/ Our Lady of Guadalupe Shrine in Des Plaines Illinois, near Chicago, this article shows how this sacred space acquired cross-cultural political significance for the struggle of Mexican migrants in the United States. It explores the connection between the religious symbol of the Virgin of Guadalupe and the political activism of Mexican migrants. Its political significance is a historically rooted notion that...

Öffentliche Güter im Recht der Europäischen Union

Christian Calliess
Die Europäische Union (EU) verspricht ihren Bürger:innen viel, ist aber von ihren Zuständigkeiten her oftmals nicht in der Lage zu „liefern“. Die EU sichert einen stabilen Euroraum (Art. 119 Abs. 2 AEUV) zu, kann diesen aber – wie die Erschütterungen im Zuge der weltweiten Finanzkrise im Jahre 2008 und die hiermit in Zusammenhang stehende Staatsschuldenkrise gezeigt haben – mangels wirtschafts- und fiskalpolitischer Kompetenzen nicht gewährleisten. Die EU verspricht den Bürger:innen Freizügigkeit ohne Grenzkontrollen in einem...

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...

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...

Stabian Baths in Pompeii. New Research on the Archaic Defenses of the City

Mark Robinson, Monika Trümper, Clemens Brünenberg, Jens-Arne Dickmann, Domenico Esposito, Antonio F. Ferrandes, Giacomo Pardini, Alessandra Pegurri & Christoph Rummel
The plan of the Archaic city of Pompeii and the existence of a distinct walled Altstadt have been much debated in scholarship. The area of the Stabian Baths plays a key role in this debate. Based on a series of excavations in the palaestra of the baths, Heinrich Sulze (1940) and particularly Hans Eschebach (1970s) reconstructed a defensive wall and parallel ditch in this area. Eschebach also identified an Archaic street and city gate in...

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...

Institutioneller Kinderschutz in Krippe und Kita als Gelingensfaktor für Partizipation im pädagogischen Alltag

Dennis Epping & Jasmin Luthardt
Der Artikel thematisiert die Notwendigkeit eines institutionell verankerten Schutzkonzepts zur Wahrung und Umsetzung der Kinderrechte in Krippen und Kitas. Dies kann nur gelingen, wenn a) die pädagogischen Fachkräfte ihre pädagogischen Handlungen hinsichtlich Übergriffigkeit, Macht und Missbrauch reflektieren und b) die Partizipation der Kinder entsprechend der international und national geltenden Gesetze im Alltag umgesetzt wird. Im Anschluss stellen wir ein Modell des institutionellen Kinderschutzes für Krippen und Kitas (IKS) vor, welches der pädagogischen Praxis dahingehend Orientierung...

Myth of Equality? Professional Life of Spanish Republican Women in Exile in Mexico

Marion Röwekamp
pp. 86-108. While the research on the Spanish Republican exile in Mexico has mainly concentrated on the ‘intellectual male exile’ this article will focus on the female Republican exile. It attempts to analyze whether the promises of gender equality that were granted in the constitution of the Second Republic prevailed in exile, whether the Republicans transferred all democratic ideals equally to their exile or whether some achievements were less important to uphold in the Spanish...

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.

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...

Zum Aufstieg des autoritären Populismus. Michael Zürn im Gespräch mit Bernhard Zangl

Michael Zürn
Autoritär-populistische Parteien haben in fast allen liberalen Demokratien in Westeuropa ein Wählerpotential von ca. 20 Prozent der Stimmen. Viel wichtiger noch: Ein erheblicher Anteil der Weltbevölkerung wird von autoritären Populisten regiert. Die bekanntesten Namen sind Bolsonaro, Modi, Erdogan, Orban, Kaczyński, Maduro, Putin und bis vor Kurzem allen voran Trump. Das sind fast alles große Länder, was den autoritären Populismus so wirkmächtig für die internationale Ordnung macht. Der autoritäre Populismus hat sich in relativ kurzer Zeit...

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...

Multidimensional Measurement of Mobile Media Use

Roland Toth
Just like all types of media use, mobile media use is usually measured using retrospective, self-reported indications of quantity in the form of duration and frequency. This is not only problematic due to the fact that people misjudge their own use to a great extent, but also because theoretical approaches predominantly suggest that mere contact is not sufficient for the description of media use. This especially holds for mobile media use, as specific contact episodes...

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...
