Der Beitrag fasst die Ergebnisse eines von der Deutschen Forschungsgemeinschaft (DFG) im Rahmen des SPP 1630 von 2012 bis 2018 geförderten Projekts zusammen. Während der Feldkampagnen wurden archäologische, baugeschichtliche, geoarchäologische und geophysikalische Untersuchungen durchgeführt. Der Fokus der Untersuchungen lag auf der topographischen und wirtschaftlichen Entwicklung von Ainos in der Antike, insbesondere in der römischen Kaiserzeit, sowie in der byzantinischen Epoche. Neue Erkenntnisse konnten hinsichtlich der Entwicklung der Stadt und der Lokalisierung von möglichen Hafenstandorten erzielt...

Macrobenthic Cumacea collected by epibenthic sledge from the Amundsen Sea in March 2008 and from the Prince Gustav Channel and Duse Bay, Eastern Antarctic Peninsula in March 2018

Katrin Linse, Laura Steib, Angelika Brandt & Davide Di Franco
In 2008 RRS James Clark Ross investigated the marine benthic biodiversity in Amundsen Sea and in 2018 the marine benthic biodiversity of the Prince Gustav Channel (PGC) area and the macrobenthic cumacean fauna (Peracarida, Crustacea) collected by epibenthic sledge (EBS) has been assessed for species richness, abundance and assemblage composition. In total 4431 cumacean specimens assigned to 58 morphospecies and 5 families were identified. To set the cumacean dataset into a wider context, published cumacean...

Octavio Paz entre la literatura mundial y las literaturas del mundo

Gesine Müller
pp. 51-63 The debate around the concept of world literature, held with new intensity in the last twenty years, is part, within the framework of cultural studies, of the controversies that are closely associated with issues related to global networks in a polycentric world. In view of this, this article would first of all like to open the field of tension between the concepts of world literature and literature of the world, with the purpose...

Transposable elements (TEs) are selfish genomic parasites whose ability to spread autonomously is facilitated by sexual reproduction in their hosts. If hosts become obligately asexual, TE frequencies and dynamics are predicted to change dramatically, but the long-term outcome is unclear. Here, we test current theory using whole-genome sequence data from eight species of bdelloid rotifers, a class of invertebrates in which males are thus far unknown. Contrary to expectations, we find a variety of active...

Supplemental Data to: Mediterranean Diet, Alzheimer Disease Biomarkers, and Brain Atrophy in Old Age

Heneka, Daniel Janowitz, Ingo Kilimann, Christoph Laske, Franziska Maier, Coraline Danielle Metzger, Matthias H. Munk … & Michael Wagner
Objective: To determine whether following a Mediterranean-like diet (MeDi) relates to cognitive functions and in vivo biomarkers for Alzheimer disease (AD), we analyzed cross-sectional data from the German DZNE-Longitudinal Cognitive Impairment and Dementia Study. Method: The sample (n = 512, mean age 69.5 ± 5.9 years) included 169 cognitively normal participants and individuals at higher AD risk (53 with relatives with AD, 209 with subjective cognitive decline, and 81 with mild cognitive impairment). We defined...

Repositories for taxonomic data: Where we are and what is missing

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...

Uncovering key metabolic determinants of the drug interactions between trimethoprim and erythromycin in Escherichia coli

Qin Qi, S Andreas Angermayr & Tobias Bollenbach
Understanding interactions between antibiotics used in combination is an important theme in microbiology. Using the interactions between the antifolate drug trimethoprim and the ribosome-targeting antibiotic erythromycin in Escherichia coli as a model, we applied a transcriptomic approach for dissecting interactions between two antibiotics with different modes of action. When trimethoprim and erythromycin were combined, the transcriptional response of genes from the sulfate reduction pathway deviated from the dominant effect of trimethoprim on the transcriptome. We...

»[E]in Vater, dächte ich, ist doch immer ein Vater«. Figurentypen und ihre Operationalisierung

Benjamin Krautter, Janis Pagel, Nils Reiter & Marcus Willand
Dieser Artikel behandelt die Operationalisierung von Figurentypen im deutschsprachigen Drama. Ausgehend von der dramen- und theatergeschichtlichen Forschung werden Figuren bestimmt, die einem der drei Figurentypen ›Intrigant*in‹, ›tugendhafte Tochter‹ und ›zärtlicher Vater‹ entsprechen. Für die Figuren wurden eigenschaftsbasierte Datensätze erstellt, die zu ihrer automatischen Klassifikation herangezogen werden. Neben die inhaltliche Komplexität von Figuren und die theoretische Bestimmung von Figurentypen tritt die methodische Herausforderung, ausgehend von einer kleinen Menge an Annotationen zu generalisieren. Unsere Experimente zeigen, dass...

The Caucasian dwarf goby, a new alien Gobiidae spreading at the Lower Rhine, Germany

Jost Borcherding, Dominik Aschemeier, Jacqueline Bruhy, Lisa Heermann, Jan Lindner, Sophia Lara Schröder, Katalin Wagner & Stefan Staas
With the first catch of the Caucasian dwarf goby Knipowitschia cf. caucasica at the Lower Rhine, we now describe the distribution in this area, add first data on the population structure and feeding in the new habitat and draw attention to this new member of the fish community in western European countries.

Data from: Ovipositor and mouthparts in a fossil insect support a novel ecological role for early orthopterans in 300 million years old forests

Lu Chen, Alexander Blanke, Jun-Jie Gu, Qiang Yang, Dong Ren & Olivier Béthoux
A high portion of the earliest known, Pennsylvanian, insect fauna is composed of the so-called ‘lobeattid insects’, which systematic affinities and role as foliage feeders remain debated. We investigated hundreds of samples of a new lobeattid species from the Xiaheyan locality using a combination of photographic techniques, including Reflectance Transforming Imaging, and geometric morphometrics, to document its morphology, and infer its phylogenetic position and ecological role. Ctenoptilus frequens sp. nov. possessed a sword-shaped ovipositor whose...

Phenotypic convergence in a natural Daphnia population acclimated to low temperature

Christian Werner, Kathrin A. Otte & Eric Von Elert
Fluidity of a given membrane decreases at lower ambient temperatures, whereas it rises at increasing temperatures, which is achieved through changes in membrane lipid composition. In consistence with homeoviscous adaptation theory, lower temperatures result in increased tissue concentrations of polyunsaturated fatty acids (PUFAs) in D. magna, suggesting a higher PUFA requirement at lower temperatures. However, so far homeoviscous adaptation has been suggested for single or geographically separated Daphnia genotypes only. Here we investigated changes in...
