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...

Atanasije Stojković’s innovative Observation of the Sky

Dragana Grbić
This paper analyses a chapter from the second volume of Fisika [Physics] (Buda, 1802) by Atanasije Stojković, entitled “Šari aerostatičeski” [Aerostatic Balloons], in which the author provided an account of the cutting edge of contemporaneous technology—the hot-air balloon. The description of the construction and use of the hot-air balloon also reveals a line of transition from theodicy to technodicy. Finally, by considering this chapter within the entire context of Stojković’s three-volume scholarly work, the hot-air...

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...

Data from: Reciprocity and the tragedies of maintaining and providing the commons

Simon Gächter, Felix Kölle & Simone Quercia
Social cooperation often requires collectively beneficial but individually costly restraint to maintain a public good, or it needs costly generosity to create one. Status quo effects predict that maintaining a public good is easier than providing a new one. Here, we show experimentally and with simulations that even under identical incentives, low levels of cooperation (the ‘tragedy of the commons’) are systematically more likely in maintenance than provision. Across three series of experiments, we find...

Data from: Phytochrome diversity in green plants and the origin of canonical plant phytochromes

Fay-Wei Li, Michael Melkonian, Carl J. Rothfels, Juan Carlos Villarreal, Dennis W. Stevenson, Sean W. Graham, Gane Ka-Shu Wong, Kathleen M. Pryer & Sarah Mathews
Phytochromes are red/far-red photoreceptors that play essential roles in diverse plant morphogenetic and physiological responses to light. Despite their functional significance, phytochrome diversity and evolution across photosynthetic eukaryotes remain poorly understood. Using newly available transcriptomic and genomic data we show that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants). Phytochromes in charophyte algae are structurally diverse, including canonical and non-canonical forms, whereas in land plants, phytochrome structure is...

Toolbox for: Teaching lab for large cohorts of undergraduates: private and social information in fish

Jost Borcherding, Mike M Webster & Katja Heubel
A challenge in the Bachelor's studies in Biology, is to strive for a balance between reducing the teaching of practical scientific experiments to what is feasible in a short time, and teaching "real" science in undergraduate labs for high numbers of participants. We describe a lab in behavioural biology, with the primary focus on the student learning. However, also the underlying scientific question and the results of the experiment, namely the behaviour of the three-spined...

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...

Phenotype pictures of Arabidopsis thaliana in high light and low light conditions

Benedict Wieters & Juliette De Meaux
The rate at which plants grow is a major functional trait in plant ecology. However, little is known about its evolution in natural populations. Here, we investigate evolutionary and environmental factors shaping variation in the growth rate of Arabidopsis thaliana. We used plant diameter as a proxy to monitor plant growth over time in environments that mimicked latitudinal differences in the intensity of natural light radiation, across a set of 278 genotypes sampled within four...

Data from: Bacterial diversity amplifies nutrient-based plant-soil feedbacks

Simone Weidner, Robert Koller, Ellen Latz, George Kowalchuk, Michael Bonkowski, Stefan Scheu & Alexandre Jousset
Plants foster diverse assemblages of bacteria in the rhizosphere serving important functions which may result in enhanced plant growth. Microbial diversity is increasingly recognized to shape the functionality of microbial communities. This leads to the assumption that there is a positive relationship between rhizosphere diversity and plant growth. Here we investigate how bacterial diversity affects the mineralization of organic matter and plant nutrient acquisition. We hypothesized that altered bacterial diversity will affect nitrogen mineralisation, uptake...

Data from: Peptidomics-based phylogeny and biogeography of Mantophasmatodea (Hexapoda)

Reinhard Predel, Susanne Neupert, Wolf Huetteroth, Jörg Kahnt, Dietmar Waidelich & Steffen Roth
The insect order Mantophasmatodea was described in 2002. Prior to that time, several generations of entomologists had assumed that all major insect taxa were known; thus, its description was a sensation for zoologists. Since then, a surprising abundance and species diversity of this taxon have been found, particularly in the winter rainfall region of South Africa. To learn more about the evolutionary lineages, speciation, and biogeography of Mantophasmatodea, we applied an unusual peptidomics approach. We...

Data from: Evolutionary advantage of small populations on complex fitness landscapes

Kavita Jain, Joachim Krug & Su-Chan Park
Recent experimental and theoretical studies have shown that small asexual populations evolving on complex fitness landscapes may achieve a higher fitness than large ones due to the increased heterogeneity of adaptive trajectories. Here we introduce a class of haploid three-locus fitness landscapes that allow the investigation of this scenario in a precise and quantitative way. Our main result derived analytically shows how the probability of choosing the path of the largest initial fitness increase grows...

Data from: Zinc supplementation inhibits complement activation in age-related macular degeneration

Dzenita Smailhodzic, Freekje Van Asten, Anna M. Blom, Frida C. Mohlin, Anneke I. Den Hollander, Johannes P. H. Van De Ven, Ramon A. C. Van Huet, Joannes M. M. Groenewoud, Yuan Tian, Tos T. J. M. Berendschot, Yara T. E. Lechanteur, Sascha Fauser, Chris De Bruijn, Mohamed R. Daha, Gert Jan Van Der Wilt, Carel B. Hoyng & B. Jeroen Klevering
Age-related macular degeneration (AMD) is the leading cause of blindness in the Western world. AMD is a multifactorial disorder but complement-mediated inflammation at the level of the retina plays a pivotal role. Oral zinc supplementation can reduce the progression of AMD but the precise mechanism of this protective effect is as yet unclear. We investigated whether zinc supplementation directly affects the degree of complement activation in AMD and whether there is a relation between serum...

Data from: Competition is crucial for social comparison processes in long-tailed macaques

Stefanie Keupp, Rowan Titchener, Thomas Bugnyar, Thomas Mussweiler & Julia Fischer
Humans modulate their self-evaluations and behaviour as a function of conspecific presence and performance. In this study we tested for the presence of human-like social comparison effects in long-tailed macaques (Macaca fascicularis). The monkeys’ task was to extract food from an apparatus by pulling drawers within reach and we measured latency between drawer-pulls. Subjects either worked on the task with a partner who could access the apparatus from an adjacent cage, worked in the absence...
