    Beschreibung: Metal pollution poses a major threat to aquatic systems especially in anthropogenic influenced areas, in as much as metals are persistent in the environment. The freshwater snail Theodoxus fluviatilis has often been used as an indicator species for the ecological status in river monitoring. In the River Rhine, the native Northern-European form of T. fluviatilis is nowadays extinct, whilst the Danubian form is spreading along the river. The aim of our study was to investigate if the cryptic invader is affected by metal exposure present in the River Rhine and to discuss its potential as an indicator for metal pollution. Several environmental abiotic (14 water environmental variables plus five common metal concentrations in water and biofilm) and biotic parameters (biofilm mass) were measured across 23 sites along the River Rhine. Five population and six histopathological parameters were evaluated on snails collected at all 23 sites. Aqueous chromium concentration was positively correlated to the damage of male reproductive organs of T. fluviatilis, and higher ammonium concentration was correlated to a decrease in snail size and an increase in the proportion of juveniles. None of the analysed snail parameters was negatively correlated to concentrations of other metals measured, like copper and zinc. Therefore, based on the parameters evaluated, our results indicate that the Danubian form of T. fluviatilis is only restrictedly suitable as an indicator for metal pollution in the River Rhine system. Further field and laboratory investigations including other stressors are necessary to evaluate the indicator potential of the cryptic invader holistically.

    Beschreibung: Das Verhältnis von Religion und Politik ist in den vergangenen Jahren verstärkt in den Fokus der Forschung gerückt. Die Autoren dieses Bandes widmen sich diesem Verhältnis unter einer besonderen Zuspitzung. Ihre Beiträge analysieren, inwiefern es zum Selbstverständnis von Religionen gehört, einen Beitrag zur Gestaltung der gesellschaftlichen und politischen Wirklichkeit leisten zu sollen. Mit dieser Problematik verknüpft ist eine zentrale Frage: Wie erklärt und wie äußert sich der Anspruch von Religionen, eine »politische Aufgabe« zu besitzen? Im Fokus stehen die drei großen monotheistischen Religionen Judentum, Christentum und Islam, wobei für das Christentum zusätzlich die konfessionellen Differenzen in den Blick kommen, die zu ganz unterschiedlichen Einschätzungen der politischen Aufgabe des Christentums geführt haben.Für alle drei monotheistischen Religionen nehmen die Beiträger jeweils eine Doppelperspektive ein: historische Beispiele erhellen die jeweiligen Bedingungen und Kontexte für religiös motivierte Teilhabe an politischer Gestaltung und Verantwortung; Systematische Entfaltungen versuchen eine Einbettung dieser Beispiele in die spezifischen Denkhorizonte der jeweiligen Religionen. Das so erhobene politische Selbstverständnis der Religionen wird schließlich mit der Fremdwahrnehmung dieses Selbstverständnisses aus nichtreligiöser Perspektive kontrastiert.

    Beschreibung: MOSES (Modular Observation Solutions for Earth Systems) is a novel observation system that is specifically designed to unravel the impact of distinct, dynamic events on the long-term development of environmental systems. Hydro-meteorological extremes such as the recent European droughts or the floods of 2013 caused severe and lasting environmental damage. Modelling studies suggest that abrupt permafrost thaw events accelerate Arctic greenhouse gas emissions. Short-lived ocean eddies seem to comprise a significant share of the marine carbon uptake or release. Although there is increasing evidence that such dynamic events bear the potential for major environmental impacts, our knowledge on the processes they trigger is still very limited. MOSES aims at capturing such events, from their formation to their end, with high spatial and temporal resolution. As such, the observation system extends and complements existing national and international observation networks, which are mostly designed for long-term monitoring. Several German Helmholtz Association centers have developed this research facility as a mobile and modular “system of systems” to record energy, water, greenhouse gas and nutrient cycles on the land surface, in coastal regions, in the ocean, in polar regions, and in the atmosphere – but especially the interactions between the Earth compartments. During the implementation period (2017-2021), the measuring systems were put into operation and test campaigns were performed to establish event-driven campaign routines. With MOSES’ regular operation starting in 2022, the observation system will then be ready for cross-compartment and cross-discipline research on the environmental impacts of dynamic events.
