Zusammenfassung Der extreme Preisanstieg von Wohnimmobilien in intensiv touristisch geprägten ländlichen Orten verschärft sozioökonomische Disparitäten und stellt politische Entscheidungsträger*innen vor raumplanerische Herausforderungen. Anhand des Fallbeispiels der Alpendestination Garmisch-Partenkirchen zielt der Artikel zunächst darauf ab, ein besseres Verständnis über die Zusammenhänge zwischen Tourismus- und Wohnimmobili...
In lichen symbioses, fungal secondary metabolites provide UV protection on which lichen algae such as trebouxiophycean green algae—the most prominent group of photobionts in lichen symbioses—sensitively depend. These metabolites differ in their UV absorbance capability and solvability, and thus vary in their propensity of being leached from the lichen body in humid and warm environments, with still unknown implications for the...
Clay mineral formation in Permian rocks of a geothermal borehole at Northern Upper Rhine Graben, GermanyNARA Subscribed
Hydrothermally altered rhyolite rocks in the Permian Donnersberg Formation of a geothermal borehole in the Northern Upper Rhine Graben (Germany) were investigated to find out answers for the low hydraulic conductivity of the rocks. The composition of clay minerals and the temperature of smectite–illite transformation were carried out using X-ray diffraction, X-ray fluorescence, transmission electron microscopy, Fourier transfo...
Arginine, homoarginine (hArg), asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA) affect nitric oxide metabolism and altered concentrations are associated with cardiovascular morbidity and mortality. We analyzed these metabolites using liquid chromatography–tandem mass spectrometry in patients with atrial fibrillation (AF) ( n = 241) with a focus on heart rhythm at blood withdrawal, AF progression phenot...
New tricks of an old enemy: isolates of F usarium graminearum produce a type A trichothecene mycotoxinNARA Subscribed
Summary The ubiquitous filamentous fungus F usarium graminearum causes the important disease F usarium head blight on various species of cereals, leading to contamination of grains with mycotoxins. In a survey of F . graminearum ( sensu stricto ) on wheat in N orth A merica several novel strains were isolated, which produced none of the known trichothecene mycotoxins despite causing normal disease symptoms. In rice cultures, a...

Age assignment of a diatomaceous ooze deposited in the western Amundsen Sea Embayment after the Last Glacial MaximumNARA Subscribed
Reliable dating of glaciomarine sediments deposited on the Antarctic shelf since the Last Glacial Maximum (LGM) is challenging because of the rarity of calcareous (micro‐) fossils and the recycling of fossil organic matter. Consequently, radiocarbon ( 14 C) ages of the acid‐insoluble organic fraction (AIO) of the sediments bear uncertainties that are difficult to quantify. Here we present the results of three different methods...
Summary Material flows of the economic cycle can contain toxic substances, which enter the economy as impurities in raw materials or are intentionally added as minor or even main constituents during the manufacture of industrial or consumer goods. Cadmium, predominantly associated with zinc minerals, is a by‐product of the primary zinc production. Cadmium is generated when zinc is extracted from zinc ores and concentrates, an...
