Rationale and objectives Negative self-referential emotions such as embarrassment and shame play a key role in the psychopathology of psychiatric disorders but are often insufficiently addressed by standard treatments. Psychedelics such as ayahuasca – an Amazonian plant decoction containing the psychedelic N,N-dimethyltryptamine (DMT) and harmala alkaloids, have been proposed to positively modulate self-referential processing....
Per- and polyfluoroalkyl substances (PFAS) are a focus of biomonitoring studies globally. In Australia, population PFAS serum concentrations have been determined since 2002 using pooled de-identified serum samples ( n = 4800) collected from the population bi-annually, as a component of the Australian Human Biomonitoring (HBM) project. Locations of environmental PFAS contamination (‘PFAS hotspots’) are known to exist in Austral...
Recent studies have highlighted salt marshes as hotspots for alkalinity generation and export to coastal waters. Several studies emphasize the critical role of anaerobic microbial metabolism as a major source of total alkalinity (TA) generation in marsh soils. However, the contribution of mineral dissolution to salt marsh TA generation has yet to be extensively studied from a mechanistic viewpoint. Therefore, we conducted a la...
Salt marshes provide vital ecosystem services, including coastal protection and carbon sequestration. Roots play a key role in delivering these ecosystem services, as they stabilize soils and contribute to organic carbon accumulation. This study examines the impact of an experimental 3°C temperature increase in a temperate salt marsh on belowground biomass dynamics across three elevation zones (pioneer zone, low marsh, and hig...
Root-Driven Soil Reduction in Wadden Sea Salt MarshesNARA Subscribed
The soil redox potential in wetlands such as peatlands or salt marshes exerts a strong control over microbial decomposition processes and consequently soil carbon cycling. Wetland plants can influence redox by supplying both terminal electron acceptors (i.e. oxygen) and electron donors (i.e. organic matter) to the soil system. However, quantitative insight into the importance of plant effects on wetland soil redox and associat...
Purpose To identify pathogenic microorganisms and microbiological risk factors causing high morbidity and mortality in immunocompromised patients requiring invasive mechanical ventilation due to pneumonia. Methods A retrospective single-center study was performed at the intensive care unit (ICU) of the Department of Internal Medicine at Heidelberg University Hospital (Germany) including 246 consecutive patients with hematologi...
Methane (CH 4 ) is a potent greenhouse gas (GHG) with atmospheric concentrations that have nearly tripled since pre‐industrial times. Wetlands account for a large share of global CH 4 emissions, yet the magnitude and factors controlling CH 4 fluxes in tidal wetlands remain uncertain. We synthesized CH 4 flux data from 100 chamber and 9 eddy covariance (EC) sites across tidal marshes in the conterminous United States to assess...
Reading tea leaves worldwide: Decoupled drivers of initial litter decomposition mass‐loss rate and stabilizationNARA Subscribed
The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding of global decomposition patterns and the drivers of such patterns are hampered by the lack of coherent large‐scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide and found an overall negative correlation between initial mass‐loss rates and stabilization factors of plant‐derived carbon, using the Tea...
