Rock glaciers (RGs) provide significant water resources in mountain areas under climate change. Recent research has highlighted high concentrations of solutes including trace elements in RG-fed waters, with negative implications on water quality. Yet, sparse studies from a few locations hinder conclusions about the main drivers of solute export from RGs.

Through the analysis of input-output budgets of sulphur (S), nitrogen (N), base cations and alkalinity significant trends emerged. Notably, S and N input concentrations significantly declined since the 1980s, by approximately 78 % and 22 %, respectively, with N primarily declining after 2000.

The effects of the COVID-19 lockdown on deposition and surface water chemistry were investigated in an area south of the Alps. Long-term data provided by the monitoring networks revealed that the deposition of sulfur and nitrogen compounds in this area has stabilized since around 2010; in 2020, however, both concentrations and deposition were significantly below the average values of the previous decade for SO and NO. Less evident changes were observed for NH and base cation.

To mitigate the risk of corruption and its harmful effects on those initiatives, health programs often use multiple anti-corruption mechanisms, including codes of conduct, documentation and reporting requirements, and trainings. Unfortunately, the introduction of anti-corruption mechanisms tends to occur without an explicit consideration of how each mechanism will affect health services and health outcomes.

Glial fibrillary acidic protein showed a complementary distribution pattern to perineuronal nets, visualized with Wisteria floribunda agglutinin. With progressing age (12-36 months), a strong increase of lipofuscin and gliosis occurred in functionally characterized cortical areas, whereas a concomitant, area-specific loss of perineuronal nets was found in the cortical somatosensory representation of the hindlimbs.
