A Novel In Situ Experimental Setup for Studying the Impact of Bedform Celerity on 2D Oxygen Distribution in the Hyporheic Zone of Streams
The authors investigated the influence of dynamic hyporheic zones. They developed of a novel field-based setup that enabled the simultaneous monitoring of oxygen dynamics and bedform migration in a stream. Contrary to what has been reported in several studies, they observed more strongly oxygenated bedforms at the highest velocity studied.

Global assessment of alien freshwater megafauna reveals complex socio-economic impacts
This study shows: Over 40 percent of extant large freshwater animals (megafauna) have been deliberately introduced outside their natural ranges, often for economic gain. While these alien species can provide substantial benefits to certain groups in the introduced regions, they also posed profound and often underestimated risks to native biodiversity and local people.
Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments
Enhancing process interpretation with isotopes: potential discharge-isotope trade-offs in ecohydrological modelling of heavily managed lowland catchments
The authors enhanced a tracer-aided hydrological model to help constrain estimates of ecohydrological partitioning and water balance compartments in sub-catchments of the Middle Spree catchment. They disentangled ecohydrological funtioning in this ET dominated region despite the complexity of the heterogeneous landuse, extensive hydraulic infrastructure and long legacy of intensive management.
