Understanding ecohydrology and biodiversity in aquatic nature-based solutions in urban streams and ponds through an integrative multi-tracer approach
The authors used stable water isotopes, hydrochemistry and eDNA in a novel, integrated tracer-approach to show how ecohydrological interactions and biodiversity in urban aquaNBS are influenced by urban water sources and connectivity. The direct linkages between hydrology and microbial patterns are highlighted, illustrating the sensitivity of aquaNBS to anthropogenic and climate influences.

The Unexploited Treasures of Hydrological Observations Beyond Streamflow for Catchment Modeling
Other hydrological data than streamflow have the potential to improve process consistency in hydrological modeling and consequently for predictions under change. The authors review how storage and flux variables are used for model evaluation and calibration; improving process representation.

Biogenic polyphosphate as relevant regulator of seasonal phosphate storage in surface sediments of stratified eutrophic lakes
Using nuclear magnetic resonance spectroscopy, the authors studied the polyphosphate seasonality in the topmost sediment layer of three stratified lakes with prolonged anoxic periods during summer stratification. Polyphosphate acted as a temporary phosphorus storage, formed at the beginning of the summer stratification under oxic conditions and released time delayed under anoxic conditions.

Recent Developments and Emerging Challenges in Tracer-Aided Modeling
The authors reviewed recent advances and remaining challenges of tracer-aided modelling which offers insights into internal storages, water sources, flow pathways, mixing processes, and water ages, which cannot be derived from hydrometric data alone. Tracer data have the capability to falsify hydrological models and test hypotheses, and thus increase understanding of hydrological processes.
