Long-term drought effects on landscape water storage and recovery under contrasting landuses
Process-based, tracer-aided ecohydrological modelling and ML were combined to estimate the effects of long-term drought on water fluxes/storage in the Spree catchment. The recent major droughts resulted in declines in groundwater recharge (>40 %), evapotranspiration (up to 16 %) and soil moisture (up to 6 %). Groundwater levels may not recover in 15 years if precipitation anomalies persist.

Inland recreational fisheries contribute nutritional benefits and economic value but are vulnerable to climate change
The research team estimates that recreational fishing in lakes and rivers accounts for more than 11 per cent of the annually reported catches in inland fisheries worldwide. The analyzed total consumption value of harvested fish is around 10 billion US dollars per year. Due to climate change and direct human impacts on freshwater ecosystems, the productivity of important fish species is declining.
A scenario-guided strategy for the future management of biological invasions
The study used a scenario-based approach to explore management options for invasive species in Europe. During two workshops involving a multidisciplinary team of experts, a management strategy arranged into 19 goals relating to policy, research, public awareness, and biosecurity was developed considering different future scenarios of biological invasions.
Global introductions and environmental impacts of freshwater megafish
The authors investigated the introductions of freshwater megafish on a global scale and assessed their environmental impacts. Of the 134 extant freshwater megafish species, 46% have been introduced to new environments, and of these, 69% have established self-sustaining alien populations and posed negative impacts on native species through nine different mechanisms.
