Multiple stressors affecting microbial decomposer and litter decomposition in restored urban streams: Assessing effects of salinization, increased temperature, and reduced flow velocity in a field mesocosm experiment
Seasonality, rather than estuarine gradient or particle suspension/sinking dynamics, determines estuarine carbon distributions
Tapping into fungal potential: Biodegradation of plastic and rubber by potent Fungi
The presence of plastics in our environment is an increasing burden on nature and our health. The authors have now identified fungi isolated from freshwater ecosystems that can efficiently degrade plastic polymers made of polyurethane, polyethylene and tyre rubber. Contrary to previous assumptions, no pre-treatment of the plastics was necessary.
Evidence for a by-product mutualism in a group hunter depends on prey movement state
Researchers from the Cluster of Excellence Science of Intelligence (SCIoI), in which the Humboldt-Universität zu Berlin (HU Berlin) and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) are involved, have proven in an underwater field study in the ocean off Mexico: the faster a school of prey moves, the higher the capture rate of the striped marlin.

Climate variability in a 3.8 Ma old sedimentary record from the hyperarid Atacama Desert

Ecohydrological resilience and the landscape water storage continuum in droughts
A better understanding of water storage dynamics at medium scales, i.e. areas between 10 and 100 square kilometres, could help to better predict and ensure the availability of water resources, even in times of climate change. To this end, the researchers here synthesised findings from several long-term studies and introduced the concept of ecohydrological resilience.
A global systematic map of knowledge of inland commercial navigation effects on freshwater ecosystems
The authors conducted a systematic mapping of the published literature (1908–2021) to provide a global synthesis of the effects of inland navigation on the biotic and abiotic components of freshwater ecosystems. Inland navigation impacts rivers through shipping, infrastructure, and waterway management, causing direct (e.g., waves) and indirect effects (habitat loss, invasions).
Electrical conductivity fluctuations as a tracer to determine time-dependent transport characteristics in hyporheic sediments
The paper presents a modeling approach to estimate time-varying travel times from the stream water to the streambed. The modeling is based on fluctuations in electrical conductivity in the surface water and in the porewater. Given the high temporal dynamics of transport in streambed sediments, the model will be a valuable tool for the assessment of reactive transport in streambed sediments.
Freshwater megafauna shape ecosystems and facilitate restoration
This is a review, synthesizing how megafauna shape ecological processes in freshwater ecosystems and discussing their potential for enhancing ecosystem restoration. Restoring freshwater megafauna can revive essential ecological processes like disturbances, trophic cascades, and species dispersal, boosting biodiversity and enhancing nature's contributions to people.
