Attributing Urban Evapotranspiration From Eddy‐Covariance to Surface Cover: Bottom‐Up Versus Top‐Down
Evapotranspiration (ET) is an important process in the water cycle that can help reduce heat stress in cities. However, it is dependent on surface cover. The study provides insights that can inform urban planning and water management decisions, including improving the living environment of city dwellers.
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.
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
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.
Seasonality, rather than estuarine gradient or particle suspension/sinking dynamics, determines estuarine carbon distributions
Multiple-stressor effects on leaf litter decomposition in freshwater ecosystems: A meta-analysis
By using a meta analytical technique, the authors investigated the effect of multiple-stressors on leaf litter decomposition in freshwaters. The overall interaction between multiple stressors was antagonistic and the magnitude and direction of multiple-stressor interactions depends on factors such as the involvement of macroinvertebrates, habitat type and available resources.
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.
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).
The European Reference Genome Atlas: piloting a decentralised approach to equitable biodiversity genomics
Researchers from all over Europe have created high-standard reference genomes for 98 species as part of the European Reference Genome Atlas (ERGA) pilot project. This collaboration of scientists from 33 countries is an important milestone on the way to a reference genome database for European animals, plants and fungi.
