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.

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. 

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). 

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.

The authors add a new perspective to the topic of "recreational use of wild animals". The hypothesis is that an emotionally intense interaction between hunters / anglers and wild animals can create a particularly strong sense of responsibility, described as "environmental stewardship". This in turn would be an incentive for many to commit to lifelong environmental and species protection action. 

Conservation efforts have led to the recovery of pinnipeds populations worldwide after decades of intensive hunting and culls. However, this positive development has led to conflicts with fisheries, particularly small-scale fisheries. They are almost three times more likely to come into conflict with seals, sea lions and walruses, and lose four times more of their catch than larger fisheries.

This study investigated how organic micropollutants and the algal toxins prymnesins interact as mixtures in water extracts from the Oder River using neurotoxic effects on human nerve cells in vitro. The authors showed that prymnesins dominate the neurotoxic effects, but many of the detected organic micropollutants exacerbate the lethal effect of prymnesins.

The authors introduce the concept of novel river landscapes, the limitations of current fish habitat models and opportunities for new models. They outline 3 priority data-driven opportunities that incorporate the novel riverscape concept: fish movement, river behavior, and drivers of novelty that all are integrated into a scale-based framework to guide the development of new models.
