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.

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. 

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. 

This study investigated the formation of reactive species during the activation of the chemical oxidant persulfate with biochar and iron in different water types for the removal of organic contaminants. The presence of organic matter and chloride altered the reactive species formed, emphasizing that the water matrix is a critical factor for the application of this oxidation process .

The authors tested the effect of 3 migration velocities as well as oscillating and constant light conditions on the structure and function of the microbial community residing in sediments from migrating ripple and stationary patches: Light oscillation is the predominating environmental factor during ripple migration, resulting in an increased vulnerability of light-dependent photoautotrophs.

The field study compared sediment characteristics as well as multitrophic diversity and function in two vertical layers of migrating ripples and stationary patches in sandy lowland streams. It indicates that migrating bedforms create streambed heterogeneity by modulating the abundance, diversity, and structure of different trophic guilds of microbial communities and their resource acquisition.
