The authors review how different bat guilds respond to artificial light at night (ALAN) and assess how the impacts vary according to ecological context. All studied European species respond for example negatively to a wide range of light colors and intensities close to roosts and drinking sites. The sprawl of ALAN may be a key factor driving the decline of bat diversity.

The authors introduced a novel numerical modelling framework that provides reactive parameter estimates of contaminant transformation reactions with high parameter identifiability and informs dominant transformation pathways for joint parent daughter simulations in river sediments. The findings highlight that the daughter reaction rate may be underestimated if its parent transformation is ignored.

The authors studied Isotopes in Berlin’s Panke catchment to understand stream flow sources. Groundwater dominated the upper catchment, but ~90% of flow in the lower catchment was treated waste water. High flows were generated from urban drains. The stream has unnatural hydrological and chemical regimes with restoration needed for improved ecology. 

The authors investigated the seasonal dynamics in prokaryotic and eukaryotic microbiomes in three common fen types in Northern Germany. The eukaryotic microbiomes showed significant changes in their community structures across the seasons in contrast to largely unaffected prokaryotic microbiomes. The dynamics in eukaryotic microbiomes in the rewetted sites differed between fen types.

The scientist allowed sediments of a nutrient-rich lowland river to dry out over 9 weeks to study temporal changes of microbial activity, carbon dioxide and methane emissions, and of the fluxes of water-soluble organic carbon. They also simulated short rainfalls on the dried-up riverbed. The study shows, that after drying up and raining, rivers can release more carbon dioxide and methane.

Rewetted peatlands have the potential to fulfil the restoration goals including those targeting climate change mitigation, water quality protection, and species conservation. However, due to heavy soil changes their restoration cannot be expected in short-term. Data analyser of several hundred natural and degraded peatlands have shown that it might last decades before they become fully recovered.

Using a survey of 20 zooplankton communities, population genetic and phenotypic trait data the authors quantified the impact of local trait evolution of Daphnia magna on zooplankton community trait values. They found spatial variation in the impact of local evolution of D. magna that could be explained by ecological community features rather than by population genetics or environmental features. 

Explosive growth in “environmental DNA” studies has led to inconsistent use of the term “eDNA”. The confusion could jeopardize research, conservation, and management efforts. The authors argue that eDNA should be defined by its origin rather than by methods used to detect it, and that studies must clearly distinguish between eDNA from whole organisms and from trace amounts found in shed cells.
