Summary: Peatlands in the northern hemisphere have been drained but restoration efforts have been made to raise water tables and enhance biodiversity. This study analyzed the response of aquatic invertebrates to peatland restoration through several approaches. Invertebrate communities established quickly after pond creation, but their diversity and abundance peaked at around 5 years before declining. The environmental conditions and biodiversity of older ponds were similar to natural ponds, indicating restoration success for aquatic biodiversity gains.

Summary: Periods of streamflow cessation and drying are increasing globally. The heterogeneity of habitat conditions is a key control on the variability of benthic macroinvertebrate (BMI) communities in streams with intermittent flow. Unlike other studies, BMI richness, diversity, and abundance were consistently higher at intermittent riffle sites than perennial riffle sites, which were similar in BMI community composition to pool sites.

Summary: While climate change affects ecosystems globally, not all ecosystems respond in the same way. The resilience of ecological communities may depend on the energy pathways of food webs. Studies show that communities with multiple energy pathways are more stable and more resistant to disturbances like climate change. In particular, this study found that food webs based on green energy sources showed higher overall resilience to drought compared to mixed or brown energy sources.

Summary: Marine classification schemes are often used in marine conservation planning, but may not accurately represent biological patterns. In this study, a community-level modeling approach was used to characterize and delineate fish and invertebrate assemblages in the Northwest Atlantic. The modeling accurately predicted assemblage distributions and identified important predictors of distribution. The study also projected future distributions under a high emissions climate scenario and highlighted the importance of combining modeling with oceanographic forecasts for improved conservation planning and management.

Summary: The effects of 1-μm polystyrene (PS) beads on the reproduction of Caenorhabditis elegans in freshwater sediments were studied using a standardized protocol for toxicity testing. The results showed that the body burdens of PS beads in the nematodes differed between sediments, but not significantly. The ECx-values for C. elegans' reproduction varied among different sediments and were higher than values reported for water exposure, indicating that microplastic reduces food availability and affects reproduction in benthic ecosystems.

Summary: Heterogeneous glacial deposits play a dominant role in many areas of the Northern Hemisphere. Crosshole ground penetrating radar (GPR) is proposed as a valuable tool for studying contaminant transport in these landscapes. In this study, GPR data collected at an industrial contaminated site in a clay till setting were processed using a novel inversion approach. The results were compared to borehole logs, grain size analyses, and permeability data to evaluate the effectiveness of GPR in characterizing geological variability. The findings suggest that GPR has the potential to provide high-resolution geological information and fill the data gap between boreholes in contaminated site investigations.

Summary: C. elegans is commonly used to assess the toxicity of chemicals in aqueous medium. However, the binding of chemicals to bacterial food decreases their freely dissolved concentrations, leading to an underestimation of toxicity. This study found that simple partitioning models can be used to estimate freely dissolved concentrations and that the toxicity of organic chemicals on C. elegans is weakly related to their hydrophobicity. The findings suggest that routine testing and comparison of chemicals can be more accurate by considering freely dissolved concentrations.

Summary: As societies and natural systems become more interconnected, sustainable management needs to adapt to new knowledge from both ecological and social domains and act on it effectively. The Anthropocene and approaching the limit for humanity's safe operating space highlight the need for better information feedbacks between science, policy, and society. The Drivers-Pressures-State-Impacts-Response (DPSIR) framework can support sustainable policy development and implementation, but its focus on analytical and procedural aspects should be made explicit for more effective coordination across silos and studies.

Summary: This study investigated methods for predicting the duration and impact of persistent and mobile organic compounds (PMOCs) on groundwater quality at a drinking water well field affected by multiple contaminant sources. The study used the fungicide metabolite N,N-dimethylsulfamide (DMS) as an example, and made important discoveries by combining contaminant mass discharge (CMD) estimations, modeling, and groundwater dating. The study found that the current center of contaminant mass was near the source area, and predicted that CMD at the well field would peak in 2040 with an impact on groundwater quality expected until the end of the 21st century. The study also identified an additional pesticide source that had not yet been thoroughly investigated.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
