Summary: This study investigates the interactive effects of dam construction and nutrient enrichment on river ecosystems using environmental DNA (eDNA) approach. The results reveal that dams and nutrients jointly shape the spatial patterns and community structures of aquatic communities, and additive, synergistic, and antagonistic interactions are commonly observed. Additionally, nutrients have a stronger impact on certain taxonomic groups, such as protozoa, fungi, and eukaryotic algae, while dams have a stronger effect on fish, aquatic insects, and bacteria.

Summary: Human-driven environmental stressors pose an increasing threat to species survival and diversity in river systems worldwide. This study investigated the effects of persistent stressors, including land use and pollutants, on multiple communities in a human-dominated river in China over a 3-year period using environmental DNA (eDNA) data. The results showed that persistent stressors significantly reduced species diversity and stability, but increased species synchrony across multiple communities. The structures of interaction networks were also affected, leading to decreased modularity and cohesion. The decline in stability of multiple communities was mainly attributed to diversity-mediated pathways, such as increased species synchrony and changes in interaction networks.

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: Perceptions related to the importance of genetic research have an impact on the use of genetic tools and concepts in conservation actions. The views and expertise of stakeholders, as well as their knowledge and social connections with geneticists, influence the application of genetic information in management practices. In this study, aquatic invasive species (AIS) specialists were surveyed to assess their perceptions of the importance of genetic tools and concepts, and the suitability of genetic biocontrol. It was found that genetic knowledge was the strongest predictor of higher importance ratings, while support for gene editing varied depending on geographic location and specialists' knowledge of genetics and AIS management.

Summary: Globally, river pesticide concentrations are associated with declines in regional and local stream invertebrate diversity. However, the effects of pesticides in Asian freshwater ecosystems have been less studied. This study in India found that malathion had a major effect on river invertebrate communities, while nutrients and sediments had lesser effects. Comparisons with other regions suggest that Indian taxa are relatively tolerant to pesticides.

Summary: Environmental DNA (eDNA) sampling is a powerful and efficient approach for collecting information about species, and it may also provide information about population-level genetic variability. In this study, the researchers used eDNA sampling to estimate the genetic diversity and structure of an invasive fish species in the Great Lakes region. The study found that the genetic patterns observed from eDNA analysis were consistent with conventional tissue-based estimates. This research highlights the potential for eDNA sampling to reveal detailed population characteristics that can inform monitoring and management plans for difficult-to-sample species.

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.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
