Summary: The study demonstrated the effectiveness of monitoring biological impairment in Arctic streams caused by human activities through analyzing benthic invertebrates. It showed that biomonitoring is applicable in Arctic environments and can provide a rapid and cost-effective means of assessing future environmental impact.

Summary: The study found that using underwater cameras equipped with CLOCs can effectively assess marine benthic biodiversity in turbid environments by enhancing image quality, seabed visibility, and habitat identification. Additionally, the use of CLOCs can reduce sampling effort and increase taxonomic richness, improving the overall quality of data collected for informed management decisions.

Summary: Roads form a global network of ecological barriers that have wide-ranging impacts on lotic ecosystems, including fragmentation, hydrological changes, sedimentation, and pollution. This study found that downstream of roads, there were lower densities of total macroinvertebrates and mayflies compared to upstream, while control streams did not show similar effects. Species density tended to be lower downstream, likely due to the lower macroinvertebrate densities at these sites. The species composition and abundances also differed between road impacted streams and control streams, suggesting a selection for different species in road impacted streams. Functional impacts included increased prevalence of predators in control streams and a higher proportion of grazers and shredders in road impacted streams.

Summary: This study aims to provide quantitative data on the early settlement progress of macrofaunal benthic assemblages developing on artificial reefs. The results show that macroalgae consistently dominate in terms of coverage, while sessile invertebrates display different patterns over the years. Ecological succession is ongoing, and further improvement in monitoring methodology is needed for a more accurate assessment of community composition.

Summary: In the Anthropocene, human activities have had a significant impact on ecosystems, particularly in urban areas where rivers have undergone major changes. This study monitored an Andean river in Ayacucho, Peru and used physicochemical parameters, biotic quality indices, and trophic guild components to determine water quality. The results showed that these trophic metrics were highly correlated with established indices, providing a reliable method for assessing river water quality and functionality.

Summary: This study assessed the response of aquatic macroinvertebrate communities to multiple anthropogenic stressors in a lowland river spanning from pristine sectors to densely populated urban areas. A bioassay procedure was developed to evaluate water and sediment quality, with macroinvertebrate organisms correlated with physicochemical parameters and pollutants. Significant changes in physicochemical parameters were found along a longitudinal gradient, with macroinvertebrates showing affinities for specific abiotic factors, highlighting their potential use as reliable ecological indicators.

Summary: In recent years, there has been growing concern about the decline in insect biodiversity, particularly among freshwater insects. To investigate the impact of climate change on freshwater insects, researchers conducted a study covering Central Europe from 1990 to 2018, analyzing shifts in insect abundance and diversity in relation to temperature and precipitation. The study found increases in both richness and abundance of freshwater insects, which were influenced by changes in summer and winter temperatures and precipitation. While this is a positive sign, the overall situation for freshwater invertebrates remains critical.

Summary: This study investigates the dynamic changes of selenium speciation and concentrations in sediments, as well as the accumulation and depuration of Se(IV) and Se-Met in the oligochaete L. variegatus. The findings provide essential data for understanding the ecological risk of selenium to freshwater benthic communities.

Summary: Through comparing ES-eDNA and WS-eDNA metabarcoding techniques in determining freshwater biodiversity and recovering damaged communities, it was found that ES-eDNA metabarcoding performs better in detecting local biodiversity and is consistent with morphological results, while WS-eDNA is more suitable for exploring biodiversity patterns on a broader scale.

Summary: This study determined the body length and biomass of benthic macroinvertebrates in two aquatic environments with different impact levels, finding that the disturbed site had lower biomass. Significant differences in biomass between sites were observed by calculating biomass signatures, suggesting a new method for biomonitoring research.

Summary: Benthic macroinvertebrates are widely used in assessing aquatic ecosystems worldwide, with DNA metabarcoding offering a promising approach to overcome limitations in morphology-based assessments. However, challenges such as lack of standardized protocols and incomplete reference libraries still need to be addressed for more widespread implementation. Benchmarking morphology against DNA and establishing biotic indexes are essential for global adoption and increased confidence from end-users.

Summary: The study calculated and contrasted sixteen indicators of ecological status in a coastal benthic ecosystem in Quebec, Canada, highlighting generally good ecological status with high taxa and functional diversities and without the dominance of opportunistic taxa. Some correlations with habitat parameters, especially heavy metals, were detected, and bootstrap analyses indicated robust results.

Summary: Organisms at the base of stream food webs have a low supply of long-chain polyunsaturated fatty acids (LC-PUFA) such as docosahexaenoic acid (DHA), while consumers at higher trophic levels are rich in LC-PUFA. This study investigated the origins of LC-PUFA in these consumers and found that they are likely obtained through selective retention of dietary sources rather than endogenous conversion. Stable isotopes were used to track the sources of LC-PUFA, with results showing that consumers retained algal-derived PUFA in oligotrophic headwater streams.
