Summary: This study used epifluorescence microscopy and 16S rRNA metabarcoding to assess the horizontal-spatial abundance and community structure of freshwater picocyanobacteria (Pcy) in two contrasting lakes in New Zealand. Significant differences in Pcy abundance and community composition were found between and within oligotrophic and hypertrophic lakes, with spatial variability particularly pronounced in the oligotrophic Lake Wanaka. The study suggests that single spot-samples are insufficient to understand Pcy dynamics and phytoplankton dynamics in lakes.

Summary: In this study, environmental DNA (eDNA) metabarcoding was used to monitor invertebrate outbreaks at different stages of drinking water treatment. The composition of invertebrate eDNA communities reflected the source water communities in earlier stages, but some dominant taxa were introduced during purification and eliminated in later stages. The study also assessed the detection/quantification limits and read capacity of eDNA metabarcoding for biocontamination surveillance in drinking water treatment plants (DWTPs). A novel eDNA-based approach for sensitive and efficient surveillance of invertebrate outbreaks in DWTPs was proposed.

Summary: Dietary metabarcoding technology has greatly improved the analysis of animal diets, but technical limitations, such as uneven DNA amplification, hinder its application. This review explores various approaches to overcome the predator problem, from deeper sequencing to excluding predator DNA during PCR, and their potential impact on multipredator-taxon studies. The use of multiprimer strategies that prioritize both depth and breadth of prey detection is suggested as a partial solution, although multitaxon studies still require further consideration. Alternative methods for reducing the prevalence of predator DNA are also discussed, highlighting the need for additional empirical examination.

Summary: A major limitation of current reports on insect declines is the lack of standardized, long-term, and taxonomically broad time series. This study demonstrates the utility of environmental DNA from archived leaf material to analyze temporal changes in plant-associated arthropod communities. The results suggest that insect decline may be driven by beta-diversity decay across space and time, resulting in gradual community turnover and biotic homogenization.

Summary: Environmental DNA (eDNA) metabarcoding is transforming aquatic biomonitoring by sequencing DNA/RNA to identify entire communities within a targeted group. Most studies have focused on water eDNA and macroinvertebrate samples, but eDNA metabarcoding has also been applied to soft sediment samples, especially for microbial or meiofaunal communities. Compared to traditional methods, eDNA metabarcoding offers advantages for assessing sediment environmental quality. However, there is a need for standardization to improve robustness and comparability. This review focuses on sampling, preservation, and DNA extraction protocols for sediment eDNA metabarcoding, aiming to identify best practices and promote harmonization for future benthic monitoring.

Summary: Lakes are important for ecosystem services and biodiversity, but cultural eutrophication remains a major threat to their health. The lack of long-term monitoring records limits our ability to manage lake eutrophication. This study developed a bio-indicator approach using diatom communities to infer trophic levels in lakes, and the results were consistent with monitoring data and land-use histories. However, recent shifts in diatom communities were not captured by traditional trophic level indices, highlighting the importance of new approaches in preventing the decline of lake ecosystems worldwide.
