Summary: This study compared and evaluated four different indices of biotic integrity using stream fish community data, and found that the relationships among the indices varied across different management jurisdictions. The indices showed different sensitivities to changes in community composition due to replacements of native with non-native species and year-to-year species turnover. Resampling through bootstrap analysis showed the potential to significantly change resulting scores and alter stream health designations. Therefore, the potential advantages and limitations of indices of biotic integrity should be considered when selecting and using them in a given region.

Summary: The study highlights the considerable variation in health status assessments resulting from different scoring and classification methods in developing the Index of Biotic Integrity (IBI). The wetland health of Poyang Lake was rated as fair, indicating anthropogenic pressure and substantial changes in macroinvertebrate assemblage structure have impacted the wetland.

Summary: The study reveals that anthropogenic pollution has a negative impact on the ecological state of the Nidda River, leading to liver lesions and abnormal function of the CYP1A1 system in fish. There is minimal variation between seasons and sampling sites, but it was observed that liver condition is poorest during the spawning season and downstream of industrial dischargers, tissue integrity and EROD activity are most affected. Different fish species show varying sensitivity to pollution, with brown trout being the most impacted and European chub being less affected.

Summary: This study aimed to develop Fish Indices of Biological Integrity (FIBIs) and ecologically meaningful thresholds for a broader suite of Minnesota lakes. By sampling fish communities in 419 lakes and evaluating a suite of potential metrics, four FIBIs were successfully developed with Biological Condition Gradient (BCG) models and thresholds established for impairment and exceptional conditions. These FIBIs and thresholds are now being utilized for clean water planning, restoration, and protection efforts in Minnesota lakes.

Summary: Anthropogenic activities have impacted the ecological health of rivers by altering physical habitat, water flow, and causing pollution. The use of fish-based index of biotic integrity (IBI) was employed to assess the health status of the Central Indian river, Tapti. The study revealed that three-fourth of the river stretch was moderately impaired, with the most deteriorated site being Kamrej, possibly due to high influx of domestic sewage and industrial effluents. Proper management and mitigation measures are urgently needed to restore the health and wealth of the aquatic ecosystem.

Summary: For the sustainable use of lake ecosystem services, it is important to assess the ecosystem health using zooplankton as indicators. Zooplankton play a crucial role in material circulation and have interactions with other communities. This review summarizes useful zooplankton indices for ecosystem health assessment and discusses the practical application of measuring zooplankton biomass and the potential of eDNA as a monitoring tool.

Summary: This study used eDNA metabarcoding to monitor fish diversity in the Dianchi Lake basin and constructed the Fish Index of Biological Integrity (F-IBI) for ecological assessment. The results showed distinct diversity patterns among Dianchi Lake and the three inflowing rivers, and water temperature, chemical oxygen demand, total nitrogen, and total phosphorus significantly influenced the distribution of fish communities. According to the F-IBI assessment system, 25% of the sampling sites were defined as 'fine' or above, and 75% were 'impaired' or below.

Summary: The Biotic Integrity index (IBI) was used to assess the health of the Subang Reservoir's aquatic ecosystem by evaluating the freshwater fish. The study found that the ecosystem of the reservoir is under some stress due to an imbalanced fish guild, but overall it is in fair condition. The implementation of biomonitoring can be improved by modifying techniques and increasing its usage in Malaysia's freshwater ecosystems.

Summary: This study identified cryptic tolerant species using a dataset of stream fish and land cover data, and compared two indices of stream health. The results indicated that the proportion of cryptic tolerant species decreased with an increasing proportion of forested land, while the proportion of true sensitive species increased. However, both indices had a low correlation with expected disturbance levels.

Summary: Diclofenac is a widely detected pharmaceutical substance in European water bodies, with limited veterinary uses in Europe and wastewater being the main exposure pathway. The European Commission prefers a deterministic approach for deriving Environmental Quality Standards, while this paper suggests using an evidence-driven probabilistic approach instead.

Summary: This study analyzed how the community structures of fish, macroinvertebrates, and plankton in the Ganjiang River system respond to environmental variables. Multiple indices of biotic integrity were applied to evaluate the health status of the aquatic ecosystem. The results showed that different indices indicated different health statuses and were influenced by different environmental factors. Comprehensive assessments based on multiple groups were found to better characterize the impacts of environmental pressures on water ecosystems.

Summary: The Beibu Gulf, one of the most productive fishing grounds in the world, is experiencing rapid decline in its biotic resources due to overexploitation. The study assesses the health status of its fisheries' resources and reveals that anthropogenic disturbances, particularly overfishing, have had a serious impact on the fish community. It suggests that strict and enforceable fishery management measures should be implemented by China and Vietnam to prevent further deterioration of the resources in the gulf.

Summary: Sustainable agricultural practices are increasingly important for global and national environmental policies and economy. This study compared the sustainability of grape production under integrated and organic management using multiple indicators. The results showed that organic management was more beneficial for most environmental aspects of the agroecosystem compared to integrated management, without affecting grape yield.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
