Summary: The worldwide decline in freshwater biodiversity due to anthropogenic pressures is a growing concern, as it leads to loss of ecosystem functions. This study aimed to evaluate the changes in freshwater mussel diversity, density, and biomass in the Poyang Lake basin over the last 60 years and identify the factors driving these patterns. The results showed a decline in alpha diversity, species richness, density, and biomass of freshwater mussels, indicating a homogenization of their populations. The study also found a significant association between pH and biodiversity, suggesting that acidification due to intensive agriculture development may be a major factor behind the decline of freshwater mussels.

Summary: In the neotropics, potamodromous fish species are severely impacted by dams. However, free-flowing tributaries contribute to the reproductive migration and recruitment of migratory fish. Genetic diversity and population structure of Pimelodus maculatus were assessed in seven reservoirs and nine tributaries, and the findings supported the idea that free-flowing tributaries contribute to wider population distributions, larger effective population sizes, and satisfactory genetic diversity levels.

Summary: River barriers, such as dams and reservoirs, have significant impacts on river dynamics and aquatic ecosystems. The importance of these barriers lies in the services they provide, such as water supply and low-carbon energy, which are increasingly critical due to climate change. A study conducted in two regions in Spain with contrasting climates and water security found that support for dams was higher in the drier region, where water shortages are more common. However, awareness of the impacts of dams was also higher in this region, indicating the need for involving local citizens in decision-making processes regarding water management.

Summary: The decline in insect populations has been a topic of intense discussion among experts, policymakers, and the public. Despite the long-reported decreasing trends in Europe and North America, there is still controversy over the specific drivers and pressures behind this decline. This is due to the complex interplay of biotic and abiotic factors, as well as anthropogenic activities, that impact habitats, communities, populations, and individual organisms. Recent publications aim to identify the extent of the decline and the potential drivers, highlighting the role of agriculture, climate change, nature conservation activities, urbanization, and other human activities. However, there is a lack of scientific data and monitoring on the pressures contributing to the decline in insect populations, highlighting the need for further research and monitoring.

Summary: The study suggests that increases in suspended sediment can have negative impacts on freshwater unionid mussels, including decreasing food availability, interfering with filter feeding and respiration, and impeding the mussel-host relationship. Thresholds of sediment concentrations that cause significant declines in population performance were identified, serving as reference points for ecological research and management. The research also found specific thresholds at which impacts on feeding, respiratory stress, fertilization success, larval development, and reproductive failure occurred, providing valuable information for understanding the potential impacts of sediment on mussel populations.

Summary: The Balkan region has well-conserved rivers, but faces conflicts between promoting renewable hydropower and prioritising river conservation. To resolve this conflict, reliable information is needed. Using barrier data, the study analysed river fragmentation and simulated dam construction scenarios. The findings show that all dam construction scenarios would result in a loss of connectivity, with the largest loss occurring if all planned dams were built, and small dams contributing disproportionately to fragmentation.

Summary: Europe's freshwater ecosystems have been under human pressure for a long time. With increasing pressure and emerging threats, there is an urgent need to conserve freshwater biodiversity and its ecosystem services. However, while some taxonomic groups, mainly vertebrates, have received disproportionate attention and funding, other groups, like freshwater mussels, remain largely overlooked. This article points out six conceptual areas that require immediate and long-term attention to address this conservation bias, including knowledge, threats, socioeconomics, conservation, governance, and education. The proposed roadmap aims to prioritize research, policy, and education for the conservation of freshwater mussels in Europe.

Summary: This study aimed to assess the role of environmental and biotic drivers in determining the distribution of freshwater mussels and their fish hosts. The results showed that the distribution of mussels was mainly influenced by environmental factors such as climate, topography, and land use. Co-occurrence patterns between mussels and fish hosts were mainly influenced by residual factors, indicating the potential role of biotic interactions. By identifying important fish hosts based on distributional data alone, conservation measures can be targeted towards multiple species, leading to a more holistic approach to biodiversity protection.

Summary: Corbicula fluminea is a widespread and problematic invasive bivalve species in freshwater ecosystems. Most studies have focused on toxicology and ecology, primarily in North America and Europe. However, there is still a lack of understanding about its basic biological and ecological features and the mechanisms underlying its impacts in invaded areas. Therefore, there is an urgent need for novel methodologies and techniques to improve early detection, spread prediction, and effective management for containment and eradication of this species.
