Summary: Soil bacterial communities in a coastal area follow a distance-decay relationship and the distribution is influenced by body size. This study collected soil samples from two adjacent ecosystems and found that the entire microbial community, as well as individual taxonomic groups, exhibited distance-decay patterns. The turnover rate of microbial communities was higher in nontidal soils and topsoil, with body size influencing the spatial limitation in nontidal topsoil but not in tidal soils.

Summary: This study found that the spatiotemporal variability in water microbial communities is influenced by relic DNA. After removing relic DNA, the composition of microbial communities showed significant changes, especially for microeukaryotes. Moreover, relic DNA removal also altered the relationships between microeukaryotic community composition and environmental factors. Therefore, more studies on the abundance, decay rate, and functioning of nonviable DNA in freshwater ecosystems are recommended in the future.

Summary: The conversion from pure coniferous stands to mixed forests is an important goal in forest management strategies due to climate change, yet its effects on species diversity and the driving factors remain unclear. This study investigated the effects of forest conversion on diversity by establishing plots in a managed forest in Germany. The results showed that forest structure and environmental conditions during conversion, as well as the introduction of beech, have significant impacts on alpha and beta diversity of various taxa.

Summary: Climate can influence the timing of life events. Studies from around the world show that climate cues and species' responses can vary. We collected data on phenological events for multiple species in a high-elevation environment over 45 years and found significant variation in how climate affects phenology across taxa. Comparing the phenological responses of different taxa at a single location, we found that important cues often differ among species, which suggests that climate change may disrupt the synchrony of timing among taxa.

Summary: Recent studies have shown the usefulness of diatom eDNA metabarcoding for assessing river and stream ecological quality. However, differences in taxonomic markers and data analysis methods hinder result comparison. This study compared two taxonomic markers and three analytical approaches and found that taxonomy-free methods were more correlated with morphological index values, with rbcL marker showing higher correlations than 18S marker.

Summary: The study found that a short-term drought can reduce taxonomic richness and abundance of invertebrates, but not affect functional diversity. There is a high degree of functional redundancy in benthic invertebrate communities, allowing for maintenance of functional diversity despite species losses. Different feeding groups respond differently to drought, with organic matter decomposers being most affected.

Summary: Ecosystem functioning and community structure are key components of ecosystem integrity. However, there is a lack of comprehensive studies on the responses of structural and functional indicators to different anthropogenic pressures. This study investigated the variation in community structure and ecosystem functioning along gradients of agriculture, forestry, and river regulation. The findings highlight the challenges of inferring the impacts of anthropogenic disturbances based on community data alone and emphasize the need for optimal sets of indicators to detect ecological changes associated with different human activities.

Summary: Globalization has led to the introduction of numerous alien species worldwide. Understanding the invasion process and its impacts is crucial for effective management. This study proposes an impact curve based on cumulative abundances to describe the effects of invasive species over time. Empirical testing using data from the New Zealand mud snail in Europe shows that 59% of populations follow the impact curve, characterized by initial occurrence, exponential growth, and long-term saturation.

Summary: In freshwater habitats, invasive species and the increase of cyanobacterial blooms are causing biodiversity loss. Raphidiopsis raciborskii, a toxin-producing cyanobacteria species, is expanding its range across Europe. By using species distribution models and bioclimatic environmental variables, suitable areas for colonization and survival of R. raciborskii, especially in Northern Europe, were identified. This study provides valuable information for monitoring and prevention efforts to control the spread of R. raciborskii.

Summary: Since the mid-20th century, Europe has seen a significant increase in non-indigenous crayfish species (NICS) due to their extensive use in fisheries, aquaculture, and pet trade. However, there is a lack of large-scale analysis on their occurrences and trends. In this study, using a freshwater macroinvertebrate database, we evaluated the information on NICS obtained from biomonitoring approaches and identified species-specific trends. We found no significant temporal trend for the abundance of any species at the European scale but identified predictors of abundances.

Summary: Due to historical anthropogenic pressures, freshwater ecosystems are highly vulnerable to biodiversity loss. Mitigation efforts, such as wastewater treatment and hydromorphological restoration, aim to improve environmental quality and restore freshwater biodiversity. This study analyzed 1,816 time series of freshwater invertebrate communities across 22 European countries from 1968 to 2020. The findings reveal overall increases in taxonomic and functional diversity and abundance, but these increases have plateaued since the 2010s. Communities downstream of dams, urban areas, and croplands show lower chances of recovery. Faster rates of warming are associated with lesser gains in biodiversity. Additional mitigation measures are needed to revive the recovery of freshwater biodiversity in response to emerging pollutants, climate change, and invasive species.
