Summary: The concentration of dissolved oxygen in aquatic systems plays a crucial role in regulating biodiversity, nutrient biogeochemistry, greenhouse gas emissions, and drinking water quality. Climate change and human activities have led to declines in dissolved oxygen in lakes, impacting the physical and chemical environment, as well as essential ecosystem services.

Summary: The study reveals that viral community composition in peatlands is influenced by factors such as peat depth, water content, and carbon chemistry, showing distinct aquatic characteristics. Viral populations in peatlands have narrow predicted host ranges. There are strong viral species boundaries between terrestrial and aquatic ecosystems, as well as between different types of soils.

Summary: This study evaluated co-occurrence networks of protistan plankton communities in two temperate deep lakes, revealing that the Lake Zurich plankton communities were less connected, more fragmented, and more susceptible to species extinction scenarios compared to Lake Mondsee communities. The findings suggest a lower robustness of Lake Zurich protistan plankton to environmental stressors, particularly those related to climate change. The network analysis highlighted the importance of the phylum Ciliophora in these communities and indicated species-specific adaptations to environmental conditions.

Summary: This study investigated the distributional patterns of bacterial generalists and specialists along a latitudinal gradient, finding that generalists had wider niches and higher intra-specific variation, whereas specialists experienced decreased abundance and occurrence with increasing latitude. Stochastic processes were the main drivers of community assembly in both groups, with deterministic processes having a greater impact on specialists. Bacterial generalists coexisted through niche differences, while specialists coexisted through fitness differences.

Summary: Macrophytes are essential for lake ecosystems, and this study investigated the factors influencing macrophyte community structure. The results showed that water depth, distance from shore, and sediment texture were related to macrophyte richness, with complex interactions. Management strategies should be tailored to individual lakes.

Summary: Climate change has significant impacts on aquatic ecosystems, including reduced ice cover, longer summer stratified seasons, and a cascade of ecological consequences. These consequences affect water temperature, mixing and water levels, dissolved oxygen, algal blooms, and cold-water fisheries' habitat. Climate change also affects freshwater supplies, water quality, biodiversity, and the ecosystem benefits they provide to society.

Summary: Aquatic hyphomycetes are important decomposers in freshwater environments and their diversity is influenced by the subtropical-tropical gradient. This study found higher species richness and fungal biomass in subtropical streams compared to tropical streams. Environmental factors such as temperature, pH, electrical conductivity, and dissolved oxygen levels had negative effects on spore production.

Summary: Changing ecological conditions along environmental gradients influence patterns of biodiversity and ecosystem functioning. Aquatic food webs along stream gradients were studied to understand how networks of interacting species respond to these changes. The study found that while increasing ecosystem size, productivity, and species richness influenced trophic diversity, there was a nonlinear relationship between trophic diversity and the gradient. Trophic redundancy within the fish community decreased downstream along the gradient, but this relationship varied with fish species richness. Overall, this study highlights the importance of understanding the mechanisms that shape food web properties along gradients and their implications for ecosystem function in the face of environmental change.

Summary: The study found clear geographical patterns of ecoregion robustness for North American freshwater plants, with communities being more internally homogeneous and similar in Polar and Subtropical inland waters. The degree of internal homogeneity and ecoregion distinctness were mainly driven by species replacements and richness differences, and ecoregion delineation performed best for emergent and floating-leaved plants in different life-forms.

Summary: This study provides the first global synthesis of taxonomic and functional distance decay along spatial and environmental distance. The results demonstrate that taxonomic distance decay is stronger than functional distance decay, with the fastest decay rates observed in datasets from mid-latitudes. Overall, taxonomic distance decay is a useful tool for biogeographical research, while functional distance decay may be a cost-effective option for investigating community changes in heterogeneous environments.

Summary: Currently, there is a need for comprehensive approaches in biodiversity conservation due to global environmental change. Recent research suggests that considering the diversity of Earth's abiotic features (geodiversity) can provide new insights and applications in investigating and managing biodiversity. However, methods to map and quantify geodiversity at a local scale have not been developed, even though this scale is important for conservation planning. In this study, a field methodology for observing plot-scale geodiversity is introduced and pilot-tested in an Arctic-alpine tundra environment. The results provide empirical evidence of the relationship between plot-scale biodiversity and geodiversity and offer guidance for practitioners on implementing the method.

Summary: This study evaluated the responses of multiple facets (taxonomic, functional, and phylogenetic) of freshwater molluscs to the loss of lateral hydrological connectivity in floodplain lakes in the Yangtze River Basin. The results showed that functional diversity was significantly higher in connected lakes compared to disconnected lakes, indicating a high level of functional diversity loss without replacement. Lake area, hydrological connectivity, aquatic vegetation coverage, and nutrient levels played important roles in shaping molluscan alpha and beta diversities.

Summary: This study examines breakpoints in the community composition of freshwater plants across continents and finds that there is an abrupt transition between temperate to boreal regions and freshwater plant communities with subtropical or Mediterranean assemblages. The study suggests that the spatially structured variation in current climatic conditions is the main driver of these latitudinal patterns, although eco-evolutionary constraints and post-glacial migration lags may also play a role.

Summary: Changes in natural land cover and intensified land use have led to concomitant changes in abiotic templates and biotic communities of ecosystems in boreal landscapes. This review focuses on the historical impacts of land use on boreal lakes, considering lake features related to abiotic conditions, biological communities, and ecosystem services. A novel approach using the alpha, beta, and gamma concept is proposed to characterize lake features, and potential solutions for lake management and conservation in a landscape setting are provided. This approach can help identify lakes for ecosystem services ('lake-sharing') and for protecting aquatic biodiversity ('lake-sparing').

Summary: By resurveying vegetation in different boreal habitat types in Rokua National Park in Finland, we found that the compositional similarity of plant communities has increased over time, mainly due to an increase in forest species and the loss of habitat-specific species. Our study highlights the importance of proper management in achieving long-term biodiversity conservation goals in protected areas.

Summary: Our existence on Earth depends on the vital support of nature for our physical and mental health. However, the importance of geodiversity, the diversity of non-living nature, has been overlooked compared to biodiversity. Geodiversity, consisting of geological, geomorphological, soil, and hydrological components, forms the foundation for biodiversity and is necessary for overall human health. This article introduces geodiversity as a driver for planetary health, describing its functions and services, and exploring the intricate relationships between geodiversity, biodiversity, and human health. It also proposes an agenda for recognizing the importance of geodiversity in health-related research and decision making. Geodiversity is an emerging topic with untapped potential in ensuring ecosystem functionality and good living conditions for people in a changing environment.
