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: Traditionally, lakes are classified based on their thermal regime and trophic status, but this classification method is not sufficient to understand seasonally ice-covered lakes. Research has found that differently sized and deep seasonally ice-covered lakes exhibit different thermal stratification characteristics, leading to the proposal of new classification terms.

Summary: This paper evaluates the univariate and compound extreme events in lakes worldwide using satellite observations, revealing that the intensity of lake heatwaves and high chlorophyll-a extremes varies across lakes and is primarily influenced by the annual range in surface water temperature and chlorophyll-a concentrations. Compound extreme events occur more frequently than assumed in most studied lakes, potentially causing more severe impacts on lake ecosystems than previously reported due to the occurrence of univariate extremes.

Summary: This study presents a scaling relationship between tributary length and lake area based on the principle of line intercepts of topographic features. The theory is tested using data from Scandinavia and shows that tributary length increases by 73% for each doubling of lake area. Additionally, factors such as inlet frequency, junction angle, and lake shape also influence this scaling relationship.

Summary: The greening and browning of global vegetation are influenced by multiple processes, including climate change, CO2 fertilization, and land management. Based on the vegetation-water-heat relationship, these processes can be categorized into two types of eco-hydrological processes: dryness change and usage change. By analyzing remote-sensing data and climate data, it has been found that dryness change has become the dominant factor in climate change impacts on vegetated lands globally, leading to a fundamental weakening of global greening.

Summary: Large herbivores have significant ecological impacts, but research findings are often conflicting and uncertain. They consistently control plant dynamics, species composition, biomass, and suppress fires and smaller animal abundance. However, the effects on predation risk, trophic cascades, seed dispersal, and biogeochemistry are less clear. The role of body size in regulating ecological impact is important, and losing large-herbivore species will alter net impact.

Summary: Ecological stoichiometry is an efficient tool for exploring the balance and cycling of coupled elements. C:N:P ratios are essential in ecological models of productivity or C cycling. This study comprehensively calculated C:N:P ratios from organs to ecosystems in 66 typical natural ecosystems in China using the community biomass-weighted mean (CWM), showing significant differences among ecosystem types and biomes. Environmental conditions explain a substantial portion of the spatial variation of C:N:P ratios from organs to ecosystems.

Summary: Lake surface water temperature is highly sensitive to climate change and is found to be warming globally. The warming rate of global lakes varies by region, with dryland lakes experiencing more significant warming compared to semi-humid and humid regions. Air temperature is identified as the main driving force for lake warming. Future projections indicate that lake surface water temperature will continue to rise, especially in dryland areas.

Summary: The study shows that crossing the salinity barrier allows organisms to access new ecosystems and experience significant shifts in diversification rates while adapting to changes in selective pressures. Analysis suggests that freshwater environments have triggered four independent transitions since the mid-Miocene, with ancestral euryhaline species adapting to fluctuating salinity levels.

Summary: Research conducted at Ny-Alesund in Svalbard, Norway for over 50 years has aimed to understand the structure and functioning of High Arctic ecosystems and the impacts of environmental change. The research has identified negative effects of climate change on biodiversity and ecosystem processes, while highlighting knowledge gaps for smaller organisms and ecosystem-level processes. To fill these gaps, recommendations include long-term ecosystem-based monitoring, mechanistic understanding of environmental change impacts, studying trophic interactions and cascades, and integrating long-term data on microbial communities and nutrient fluxes.

Summary: By studying pond ecosystems in two different geographical regions of the world, it was found that temperate ponds are more influenced by environmental and spatial factors, while tropical ponds are more influenced by climatic variability and dispersal processes. The relative importance of space and environment varies greatly among different taxonomic groups, with active dispersers being more influenced by the environment and passive dispersers being more influenced by spatial factors. These results support the classic view of stronger abiotic niche constraints in temperate areas compared to the tropics.

Summary: The protection of biodiversity and ecosystem values in Antarctica is outlined in the Protocol on Environmental Protection to the Antarctic Treaty, which establishes Antarctic Specially Protected Areas (ASPAs) for areas with exceptional values. However, there is concern that existing ASPAs do not prioritize areas effectively for long-term conservation. This paper argues for the inclusion of inland waters in the ASPA framework to address their underrepresentation and proposes a structured approach for their selection, taking into account the limited knowledge of inland aquatic diversity and the need to consider catchment-scale processes.

Summary: Recovery, recolonization, and adaptation are processes that regenerate local populations and communities after chemical stress. Recolonization involves the dispersal of organisms from other areas to fill empty niches, while adaptation refers to phenotypic and genetic changes that allow the persistence of existing taxa. Understanding the relative importance of these processes is crucial for the regeneration of biological communities after chemical exposure. This study provides case studies and recommendations to assess and compare the importance of these processes for risk assessment and ecosystem management.

Summary: This study compares the diversity of multiple taxa inhabiting tropical and Mediterranean temporary ponds using a spatial and temporal approach. The results show higher gamma and alpha diversity in tropical ponds, but phytoplankton and microinvertebrates from the Mediterranean region matched or exceeded tropical alpha diversity on some occasions. Spatial beta diversity did not differ between regions, and temporal beta diversity showed similar patterns. However, macroinvertebrates and amphibians exhibited differential effects on community variation observable only in animals with longer life-spans.
