Summary: The study aimed to investigate the impact of biochar on soil carbon, nitrogen, methane emissions, water-extractable organic matter, and nutrient content. Results showed that biochar increased soil carbon levels but did not significantly affect water-extractable organic matter or N2O-N and CH4-C emissions. Co-applying biochar with NP fertilizer appeared to enhance soil phosphorus availability.

Summary: Irrigation can both cool and warm air temperature depending on the balance between daytime cooling and nighttime warming. Evaporative cooling and reduced solar radiation during the daytime can lower air temperature, while the increased atmospheric water vapor at night can enhance the local greenhouse effect and increase nighttime temperature. It is important to consider sub-daily processes when assessing the impact of irrigation on daily air temperature and temperature-related socioeconomic phenomena.

Summary: Biochars have limited long-term effects on plant nutrient contents, nutrient uptake, and crop biomass yield in boreal agricultural soils. However, significant interactions between biochar and fertilization were observed in some cases, leading to increased crop biomass yield when biochar was combined with normal fertilization rates. Despite some positive effects, the overall impact of biochar on crop biomass yield was not significant over the years.

Summary: The symbiosis between methane-oxidizing bacteria (MOB) and photoautotrophs can provide energy and carbon for the freshwater food web. Methane oxidation affects the accumulation of inorganic carbon and the release of exometabolites, influencing the structure of phytoplankton communities. However, there is limited research on the role of these interactions in freshwater ecosystems.

Summary: Research shows that wetland CO2 and CH4 emissions have opposite seasonal temperature dependencies, with CO2 emissions decreasing with increasing monthly mean temperature and CH4 emissions showing the opposite pattern. Neglecting this seasonal temperature dependence may lead to an overestimation of wetland greenhouse gas emissions.

Summary: Using a static chamber-gas chromatography method, this study investigated the characteristics of soil CO2, CH4, and N2O fluxes and their relationships with environmental factors in four types of Larix gmelinii forests in the Greater Khingan Mountains. The study found that all four forest types were sources of CO2 emissions, with similar average emission fluxes. The moss-Larix gmelinii forest emitted CH4, while all other forest types acted as CH4 sinks. Although all forest types showed N2O uptake at the beginning of the growing season, they all acted as sources of N2O emissions for the entire growing season. The fluxes of CO2, CH4, and N2O were significantly correlated with soil temperature and soil pH for all four forest types.

Summary: The impact of gas released from coal fire combustion on the spatial-temporal distribution of CO2 and CH4 and other greenhouse gas emissions was studied in Xinjiang. Using Landsat 8 and GOSAT satellite data, the impact of regional coal fire on CO2 and CH4 emission flux was comprehensively evaluated. The results showed that CO2 and CH4 emissions in Xinjiang were generally dispersed and locally concentrated, with higher intensity in coal fire concentrated areas. The results provide a reference for coal fire control and carbon emission reduction.

Summary: The rapid urbanization of cities has led to the deterioration of urban forests and the loss of benefits from green infrastructure. Citizen participation in the design and management of urban forests can guide cities towards a more sustainable and resilient model in the face of climate change. Citizen perception and appropriation are important for the co-management of parks.

Summary: The relationship between shallow lake chlorophyll-a and nutrient enrichment is not in line with the theory of alternative stable states. This study combines empirical data and simulations to show that a predictable linear relationship between nutrient concentration and chlorophyll-a becomes evident when observed over a longer time period (>3 years), suggesting the absence of alternative stable states.

Summary: Shallow lakes produce and emit significant amounts of methane, and methane-oxidizing bacteria play a role in reducing these emissions. However, the role of aquatic plants in methane oxidation is not well understood. This study compared methane oxidation rates and bacteria abundance associated with different types of aquatic plants. The results showed that various plant types have different rates of methane oxidation, and high biomass of macrophytes is associated with reduced methane concentration in the water.

Summary: Coastal North Carolina has experienced 36 tropical cyclones in the past two decades, and three of them (Hurricanes Floyd-1999, Matthew-2016, and Florence-2018) caused significant floods. These floods led to catastrophic flooding, changes in water quality, fisheries habitat, and ecological conditions in the Albemarle-Pamlico Sound. The study found an increase in precipitation and flooding associated with tropical cyclones, which resulted in high storm-related freshwater discharge and nutrient loadings in the Neuse River Estuary, a major sub-estuary of the Albemarle-Pamlico Sound. The findings highlight the importance of event-scale discharge in carbon, nitrogen, and phosphorus loadings and the potential impacts on hydrology, water quality, and habitat conditions in estuarine and coastal waters.

Summary: Ponds and pondscapes play a crucial role in providing multiple benefits to both biodiversity and humans. However, they are often overlooked as Nature-based Solutions and there is a lack of knowledge on how to manage and restore them to maximize their potential in climate change resilience. To address this, it is important to generate and integrate various knowledge domains. Therefore, evidence-based guidance is needed to support the broader use of ponds.

Summary: We assessed the potential effects of Eucalyptus afforestation on water quality and macroinvertebrate assemblage. Nutrient concentrations, conductivity, and total dissolved solids showed positive responses to increasing afforestation, but the responses varied among seasons. Macroinvertebrate metrics showed negative and positive responses to afforestation, with densities of sensitive taxa decreasing and others increasing. The use of water quality parameters in combination with macroinvertebrates assemblage contributes to managing streams affected by afforestation.

Summary: With the retreat of glaciers, new ponds and lakes are formed, which become more productive as vegetation develops. Our study in West Greenland found that older lakes had higher nutrient concentrations and organic matter content, as well as higher biomass and richness of certain aquatic organisms. The food web in the older lakes was more complex, with a longer food chain and higher taxonomic diversity, suggesting a succession process following glacial retreat.

Summary: Ion-adsorption rare earth mining leads to high levels of nitrogen, multiple metals, and strong acidic mine drainage, which have unclear impacts on microbial assembly and ecological functions. We studied river sediments from China's largest ion-adsorption rare earth mine and found that bacterial community assembly was weakly influenced by spatial dispersion. Dispersal limitation and homogeneous selection were the dominant ecological processes, and bacterial alpha diversity decreased with pollution. Bacteria developed survival strategies to adapt to the extreme environment, sustaining species diversity and community stability.

Summary: Climate change is causing a northward shift of the boreal biome, but evidence of this shift is rare. Using satellite data, researchers found that tree cover change in the North American boreal biome has a strong north-south asymmetry, with no expansion at the northern boundary but a marked increase in the core range. However, tree cover declined at the southern boundary due to wildfires and logging, indicating a possible contraction of the biome that could lead to long-term carbon declines.

Summary: In this study, we analyze climate and carbon cycle indicators from marine sediments to investigate three major punctuated events during the late Paleocene-early Eocene warming. The results suggest that these events were triggered by climate-driven carbon cycle tipping points, and there is an intensifying coupling between the carbon cycle and climate during the long-term warming trend.

Summary: With the help of paleolimnology, the relationship between diatoms and environmental drivers in the Arctic lakes and ponds of Greenland was explored. The study found that climate and lake ontogeny were the main factors determining diatom communities. The species diversity declined towards the North, and diatoms were proven to be an excellent proxy for climate-mediated lake ecosystem change in the Arctic.

Summary: Theory suggests that long, negative feedback loops may destabilize food webs as complexity increases. However, the specific ways in which these feedbacks affect ecosystems' response to environmental change have received less attention. In this study, we describe five ways in which these feedbacks might lead to abrupt transitions and species losses. By combining models, we show that the likelihood of such transitions increases with the number of interacting species and the stability of network patterns. These findings raise questions about the stability of ecosystems under global environmental change.

Summary: Sustainable management of lakes requires addressing ecological, economic, and social challenges, with a focus on achieving ecological improvement in a co-beneficial context. In-lake restoration measures can bring rapid ecosystem responses, especially when combined with circular economy practices. However, lake restoration approaches need to be carefully assessed to ensure they effectively address lake-specific problems, are cost-effective, and promote valuable ecosystem services.
