Summary: South Korean forests require hardwood tree species that can produce timber as the habitats of conifers dwindle due to global warming. Exotic yellow poplar has been planted to replace pine-dominated forests, but its growth varies among planting sites. Factors such as wind exposure, growing season temperature, latitude, soil phosphorus pentoxide content, low extreme temperature, and spring humidity were found to be the most important factors affecting yellow poplar growth in Korea.

Summary: From 1958 to 2020, Greenland experienced periods of cooling and warming, with a turning point in the mid-1990s. Overall, there has been no significant warming after around 2005, except in the north and northeast. The magnitude of warming increases gradually from south to north, with the northeastern coast experiencing the most intense warming. Autumn and winter are the seasons with the most intense warming, particularly in the northeast. The correlations of temperature with large-scale circulation indices weaken from southwestern to northeastern Greenland. The shift in the North Atlantic Oscillation (NAO) and Greenland Blocking Index (GBI) from positive to negative is critical to the sudden warming in Greenland since the mid-1990s.

Summary: Human activities have increased lead emissions in coastal seas, which have impacted the spatiotemporal distribution of lead. By studying lead and lead isotopes in a sediment core from the Central Yellow Sea Mud, it was found that lead concentrations varied along the core, with a significant anthropogenic disturbance since the late 1960s. The history of lead input experienced different stages, reflecting industrialization levels and lead contamination. The lead isotopic ratios are influenced by regional energy consumption patterns, with distinctive trends observed since 2000.

Summary: The study found that above-ground C cycling processes, A(sat)and ANPP(w), were highly resistant to increases in disturbance severity, while R(s) resistance declined as severity increased. Disturbance type had no effect on first-year resistance. Pre-disturbance aboveground woody biomass, and canopy rugosity were positive predictors of ANPP(w) resistance and, conversely, negatively related to R(s) resistance. Subcanopy A(sat) resistance was not related to pre-disturbance vegetation characteristics.

Summary: Pedotransfer functions (PTFs) provide point predictions of soil hydraulic properties from more readily measured soil characteristics, but uncertainties and biases in measurement methods, sampling distributions, and boundary conditions can limit accuracy, particularly in urban landscapes with altered hydraulic properties. The study developed PTFs to predict urban Kn, evaluated the role of bulk density and coarse fragments as explanatory variables, and compared predictive capabilities with measured hydraulic conductivity values from other studies of urban soil hydraulics. Results showed that additional factors like bulk density and coarse fragments did not significantly improve accuracy, possibly due to low correlation between Kn and bulk density and the exclusion of large voids during flow measurements.

Summary: This study used a meta-analysis approach to gather liana leaf optical spectra and canopy spectra data to investigate the impact of liana traits on the energy balance, light competition, and carbon cycle of tropical forests. The results showed that lianas have specific traits that make them more efficient at light interception, leading to modifications in forest energy balance and reductions in tree and ecosystem productivity while increasing liana productivity. This study provides new evidence on the impact of lianas on forest functioning and suggests implications for large-scale forest biogeochemical cycles.

Summary: Forests play a dominant role in the global carbon budget, but their ability to withstand and recover from disturbances under changing climate conditions is uncertain. This study used a combination of field experiments and modeling to investigate the response of a temperate deciduous forest to varying levels of disturbance and climate conditions. The results showed that both disturbance severity and climate had strong impacts on carbon fluxes, with a trade-off between resistance and resilience. The findings provide insights into the potential effects of future conditions on the functional stability of mature forests in the region.

Summary: A study finds discrepancies in historical estimates of global gross primary productivity (GPP) and respiration (RS), highlighting the uncertainty in the terrestrial carbon cycle. Estimating GPP based on RS measurements shows significantly higher GPP values compared to literature estimates, while global RS:GPP ratios are inconsistent with individual site calculations and model results. These discrepancies have implications for our understanding of carbon turnover times and terrestrial sensitivity to climate change.

Summary: The retrieval algorithms used for optical remote sensing satellite data to estimate Earth's geophysical properties have specific requirements for spatial resolution, temporal revisit, spectral range and resolution, and instrument signal-to-noise ratio (SNR) performance. Different scientific fields may have varying sensitivity to mission architecture choices that affect spectral, spatial, or temporal resolutions and spectrometer SNR. The interplay between spatial resolution, temporal revisit, and SNR can be quantitatively assessed for imaging spectroscopy missions and used to identify key components of algorithm performance and mission observing criteria.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
