Summary: This study proposed a photosynthetically active radiation (PAR)-regulated dynamic sigma(max) (PAR-LUE) model for estimating gross primary productivity (GPP). Compared to existing LUE models, the PAR-LUE model can accurately estimate GPP and reduce estimation errors. The validation results showed that the PAR-LUE model had higher accuracy in GPP estimation compared to other LUE models, and effectively alleviated the underestimation of high GPP. In summary, the PAR-sigma(max) model provides a method for estimating GPP using spatiotemporal dynamic sigma(max), which reduces the uncertainty in GPP estimation and offers a new option for optimizing sigma(max) in the LUE model.

Summary: In this study, a phenology-based strategy was used to estimate the parameter e(0) and its optimal photosynthetic responses in different phenological stages. The results showed that the phenology-based GPP(phe-based) tracked the seasonal dynamics and inter-annual variation of GPP(EC) well, especially in forest, cropland, and wetland ecosystems. Additionally, the phenology-based e(0) was found to be more appropriate for GPP estimation in herbaceous plants compared to the VPM-based GPP(VPM).

Summary: Drought, caused by global warming, is becoming more frequent and is a main factor leading to the loss of terrestrial ecosystems gross primary productivity (GPP). Sun-induced chlorophyll fluorescence (SIF) has been found to be a more accurate and sensitive indicator of vegetation drought and drought-induced GPP variations compared to normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI). SIF is an effective tool for timely detection of regional drought and ecosystem management.

Summary: Solar-induced chlorophyll fluorescence (SIF) is a reliable indicator of vegetation gross primary productivity (GPP), but the ratio of photosynthetic light use efficiency (LUE) to total SIF quantum yield (SIFyield) can introduce uncertainty in SIF-GPP models. This study found that LUE decreases as photosynthetically active radiation (PAR) increases, impacting the accuracy of GPP estimation models. By integrating the influence of PAR on LUE, the SIF-GPP model for maize showed improved accuracy and reduced error in GPP estimation.

Summary: This study reveals significant spatial variations in the GPP/SIF ratio in ecosystems across the globe, which are strongly modulated by climate variables. There is a consistent decrease in GPP/SIF from cold-and-wet to hot-and-dry climates. Empirical modeling using machine learning shows promise in improving ecosystem production modeling and quantifying uncertainty in global terrestrial biosphere models, highlighting the need for targeted field and experimental studies to better understand observed patterns.

Summary: This study investigated the consistencies between a photosynthetic activity index (SIF) and a traditional vegetation index (NDVI) among different land-cover types and in different seasons. The results showed that while vegetation cover and photosynthesis were decreasing, SIF performed better than NDVI in monitoring gross primary production (GPP) and grain yields in different land-cover types.

Summary: Limited information is available on the relationship between solar-induced chlorophyll fluorescence (SIF) and gross primary production (GPP) in C4 cropping systems. This study compared the SIF-GPP relationships of corn and miscanthus and found significant differences, mainly attributed to leaf physiology. Miscanthus exhibited a decline in SIF under high light, temperature, and water vapor deficit conditions, leading to a weakened SIF-GPP relationship, while corn showed a stronger SIF-GPP relationship due to higher leaf photosynthesis.

Summary: This study investigates the lagged and cumulative effects of drought on global grassland gross primary production (GPP) using remote sensing data and climate indices. The results show that the majority of grasslands globally exhibit lagged responses to drought, with a typical lag time of one month. Cumulative effects of drought on grassland GPP are widespread, and relatively arid areas show stronger cumulative effects. The study highlights the importance of considering the cumulative effect of drought on grassland productivity, which surpasses the lagged effect.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
