Summary: Shrubs in Inner Mongolian grassland increased in abundance with increasing climatic aridity and grazing intensity. The effects of these factors on the sexual reproduction of shrubs remained unclear. This study focused on Caragana microphylla and found that climatic aridity decreased seed quantity and seed vigor but increased the sapling establishment rate. Grazing reduced seed production, sapling establishment, and population growth rates. The combined effects of climatic aridity and grazing had negative effects on the sexual reproduction of Caragana shrubs, suggesting that clonal reproduction might be important for understanding shrub encroachment in grasslands.

Summary: The study indicates that the distribution of fine roots along the soil profile promotes fertile islands extending from the surface to deep soils. Soil texture affects fine root distribution, which consequently modulates the intensity of fertile islands.

Summary: This study examines the potential impacts of spatial heterogeneity on surface urban heat island (SUHIs) through a case study of Greater London and Seoul. Results indicate that measures of heterogeneity in green space ratio, building coverage ratio, and canyon H/W ratio significantly impact land surface temperatures.

Summary: The study revealed spatial heterogeneity of soil biotic and abiotic resources due to fertile islands in deserts. Nutrient and decomposer enrichment was observed under mid-canopies, while oligotrophs and nitrate reducers were enriched in bare soil. Soil properties showed less spatial heterogeneity compared to bacterial communities.

Summary: Investigating the biomass dynamic variations of the Caragana korshinskii shrub in the arid desert area of Ningxia, China, this study developed a model to predict its growth and accurately estimate its carbon storage. The NSUR method of the NLS equations system outperformed other methods and was efficient for predicting AGB growth. This research has significant implications for natural resource management and carbon neutralization efforts.

Summary: This study investigated the spatial heterogeneity and driving factors of soil total nitrogen in shrubland at the landscape scale in eastern Yanchi County of Ningxia Hui Autonomous. The results showed that soil water content and organic carbon content primarily drove the formation of soil total nitrogen spatial heterogeneity in the shrubland, indicating the impact of shrub encroachment on soil attributes.

Summary: With the increase of global warming, the uncertainty of ecosystem evolution in drylands has also increased. The objective of this study was to test whether the desertification process of tamarisk shrubland was intensified by comparing fertile island effects and soil ecological stoichiometry characteristics at different time periods. The results showed that the fertile island effects disappeared completely in the shrub duneland stage, and the desertification process accelerated in this stage but showed no obvious progress in the shrubland stage. The loss of soil carbon may contribute to global warming.

Summary: This study quantified the mechanical responses of different minerals in layered rocks using nanoindentation tests and high-resolution scanning electron microscopy. The results showed that the mechanical properties of quartz and dolomite varied between different layers, with quartz displaying elastic-dominated deformations in the sandstone layer and medium-plastic deformations in the mudstone layer.

Summary: The topography influences the spatial variation of soil thickness and soil moisture on karst slopes. Analyzing the spatial heterogeneity of soil moisture on hillslopes is important for maintaining ecosystem stability. By utilizing geostatistical methods and GIS technology, the spatial variability and distribution pattern of soil moisture and its influencing factors were analyzed on a typical karst shrub-grass hillslope.

Summary: Spatial segmentation is crucial in mass spectrometry imaging (MSI) for biochemical analysis. However, commonly used unsupervised segmentation methods may not produce accurate results due to the high dimensionality and low signal-to-noise ratio of the MSI data. This study proposes an interactive segmentation strategy called iSegMSI, which incorporates prior information to fine-tune the segmentation results, leading to improved MSI segmentations.

Summary: Spatial transcriptomics technology enables topographical gene expression profiling of tumor tissues, but cell type deconvolution in tumor ST data remains challenging. We develop SpaCET, a method that accurately infers cell identities from tumor ST data and reveals intercellular interactions at the tumor-immune interface.
