Summary: This study revealed the significant impact of revegetation age and soil depth on soil carbon and nitrogen levels, demonstrating that 15-year-old Caragana korshinskii plantations show the highest accumulation of soil carbon and nitrogen. Additionally, the soil at 100-200 cm depth contains a substantial portion of the total cumulative stocks of SOC and TN, suggesting the importance of considering soil depth in vegetation restoration strategies.

Summary: In this study, EDA pretreatment was found to be more effective in promoting the digestibility of Caragana korshinskii Kom. compared to hydrothermal and NaOH pretreatment. The EDA treatment showed good delignification and de-crystallization effects, leading to high cellulose enzymatic conversion efficiency. Using EDA-pretreated CKK as a substrate for bacterial cellulose production showed that lower nutrient levels in the enzymatic hydrolysate medium could hinder fermentation performance, but additional nutrients improved BC production efficiency. Under optimized conditions, the BC yield reached 4.6 g/L.

Summary: Global nitrogen deposition has broad impacts on soil microorganisms, but how they respond to elevated N deposition, especially in tropical forest ecosystems, remains unclear. In this study, a field experiment was conducted to investigate the responses of microbial composition, biomass, and community structure with long-term N addition at different stages of tropical forest succession. The results showed that N addition significantly changed microbial community structure, and N treatment contributed more variance to the fungal community than to the bacterial community. These findings suggest that soil microbial community structure is more sensitive to N addition and can be severely altered during forest succession or with the increase in N input.

Summary: Resprouting plants exhibit changes in stem hydraulic structure and anatomical traits with increasing age, transitioning from an acquisitive strategy to a conservative strategy. These changes are characterized by decreases in maximum stem hydraulic conductivity and water potential at 50% loss of hydraulic conductivity, as well as increases in vessel implosion resistance and wood density.

Summary: Drought stress poses a severe threat to plant development and survival. The transcription factor CkREV plays a significant role in regulating the development of xylem vessels in leaf veins in response to drought stress. It enhances plant drought tolerance by controlling the expression of related genes involved in auxin polar transport, vessel differentiation, and cell wall deposition.

Summary: Stable isotopes are widely used to identify root water uptake by classifying potential water sources and evaluating their contributions. However, the estimated contributions of endmembers are usually based on soil water isotopes alone. Available soil water and root distributions are important factors that are often overlooked in water source attribution.

Summary: This study presents an attempt to automatically detect locomotor play behaviour in young pigs from video using deep learning methods. The deep learning classifier outperformed other methods and achieved high recall, precision, and specificity. The combination of a less computational heavy method with deep learning reduced the computational requirements and accurately detected locomotor play behaviour.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: This paper presents an integrated Geoarchaeological approach to studying the landscape change and socio-environmental interaction around ancient Abdera. The study uses a combination of remote sensing, geomorphological mapping, sedimentary coring, and radiocarbon dating to reconstruct the palaeogeographic evolution of the area. The results challenge previous narratives about the rise and decline of Abdera and provide new insights into the role of historical and environmental factors. It also introduces evidence of submerged Neolithic landscapes and the impact of anthropogenic forcing on the sedimentary systems.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.

Summary: There is a lack of research on the potential of tropical soils in the Brazilian Atlantic Forest biome to store carbon. This study aimed to determine the soil carbon stocks at different depths, describe their temporal variability, and identify the main drivers that influence their variations. The results showed significant spatial and seasonal variability in soil carbon stocks, with a high accumulation in December and a low accumulation in August. The study also found that litterfall, throughfall, tree sizes, and soil moisture were important factors affecting the distribution of soil carbon.
