Our results showed that natural mangroves had the highest SOC levels, particularly in surface soils, confirming their higher carbon sequestration potential. Restored mangroves exhibited incomplete SOC recovery, with levels closer to tidal flats than to natural mangroves. Tidal flats displayed minimal SOC storage, with little variation across soil depths. Surface soils were identified as the primary carbon storage zone in all ecosystems. Distinct drivers of SOC were identified for three different types of ecosystems: species composition, total nitrogen (TN), total phosphorus (TP), and salinity in natural mangroves; species composition and TN in restored mangroves; and TN and TP in tidal flats.

This study proposed an innovative approach in which RFRH was integrated with chopped straw-soil crust instead of plastic film. Runoff observations and alfalfa production experiments were carried out using a split-plot design to investigate the impact of varying chopped straw lengths (2 cm and 10 cm) and application rates (0 (R<sub>0</sub>), 3 (R<sub>3</sub>), 6 (R<sub>6</sub>), and 9 (R<sub>9</sub>) t ha<sup>−1</sup>) on runoff coefficient, soil water storage, temperature, fodder yield, and crop water productivity (WP<sub>C</sub>).

The reduction in temperature within the furrow profile for those treatments was 0.4–1.0°C, 0.8–1.3°C, and 1.1–2.0°C, respectively. The increase in fodder yield for those treatments ranged from 11.3 % to 34.0 %, 31.2 %-62.9 %, and 7.9 %-47.7 %, respectively, while the enhancement in WP<sub>C</sub> was 1.3–14.8, 5.1–27.9, and 2.0–20.7 kg ha<sup>−1</sup> mm<sup>−1</sup>.

Dynamic monitoring of leaf Cp, CBC, and LAI can provide valuable insights for agricultural management, such as analyzing the impact of environment stress factors on potato growth throughout its lifecycle. Currently, the most commonly used method for estimating crop parameters is the vegetation spectral feature-statistical regression approach. However, leaf Cp and CBC estimation are greatly influenced by water absorptions, as they exhibited overlapping spectral features in the short-wave infrared (SWIR) region. Consequently, the accuracy of protein estimation using traditional vegetation spectral feature-statistical regression methods is limited. This study aims to propose a comprehensive approach called PCPNet (Potato Canopy and Leaf Parameter Network), which could jointly estimate potato canopy and leaf parameters including Cp, CBC, and LAI. The performance of the PCPNet was compared with traditional spectral feature-statistical regression methods in estimating Cp, CBC and LAI. A simulated dataset for pre-training was generated using the PROSPECT-PRO and SAIL radiative transfer models to represent various complex scenarios encountered in real-world potato cultivation practices. The designed PCPNet was initially pre-trained based on this simulated dataset and then re-trained using ground-based measurements from five potato growing seasons across two distinct regions in China through transfer learning techniques. The validation of potato canopy and leaf parameters was conducted based on the estimations provided by the PCPNet model, while assessing their accuracy. This study yields the following results: (1) The PCPNet-based deep learning model demonstrated markedly superior accuracy in estimating potato Cp, CBC, and LAI compared to traditional machine learning models. (2) The deep learning model pretrained with transfer learning exhibited greater estimation accuracy than the deep learning model trained from scratch.

This study explores the potential of the buccal (oral) microbiome as a diagnostic indicator for SARA, hypothesizing an interaction with the rumen microbiome. The study involved 47 dairy goats, including 11 on a control diet and 36 on high-concentrate diets with increasing rumen-degradable starch. Animals were grouped based on dietary exposure and ruminal pH: Control, Low-RDS Tolerance/SARA (LRDST/LRDSS), and High-RDS Tolerance/SARA (HRDST/HRDSS). Transcriptomics of rumen epithelium showed heightened inflammatory pathway gene expression in SARA-susceptible goats compared to controls and tolerant groups. Alpha diversity of ruminal bacteria showed lower Shannon diversity in HRDSS goats compared to HRDST whereas buccal bacteria displayed significantly lower Chao1 diversity in LRDSS goats compared to HRDST. Beta diversity analyses revealed distinct patterns between SARA-affected goats and healthy controls in both ruminal and buccal microbiomes. Prevotellaceae_UCG-003 emerged as a candidate biomarker, with reduced abundance in SARA-susceptible goats in both rumen and buccal samples. Machine learning classifiers achieved high accuracy in distinguishing SARA-susceptible goats using this genus (rumen AUC = 0.807; buccal AUC = 0.779). Source tracking analysis illustrated diminished cross-population of bacteria from the buccal to rumen (2.86% to 0.25%) and vice versa (8.59% to 1.17%), signifying compromised microbial interchange in SARA-affected goats. A microbiota transplant experiment verified SARA microbiota's ability to induce pH decline, escalate inflammation-related gene expression (MAPK10, IL17B, FOSB, SPP1), disrupt microbial transfer, and reduce Prevotellaceae_UCG-003 in recipients. Our findings highlight SARA’s dual impact on ruminal and buccal microbiota, exacerbating epithelial inflammation gene expression.
