Disentangling the Roles of Microbial Traits and Mineral Protection in Regulating Temperature Sensitivity of Soil Carbon Decomposition in Eroded and Depositional Agricultural Soils

open access: yesEarth's Future
The temperature sensitivity of soil organic carbon decomposition (Q10) governs the fate of soil carbon under global warming. Although erosion redistributes soil carbon at scales comparable to the terrestrial carbon sink, how erosion reshapes Q10 across ...

Spatiotemporal Dynamic Changes of Cropland in Rich and Coarse Sediment Areas of Middle Yellow River Basin Based on Multi-source Data Fusion Products

open access: yesShuitu Baochi Xuebao
[Objective] The rich and coarse sediment areas of middle Yellow River basin is a typical ecologically fragile area in China. Accurately quantifying the spatiotemporal dynamic changes of cropland in this region is crucial for evaluating regional food ...

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

The Economics of Soil Erosion: A Model of Farm Decision-Making [PDF]

open access: yes
Soil erosion is widely considered to be a serious threat to the long-term viability of agriculture in many parts of the world. The problem is particularly serious in certain developing countries.

Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Evaluation of Varnishes to Slow Down the Aging of Plasticized PVC

open access: yesJournal of Applied Polymer Science, EarlyView.
Varnish effectiveness in plasticized PVC strongly depends on both formulation and degradation state. A polyurethane varnish effectively limits color change and plasticizer loss in unaged PVC without phosphate plasticizers, whereas no protective effect is observed for phosphate‐containing PVC.

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

open access: yesJournal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Integrating machine learning, deep learning, and image analysis for seed species classification

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise The growing demand for wildflower seeds in ecological restoration requires reliable species identification, yet current market products often contain heterogeneous species. As seed identification is labor‐intensive and requires advanced botanical knowledge, we evaluated multiple segmentation and classification approaches to determine ...

Heterostructured Semiconductors for Advanced Chemical and Biochemical Sensors: From Gas Sensors to Electrolyte‐Gated Transistors

open access: yesAdvanced Physics Research, EarlyView.
Heterostructured semiconductors enable synergistic interactions between complementary materials, improving charge transport, analyte adsorption, and signal transduction in chemical and biochemical sensors. Their integration allows for high sensitivity, selectivity, stability, and low‐power operation across gas and liquid‐phase devices, while novel ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
