Monitoring habitat conservation status and assessing biodiversity: The Dehesa case

This paper proposes an operational, reproducible framework that integrates probabilistic field sampling with Earth observation data (Sentinel-2 and LiDAR) to monitor and assess the conservation status and biodiversity of heterogeneous agroforestry systems like the Mediterranean Dehesa, offering statistically rigorous indicators for carbon, flora, and fauna while ensuring transferability to other landscapes.

Evaluation of the Impact of Different Land Use Types on Shallow Groundwater and Discussion on Water Chemistry Genesis A Case Study of the Middle Reach of the Beijiaolai River

This study evaluates the impact of different land use types on shallow groundwater in the middle reach of the Beijiaolai River, revealing that a dual driving mechanism of natural rock weathering and anthropogenic inputs (specifically domestic sewage and agricultural non-point sources) shapes the hydrochemical characteristics, with construction land showing higher mineralization and fluoride enrichment primarily driven by calcium fluoride dissolution.

The Effect of Gas Migration From Deep Geological Formations Into Mine Workings During the Evolution of Mining-Induced Seismicity

This paper proposes and models a mechanism linking the intensification of gas emissions in mining areas, such as Kuzbass, to the downward migration of critically stressed crustal states and associated seismicity, which creates fractures that allow methane to migrate from deep geological formations (up to 5–6 km) into mine workings.

Population Weighted Ambient PM2.5 and O3 Concentrations in China from 2015 to 2024

This study reveals that from 2015 to 2024, China experienced a significant 41.1% decline in population-weighted PM2.5 concentrations alongside a 25.6% increase in population-weighted O3 levels, highlighting a critical divergence in air quality trends that underscores the necessity of using population-weighted metrics alongside geographic averages for accurate air quality assessment.

Estuarine mixing governs spatiotemporal partitioning of potentially toxic elements between coastal waters and sediments in the western Indian Ocean

This study demonstrates that estuarine mixing, particularly salinity gradients, is the dominant driver governing the spatiotemporal distribution of ten potentially toxic elements between coastal waters and sediments along the Kenyan coast, highlighting the necessity of paired water-sediment monitoring stratified by mixing regimes rather than relying on single-season water surveys.

Enrichment of toxic elements and potential ecological risks from asbestos-bearing mine wastes

This pilot study demonstrates that asbestos-bearing mine wastes in developing countries act as significant reservoirs of toxic elements like Mg, Ni, and Cu, posing substantial ecological risks and potential human health hazards, particularly from anthophyllite and chrysotile wastes, thereby validating the use of contamination indices as an effective framework for future environmental monitoring and remediation.

Measuring carrying capacity of steel material from the perspective of closed-loop supply chain

This paper extends carrying capacity theory to the micro-enterprise level within closed-loop supply chains by developing a quantitative framework that identifies upstream losses as key constraints and demonstrates that enhancing scrap recycling rates can significantly reduce primary iron ore demand, as validated by data from major Chinese steel producers.

Prevailing European light regimes are mismatched with conditions for high plant diversity

By integrating extensive vegetation data with Earth observation, this study reveals that contemporary European landscapes predominantly feature darker, more homogeneous light regimes that significantly mismatch the open, heterogeneous conditions required for high plant diversity, occurring in only 5.4–8.3% of natural and semi-natural areas.
