Abstract Soil microbial biomass (MB) generally exhibits a narrower C:N than soil organic matter (SOM), creating a stoichiometric discrepancy hypothesized to be reconciled in part by C‐ and N‐acquiring enzyme activities. We used soils from an at‐equilibrium long‐term experiment to evaluate the degree to which MB C:N plasticity and enzyme activities ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

ABSTRACT The article investigates how Indigenous labour interacts with powerful sediment movements and flooding cycles in 23 riverine communities in Bolivian Amazonia. These interactions, we argue, transcend the binary between human labour and biophysical processes in shaping flux urban political ecologies, landscapes and human settlements that ...

Fracture mechanism of acid fracturing of sandstones gangue layer in fully mechanized mining face
Taking the coal seam sandstone intercalated gangue layer at 112201 large mining height face in Xiaobaodang Mining Area of Yulin as the research object, the special rock acid fracturing method based on trace CO2 hydrate is proposed through the comprehensive experimental analysis of the physical, mechanical, and chemical properties of the sandstone in ...

ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...
