The Spatial Structure of Competitive Interactions: Evidence From Public Procurement Networks in Quebec

How can functional procurement markets be delineated from observed bidding behavior? Using bid-level data from Quebec’s municipal paving sector (2012–2019), we construct a geographical bidder overlap (GBO) index measuring supply-side substitutability between postal codes. Gravity...

Land-use legacy shapes soil- and root-associated microbial communities, modifies nutrient cycling, and influences vine physiology

Soil microbial communities are central to ecosystem functioning, influencing organic matter decomposition, nutrient cycling, and plant nutrition. Plant microbiomes, including mycorrhizal symbioses, play a key role in plant nutrient uptake and are strongly influenced by soil manag...

Accurate MAG reconstruction from a complex soil microbiome through combined short- and HiFi long-reads metagenomics

Abstract Background Advances in high-fidelity long-read (HiFi-LR) sequencing technologies have opened new opportunities to explore the microbial genomic diversity of complex environments, such as soils. While short-read (SR) sequencing has enabled broad insights at the gene level...

Pure Mycelium Sheets from Edible Mushrooms for Sustainable Packaging: A Comparative Assessment of Glycerol and ZnONPs Treatment

Increasingly, mycelium-based biomaterials are being investigated as sustainable alternatives to conventional packaging materials, but their inherent brittleness limits their practical application. The present study investigated the properties of pure mycelium sheets sourced from...

Seasonal dependence of temperate forest soil respiration to soil temperature and water content clarified through data-driven modeling

Soil respiration is commonly modelled as a function of soil temperature and soil moisture, without explicitly accounting for seasonal effects. We have therefore developed a data-driven model that integrates interactions among soil temperature, soil moisture, and seasonality. This...
