Microbially Mediated Soil Carbon Sequestration Under Long‐Term Increased Snow Cover: Divergent Mechanisms Between Topsoil and Subsoil in a Temperate Grassland

open access: yesEarth's Future, Volume 14, Issue 10, October 2026.
Abstract Climate‐driven changes in winter snow cover alter soil microclimate and hydrology, affecting soil organic carbon (SOC) dynamics, whereas the mechanisms by which long‐term deepened snow influences SOC sequestration across soil profiles remain unclear.

Inferring Adaptation at Community Composition Level From the Relationship Between Succession Rate and Global Change Intensity

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
A 10‐year nitrogen addition experiment in Eurasian steppe reveals that plant and microbial community succession rates first increase then decrease with rising N intensity, indicating an adaptive threshold. Deterministic processes driven by soil physicochemical changes dominate this response, with management strategies modulating adaptation via ...

Microfoundations of Adaptive Decision‐Making Capability: How Chief Supply Chain Officers Convert Technology‐Enabled Visibility Into Coordinated Action

open access: yesJournal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT Supply chain leaders increasingly operate with extensive technology‐enabled visibility, yet many firms still struggle to convert shared signals into timely, coordinated action. We frame this tension as the visibility‐to‐action problem in supply chain management (SCM): executives observe more than they can process and often fail to route ...
