Extreme heat events have increased markedly over recent decades globally, with potentially severe impacts on soil carbon (C) cycling. Here, we conducted a mechanistic study to assess the impact of a single 3‐day extreme heat event (30°C, 40°C, 50°C) on C cycling in an arable soil in North Wales, exploring subsequent 200‐day potential legacy effects and shifts in microbial community structure. Soils exposed to 30°C or 40°C did...

The accumulation of microbial‐derived organic carbon in soils during long‐term vegetation succession represents a key pathway for long‐term soil carbon stabilization. Yet, the role of soil microfauna in regulating microbial carbon dynamics remains poorly understood, particularly across divergent successional trajectories (primary vs. secondary successional gradients). We investigated nematode‐microbe interactions influencing c...
