Research Interests: carbon and nitrogen cycles in terrestrial ecosystems and global change

Summary
Background & Importance:
Forest ecosystems are critical regulators of global carbon sequestration and nutrient balance. Understanding coupled biogeochemical cycles – particularly carbon (C) and essential nutrients like nitrogen (N) and phosphorus (P) – is fundamental to predicting ecosystem responses to climate change, anthropogenic disturbances, and biodiversity loss. These interactions govern forest productivity, soil organic matter stabilization, and greenhouse gas fluxes, with cascading impacts on ecological stability and climate mitigation strategies.
Aim & Scope:
This Special Issue aims to synthesize cutting-edge research on mechanistic processes, drivers, and feedbacks within forest C-nutrient cycles. We seek contributions elucidating interactions across spatial (molecular to landscape) and temporal (diel to decadal) scales. The scope encompasses:
· C-nutrient stoichiometry and allocation dynamics
· Biotic-abiotic controls on mineralization and stabilization
· Impacts of global change (warming, drought, N deposition)
· Cross-system comparisons (natural vs. managed forests)
Suggested Themes:
· Litter decomposition and nutrient release
· Plant-soil-microbe interactions in the rhizosphere
· Soil organic matter formation and nutrient constraints
· Mycorrhizal mediation of C-nutrient trade-offs
· Disturbance legacies on cycling processes
· Novel methodologies for tracing coupled element fluxes
