Effects of microclimate, litter type, and mesh size on leaf litter decomposition along an elevation gradient in the Wuyi Mountains, China

Litter decomposition rates vary significantly along elevation gradients, influenced by microclimate conditions and litter type. The study found that leaf litter from Castanopsis carlesii decomposed faster than Pinus taiwanensis at lower elevations (evergreen broadleaf forest, coniferous forest, and dwarf forest), where warm and humid conditions favor decomposer activity. However, decomposition rates were similar for both species in alpine meadows, suggesting microclimate plays a crucial role. Restricting access to detritivores via mesh bags also slowed decomposition, highlighting the importance of soil fauna in litter breakdown. These findings underscore how temperature, moisture, and ecosystem structure interact to regulate decomposition processes in UNESCO World Heritage Sites like Mount Wuyi.
