    Characterizing fine-scale spatiotemporal variations in canopy litterfall and fine root dynamics in cool temperate forest ecosystems by Mark Bryan Carayugan, Ji Young An, Byung Bae Park

    Published 2025-06-01
    “…This study combined up to four years of field measurements (2–4 years for litterfall, 1 year for fine root stocks, and 2 years for fine root production and mortality) from twelve 0.02–0.09-ha stands in Gwangneung Experimental Forest to investigate the relationships between litter and fine root variability and stand topographic, structural, and edaphic features. Topography emerged as a key driver of variation within stands, significantly influencing total litterfall (βstd.= −0.568 for elevation; βstd.= −0.597 for slope), leaf litterfall (βstd.= −0.722 for elevation), total fine root biomass (βstd. = −0.863 for slope), and < 1mm-sized root biomass (βstd.= −0.618 for slope). …”
