Intraspecific variation in root economics space by branching order of fine roots across a shallow soil depth gradient in Cryptomeria japonica forest

Key Points

• Intraspecific variation in root economics space is evident across different branching orders of fine roots, indicating ecological strategies in Cryptomeria japonica.
• Analysis shows that variations in branching order influence root function significantly within a shallow soil depth gradient.
• Observational analysis across varying soil depths assesses the economics of fine roots and their branching orders in Cryptomeria japonica forests.
• Highlights the importance of understanding root economics for forest management and conservation efforts, particularly in adapting to environmental changes.
