| Research Abstract |
Analyses of nutrient dynamics in tree leaves and soils indicated characteristic patterns of soil-nutrient limit to tree growth on Mt. Fuji. In the forests on scoria soils, severity of the nutrient (N and P) limit increased with altitude, and that of P-limit changed more than that of N-limit for broad-leaved species. In pine forests on the lava flows, an evergreen broad-leaved tree species dominating in the sub-canopy of the forest had more conservative and efficient use of N and P than a co-occurring deciduous broad-leaved species. This indicated an advantage of the evergreen habit in nutrient-poor habitats.
