Vegetation and tree growth analysis along altitudinal and latitudinal gradients in mixed-oak forests in mountain ecosystems of southern part of Korean penninsula
 ALTMAN, Jan
This study deals with the altitudinal and latitudinal changes in mountain-temperate vegetation of mixed-oak (Quercus mongolica) forests in southern part of Korean Penninsula. 108 forest relevés containing 283 vascular plant species were described at elevations from cca 400-1500 m in four mountains from Seorak Mts. (38°N, 1708 m a.s.l.) to Mt. Halla (33°N, 1950 m a.s.l.). Vascular plants were identified to species, and their total cover and covers of individual species in herb (< 1 m), shrub (1 - 5 m) and tree (> 5 m) layers estimated using Braun-Blanquet scale. Both classification and ordination methods (TWINSPAN cluster analysis and Dentrended and Canonical Correspondence Analyses) were used to analyze the variability in plant species composition and species-environment relationships. Redundancy analysis was used to analyze the variability in Raunkiaer life-form spectra in forest vegetation along the main gradients. Linear regressions were used to relate the species richness and diversity values to environmental variables. Finally, tree growth pattern in stem diameter (radial growth) was analyzed based on tree-ring data in major woody species co-occurring in two contrasting forest communities.
