“…The Keumsan LTER is located at a 360–430 m hillside elevation with slopes ranging from 12°–28°, and is influenced by habitat heterogeneity such as edaphic gaps (e.g. gravels or wet drainage sites) [50] . The most abundant species are Quercus serrata , Chamaecyparis obtusa , Styrax japonica , Acer pseudo-sieboldianum , Carpinus tschonoskii and Stewertia pseudo-camellia .…”

Numerous studies have demonstrated that tree survival is influenced by negative density dependence (NDD) and differences among species in shade tolerance could enhance coexistence via resource partitioning, but it is still unclear how NDD affects tree species with different shade-tolerance guilds at later life stages. In this study, we analyzed the spatial patterns for trees with dbh (diameter at breast height) ≥2 cm using the pair-correlation g(r) function to test for NDD in a temperate forest in South Korea after removing the effects of habitat heterogeneity. The analyses were implemented for the most abundant shade-tolerant (Chamaecyparis obtusa) and shade-intolerant (Quercus serrata) species. We found NDD existed for both species at later life stages. We also found Quercus serrata experienced greater NDD compared with Chamaecyparis obtusa. This study indicates that NDD regulates the two abundant tree species at later life stages and it is important to consider variation in species' shade tolerance in NDD study.

“…After collection, the leaf litter was airdried at room temperature for 9 days and 10 g of air-dried three dominant tree species (Q. serrata, C. laxiflora, C. cordata) was weighed to the nearest 0.01 g and placed in 30 cm £ 30 cm nylon net bag with a mesh size of 0.1 mm. In addition, mean annual leaf litter fall of these three tree species (Q. acutissima: 2323 kg ha ¡1 yr ¡1 ; C. laxiflora 442 kg ha ¡1 yr ¡1 ; C. cordata 157 kg ha ¡1 yr ¡1 ) in the Guemsan LTER site comprised 95% of total deciduous leaf litter fall (3055 kg ha ¡1 yr ¡1 ) fluxes (Kim et al 2013). Subsamples from the litter were also taken to determine the oven-dried mass after heating at 65 C for 48 h. The litterbags were randomly placed on the forest floor on 10 December 2004.…”

Litter decomposition represents a major contribution to the carbon and nutrient fluxes in forest ecosystems. Nutrient dynamics from decomposing leaf litter were measured for 3 years (1095 days) from three dominant tree species (Quercus serrata, Carpinus laxiflora, Carpinus cordata) in a broadleaved deciduous forest of the Geumsan (Mt.) Long-Term Ecological Research (LTER) site in Korea. Mass loss rates from decomposing leaf litter were significantly lower in the Q. serrata leaf litter (63.4% of the original mass) than in C. laxiflora (80.0%) and C. cordata (83.1%) leaf litter over 1095 days. There was a significant linear relationship between the remaining mass of leaf litter and the incubation months of litterbag (Q. serrata: r 2 D 0.96; C. laxiflora: r 2 D 0.96; C. cordata: r 2 D 0.95). Nitrogen and phosphorus concentrations (mg g ¡1 ) and remaining stocks (mg bag ¡1 ) from decomposing leaf litter were significantly lower in Q. serrata leaf litter than in C. laxiflora and C. cordata leaf litter during the study period. Calcium and magnesium concentration and remaining stocks of initial stage from decomposing litter were significantly higher in C. cordata leaf litter than in that of C. laxiflora and Q. serrata. However, potassium concentration and remaining stocks were not affected by the three leaf litter types.The results indicate that Carpinus spp. (C. laxiflora, C. cordata) leaf litter is a significant and easily decomposable source of nutrients among dominant tree species of a mixed broadleaved deciduous forest in the Geumsan LTER site.

“…The study was conducted in the Namhae National Forest located in Namhae-gun, Gyeongsangnam-do, southern Korea. The mean annual precipitation in this area is 1839 mm year −1 , and the mean annual temperature is 14.1 • C. The soil is a well-drained slightly dry or wet brown forest soil (Inceptisol, USDA soil taxonomy) originating from granite, with a loamy and acidic property of pH 4.53-4.63 [16]. Study plots were located in a Japanese cedar plantation and an adjacent natural Serrata oak stand (Figure 1).…”

This study compared carbon (C) and nitrogen (N) distribution at a stand level in an exotic Japanese cedar (Cryptomeria japonica D. Don) plantation and a natural Serrata oak (Quercus serrata Murray) stand growing under similar site conditions in South Korea. The aboveground biomass (stems, branches, and leaves) of 20 trees (10 of each species), the forest floor, and the mineral soils to a depth of 30 cm were sampled to determine C and N concentrations. Except in branches, C concentrations were significantly higher (p < 0.05) in the Japanese cedar plantation than in the Serrata oak stand, whereas N concentrations, except in the stem bark, were significantly lower in the Japanese cedar plantation. Reforestation with an exotic coniferous species significantly increased the C stocks in the aboveground biomass and the N stocks in the forest floor and mineral soils compared with a natural oak stand. The N stocks in the aboveground biomass were dependent on either the N concentrations or the C stocks in the tree components, whereas soil C and N stocks were negatively related to soil fertility parameters such as C/N ratio. Although it is uncertain which factors are responsible for the difference in aboveground C and soil N stocks following the establishment of Japanese cedar plantations on former natural Serrata oak stands, tree replacement may have an impact on C and N allocation within different forest compartments.
