“…They found 5 939 kg⋅ha -1 ⋅a -1 litter under Acacia mangium plantation in South Sumatra, Indonesia. Litter fall found here under the natural forest at Sitapahar was comparable to Liao et al (2006), who reported litter fall ranging from 6 980 to 9 130 kg⋅ha -1 ⋅a -1 , in coral reef tropical forest in southern Taiwan.…”

Litter fall and its effect on forest soil properties at each decomposition stages were investigated in tropical monsoon climatic conditions of three plantations (7-year acacia plantation, 15-year acacia plantation and 18-year mixed plantation) and one natural forest (Sitapahar forest) from Chittagong hilly region of Bangladesh. Results showed that total accumulation of organic matter increased with plantation age, accompanying with a decrease of annual accumulation rate. Within the same vegetation type, the organic accumulation of both fresh and partially decomposed litter with humus varied significantly (p≤0.05) on hill positions, being highest on bottom slope and decreased gradually towards hilltop in the forest. Reverse trend in accumulation of soil organic matters was shown in 15-year Acacia auriculiformis plantation, from where fuel wood collected. In 7-and 15-year acacia and 18-year mixed broadleaved plantations, rates of total organic matter production consisting of fresh, partially and completely decomposed litter as well as incorporated organic matter in soil were 2554.31, 705.79 and 1028.01 kg⋅ha -1 ⋅a -1 , respectively, and the corresponding contribution from fresh litter were 38.23, 19.40 and 30.48 kg⋅ha -1 ⋅a -1 , respectively. In the three plantations and the natural forest, on an average fresh litter constituted 32.45%, partially decomposed litter with humus 13.50% and incorporated organic matter in soil 54.56% of the total organic matter production with mean litter thickness of 0.90 cm. Soil acidity increased with the increase of decomposition stage of organic matter.

“…This reserve is underlain by Miocene rocks and featured by elevated coral reefs (Liao et al 2006;Wang et al 2004). The underlying formation is Hengchun limestone that is an organic reef and composed of remains of various organisms, such as corals, foraminifers, mollusks and calcareous algae (Liao et al 2006). The annual mean temperature and precipitation is 25°C and 1,964 mm during 1997-2002 according to the database of the nearby Hengchun Weather Station.…”

Understanding processes underlying spatial distribution of tree species is fundamental to studying species coexistence and diversity. This study modeled point patterns of tree distribution, expressed by Cartesian coordinates of individual trees within a mapped forest stand, for the purpose of identifying processes that may generate spatial patterns of tree communities. We used four primary point pattern processes (homogeneous Poisson process, inhomogeneous Poisson process, homogeneous Thomas process, and inhomogeneous Thomas process) to model tree distribution in two stem-mapped forests in Taiwan, Republic of China. These four models simulate spatial processes of habitat association and seed dispersal, allowing us to evaluate the potential contribution of habitat heterogeneity and dispersal limitation to the formation of spatial patterns of tree species. The results showed that the inhomogeneous Thomas process was the best fit model and described most of the species studied, suggesting that spatial patterns of tree species might be formed by the joint effects of habitat associations and dispersal limitation. The homogeneous Thomas process that models the effect of dispersal limitation was the second best model. We also found that the best fit models could be predicted by species attributes, including species abundance and dispersal mode. The significant traits, however, differed between the two study plots and demonstrated site-specific patterns. This study indicated that the interactive operation of niche-based (habitat heterogeneity) and neutral-based (dispersal limitation) may be important in generating spatial patterns of tree species in forest communities.

“…Among these ecosystems, tropical and subtropical forests are important vegetation types on the Earth, therefore a large number of studies have recently been conducted in these forests in order to understand C and N cycling through investigations of litter decomposition (Wen et al 1989;Wu et al 1990;Wu 1991;Zhao et al 1991;Didham 1998;Gurvich et al 2003;Cleveland et al 2006;Liao et al 2006;Zou et al 2006;Li et al 2007;Kaspari et al 2008).…”

A long-term (20 months) bulk litter decomposition experiment was conducted in a subtropical plantation in southern China in order to test the hypothesis that stable isotope discrimination occurs during litter decomposition and that litter decomposition increases concentrations of nutrients and organic matter in soil. This was achieved by a litter bag technique. Carbon (C), nitrogen (N) and phosphorus (P) concentrations in the remaining litter as well as d 13 C and d 15 N during the experimental period were measured. Meanwhile, organic C, alkali-soluble N and available P concentrations were determined in the soils beneath litter bags and in the soils at the control plots. The dry mass remaining (as % of the initial mass) during litter decomposition exponentially declined (y = 0.9362 e -0.0365x , R 2 = 0.93, P \ 0.0001), but total C in the remaining litter did not decrease significantly with decomposition process during a 20-month period. By comparison, total N in the remaining litter significantly increased from 5.8 ± Statistically, litter decomposition has little impact on concentrations of soil organic C and alkali-soluble N and available P in the top soil. This indicates that nutrient return to the topsoil through litter decomposition is limited and that C cycling decoupled from N cycling during decomposition in this subtropical plantation in southern China.
