“…The mean annual temperature is 23.6°C, and annual precipitation is 1,677.1 mm at ca. 100 m elevation, with a distinct wet season from May to October and a dry season from November to April (Zang et al 2005). Tropical cloud forest in BNR is primary old growth forest, and is mainly distributed on the mountaintops of SLDM, FTLM and YJSM at elevations over 1,250 m with ca.…”

Specific leaf area (SLA) is a key functional trait reflecting the trade-off between resource capture and conservation, and has been identified as playing an important role in plant community assembly. Mechanistic models of community assembly state that the assemblage of species in a local community is controlled by environment filters operating on functional traits. We measured within- and among-species variation of SLA, and environmental conditions in a tropical cloud forest to explore how variation in this functional trait contributes to community assembly. SLA variation at the species level was also decomposed into alpha (within assemblage variation), and beta (across assemblage variation) values. SLA decreased with increasing solar irradiance (approximated using plant height) within the three study sites, and differed among the three sites both for within- and among-species comparisons. Mean plot SLA, accounting for both within and among species across the three sites, increased significantly in relation to air temperature but not local photosynthetic photon flux density and soil total phosphorus. Alpha SLA decreased with increasing solar irradiance within the three sites and beta SLA differed among the three sites. Our results clearly demonstrate that light and air temperature are key environmental factors involved in organizing plant species within and among communities in tropical cloud forests. The strong relationship between both intra- and interspecific variation in SLA and environmental conditions strongly confirms the role of trait variation in the assembly of plant species in tropical cloud forest communities via environment filtering related to light availability and air temperature.

“…The more litter on the ground, the stronger the water holding capability. The different species composition and structure between gaps and under canopy cause the different composition of forest floor litter in gaps and under canopy (Zang et al, 1999(Zang et al, , 2002Zhu and Li, 2002;Bianba, 2004). Previous studies showed that the thickness, amount, water content of litter under canopy were significantly higher than those in gaps (p<0.01).…”

“…Due to the difference of dominance and characteristics of different species, species composition and diversity index are different between gaps and under canopy forest (Zang et al, 1999(Zang et al, , 2002Geng et al, 2002). The overstory density is higher in gaps than those under canopy.…”

The species composition and diversities, and soil properties under canopy gaps in broad-leaved Pinus koraiensis forests were studied in the Changbai Mountains. The results indicated that the species composition and diversities in gap were different from those under canopy. The Shannon-Wiener index, evenness index, and abundance index in gap were higher than those under canopy in the seedling layer, while the community dominance in the seedling layer increased in closed canopy. The physicochemical properties of soil changed with the change of space and resource availability in gaps. The thickness, standing crop, and water holding capacity of the litter layer under canopy were significantly (p<0.01) higher than those in gap. The content of total nitrogen and total potassium of litter in gap were 10.47% and 20.73% higher than those under canopy, however, the content of total phosphorus and organic carbon under canopy were 15.23% and 12.66% more than those under canopy. The water content of 0-10 cm and 10-20 cm of soil layer in gap were 17.65% and 16.17% more than those under canopy. The soil buck density of 0-10 cm were slightly higher under canopy than that in gaps, but there was no significant difference in the soil buck density of the 10-20 cm soil layer. The soil pH values were 5.80 and 5.85 in gap and under canopy, respectively, and were not significantly different. The content of soil organic matter, total nitrogen, and total potassium in gap were 12.85%, 7.67%, and 2.38% higher than those under canopy. The content of NH 4 + -N, available phosphorus, available potassium, and total phosphorus in soil under canopy were 13.33%, 20.04%, 16.52%, and 4.30% higher than those in gap.

“…Despite a few studies in Indian sub-tropical region (Barik et al 1992), southern tropics of India (Chandrashekara and Ramakrishnan 1993) and China (Zang and Wang 2002;Li et al 2005;Zang et al 2005) and temperate forests of Nepal (Vetaas 1997), the role of gaps in maintaining species diversity and regeneration in old-growth seasonally dry Shorea robusta forests (also known as Sal forests) in South East Asia is not fully understood. It is RESEARCH PAPER also not apparent if gap disturbance regimes and regeneration processes in Sal forests are similar to those in tropical and temperate forests (Barik et al 1992).…”

Diversity and regeneration of woody species were investigated in two ecological niches viz. gap and intact vegetation in old-growth seasonally dry Shorea robusta (Gaertn. f.) forests in Nepal. We also related varieties of diversity measures and regeneration attributes to gap characteristics. Stem density of tree and shrub components is higher in the gap than in the intact vegetation. Seedling densities of S. robusta and Terminalia alata (B. Heyne ex Roth.) are higher in the gap than in the intact vegetation, while contrary result is observed for T. bellirica (Gaertn. ex Roxb.) and Syzigium cumini (L. Skeels) in term of seedling density. The complement of Simpson index, Evenness index, and species-individual ratio in the seedling layer are lower in the gap than the intact vegetation. Gap size can explain species richness and species establishment rate. Gaps created by multiple tree falls in different years have higher seedling density of S. robusta than gaps created by single and/or multiple tree falls in the same year. In conclusion, gaps maintain species diversity by increasing seedling density, and favor regeneration of Sal forests. In addition to gap size, other gap attributes also affect species diversity and regeneration.
