“…This distribution of homobaric and heterobaric leaves in different strata appears to be due to micro-environmental gradients associated with the various forest strata (Kenzo et al 2007). Such gradients include light availability, temperature, vapor pressure deficit, and wind (Théry 2001;Kitajima & Poorter 2010;Bennett et al 2015;Inoue et al 2015). Of these, light availability is particularly important because it can influence the growth, survival, and subsequent reproduction of young individuals (Chazdon et al 1996;Valladares & Niinemets 2008).…”

“…In forests, variation in abiotic features along vertical stratifi cation provokes diff erent adjustments by plants for better use of the environmental conditions of each stratum (Valladares & Niinemets 2008;Niinemets 2010;Inoue et al 2015). Such adjustments can be morphological, physiological, and/or phenological.…”

“…Such structural differences are reflected in the functional proprieties of these leaf types (Kenzo et al 2007;Pieruschka et al 2010;Lynch et al 2012;Inoue et al 2015). The presence of BSEs can protect leaf lamina from hydric stress and increase light absorption and mechanical support (Terashima 1992;Karabourniotis 1998;Nikolopoulos et al 2002;Rhizopoulou & Psaras 2003).…”

In ombrophilous forests, light stratifi cation provokes diff erent adjustments by plants for better use of the environmental conditions of each stratum. Among the morphological traits that vary with strata, the presence of bundle sheath extensions (BSEs) is related to water transport, photosynthesis, and leaf mechanical support and classifi es leaves as homobaric or heterobaric. Th is study analyzed the proportion of these types of leaves in a Lowland Ombrophilous Dense Forest (LLODF) and a Mixed Ombrophilous Forest (MOF), and among the strata of each forest type. Th e morphological leaf traits of 89 LLODF tree species and 57 MOF tree species were examined. Th e proportion of homobaric and heterobaric leaves did not diff er between forests. However, in both forest types, the distribution of species with heterobaric or homobaric leaves depended on strata, with heterobaric species occurring mainly in higher strata, and homobaric species in lower strata. Th us, light stratifi cation acts as an ecological fi lter on the composition of the vegetation of these forests, favoring heterobaric species in places with higher light intensity and temperature, such as the highest strata of canopy. On the other hand, homobaric species are more frequent in lower strata, where light is less available and humidity higher.

“…The upper canopy environment with high photosynthetic productivity may allow symbiosis with EcM fungi, which may have a higher carbohydrate demand than AM fungi (de Kroon and Visser 2003;Smith and Read 2008). In fact, dominant dipterocarp trees in the emergent layer showed higher photosynthetic ability under upper canopy conditions than most non-dipterocarp trees or lower trees when they were in the emergent layer (Kenzo et al 2015b;Inoue et al 2015). Canopy, sub-canopy, and understory species showed significantly negative leaf d 15 N values, with large variation.…”

Key message Large variations in leaf d 15 N in Bornean tropical rainforest trees may indicate that various tropical species have species-specific strategy for nitrogen uptake under low soil nutrient conditions, including root symbiotic microorganisms such as ectomycorrhiza.Abstract Lowland tropical rainforests in Southeast Asia are characterized by high species diversity despite limited soil nutrient conditions. The plant nitrogen isotope ratio (d 15 N) reflects plant uptake of soil nitrogen. We analyzed d 15 N values and nitrogen content (N %) in leaves and roots of 108 woody species with different types of symbiotic microorganisms, of different life forms (emergent, canopy, sub-canopy, understory, and canopy gap species), and from different families in a Bornean lowland dipterocarp forest to gain more insight into the diversity of nitrogen uptake strategy in the rhizosphere. Leaf d 15 N values in the species studied varied largely from -7.2 to 5.0 %, which is comparable to the values of known Asian trees including temperate, sub-tropical, and tropical mountain forests. Leaf d 15 N also varied significantly among both life forms and families, though the phylogenetically independent contrast (PIC) relationships were not statistically significant among life form, family, and symbiotic types. Some families showed specific leaf d 15 N values; Dipterocarpaceae, the dominant family in the canopy layer with symbiotic ectomycorrhiza in Southeast Asia, had small intraspecific variation and higher leaf d 15 N values (0.03 %) compared with species exhibiting arbuscular mycorrhiza, whereas several families such as Burseraceae, Euphorbiaceae, and Myrtaceae showed large interspecific variation in leaf d 15 N (e.g., from -7.2 to 5.0 % in Euphorbiaceae). These variations suggest that tropical species may have family-or species-specific strategy, such as root symbiotic microorganisms, for nitrogen uptake under low-nutrient conditions in tropical rainforests in Southeast Asia.

“…The traits of stem woody parts, namely wood density and water content, have a strong relationship with their functional traits, such as drought tolerance, crown architecture, growth rate, survival, and photosynthesis, especially in tropical forests (Bucci et al 2004, Hiromi et al 2012, Inoue et al 2015, Ishida et al 2008, Kenzo et al 2011, Markesteijn et al 2011, Martin et al 2013, Santiago et al 2004. For example, trees with low wood density exhibit a faster growth rate compared with trees of high wood density, whereas trees with high wood density usually have a high survival rate due to their stronger resistance to physical stress, pathogens, and pest attacks (Curran et al 2008, King et al 2005, 2006, Kitajima 1994.…”

We compared wood density (WD) and water content (WC) between a dry evergreen forest (DEF) and dry deciduous forest (DDF) in central Cambodia. Wood core samples of 53 species from DEF and 54 species from DDF were collected. Average WD and WC in all species were similar between DEF (0.64 g/cm 3 of WD; 0.40 g/cm 3 of WC) and DDF (0.64 g/cm 3 of WD; 0.42 g/cm 3 of WC), although the average WC of five tree species that appeared in both forest types was higher in DDF than that in DEF. Tree size effects on WD and WC were negligible in both DEF and DDF. Intraspecific differences of those effects on WD and WC were also not observed in major canopy species in DDF and DEF, except for WD of Shorea obtusa in DDF, whose value increased with increasing tree diameter. Tree life-forms such as canopy, subcanopy, and understory species did not affect WD and WC in both forest types, although canopy gap species in DEF showed the smallest WD among the life-forms. The relationships between WD and WC in DEF and DDF were negatively correlated, and both regression equations did not differ between forest types. Overall, there were little differences on average WD and WC between DEF and DDF trees, even though their species composition and tree ecological traits were significantly different between forest types in central Cambodia.Discipline: Forestry and forest products Additional key words: Biomass, plant functional group, REDD+, wood specific gravity, Dipterocarpaceae IntroductionTropical dry forests occur in the Indochina Peninsula, which experiences severe dry spells, sometimes lasting several months without rainfall. In this region, there are two distinct types of dry forests in lowland areas (Ashton 2014, Hozumi et al. 1969, Ogawa et al. 1965, namely dry evergreen forests (DEF) and dry deciduous forests (DDF). Cambodia is located in the center of the peninsula and still maintains relatively high forest coverage (59.1% in 2006) compared with adjacent countries in the same This paper reports the results obtained in the project on "Estimation and simulation of carbon stock change of tropical forest in Asia
