Soil-related performance variation and distributions of tree species in a Bornean rain forest
1 Spatial distributions of tropical trees often correlate with environmental variation, suggesting that ecological sorting caused by niche differentiation may be important for maintaining species diversity. 2 Four soil types have been identified in a 52-ha forest dynamics plot in Bornean mixed dipterocarp forest (ranked by increasing fertility and moisture: sandy loam, loam, fine loam, and clay...
متن کاملCan Makjong (scaphium Macropodum) Powder Formed Gel in Effervescent Blend?
Objective: The aim of this preliminary study was to investigate gel forming of Makjong powder in effervescent blend and evaluate the probability to develop Makjong effervescent powder formulation for medicinal and beverage applications. Methods: Blank effervescent blend consisted of citric acid, tartaric acid, and sodium bicarbonate with different ratio was prepared. The effervescent blends wer...
متن کاملRelaxation of species-specific neighborhood effects in Bornean rain forest under climatic perturbation.
Evidence of negative conspecific density dependence (NDD) operating on seedling survival and sapling recruitment has accumulated recently. In contrast, evidence of NDD operating on growth of trees has been circumstantial at best. Whether or not local NDD at the level of individual trees leads to NDD at the level of the community is still an open question. Moreover, whether and how perturbations...
متن کاملDo Tree Species in a Bornean Mixed Dipterocarp Forest Display Preferential Uptake of Different Nitrogen Forms?
Lambir Hills National Park in Malaysian Borneo is composed of dipterocarp tree species which specialize on different soil types. Although the mechanisms contributing to this distribution of tree species are unknown, one hypothesis is that tree species at Lambir differ in their preferences for different nitrogen forms. In this study we investigated (1) whether clay soil and sandy loam soil types...
متن کاملComplementary resource use by tree species in a rain forest tree plantation.
Mixed-species tree plantations, composed of high-value native rain forest timbers, are potential forestry systems for the subtropics and tropics that can provide ecological and production benefits. Choices of rain forest tree species for mixtures are generally based on the concept that assemblages of fast-growing and light-demanding species are less productive than assemblages of species with d...
