Buttress trees are prominent in tropical rainforests, providing mechanical support for canopy trees. Other ecological functions of these structures remain unclear. Here we demonstrate that buttresses are physical structures that regulate soil moisture, soil nutrient status and seedling diversity near tree trunks. We monitored soil moisture over a year in plots on the uphill, downhill and lateral sides of buttresses on a tropical seasonal rainforest slope in Xishuangbanna, Southwest China. Soil… Expand

Buttresses induced habitat heterogeneity increases nitrogen availability in tropical rainforests
It is suggested that buttresses accelerate nitrogen cycling at microhabitat scale and form habitat heterogeneity on a landscape scale (forest floor), which forms pockets of mineral N reserves and simultaneously increases supply of plant available N in the tropical rainforests. Expand
Rainwater harvest influences habitat heterogeneity, nutrient build up and herbage biomass production in Aravalli hills of Rajasthan, India
The effect of rainwater harvesting (RWH) on microhabitat differentiation, herbage biomass and biomass allocation to roots was investigated in relation to rehabilitation of degraded hillyExpand
Buttress trees in a 20-hectare tropical dipterocarp rainforest in Xishuangbanna, SW China
It is found that although Buttress formation is not a fixed species characteristic, there is a strong phylogenetic signal for buttress formation in larger species. Expand
Photosynthetic characteristics of an endangered speciesTetrameles nudifloraunder different light and water conditions
The purpose was to confirm whether Tetrameles nudiflora was a heliophilous plant or not, and how it responded to drought stress, which would be very important for the in 鄄 situ and ex鄄situ protection of TetramELes nudIFlora in monsoon climate areas. Expand
Buttressing impact on diameter estimation in plantation teak (Tectona grandis L.f.) sample trees in northern Thailand
Buttressing consists of ground-upward deformations from the circular cross section of a tree and can be quite pronounced in tropical species, thus making the measurement of lower diameters in olderExpand
Root biomechanics in Rhizophora mangle: anatomy, morphology and ecology of mangrove's flying buttresses.
This study tests the hypothesis that rhizophore architecture in R. mangle co-varies with their proximity to the main stem, and with stem size and crown position, and provides a unique strategy to increase tree slenderness and height in the typically unstable substrate on which the trees grow, at a site that is subject to frequent storms.

Mechanisms for the successful biological restoration of the threatened African pencilcedar (Juniperus procera Hochst. ex. Endl., Cupressaceae) in a degraded landscape
It is concluded that successful restoration of Juniperus procera in degraded landscapes and across the species’ range of habitats is feasible provided that strong and well-fortified stecklings are established along with the N 2 -fixing, fast-growing and drought-tolerant Acacia abyssinica. Expand
Restoring tropical rain forests
There have been signs that the decline in deforestation in the Amazon area is bottoming out, partly reflecting the fact that Brazil's efforts have targeted large clearances of 500 hectares or more while current deforestation is occurring chiefly in smaller plots. Expand

Effects of seasonal drought on gap and understorey seedlings in a Bolivian moist forest
A high growth during the wet season provided gap plants with a decisive size advantage over understorey plants during the dry season, which led to a shorter deciduous period for Cedrela plants, although it did not lead to a higher plant growth. Expand
Seedling traits determine drought tolerance of tropical tree species
Functional traits of 38 tropical tree species from dry and moist forest were compared, and their ability to survive drought in a dry-down experiment in which wilting and survival were monitored, to suggest how seedling traits affect drought survival, and how drought survival determines species distribution along the rainfall gradient.

Seedling growth responses to water and nutrient augmentation in the understorey of a lowland moist forest, Panama
It is shown that soil resources influence growth rates even in the deep shade of the forest understorey, and different responses to soil resources among species that might contribute to niche differentiation and species coexistence are demonstrated. Expand
The influence of nitrogen on rain forest dipterocarp seedlings exposed to a large increase in irradiance
It is suggested that variations in N-availability may have a much greater impact on the relative competitiveness of dipterocarp seedlings during the regenerative phase following canopy gap formation than physiological differences between seedlings. Expand
Double-funneling of trees: Stemflow and root-induced preferential flow
ABSTRACT Trees partition rainfall into throughfall and stemflow, resulting in a spatial distribution of nutrient and water fluxes reaching the soil centred on the trunks of trees. Stemflow fluxes ofExpand
The ecology of very small-seeded shade-tolerant trees and shrubs in lowland rain forest in Singapore
A study was made in Bukit Timah Nature Reserve of niche differentiation among 11 woody species that have very small seeds (22–460 µg) and establish in deep shade, i.e., where the indirect site factorExpand
Buttresses of tropical rainforest trees influence hillslope processes
During heavy rainfall events, the buttresses of tropical rainforest trees limit the occurrence of stemflow-generated overland flow and soil erosion on hillslopes. Buttresses promote infiltration byExpand
Soil nutrients influence spatial distributions of tropical tree species
It is found that belowground resource availability plays an important role in the assembly of tropical tree communities at local scales and provide the basis for future investigations on the mechanisms of resource competition among tropical tree species. Expand

Buttress form of the central African rain forest tree Microberlinia bisulcata, and its possible role in nutrient acquisition
Buttressing is a trait special to tropical trees but explanations for its occurrence remain inconclusive. The two main hypotheses are that they provide structural support and/or promote nutrientExpand
