Large-diameter trees dominate the structure, dynamics and function of many temperate and tropical forests. Although both scaling theory and competition theory make predictions about the relative composition and spatial patterns of large-diameter trees compared to smaller diameter trees, these predictions are rarely tested. We established a 25.6 ha permanent plot within which we tagged and mappe...

BACKGROUND AND AIMS Wood density is a key variable for understanding life history strategies in tropical trees. Differences in wood density and its radial variation were related to the shade-tolerance of six canopy tree species in seasonally dry tropical forest in Thailand. In addition, using tree ring measurements, the influence of tree size, age and annual increment on radial density gradient...
Projecting forest dynamics as a function of alternative management strategies and climatic conditions is key to develop sound policy planning. In Spain there need for full set climate-sensitive individual-tree growth yield models suitable country-level simulations. this paper we present environmentally driven stand based on distance-independent yield. The data model calibration are the second, ...
This paper aimed to determine the quality indexes for and cellulose based on fiber features from two wood species of interest, Eucalyptus pellita E. tereticornis. The mean annual increment (IMA) was calculated by measuring DBH Height (25 years), a 10 cm disk each tree collected density determinations anatomical studies paper. Tree height, trunk diameter at 1.30 m in height (DBH), volume per wer...
Abstract Mixed-species systems are well-suited to smallholder and community forestry, but reliable evidence regarding procedures assess species performance in such is scarce. This field trial uses a pair of clinal plots with varying spacing composition gain insights into competition between four proposed for landscape rehabilitation the Philippines. We examine efficiency this compact revealing ...
In two experiments we looked at the effects of the color of equiluminant backgrounds on simple reaction time (RT) to increment and decrement spot-stimuli varying in diameter. When comparing both red vs blue and red vs green backgrounds, we found that for the smallest diameter stimuli, RTs tended to be faster with red background; however, as the diameter of the stimuli increased, RTs were faster...
