The least-cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has to cope with th...
Crown development of beech crop trees under different thinning regimes
target trees crown parameters Fagus sylvatica Linnaeus tending
2017/6/26
Crop trees are the main bearers of qualitative and value production of the stands. Although the number and production of the mentioned trees are affected by various factors, crown development by means...
Comparison of different non-linear models for prediction of the relationship between diameter and height of velvet maple trees in natural forests (Case study: Asalem Forests, Iran)
height-diameter model Acer velutinum north of Iran
2016/3/2
Velvet maple (Acer velutinum) is one of the woody species in the Hyrcanian forests. In this study, the relationship between height and diameter of velvet maple was surveyed. A complete list of the sel...
Microsatellite DNA Markers in Shorea platyclados (Dipterocarpaceae): genetic diversity, size homoplasy and mother trees
dipterocarp timber identification certification
2015/5/5
Cross-specific amplification of microsatellite loci greatly enhances the effectiveness of this marker
system. This shortcut would greatly enhance our examination of the gene flow and population stru...
Growth and characteristics of old beech (Fagus sylvatica L.) trees individually dispersed in spruce monocultures--
beech old trees interspersed trees tree size tree crown competition regeneration spruce monoculture
2015/3/19
We studied old beech trees individually dispersed in spruce monocultures after having found wildlings in their vicinity. The goal was to define stem and crown dimensions of the trees in dependence on ...
Plant defense, herbivory, and the growth of Cordia alliodora trees and their symbiotic Azteca ant colonies
Allometry Ant–plant mutualism Chamela-Cuixmala Biosphere Reserve
2015/11/13
The effects of herbivory on plant fitness are
integrated over a plant’s lifetime, mediated by ontogenetic
changes in plant defense, tolerance, and herbivore pressure.
In symbiotic ant–plant m...
Forests beyond trees: NTFPs as tools for climate change mitigation and adaptation
climate change trees
2014/5/7
Traditionally, climate change eorts targeted at forests focused on trees as a
means to protect and create forest carbon stocks. Forests, however, are more
than just trees – they can be div...

Distribution of the moisture content across stem wood at breast height in Acacia mangium, A. auriculiformis,and hybrid Acacia trees grown in 3 Asian countries was evaluated. Moisture contents of the s...
Construction of a Volume Table for Evergreen Broad-leaved Trees with Pipe Model Theory and Relative Stem Curve: A Case Study in the Tokyo University Forest in Chiba,Japan
branch broad-leaved tree pipe model relative stem curve volume table
2009/8/28
In this paper we constructed a volume table for broad-leaved trees including a stem and branches using a relative stem curve, provided that the trees are subject to the pipe model theory. First we mea...
Regeneration Process of Broadleaved Trees in Planted Larix kaempferi Forests
broadleaved tree buried viable seed planted larch forest regeneration habit thinning
2009/8/27
To examine the regeneration process of broadleaved trees in planted larch (Larix kaempferi) forests, we investigated stand structures, species compositions and age distributions of broadleaved trees r...
Distance Dependent Emergency of Beech (Fagus crenata) Seedlings from Mother Trees in Heavy Snowfall Area:The Effects of Snow Covers to Protect Seeds from Predation by Rodents
beech seedling bank seed predation snow cover
2009/8/24
Seedling banks in a beech forest were scarcely found around stems in snowy regions. Since snow cover prevents feeding activity of rodents, we considered that the seed predation might occur intensively...
