• Introduction
Non-structural carbohydrates and phenolic compounds are implicated in the natural durability of wood. In order to find the chemical traits of natural durability in teak wood, the radial distribution of phenolics compounds and non-structural carbohydrates were studied in trees ranked by contrasting natural durability class against Antrodia sp. 相似文献2.

Introduction
Long-term ecological studies are essential for understanding the dynamics of natural systems. However, describing long-term dynamics in old-growth forests is often hindered by a lack of archival data. 相似文献3.
Background
How environmental factors affect forest regeneration is relevant for systems that depend partially or fully on natural regeneration. 相似文献4.

Introduction
The old-growth forests on Changbai Mountain have been well protected from human activities and provide a living laboratory for studying forest carbon sequestration under natural environmental conditions. 相似文献5.

• Introduction, Material and Methods
The genetic structure and diversity of ten natural populations of Juniperus phoenicea L. from the western part of the species range have been studied using random amplified polymorphic DNA (RAPD) markers. 相似文献6.
Introduction
Important nutrients in forest soils such as nitrogen and phosphorus are mostly recycled from natural polymeric compounds contained in litter and organic debris—for example nucleic acids, proteins, or chitin. 相似文献7.

•Introduction
Silviculture systems applied in Nothofagus pumilio forests are based on opening the canopy to stimulate natural regeneration by modifying light and soil moisture. The objective is to evaluate regeneration dynamics of N. pumilio along different forest canopy and solar radiation gradients. 相似文献8.
• Context
Landscape structure is crucial for forest conservation in regions where the natural forest is fragmented. Practical conservation is currently shifting from local stands to a landscape perspective, although few studies have tested the relative effects of different spatial scales on plant species composition and diversity in forests. 相似文献9.
Context
The thermal dissipation method to measure sap flow in tree stems can be used with cyclic heating to reduce electricity consumption and/or to account for natural temperature gradients. Nevertheless, errors in sap flow estimation can be introduced because the thermal equilibrium has not been reached at the measurement time. 相似文献10.
• Introduction
We present a study on genetic variation in natural durability traits of young-aged Eucalyptus cladocalyx, a species adapted to temperate, low rainfall regions. Our motivation was the production of naturally durable posts for applications such as vine trellises, a sector dominated by heavy metal preservative-treated wood in some of the world’s main wine-producing countries. 相似文献11.

Background
The potential of forest to regenerate after harvesting is a key element for sustainability of the ecosystem. For semi-arid tropical savanna environments, managing resprouts after tree cutting is ideally suited because of the natural ability of many indigenous species to regenerate vegetatively. Regeneration in this ecosystem is, however, prone to many disturbance factors such as fire and grazing by livestock. 相似文献12.
Introduction
The artificial regeneration of oaks (Quercus spp.) can supplement deficient natural regeneration, yet growth and physiology of newly planted seedlings are often negatively affected by animal herbivory. Alternative nursery stock types with improved stress resistance may help improve regeneration success. 相似文献13.

Introduction
The great spatial and temporal heterogeneity of Mediterranean ecosystems can influence establishment success in woody species, whose natural regeneration occurs to a very small extent. In this work, the effect of the spatial pattern of environmental variables (light availability, soil moisture and herbaceous production) on seedling emergence, growth, survival and establishment success was examined by using a spatially explicit approach. 相似文献14.
Background
Plant resources in natural ecosystems are frequently spatially structured at a scale relevant to individuals. This spatial structure can be variable in time, and can even vary within a single growing season. Several leaf traits may show spatial structure at the same scale as light or soil resources. However, whether this spatial structure stays constant from one growing season to the next is still unknown. 相似文献15.

• Introduction
This study presents a method for estimating the minimum area which exhibits a balanced diameter distribution, and the corresponding number of trees, for different tree species and forest types in the Santiago Papasquiaro region in the State of Durango, Mexico. The balanced structure area is defined as the minimum contiguous area that is required for sustainable management of a multi-sized selection forest. A multi-sized forest represents a balanced structure unit if the relationship between harvest and growth can be maintained, using a defined target diameter distribution and disregarding major natural disturbances. The study is based on 17,577 sample plots in uneven-aged forests, which are selectively harvested by local communities. 相似文献16.
