• Introduction   

Accurate estimation of aboveground biomass is essential to better understand the carbon cycle in forest ecosystems.  相似文献

 Introduction   

The limited ability of Quercus species to regenerate naturally in Mediterranean forests has led to the development of various artificial regeneration methods; however, there is no general consensus as to what specific method is the best one for this purpose.  相似文献

• Background   

Among forest management practices, forest tree species substitution influences biogeochemical cycles and soil interactions rapidly (decades) and significantly.  相似文献   

5.

• Introduction   

Various processes contribute to shaping the local assemblage of species in hyperdiverse tropical forest. The relative contribution of environmental factors and dispersal limitation in determining the spatial distribution of saplings at local scale is unclear.  相似文献   

6.

Context   

Increased knowledge on diversity in wood properties would have implications both for fundamental research and for promoting a diversification of uses as material.  相似文献   

7.

Introduction   

Trees in two compartments of the mixed deciduous forest Draved Forest have been monitored regularly for 50 years.  相似文献   

8.

• Background   

Genetic selection for one trait can have an impact on other important traits for final use; thus, it is important to assess the correlation between traits.  相似文献   

9.

Introduction   

Windstorm is one of the most destructive environmental disturbance factors on forests, but its influence on conifer defense chemistry and susceptibility to insects and diseases is not well understood.  相似文献   

10.

Introduction   

Extrapolating plot data to broader spatial scales depends largely on environmental heterogeneity.  相似文献   

11.

Context   

Rotation length is known to affect timber quality in many plantation species, but its effect on the properties of Sitka spruce (Picea sitchensis) structural timber has not been quantified.  相似文献   

12.

Introduction   

We investigated changes in humus morphology and soil potential net N mineralization pathways along a pure beech even-aged forest chronosequence, composed of four stages (15, 65, 95, and 130 years old) on Luvisol.  相似文献

• Introduction   

In Cryptomeria japonica, heartwood properties are considered to be affected by specific extractives. It remains unclear whether traits of specific heartwood compounds are under genetic control.  相似文献

• Context   

In July 2005, a wildfire occurred in windthrown spruce forests in High Tatra Mountains and damaged roughly 229 ha of previously clear-cut area.  相似文献

• Context   

The suitability of thinning to prevent forest growth decline as a result of global warming has not been tested extensively in Macaronesian Canary pine (Pinus canariensis Sweet ex Spreng.).  相似文献

• Introduction   

Branch size and branch status (dead or alive) are important characteristics closely related to tree growth and wood quality. The aim of this study was to design models for the diameter and status of branches in Atlas cedar (Cedrus atlantica Manetti).  相似文献   

17.

• Introduction  

The interactive effects of water and nitrogen (N) on frost hardiness are not well known in broad-leaved trees. Furthermore, new environmental conditions may favour naturally generated hybrids between native and introduced tree species over native species.  相似文献   

18.

Introduction   

The aims of this study were to identify the climatic conditions controlling the distribution of Sasamorpha borealis and to assess the impact of climate change on the species in Japan.  相似文献   

19.

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

Introduction   

Forest fuel management in the context of fire prevention generally induces heterogeneous spatial patterns of vegetation. However, the impact of the canopy structure on both wind flows and fire behavior is not well understood.  相似文献
