• Introduction
Atmospheric deposition is an important input of major nutrients into forest ecosystems. The long-term goal of this work was to apply stable isotope methodology to assess atmospheric nutrient deposition in forest systems. 相似文献3.

• Introduction
Understanding diameter growth of the Mediterranean pine species is fundamental for evaluating and making appropriate strategic decisions in forest management. A matrix diameter growth model for two Mediterranean pine forest ecosystems in Spain has been developed. 相似文献4.

• Introduction
Accurate estimation of aboveground biomass is essential to better understand the carbon cycle in forest ecosystems. 相似文献5.
• Background
Maritime pine (Pinus pinaster Ait.) is a common conifer species in Portugal that contributes significantly to the national economy. Accurate classification of forest productivity based on site index and height growth dynamics is the main basis for sustainable forest management of this species. 相似文献6.
• 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7.

• Background
To assess ozone risks to temperate deciduous forest trees in East Asia, the stomatal ozone uptake was estimated based on a flux-based modeling approach. 相似文献8.

Introduction
Sight-based field measurements of tree crown projection area and canopy height are common praxis in forest science but difficult to validate. We quantified their measurement errors based on the virtual representation of an 11-species old-growth forest provided by high-resolution terrestrial LIDAR (light detection and ranging) measurements. 相似文献9.
Background
How environmental factors affect forest regeneration is relevant for systems that depend partially or fully on natural regeneration. 相似文献10.

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11.

• Context
In long-term forest monitoring, tree crown condition has been visually rated to diagnose tree vigor and forest condition. However, visual estimates are subjective. A semiautomatic image analysis system, called CROCO, was developed to estimate crown condition quantitatively. CROCO calculates a DSO value which decrease with increasing crown transparency. 相似文献12.

Introduction
Future climatic scenarios demand an increasing involvement of management for forest preservation, but little is known on how forestry practices will benefit stands in facing variation of climatic components. 相似文献13.
Tourism-induced deforestation outside Changbai Mountain Biosphere Reserve,northeast China 总被引:1,自引:0,他引:1
• Introduction
Old-growth forests on Changbai Mountain are economically and ecologically important but have been fragmented outside Changbai Mountain Biosphere Reserve. The trend of forest landscape degradation on Changbai Mountain threatens forest sustainability and biodiversity conservation in the region. Previous studies have focused mainly on the structure and function of protected forests but have ignored managed forests outside the reserve border. 相似文献14.

• 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15.
• Introduction
The wavelet-based functional approach was evaluated for modelling tree taper of jack pine (Pinus banksiana Lamb.) trees grown in the Canadian boreal forest region. 相似文献16.
•Introduction
The agricultural landscape in Eastern Canada has drastically changed in the last decades. Whilst certain forest communities are disappearing, post-agricultural forests are emerging from old fields colonized by fast-growing tree species. 相似文献17.

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18.

• Introduction
Most temperate forests are managed for wood production, and some forestry practices generate typical environmental features such as roads, paths, ditches and tractor ruts, which are likely to affect forest species distribution. 相似文献19.
• Introduction
Xeric (trailing) forest range limits are particularly vulnerable to impacts of predicted climate change. Regional modelling studies contribute to the identification of potential local climatic threats and may support appropriate management strategies. 相似文献20.
