Determining the rate of change in a mixed deciduous forest monitored for 50 years

Introduction   

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

Drought and frost resistance of trees: a comparison of four species at different sites and altitudes

Context   

Drought and frost resistances are key factors for the survival and distribution of tree species.     

Segregation of <Emphasis Type="Italic">Eucalyptus tereticornis</Emphasis> Sm. clones for properties relevant to solid wood products

Introduction   

Wood quality is an important criterion in the selection of superior genotypes when breeding for solid wood.     

Genetic variation in traits affecting sawn timber recovery in plantation-grown <Emphasis Type="Italic">Eucalyptus nitens</Emphasis>

• Introduction   

There is increasing interest in managing Eucalyptus nitens plantations for sawn timber production.     

Drought induces opposite changes in the concentration of non-structural carbohydrates of two evergreen <Emphasis Type="Italic">Nothofagus</Emphasis> species of differential drought resistance

• Introduction   

One current explanation for worldwide drought-induced tree mortality states that reduced photosynthesis and continued respiration lead to carbon depletion and eventually to carbon starvation.     

Genetic variation of chemical and mechanical traits of maritime pine (<Emphasis Type="Italic">Pinus pinaster</Emphasis> Aiton). Correlations with wood density components

• 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.     

Artificial regeneration with <Emphasis Type="BoldItalic">Quercus ilex</Emphasis> L. and <Emphasis Type="BoldItalic">Quercus suber</Emphasis> L. by direct seeding and planting in southern Spain

 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.     

Changes within collembolan communities in windthrown European montane spruce forests 2 years after disturbance by fire

• 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.     

Using multiscale spatial analysis to assess fire ignition density in Catalonia,Spain

Introduction   

This article explores the possibility of including multiple spatial scales into a mixed model for predicting the density of human-caused fire ignitions in Catalonia (North-East Spain).     

Are plot data effective for landscape prediction? A simulation study of tree species response to climate warming under varying environmental heterogeneity

Introduction   

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

Freezing-induced loss of carbon uptake in a subtropical coniferous plantation in southern China

• Context  

In January 2008, a freeze in southern China, unprecedented in 50 years, severely affected local subtropical coniferous plantations.     

Synergistic use of very high-frequency radar and discrete-return lidar for estimating biomass in temperate hardwood and mixed forests

• Introduction   

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

Is selective thinning an adequate practice for adapting <Emphasis Type="Italic">Quercus ilex</Emphasis> coppices to climate change?

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.     

Applying wavelet-based functional approach in modelling tree taper

• 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.     

Automatic detection of sound knots and loose knots on sugi using gray level co-occurrence matrix parameters

• Context  

Knowledge of the occurrence of sound and loose knots on the surface of sawn sugi (Cryptomeria japonica L.f.) is important for its grading and application.     

Changes in forest structure and composition on Changbai Mountain in Northeast China

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.     

Climatic variability and other site factor influences on natural regeneration of <Emphasis Type="Italic">Pinus pinaster</Emphasis> Ait. in Mediterranean forests

Background  

How environmental factors affect forest regeneration is relevant for systems that depend partially or fully on natural regeneration.     

Contribution of forest management artefacts to plant diversity at a forest scale

• 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.     

Multinomial logit estimation of a diameter growth matrix model of two Mediterranean pine species in Spain

• 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.     

Nonlinear fixed and random generalized height–diameter models for Portuguese cork oak stands

• Objective   

The objective of the research was to develop a generalized height–diameter model for Quercus suber L. in Portugal, which can be applied both to undebarked and debarked trees, with diameter at breast height over cork larger than 2.5 cm.
