Temporal changes in the spatial pattern of leaf traits in a <Emphasis Type="Italic">Quercus robur</Emphasis> population

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.     

Autumn fertilization of <Emphasis Type="Italic">Quercus ilex</Emphasis> ssp. <Emphasis Type="Italic">ballota</Emphasis> (Desf.) Samp. nursery seedlings: effects on morpho-physiology and field performance

• Background   

The Holm oak (Quercus ilex ssp. ballota [Desf.] Samp.) is an evergreen tree widely distributed in the western Mediterranean Basin. Forest restoration programs using this species have enjoyed only limited success, and knowledge concerning the effect of fertilization on plant quality and post-transplantation response is sparse.     

Distribution and plant community associations of the understory bamboo <Emphasis Type="Italic">Fargesia qinlingensis</Emphasis> in the Foping National Nature Reserve,China

• Introduction  

Fargesia qinlingensis is the primary food source for the endangered giant panda during the summer months in the Qinling Mountains, but little is known about its spatial distribution and plant community associations.     

Photosynthetic assimilation and carbohydrate allocation of <Emphasis Type="Italic">Quercus rubra</Emphasis> seedlings in response to simulated herbivory

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.     

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.     

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).     

Impacts of tree canopy structure on wind flows and fire propagation simulated with FIRETEC

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.     

The relative importance of dispersal limitation and habitat preference in shaping spatial distribution of saplings in a tropical moist forest: a case study along a combination of hydromorphic and canopy disturbance gradients

• 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.     

At which spatial scale are plant species composition and diversity affected in beech forests?

• 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.     

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.     

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.     

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 <Emphasis Type="Italic">Pinus taeda</Emphasis> wood properties predicted using non-destructive techniques

• Background   

Tree breeders have been reluctant to include wood traits in tree improvement programs owing to logistic difficulties and the cost associated with the assessing the traits.     

Predicting the growth and yield of <Emphasis Type="Italic">Pinus radiata</Emphasis> in Bolivia

Context   

Pinus radiata D. Don is the most widely planted conifer in the Inter-Andean Valleys of Bolivia. However, Bolivia lacks knowledge on stand dynamics and yield prediction of radiata pine, and the particular Bolivian conditions prevent a straightforward application of equations developed elsewhere.     

Molecular cytogenetics and flow cytometry reveal conserved genome organization in <Emphasis Type="Italic">Pinus mugo</Emphasis> and <Emphasis Type="Italic">P. uncinata</Emphasis>

• Introduction   

The most common representatives of the European mountain pine complex (Pinus mugo s.l.) are P. mugo s.s. and Pinus uncinata.     

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 and demographic contraction of the remnant populations of Mexican Caribbean pine (<Emphasis Type="Italic">Pinus caribaea</Emphasis> var. <Emphasis Type="Italic">hondurensis</Emphasis>: Pinaceae)

• Introduction   

The recognition of endangered species takes into account geographic isolation and small size of populations, as is the case of two populations of Pinus caribaea var. hondurensis distributed in México.     

Comparison of postfire mortality in endemic Corsican black pine (<Emphasis Type="Italic">Pinus nigra</Emphasis> ssp. <Emphasis Type="Italic">laricio</Emphasis>) and its direct competitor (<Emphasis Type="Italic">Pinus pinaster</Emphasis>)

• Introduction   

Laricio pine (Pinus nigra J.F. Arn. ssp. laricio (Poiret) Maire var Corsicana Hyl.) is a form of black pine endemic to Corsica, that may now be under threat due to current fire regimes and competition with maritime pine (Pinus pinaster Aiton).     

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.     

Effects of thinning intensity on radial growth patterns and temperature sensitivity in <Emphasis Type="Italic">Pinus canariensis</Emphasis> afforestations on Tenerife Island,Spain

• 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.).
