Climate has a larger effect than stand basal area on wood density in Pinus ponderosa var. scopulorum in the southwestern USA

Stand basal area of ponderosa pine ( Pinus ponderosa var. scopulorum Engelm.) in the US Southwest has little effect on the density of the wood produced, but climatic fluctuations have a strong effect. Wood density increases during

Seasonal adjustment of primary and secondary growth in maritime pine under simulated climatic changes

Reducing irrigation by up to 75% in spring decreased primary and secondary growth in Pinus pinaster Aiton saplings, whereas an extra irrigation in September prompted secondary growth, confirming the high plasticity of xylogenesis in this species. Context

The utility of terrestrial photogrammetry for assessment of tree volume and taper in boreal mixedwood forests

This study showed that digital terrestrial photogrammetry is able to produce accurate estimates of stem volume and diameter across a range of species and tree sizes that showed strong correspondence when compared with traditional inventory techniques. This

The conifer-curve: fast prediction of hydraulic conductivity loss and vulnerability to cavitation

The relationship between relative water loss (RWL) and hydraulic conductivity loss (PLC) in sapwood is robust across conifer species. We provide an empirical model (conifer-curve) for predicting PLC from simple RWL measurements. The approach is regarded as

Genetic variation and early selection in Larix decidua Mill. from progeny test in Romania

High genetic variation and determinism for quantitative traits of Larix decidua Mill. were found in a progeny test established at its south-eastern limit of distribution area. The top range families are from both native populations and artificial

Monitoring disturbance intervals in forests: a case study of increasing forest disturbance in Minnesota

We develop analytical methods and explore trends in disturbance interval via systematic forest inventory observations at a bioregional scale. Context Our study spans the dynamic ecotone at the intersection of southern boreal forest, mixed hardwood forest, and

The relationship between climate and the intra-annual oxygen isotope patterns from pine trees: a case study along an elevation gradient on Corsica, France

Intra-annual oxygen isotope patterns of tree-ring cellulose from Pinus nigra subsp. laricio and Pinus pinaster along an elevation gradient can be divided into four distinct patterns ((1) high values in the beginning of the tree ring, declining

Increasing temperatures over an 18-year period shortens growing season length in a beech (Fagus sylvatica L.)-dominated forest

Using long-term measurements in a mature beech (Fagus sylvatica L.)-dominated forest located in east Belgium, this paper showed that spring and autumn temperature increases during the last two decades led to an earlier end and a shortening

Xylogenesis of Pinus radiata D. Don growing in New Zealand

Pinus radiata D. Don growing in the central North Island of New Zealand did not show full winter cambial dormancy. While there was a brief cessation of cambial cell division during June (winter), cell wall thickening, secondary

Size-density trajectories for even-aged sessile oak (Quercus petraea (Matt.) Liebl.) and common beech (Fagus sylvatica L.) stands revealing similarities and differences in the mortality process

We studied the size-density trajectories of pure even-aged unthinned experimental sessile oak ( Quercus petraea (Matt.) Liebl.) stands in the ranges of 994–135,555 trees per hectare initial densities, observed from the ages of 5 to 38. We
