able information on relationships between size—expressed in terms of diameter and dry biomass—and hydraulic efficiency of woody structures at different scales, from stem segments to whole trees. Three data sets were constructed: the first described the relationship between segment diameter and hydraulic conductivity (kh; kg m s –1 MPa) in four species; the second, for the same four species, des...

Tree growth, especially diameter growth of tree stems, is an important issue for understanding the productivity and dynamics of forest stands. Metabolic scaling theory predicted that the 2/3 power of stem diameter at a certain time is a linear function of the 2/3 power of the initial diameter and that the diameter growth rate scales to the 1/3 power of the initial diameter. We tested these pred...

Tree growth takes place at different time scales ranging from hours to days. To understand responses climate, continuous high-resolution measurements of tree diameter variations are needed, which usually obtained with automatic dendrometers. Here, we monitored stem increment Quercus faginea Lambert growing in central Portugal determine the effect climate on daily and seasonal dynamics during 20...

This study is part of a larger project aimed at quantifying the biomass and biomass increment of an experimental beech stand aged 30 years, and comparing the carbon sequestration in trees to carbon fluxes. The below ground part of trees is expected to play an important role in carbon sequestration. A method has been developed to estimate the biomass and biomass increment of coarse, small and fi...

The influence of three types treatment on seedling survival percentage, growth and Armillaria infestation Fagus sylvatica L. (FAGUS), Abies alba Mill. (ABIES) Picea abies (L.) H. Karst. (PICEA) seedlings were tested in this study: (i) inoculation with the Ectovit® preparation containing ectomycorrhizal fungi (INOCUL), (ii) + Conavit® fertilizer (INOCUL FERTILIZ) (iii) untreated group (CONTROL)....

Mixed-species stands have been found to be more productive than would expected from the performance of their component species in monocultures due facilitation and complementarity between species, although these interactions depend on combination present. Our study focuses monospecific mixed-species Scots pine Norway spruce using 20 triplets established nine countries along a climatic gradient ...

The first commercial thinning usually entails a high cost in harvest operations and low resulting income. From practical forestry perspective, schematic spatial selection might be more efficient than selective approach. Therefore, this study aimed to compare basal area, total standing volumes, periodic annual increment (PAI), as well stand structure, between different designs (selective thinnin...

Projection of stand development over time relies on accurate height–diameter functions. In complex forests where trees of various ages, species, sizes, vigor and crown classes, and shade tolerance levels coexist, tree height predictions are more difficult than in uniform conditions. In such complex situations, individual tree height–diameter relationships and predictions are often further compl...

The effect of forest harvesting on the composition and structure a temperate coniferous in Mexico was evaluated after three periods from 2007–2015. In this forest, we identified seven families eight tree species. dominant species is Pinus pseudostrobus Lindl. which also most important commercial Harvesting oriented towards increasing abundance pine species, resulting decrease diversity favoring...
