We quantified biomass and nutrient accumulation of Acacia dealbata Link and Eucalyptus globulus Labill. planted at stem densities of 5000 and 15000 ha 1 in a bioenergy plantation in Chile. We tested the hypotheses that species and stocking will not affect biomass or nutrient accumulation. Species and stocking did not affect biomass accumulation after five years; however, species and stocking di...

Cork value is determined mainly by its thickness at the moment of debarking but also affected presence any discontinuities related to porosity characteristics and/or anomalies in cork plank. quality closely final price raw material, so inventories conducted prior are aimed identifying and therefore potential price. Besides information from these inventories, forest managers need a reliable pred...
Shrub encroachment is a global phenomenon affecting the structure and function of grasslands (Eldridge et al., 2011). In European Alps, mainly green alder shrubs Alnus viridis [Chaix] DC. expand into formerly open habitats subalpine zone (Brändli 2020; Tasser & Tappeiner, 2002).

Thus, study objective was to identify perceptions local people concerning current state strategies Faso. investigate potential solutions threats pose...
The phenomenon of Oak decline is one of worrying phenomena that has been occurred in Zagros forests, and the extent of the infected forest areas is spread increasingly. The present study aims to investigate the symptoms of Oak decline on the individuals and its effect on the secondary compounds of Quercus brantii leaves. For this purposes, three forest regions including Abolivafa, Miankouh and ...
Norway spruce (Picea abies (L.) Karst.) bark contains marked amounts of polyphenolic compounds. Condensed tannins (CTs) and stilbenes show commercial potential as antioxidants, antimicrobials, preservatives in food cosmetic applications, technochemical products, pharmaceuticals. Storing before the conversion process leads to substantial losses extractives In present study, thermal drying for ma...
