Eucalyptus globulus. Impregnability in relation with plantation and crop
1992 - IRG/WP 92-2402
Eucalyptus globulus Lasill is currently classified in Pr EN 350 on the basis of the characteristics of the first log. In practice, there are usually several following crops of branches developped on each stump in plantations. Up to a diameter of 8 cm, round wood of 2nd crop and further crops present a maximum of sapwood and characteristics which differ significantly from the basic classification a...
Estimates of wood-consumption rates by termites
1983 - IRG/WP 1201
Effects of 2 components; termite-biomass and experiment duration on estimates of wood-consumption rates (mg wood/g termite/day), were examined. Three models; (1) no mortality, (2) linear mortality and (3) nonlinear mortality were used to calculate mean standing-crop biomass of termites. Model (1) predicted a significantly lower wood-consumption rate than those based on models (2) and (3). No signi...
