Tree-Ring Growth Trends of Abies alba Mill: Possible Adaptations to Climate Change in Marginal Populations of Central Italy
A dendroclimatic analysis was used to assess the climate-growth relationships of Abies alba Mill. over the last century in marginal populations of Central Italy. Tree-ring cores were collected in five mixed silver fir forests at low and high-elevation sites of the Apennines range in Tuscany and Marches. Regular and moving correlations functions were applied to tree-ring width series and monthly...
متن کاملFoliar and cortex oleoresin variability of silver fir (Abies alba Mill.) in Albania.
Terpene composition of needle and cortical oleoresin from lateral shoots were analyzed by GC/MS for four Silver fir (Abies alba Mill.) populations scattered in natural species range in Albania. More than sixty compounds were detected in the needle oleoresin, which was characterized by a high content of alpha-pinene, camphene, beta-pinene, limonene and bornyl acetate. Three monoterpenes, alpha-p...
متن کاملEstimation of Tree Biomass at Individual tree, Sample plot and Hybrid Level using Drone Images
Two-dimensional image conversion algorithms to 3D data create the hope that the structural properties of trees can be extracted through these images. In this study, the accuracy of biomass estimation in tree, plot, and hybrid levels using UAVs images was investigated. In 34.8 ha of Sisangan Forest Park, using a quadcopter, 854 images from an altitude of 100 meters above ground were acquired. SF...
متن کاملEfectos del hongo patógeno Melampsorella caryophyllacearum Schroet. sobre el crecimiento radial de Abies alba Mill
Effects of the pathogenic fungus Melampsorella caryophyllacearum on radial growth of Abies alba Long-term damages caused by fungi on tree radial-growth and its interaction with climate have been little studied. The incidence and the severity of damage caused by the pathogenic fungus Melampsorella caryophyllacearum on Abies alba in three plots sampled in the Irati forest (Western Pyrenees, Navar...
متن کاملAboveground Tree Biomass for Pinus ponderosa in Northeastern California
Forest managers need accurate biomass equations to plan thinning for fuel reduction or energy production. Estimates of carbon sequestration also rely upon such equations. The current allometric equations for ponderosa pine (Pinus ponderosa) commonly employed for California forests were developed elsewhere, and are often applied without consideration potential for spatial or temporal variability...
