Abstract

Air pollution induced changes in pine needle chemistry were observed at sample sites in the surroundings of the Pechenganikel smelter. Close to the smelter, elevated concentrations of Ni, Cu and S were found (Ni: 0.7-1 mmol/kg, CU: 0.4-0.5, and S 40-60 mmol/kg) Close to the pollution source needles were enriched in Ni and Cu by needle age. Correlation and principal component analyses show that changes in the element composition of pine needles depended on air pollution and on natural factors as well. The contribution from air pollution increased with needle age. Besides direct input of pollutants from atmosphere, soil contamination and nutritional disturbance contributed significantly to the observed changes.

– Climate change impacts on mountain birch ecosystems

Abstract

Direct and indirect effects of increased CO2 level on the mountain birch ecosystem are reviewed and evaluated, and supplemented with some case studies on mountain birch (Betula pubescens) based on field experiments at different altitudes and greenhouse experiments at elevated CO2 and winter temperature level. These studies have shown that large differences exist in responses on climate change between mountain birch populations, and that these differences may be related to the climate at their habitat.

– Knots and resin pockets in spruce timber evaluated by factor analysis

Abstract

Sawmill recovery might be improved by pre-conversion sorting of logs to obtain more homogenous timber quality suitable for specified products. To enhance the knowledge of factors influencing timber quality, 670 spruce trees from 11 mature stands were observed during harvesting and timber processing. By means of factor analysis several knot and resin pocket properties were reduced to two principal components, one representing the knots and another for resin pockets. The number of independent variables are not easily reduced, leaving a possibility of applying several of the characteristics of the logs, the trees and of the stands in finding an efficient log sorting algorithm.
