1. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth
Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

2. Interactions between climate, natural disturbances, and regeneration in boreal and hemi-boreal forests
Abstract : Natural disturbance is an important driving force of community dynamics in many forest types around the globe. Understanding spatial and temporal properties of disturbance events in the present and in the past is important in formulating the nature conservation strategies as well as for the modeling of climate and human impacts on forest vegetation.

3. Carbon stocks and fluxes in a young Siberian larch (Larix sibirica) plantation in Iceland
Abstract : The understanding of how forests function with respect to carbon (C) balance and its interaction with the climate system is a fundamental question in climate change research. Another important question is how large the sink for CO2 is in northern forests and how it varies with forest type, management, stand age and with external factors, such as climate variability.

4. Applications of visible and near infrared spectroscopy for sorting and identification of tree seeds
Abstract : Seeds are the most commonly used regeneration material for reforestation purpose; hence interest in “precision sowing” among nurseries is high due to the high cost of containerized seedling production. In addition, the increased interest in growing hybrid larch in commercial forestry has raised concerns about the purity of hybrid larch seed lots, as there are large proportions of pure parental seeds mixed with hybrid larch seed lots.

5. Genetic variation in frost tolerance, juvenile growth and timber production in Russian larches (Larix Mill.) : implications for use in Sweden
Abstract : Larch (Larix sp Mill.) is an important component in boreal montane and subalpine forests in the northern hemisphere. Macrofossils of larch in the Scandinavian mountains prove the existence of larch in Scandinavia after the last ice age, Siberian or Russian larch is now considered as an indigenous tree species of Sweden.
