  1. 1. Carbon stocks and fluxes in a young Siberian larch (Larix sibirica) plantation in Iceland

    Author : Brynhildur Bjarnadottir; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interannual variability; carbon balance; Larix sibirica; afforestation; stock-change method; carbon sequestration; eddy covariance; biomass functions;

    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.

  3. 3. Treeline dynamics in short and long term perspectives : observational and historical evidence from the southern Swedish Scandes

    Author : Lisa Öberg; Bengt-Gunnar Jonsson; Leif Kullman; Aage Paus; Mittuniversitetet; []
    Keywords : Betula pubescens ssp. czerepanovii; Picea abies; Pinus sylvestris; Larix sibirica; climate; Betula pubescens ssp. czerepanovii; Picea abies; Pinus sylvestris; Larix sibirica;

    Abstract : Treelines in high-mountain regions are constrained by heat deficiency, although the working mechanisms are still not entirely understood. Observational and paleoecological studies on treeline performance may contribute to increased understanding of the treeline phenomenon in general. READ MORE

  4. 4. Genetic variation in frost tolerance, juvenile growth and timber production in Russian larches (Larix Mill.) : implications for use in Sweden

    Author : Lars Karlman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    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.

  5. 5. Impact of Heterobasidion spp. root rot in conifer trees and assessment of stump treatment : with emphasis on Picea abies, Pinus sylvestris and Larix × eurolepis

    Author : Liying Wang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In the thesis four studies were conducted to understand the impact of Heterobasidion spp. on Picea abies, Pinus sylvestris, and Larix × eurolepis in southern Sweden, and the efficacy of stump treatment against infection in order to economically assess control measures. The ability of secondary spread of H. READ MORE
