1. Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value.

2. Effects of shade and humus fertility on boreal forest tree seedling growth, competition and mycorrhizal colonisation
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : In boreal forest ecosystems, growth of tree seedlings is limited by resources both aboveground (through shading) and belowground (through nutrient limitation), and the ability to tolerate or avoid these conditions is important in determining the relative performance of different tree species. Two of the means to compete for these resources, are through increasing stem-elongation to escape shading by neighbours (shade avoidance), and through mycorrhizal symbiosis that may increase the nutrient- and water up-take.
