2. Effects of climate warming on the performance of three boreal tree seedling species in interaction with moss cover and fire history
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Forest regeneration in the form of successful seedling establishment is a key factor for the persistence of a healthy forest ecosystem. Tree seedlings grow in a complex environment shaped by over- and understory and competition for light, nutrients and water. READ MORE

4. Distribution and nitrogen fixation of terricolous lichens in a boreal forest fire chronosequence
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Given that nitrogen (N) is a limiting nutrient in boreal ecosystems, biological N fixation can have a large influence on primary production and other processes in this ecosystem. To date, most studies focused on N fixation in boreal ecosystems have focused on bryophyte-cyanobacteria associations, whereas relatively few studies have investigated the significance of N fixation by lichens.

5. A comparison of protein complexation capacity among six boreal species and the consequences for nitrogen mineralization
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Nitrogen (N) is considered to be the most limiting nutrient for productivity in boreal forests, and the ability of plants to complex protein during decomposition is considered to be an important mechanism by which some plants regulate the N cycle. In this study I investigated whether six boreal plant species differed in their ability to complex proteins. READ MORE
