    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Andreea Petronela Spinu; [2018]
    Keywords : dendroecology; disturbance regime; forest history; fire history; regeneration of Pinus sylvestris L.; regeneration of Quercus robur L.; temperate lowland Tilio-Carpinetum forest; mesophication; fire cessation;

    Abstract : In temperate Europe, the ecological importance of fire is poorly understood, especially in the dynamics of forests with high share of broadleaved tree species. The aim of this thesis was to explore the role of fire in a 43-ha mixed-deciduous forest stand in Białowieża Forest, NE Poland. READ MORE

  5. 4. The effect of moisture, litter and stand age on N fixation in the feathermoss, Pleurozium schreberi

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Helena Gustafsson; [2008]
    Keywords : Pleurozium schreberi; Nitrogen fixation; feathermoss; boreal forest; stand age; moisture; litter; cyano bacteria; succession after fire;

    Abstract : The largest known natural input of nitrogen (N) into the boreal forests occurs through biological fixation by cyanobacteria that live in association with the moss Pleurozium schreberi. There is currently limited knowledge about the factors responsible for the variation in N fixation rates, and specifically what factors drive variability between stands. READ MORE
