  1. 16. Epixylic, forest-interior bryophytes in young stands : importance of local environmental variables, propagule sources, and distance to bordering woodland key habitats

    University essay from SLU/Dept. of Ecology

    Author : Simon Hultby; [2011]
    Keywords : CWD; FWD; stump; stump harvest; Anastrophyllum hellerianum; lichen;

    Abstract : The reduction of coarse, dead wood is considered to be the biggest threat to flora and faunain boreal forests. Extensive harvest of logging residues would increase this reduction evenmore. However, the role of dead wood created at final felling for boreal, epixylic species isstill largely unclear. READ MORE

  2. 17. Epixylic lichens and bryophytes in young managed forests : substrate preferences and amounts of dead wood

    University essay from SLU/Dept. of Ecology

    Author : Helena Magnusson; [2010]
    Keywords : dead wood; lichens ; bryophytes; fine woody debris; stump harvest; coarse woody debris; species occurrence;

    Abstract : Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. READ MORE

  3. 18. Effects of site quality and surrounding landscape on bryophytes and brackets on logs in woodland key habitats

    University essay from Institutionen för fysik, kemi och biologi

    Author : Nina Dahlerup; [2010]
    Keywords : WKH; dead wood; species richness; saproxylic species; scale; red-listed species;

    Abstract : A tool for management and conservation of valuable forests in Sweden are WKH:s. In this study WKH:s different in size, connectivity, amount of dead wood and quality of logs were investigated for species richness of bryophytes and brackets on coniferous logs. READ MORE

  4. 19. Distribution and nitrogen fixation of terricolous lichens in a boreal forest fire chronosequence

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

    Author : Aron Sandling; [2010]
    Keywords : Succession; Fire chronosequence; Nitrogen fixation; Boreal forests; Lichens; Peltigera aphthosa; Nephroma arcticum;

    Abstract : 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. 20. Död ved i gallrad skog och nyckelbiotoper : en jämförelse av habitatkvaliteter för vedlevande lavar och mossor

    University essay from SLU/Dept. of Ecology

    Author : Ellen Salomonsson; [2009]
    Keywords : död ved; lavar; mossor; FWD; CWD; stubbar; nyckelbiotop; gallrad skog;

    Abstract : A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. READ MORE
