  2. 1. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests

    Author : Kristoffer Hylander; Christer Nilsson; Bengt Gunnar Jonsson; Ellen Macdonald; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; boreal forest; bryophyte; buffer strip; ecological boundary; edge effect; headwater stream; land snail; liverwort; moss; phytometer; riparian forest; substrate; terrestrial gastropod; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. READ MORE

  4. 2. Turbomachinery in Biofuel Production

    Author : Martin Görling; Mats Westermark; Simon Harvey; Bengt Hylander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-Methanol; Biomass; Gasification; Humidification; Hybrid Cycle; SNG; Chemical energy engineering; Kemisk energiteknik;

    Abstract : The aim for this study has been to evaluate the integration potential of turbo-machinery into the production processes of biofuels. The focus has been on bio-fuel produced via biomass gasification; mainly methanol and synthetic natural gas. The research has been divided into two parts; gas and steam turbine applications.

  5. 3. Dispersal of bryophytes across landscapes

    Author : Niklas Lönnell; Kristoffer Hylander; Bengt Gunnar Jonsson; Sebastian Sundberg; Johan Ehrlén; Risto Virtanen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; anemochory; bryophytes; colonization; connectivity; diaspores; dispersal kernel; establishment; spore dispersal; long-distance dispersal; mechanistic model; mosses; realized dispersal; spore release; Lagrangian stochastic model; wind dispersal; Plant Ecology; växtekologi;

    Abstract : Dispersal, especially long-distance dispersal, is an important component in many disciplines within biology. Many species are passively dispersed by wind, not least spore-dispersed organisms.In this thesis I investigated the dispersal capacity of bryophytes by studying the colonization patterns from local scales (100 m) to landscape scales (20 km).
