    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; ground thermal properties; palsas; permafrost degradation; peat porosity; Sweden; vegetation.; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

    Abstract : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. READ MORE

  4. 7. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

    Author : Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

    Abstract : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. READ MORE

  5. 8. Responses of peatland vegetation to enhanced nitrogen
