  1. 1. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aida Esmailzadeh Davani; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Permafrost; CH4 flux; CO2 flux; Abisko; Wetlands; Earth and Environmental Sciences;

    Abstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE

  3. 2. Time series analysis of ground frost conditions at Abisko, sub-Arctic Sweden, 1985-2010

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anja Schmidt; [2012]
    Keywords : marktemperatur; subarktiska Sverige; Abisko forskningstation; frost cykler; snötäcke; lufttemperatur; Ground temperatures; subarctic Sweden; Abisko research station; frost cycle; snow cover; air temperature;

    Abstract : Observed climatic change may result in modification of the ground thermal regime.The causes of shallow ground temperature variability, however, are not well documented. READ MORE

  4. 3. Variation in protein precipitation and phenolic content within and among species across an elevational gradient in subarctic Sweden

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

    Author : Elin Olofsson; [2010]
    Keywords : Phenolic compounds; Protein complexation; Elevational gradient; Subarctic; Fertility gradient;

    Abstract : This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow.

  5. 4. Degrading palsa mires in northern Europe : changing vegetation in an altering climate and its potential impact on greenhouse gas fluxes

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Karlgård; [2008]
    Keywords : geography; physical geography; palsa mires; northern Europe; greenhouse gas fluxes; Earth and Environmental Sciences;

    Abstract : The on-going global warming is projected to have large impacts on the arctic and subarctic environment. Especially vulnerable are ecosystems with narrow climatic envelopes and with small possibilities of adaptation. An example of this is the palsa mires, subarctic mire complexes with patches of permafrost. READ MORE
