  1. 11. Land cover changes in Southern Sweden from the mid-Holocene to present day: insights for ecosystem service assessments

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Robert O'Dwyer; [2019]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Götaland; Landscape Reconstruction Algorithm; Fossil Pollen; Ecosystem Services; Earth and Environmental Sciences;

    Abstract : Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from pollen information.

  3. 12. Att läsa brandspår i skogslandskapet: olika underlag för att förstå naturlandskapets branddynamik

    University essay from SLU/School for Forest Management

    Author : Anders Dahlberg; [2016]
    Keywords : ASIO; brandspårsfrekvens; skogsbrand;

    Abstract : The purpose of this study is to explore different methods to understand the local history of past fire disturbance regimes in a forest management unit. Focusing on the Bergslagen region in south-central Sweden, which has a very long history of forest management, the frequency of occurrence of fire scars on living trees, burned wood, and macroscopic charcoal in the litter layer and in small peat bogs, were studied in landscape strata different with different biophysical characteristics affecting the probability of fire.

  4. 13. Is it possible to reconstruct local pre-sence of pine on bogs during the Ho-locene based on pollen data? : a study based on surface and stratigraphical samples from three bogs in southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Isabelle Timms Eliasson; [2014]
    Keywords : southern Sweden; vegetation cover; bog; Pinus; pollen; Earth and Environmental Sciences;

    Abstract : Horizons rich in subfossil stumps and roots of Scots pine (Pinus sylvestris) are frequently found in stratigraphies of northern European peatlands, providing clear evidence of Holocene periods with favourable conditions for bog-pine growth. The pines could only grow when bog-surface wetness was sufficiently low, and the presence of their remains is therefore a good indicator of past climatic conditions, mainly precipitation. READ MORE

  5. 14. Peat stratigraphical study of hydrological conditions at Stass Mosse, southern Sweden, and the relation to Holocene bog-pine growth

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linda Adamsson; [2013]
    Keywords : tall; mosse; klimatförändringar; palaeoecology; macrofossil analysis; pines; climate change; bog; makrofossilanalys; paleoekologi; Earth and Environmental Sciences;

    Abstract : Sammanfattning: Torvhorisonter med stora mängder subfossila stubbar och rötter av tall (Pinus sylvestris) förekommer ofta i nordeuropeiska torvmossar. De visar att mossarna varit tallbevuxna under delar av Holocen. READ MORE

  6. 15. Dissolved methane dynamics in a subarctic peatland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Zhendong Wu; [2012]
    Keywords : permafrost; pore water; Dissolved CH₄; CH₄ solubility; CH₄ flux; physical geography; peatland; geography; subarctic; Earth and Environmental Sciences;

    Abstract : Popular science: Methane (CH₄) is a colorless, odorless, tasteless gas that can trap heat in the atmosphere. It is believed to be a powerful greenhouse gas. READ MORE
