  1. 1. Precipitation variability modulates the terrestrial carbon cycle in Scandinavia

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Ella Ek; [2021]
    Nyckelord :Terrestrial carbon cycle; NDVI; Precipitation variability; EOF analysis; Scandinavia; Terrestra kolcykeln; NDVI; Nederbördsvariation; EOF analys; Skandinavien;

    Sammanfattning : Climate variability and the carbon cycle (C-cycle) are tied together in complex feedback loops and due to these complexities there are still knowledge-gaps of this coupling. However, to make accurate predictions of future climate, profound understanding of the C-cycle and climate variability is essential. LÄS MER

  3. 2. Automatic Detection of Low Passability Terrain Features in the Scandinavian Mountains

    Master-uppsats, KTH/Geodesi och satellitpositionering

    Författare :Fredrik Ahnlén; [2019]
    Nyckelord :Classification; Fuzzy Logic; Fuzzy Inference System; Automatic Mapping; Terrain Features; Land Cover Mapping; Cartography; Shrub; Mire; Stony Ground; Klassificering; Fuzzy Logic; Fuzzy Inference System; Automatisk Kartering; Terrängföremål; Marktäcke; Kartografi; Videsnår; Sankmark; Stenig Mark;

    Sammanfattning : During recent years, much focus have been put on replacing time consuming manual mappingand classification tasks with automatic methods, having minimal human interaction. Now it ispossible to quickly classify land cover and terrain features covering large areas to a digital formatand with a high accuracy. LÄS MER

  4. 3. Early Holocene occurrence of thermophilous trees in the Storulvån valley : a study based on pollen analysis

    L3-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Daniella Andersson; [2008]
    Nyckelord :thermophilous; Storulvån; Holocene; pollen analysis;

    Sammanfattning : Recent studies on vegetation history in the Swedish Scandes have altered the view on deglaciation and patterns of vegetation colonization. It is now suggested that the mountains were deglaciated earlier than previously thought and the climate being warm enough to allow thermophilous tree species to establish further north than generally thought.

  5. 4. The establishment of Norway spruce (Picea abies (L.) Karst.) on two mountains in the Åre area : a follow-up of the macrofossil finds on Mount Åreskutan

    L3-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Lars-Göran Ek; [2004]
    Nyckelord :Pollen; spruce; Holocene; vegetation history;

    Sammanfattning : The general migration model for Norway spruce (Picea abies) suggests that it arrived and established in Sweden along the Bothnian coast about 3500 years ago. Spruce thereafter spread westwards and southwards in Sweden, and it is suggested to have become established in the Scandes mountains about 1300-1600 years ago. LÄS MER

  7. 5. Klimat- och miljöförändringar under holocen i Sylarnaområdet, södra svenska Skanderna, baserat på analys av makrofossil och klyvöppningar

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Sara Lamme; [2000]
    Nyckelord :Holocene; tree-limit variation; Seandes mountains; macrofossil; stomata; AMS 14C-measurements; Earth and Environmental Sciences;

    Sammanfattning : A sediment sequence from Lake Spåime, situated at 887 m a.s.l. in the Sylarna area, southern Scandes, mid-central Sweden, was investigated with respect to plant macrofossil, stomata and total organic carbon analysis. LÄS MER
