  1. 1. Influence of structural complexity of the Rumperöd forest on evapotranspiration

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Madeleine Durdek; [2023]
    Nyckelord :Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

    Sammanfattning : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. LÄS MER

  3. 2. Betesmönster hos älg (Alces alces) vintertid i fjällnära skog : En studie av födoval i relation till trädslagssammansättning och habitat

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Ella Hambeson; [2023]
    Nyckelord :Food choice; Alces alces; forested mountainous terrain; winter diet; selection; Betesval; Alces alces; fjällnära skog; vinterföda; selektion;

    Sammanfattning : Browsing patterns in large herbivorous mammals are complex and decisions regarding food items occur at different levels depending on internal or external factors such as energy requirements and available food sources. A broader understanding of the behavior of animals living in habitats of economic interests for humans enables human exploitation with as little impact as possible on the animals' habitats. LÄS MER

  4. 3. Minskning av palsmyrar som resultat av klimatförändringar i norra Sverige mellan 1960–2020

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :My Apelkvist; [2023]
    Nyckelord :palsmyrar; palsar; norra Sverige; carbon feedback; klimatförändringar;

    Sammanfattning : The climate is changing at a rapid rate. This causes both an increase in temperature and precipitation in the northern high latitudes. Subarctic peatlands contain 30% of the carbon storage in the northern permafrost zone. LÄS MER

  5. 4. Aluminum levels in the O-horizon of soils near Sundsvall, Sweden : Are levels of Al elevated due to smelter emission?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mattias Sundin; [2023]
    Nyckelord :Aluminium; Smelter emissions; O-horizon; Al concentration; Scots’ pine needles;

    Sammanfattning : Aluminum (Al) is a potentially toxic element for humans, animals, and plants. Al emitted from smelter plants is one source of Al that may be responsible for increased exposure to humans and the environment. LÄS MER

  7. 5. Heterobasidion spp presence in young pine plantations in southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Sarah Louise Gore; [2023]
    Nyckelord :Heterobasidion; Scots pine; Pinus Sylvestris; Sweden;

    Sammanfattning : Heterobasidion species cause great economic loss the forest industry in the northern hemisphere. The spread of infection takes two forms, the first is an airborne infection and the second is a vegetative infection from infected root to healthy root. Much research has been done concerning the Heterobasidion pathogen. LÄS MER
