  1. 11. Effects of climate on phenology, flowering, and berry production of boreal forest understory plants

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Shakhera Akter Shimu; [2023]
    Nyckelord :Climate change; plant phenology; phenological traits; phenology change; cumulative temperature; phenotypic plasticity; genotypic variation;

    Sammanfattning : Climate is changing faster than it was predicted before and consequently its impact is highly visible on many types of ecosystems globally. Effects of changing climate on forests and the environment are leading to threats for all sorts of ecosystems. LÄS MER

  3. 12. Har signalarter störst förekomst inom eller utanför Dalarnas boreala naturreservat? : En studie om arttätheten av signalarter i Dalarnas barrskogar

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

    Författare :Caroline Ahlgren; [2023]
    Nyckelord :coniferous forest; boreal forests; nature reserve; signal species; indicator species; biodiversity; Barrskog; boreala skogar; naturreservat; signalarter; indikatorarter; biologisk mångfald;

    Sammanfattning : Today, it is well known that biological diversity is decreasing worldwide, and the presence of indicator species can identify areas with high biological diversity. Environments with a high presence of indicator species are important to protect and preserve in the form of, for example, nature reserves as these environments indicate high nature values. LÄS MER

  4. 13. Effects of climate, soil, and forest structure on specific leaf area of understorey foundation plants

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Sashank Khaniya; [2023]
    Nyckelord :Specific leaf area; understorey vegetation; foundation species; forest structure; climate change;

    Sammanfattning : Forest overstorey's interaction with understorey vegetation is a crucial aspect that impacts the biodiversity and resilience of forest ecosystems. Particularly, the influence of the overstorey on the specific leaf area (SLA) in understorey plants remains poorly understood. LÄS MER

  5. 14. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

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

    Författare :Nils Helge Havertz; [2023]
    Nyckelord :Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

    Sammanfattning : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.

  7. 15. Fungal Effects on Tree Growth in a Primary Succession

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

    Författare :August Hedberg; Julian Säflund; [2023]
    Nyckelord :primary succession; succession; ectomycorrhiza; saprotroph; tree growth; Pinus sylvestris; soil fungi;

    Sammanfattning : In the Boreal zone, ectomycorrhiza is the most common mycorrhiza found among trees and helps with nitrogen and nutrient uptake. Most research on mycorrhiza, its effect, and community development are done on secondary succession (succession in an ecosystem after a disturbance) such as after a clearcut. LÄS MER
