  1. 1. Trends in mountain birch seed abundance and its relation to temperature and moth abundance: a ten-year study from Swedish Lapland

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Frida Gustafsson; [2023-02-09]
    Nyckelord :Betula pubescens; climate change; seed production; Epirrita autumnata; Operophtera brumata; subarctic ecology; folivory; larval abundance;

    Sammanfattning : Boreal forest is the world’s largest terrestrial biome. Being one of the most ubiquitous and coldtolerant tree species in Sweden, the mountain birch forms a unique deciduous treeline and marks the forest-tundra ecotone. LÄS MER

  3. 2. The implications of heavy fuel oil ban in arctic waters for sustainable arctic shipping

    Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

    Författare :Kaung Thu; [2023-01-23]
    Nyckelord :Arctic region; heavy fuel oil; shipping; Sustainable;

    Sammanfattning : The increased temperature in the polar regions is one of the significant impacts of global warming and consequential climate change. In the Arctic, regional warming leads to the accelerated loss of sea ice caps, which has opened up new international shipping routes. LÄS MER

  4. 3. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sara Rognås; [2023]
    Nyckelord :aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

    Sammanfattning : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. LÄS MER

  5. 4. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

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

    Författare :Alexina Brännlund; [2023]
    Nyckelord :Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Sammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  7. 5. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Albin Andreasson; Noa Lind; [2023]
    Nyckelord :Svalbard; loess soil; XRF; weathering; climate change;

    Sammanfattning : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.
