  1. 1. MOUNTAIN ROADS AND THE HOMOGENIZATION OF PLANTS. A study on plant communities and their traits along the elevational gradient.

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

    Författare :Violetta Chernoray; [2022-09-28]
    Nyckelord :anthropogenic disturbance; spatial ecology; Northern Scandes; functional traits; roadsides; beta-diversity.;

    Sammanfattning : Overexploitation, land use, and other anthropogenic disturbances have increased in recent years, and are expected to increase even further. A very common anthropogenic disturbance, that can be seen even as far as in mountain regions, is roads. LÄS MER

  3. 2. Microbial community responses to freeze : thaw cycles in active layer soils of permafrost tundra, Disko Island, Greenland

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Isabelle Gough; [2019]
    Nyckelord :microbial ecology; active layer soils; bacteria; fungi; permafrost system; amplicon-sequencing; QIIME2; FUN-guild; ; greenhouse gas fluxes; fluorogenic enzyme as-says;

    Sammanfattning : Permafrost affected soils are a vast pool of Carbon, storing around 1300Pg below the ground. As a result of climate change, permafrost soils that have been frozen for thousands of years are thawing, causing the ancient organic matter to be metabolised by microorgan-isms. LÄS MER

  4. 3. Biodiversity assessment for coastal fish communities in the Baltic Sea

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Aline Vullioud; [2016]
    Nyckelord :biodiversity; Baltic Sea; coastal fish communities; biodiversity changes; size-class;

    Sammanfattning : Biodiversity becomes of increasing concern in management of marine ecosystems. Measures of biodiversity are numerous and have been largely developed. Biodiversity can be partitioned in different components that indicate, for example, spatial and temporal changes in any communities. LÄS MER

  5. 4. Jaktens betydelse för Södermanlands landskap : Hur viltvård kan påverka variationen av lövträd och buskar

    Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Angelica Wågström; [2013]
    Nyckelord :jakt; viltvård; Södermanland; biologisk mångfald; fragmentering; variation; lövträd; landskapsekologi; miljövetenskap;

    Sammanfattning : The fragmentation and reduction of deciduous forests in Sweden is threatening many species. Particularity worrying is the loss of broad-leaf trees, since a diversity of species is often associated to them. LÄS MER
