  1. 11. Hydrological control of plant species composition and distribution in Dal River alluvial meadows

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

    Författare :Matouš Jimel; [2023]
    Nyckelord :Riparian zone; Alluvial meadows; Riparian vegetation; Regulated river; Flooding;

    Sammanfattning : Northern boreal alluvial meadows are ecologically significant semi-natural ecosystems within the riparian zone. The effects of disturbance like flooding, grazing, and mowing have historically maintained high nutrient turnover and succession disruption that led to high biodiversity, leading to their inclusion in the Natura 2000 network.

  3. 12. Åskvädret 2 : Förstärka det befintliga för framtida gemensamma rum

    Master-uppsats, Konstfack/Inredningsarkitektur & Möbeldesign

    Författare :Johanna Moe; [2022]
    Nyckelord :Community Centre; adaptive reuse; property development; addition; support structures; reuse; community; democracy; kulturhus; återbruk; fastighetsutveckling; tillägg; stöd; gemenskap; demokrati;

    Sammanfattning : 2018 startade några boende i Björkhagen söder om Stockholm föreningen ”Björkhagens Hjärta”. De saknade gemensamma lokaler och ville arbeta för ett kulturhus i den nedlagda och rivningshotade panncentralen, fastigheten ”Åskvädret 2” på Halmstadsvägen/ Hässleholmvägen. LÄS MER

  4. 13. Mapping Fire Salamander (Salamandra salamandra) Habitat Suitability in Baden-Württemberg with Multi-Temporal Sentinel-1 and Sentinel-2 Imagery

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

    Författare :Andreas Eriksson; [2022]
    Nyckelord :Geography; GIS; Habitat Suitability; Remote Sensing; Image Classification; Earth and Environmental Sciences;

    Sammanfattning : Remote sensing image classification is used in land cover, forest type and tree species classifications but rarely considered for habitat suitability modelling of animal and plant species. It is instead common that land cover products derived from remote sensing data are used in these modelling problems, even though satellite imagery can provide more detailed information. LÄS MER

  5. 14. What has happened on Swedish mires? The effects of drainage on vegetation changes over recent decades

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Anna Ljungqvist; [2022]
    Nyckelord :peatlands; mires; bogs; fens; sweden; vegetation; plant ecology; time trend; data; nfi; nils; climate change; global warming; mosses; sphagnum; afforestation; trees; wetland; presence; coverage; drainage; ditch;

    Sammanfattning : As they are not only the home of many threatened species, but also one of the main actors in the global carbon cycle, peatlands are highly valuable ecosystems. Human disturbance, in particular drainage for forestry and agriculture, has substantially changed the state of the world’s peatlands and will continue to do so. LÄS MER

  7. 15. POLLINATION ECOLOGY OF PEDICULARIS SCEPTRUM-CAROLINUM : An investigation on flower visits in northern Sweden

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

    Författare :Johan Närvä; [2022]
    Nyckelord :Pedicularis sceptrum-carolinum; Pollination; Pollination ecology; Pollinators; Bumblebees.;

    Sammanfattning : Pedicularis sceptrum-carolinum is threatened in much of its geographic range. As it reproduces vegetatively only to a limited extent, the species relies heavily on pollinators for reproduction. One aspect often overlooked in restoration efforts is the pollination ecology of flowering plants and their pollinators. LÄS MER
