  1. 1. Winter wheat exudates : Improving wheats resilience to drought

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

    Författare :Freja Haverland; [2024]
    Nyckelord :drought; PGPR; exudates; agriculture; food security;

    Sammanfattning : Wheat (Triticum aestivum) is a crop that dominates the diets of about 35% of the world's human population. But wheat yields can be severely affected by drought. Therefore, in this experiment, root exudation of winter wheat was compared to find out how exudation changes during drought stress. LÄS MER

  3. 2. Scientists' perception on institutional data sharing support and pressure : Investigating ecologists’ data sharing behavior

    Master-uppsats, Uppsala universitet/Institutionen för ABM

    Författare :Jenny Glashoff; [2023]
    Nyckelord :Data sharing; ecology; theory of planned behavior; semi-structured interviews; Datadelning; ekologi; teorin om planerat beteende; semistrukturerade intervjuer;

    Sammanfattning : Data from underlying research has become increasingly important to scientists and the public in recent decades. As a result, funders and journal publishers have become increasingly demanding that scientists share their data. Universities have also been encouraged to advance their data sharing support units as a result of this development. LÄS MER

  4. 3. HUR FRÄMJAS HÄLSAN I UTEMILJÖER PÅ CAMPUS? : En enkätbaserad fallstudie vid Umeå universitet

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

    Författare :Selma Softic; [2023]
    Nyckelord :green spaces; nature and health; health benefits; social issues; attractiveness; wellbeing; depression; anxiety.;

    Sammanfattning : Urbanization and population growth necessitate an increased presence of green spaces in urban settings to uphold the well-being and health of residents. Outdoor environments with green spaces have shown positive effects on our mental and physical health by reducing stress and enhancing well-being. LÄS MER

  5. 4. Long-term Nitrogen Deposition and Recovery of Epiphytic Lichens : Concealed memory and implications

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

    Författare :Camille Volle; [2022]
    Nyckelord :epiphytic lichens; N deposition; boreal forest; recovery; critical load;

    Sammanfattning : Anthropogenic activities have increased nitrogen (N) emissions. However, higher N deposition is associated with negative fallouts in ecosystems, highlighting the necessity to define its critical load (CLO). Lichens, with their lack of roots, stomata, and cuticles, are helpful air pollution indicators and can be used to establish N CLO. LÄS MER

  7. 5. Reindeer decrease soil carbon stocks and deplete labile soil carbon

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

    Författare :Josua Seitz; [2022]
    Nyckelord :Reindeer; SOC; soils; Finnland; 13C NMR;

    Sammanfattning : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.
