  1. 16. Exploring the impact of Formica exsecta ants on soil properties above the tree line in northern Sweden

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

    Författare :Filip Pekkari Juto; [2023]
    Nyckelord :Formica exsecta; ant mounds; soil properties; organic matter content; tundra;

    Sammanfattning : Ants are considered ecosystem engineers due to their effect on the soil properties and their ability to alter the flow of energy and nutrients. Many studies have focused on ants in boreal forests,but few have focused on the ant’s effect on the tundra. LÄS MER

  3. 17. LoRa Based Moisture Sensing System

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Rasha Badran; [2023]
    Nyckelord :LoRa; moisture sensor; capacitive sensor;

    Sammanfattning : Water is an important parameter for crop growth, and the information about the moisture content in soil at different depths is very useful for farmers to determine the best time to water the soil and to irrigate farmland so as to maximize their yield. This thesis project aims to develop a prototype of a multi-depth moisture sensor probe that is part of a large sensing system used in agriculture. LÄS MER

  4. 18. Värmereducerande åtgärder för urbana mikroklimat

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Alice Ljungdahl; Ida Grundh; [2023]
    Nyckelord :klimatförändringar; värmeböljor; värmeöar; värmeöeffekt; klimatanpassning; temperaturreglering; värmereducerande åtgärder; värmereducering; mikroklimat; vegetation; skugga;

    Sammanfattning : Det står klart att rådande klimatförändringar har lett och kommer i framtiden att leda till ökade temperaturer samt fler och längre perioder av värmeböljor. Ökade temperaturer i kombination med värmeöeffekter medför att urbana miljöer är särskilt utsatta och människor som väljer att bosätta sig på sådana platser riskerar allvarliga konsekvenser när det gäller hälsa och välbefinnande.

  5. 19. Forest regeneration and edge effects : an ecophysiological analysis after gap-cutting

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

    Författare :Tyra Tornberg; [2023]
    Nyckelord :Regeneration; Edge effects; Edge zone; Continuous cover forestry; Gap-cutting; Isotope analysis; 15N; Nitrogen; Carbon;

    Sammanfattning : As continuous cover forestry is an ongoing topic in todays forest debate, questions are raised about eventual issues connected to the management. It is known that seedling performance can be poor near the edge of harvested areas, and around retained trees. This is a critical issue in transitioning toward continuous cover forestry. LÄS MER

  7. 20. Investigating the response of terrestrial evapotranspiration to droughts in Africa : A combined remote sensing and modeling approach

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Yang Foo; [2023]
    Nyckelord :earth observation; terrestrial evapotranspiration; drought; vegetation-climate interactions;

    Sammanfattning : Climate change is posing a significant threat to terrestrial ecosystems worldwide, in part due to the more frequent occurrence of extreme climatic events such as droughts. While the importance of drought impacts on vegetation has been widely recognized, the time-dependent characteristics of drought-induced response remain insufficiently understood. LÄS MER
