  1. 1. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

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

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  3. 2. The effect of the COVID-19 lockdown on the spatial ecology of moose in an area with high recreational activity

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Maximilian Dörr; [2024]
    Nyckelord :Moose; Alces alces; habitat selection; tourism; human disturbance; activity; movement; speed; seasons; Covid-19; pandemic;

    Sammanfattning : In diverse landscapes, the coexistence of wildlife habitat requirements and human land use often leads to conflicts, posing challenges for sustainable species management. Recreational activities, especially in sparsely populated areas, frequently disturb wildlife behavior, necessitating a comprehensive assessment of anthropogenic impacts on habitats. LÄS MER

  4. 3. Shifting focus from yields to food supply : an evaluation of the ‘number of people fed per hectare’ indicator at farm and national level

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Ida Ekqvist; [2024]
    Nyckelord :Land use efficiency; Sustainability indicators; Agricultural productivity; Food production;

    Sammanfattning : The challenge of feeding a growing global population while reducing the pressure on climate and ecosystems has gained much attention in research over the last decades. A crucial yet often overlooked aspect in research addressing this complex challenge is the efficiency of food production in meeting nutritional needs within the constraints of global cropland resources.

  5. 4. The Potential to Target Smaller Sized Baltic Herring to Decrease the Dietary Exposure - an Assessment Based on Dioxin Samples from the Southern Baltic

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Sofie Gustafsson; [2024]
    Nyckelord :Dioxin; PCDD Fs; dl-PCBs; Herring; Baltic; Fishery; Technology and Engineering;

    Sammanfattning : PCDD/Fs and dl-PCBs, or more commonly referred to as dioxin and dioxin like substances are compounds present in our surrounding environment. As some congeners of these have been shown to be toxic, they are regulated under the Stockholm Convention. LÄS MER

  7. 5. En hållbarhetsanalys av uppvärmning av konstgräsplaner i Uppsala

    Kandidat-uppsats, SLU/Dept. of Energy and Technology

    Författare :Martina Holma; [2023]
    Nyckelord :konstgräs; konstgräsplan; fotboll; uppvärmning; hållbar utveckling; miljö; uppvärmda konstgräsplaner;

    Sammanfattning : Syftet med detta arbete är att undersöka uppvärmningen av konstgräsplaner i Uppsala kommun ur ett hållbarhetsperspektiv. Bedömningen baseras på data på energiförbrukning, kostnad och bokningar av de berörda konstgräsplanerna. LÄS MER
