  1. 1. Impact of Physical Object on Scaring of geese : with an agroecological approach towards the issue of geese as a pest in agriculture

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Elias Kvarnbäck; [2021]
    Nyckelord :geese; barnacle goose; greylag goose; large grazing birds; agroecological practices; flight initiation distance;

    Sammanfattning : The interactions and conflicts between geese and agricultural interests have risen in the last decades in Sweden. A range of measures are used by humans to disturb and scare geese with the goal to counteract crop damage. The hypothesis of this master thesis is that proximity to physical objects taller than 70 cm above the ground, e.g. LÄS MER

  3. 2. Val av uppehållsplats hos betande gäss under häckning i jordbrukslandskapet vid sjön Tåkern : betydelsen av avstånd till vatten, träd, vägar och bebyggelse

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Filip Svensson; [2020]
    Nyckelord :goose; Tåkern; field; nesting; grazing; buildings; trees; water;

    Sammanfattning : There are a number of species of geese in Sweden that can be found in large flocks during spring migration, but are also relatively numerous during breeding. The accumulation of geese can cause damage to growing crops, something that costs farmers and the state a large amount annually. LÄS MER

  4. 3. Methane flux from Carex ramenskii on coastal meadows and grazing lawns in western Alaska

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

    Författare :Kaj Lynöe; [2017]
    Nyckelord :Arctic wetlands; Greenhouse gases; CH4 emission; Plant mediated gas release; Geese grazing;

    Sammanfattning : In this study we determined the magnitude of plant mediated CH4 emission (flux) in two vegetation types of Carex ramenskii. The objectives of this paper were to quantify the proportion of CH4 emissions from plant mediated flux and the total flux (plant and soil). LÄS MER

  5. 4. Greylag geese (Anser anser) : crop selection and spatial distribution around Sörfjärden, Södermanland

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Carina Tennfors; [2013]
    Nyckelord :Anser anser; accommodation field; compositional analysis; crop damage; dietary preferences; diversionary field; Greylag geese; wildlife conflict;

    Sammanfattning : A rapid population growth in Greylag geese (Anser anser) has led to a conflict between geese and farmers due to the foraging geese in agricultural fields which causes damage to crops by trampling and grazing. Culling cannot always be used as a management tool due to protection of the species and temporal restrictions of hunting seasons. LÄS MER

  7. 5. Grazing in the Arctic : can it mitigate the impacts of climate change? : case study: Zackenberg, northeast Greenland

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

    Författare :Caroline Jonsson; [2012]
    Nyckelord :Arctic; climate change; warming; grazing; ecosystem responses; muskox; herbivores; grazing optimization hypothesis; CO₂-fluxes; Greenland; Zackenberg; Earth and Environmental Sciences;

    Sammanfattning : Climate change has affected ecosystem structure and composition in the Arctic during the last few decades. Researchers have observed a greening trend as the active layer depth is increasing due to rising air- and soil temperatures. LÄS MER
