  1. 11. Carabidocoenoses and Fragments of Forests : exploring the Carabid Landscape

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

    Författare :Simon Heinrich Arns; [2023]
    Nyckelord :biodiversity; Carabidae; carabid diversity; entomology; Fragmentation; Fragstats; habitat fragmentation; habitat Heterogeneity; landscape; landscape ecology; landscape Heterogeneity; pitfall trap; quantifying fragmentation;

    Sammanfattning : Epigeic ground beetles (Coleoptera: Carabidae) were sampled between 2021-06-28 and 2021-07-09 using pitfall traps in the Swedish counties Värmland and Gävleborg. The structural properties of the landscapes surrounding these points were estimated from the Swedish Environmental Protection Agency’s national land cover databases and the Swedish Forest Agency’s data for all formally protected and high conservation value forests using patch-based configurational metrics.

  3. 12. Pollinator communities on a landscape complexity gradient in southern Sweden

    Magister-uppsats, SLU/Dept. of Ecology

    Författare :Hanna Olsson; [2023]
    Nyckelord :pollinator; bumblebee; rough pasture; semi-natural pasture; unimproved grazing; landscape complexity;

    Sammanfattning : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. LÄS MER

  4. 13. Exploring the conditions for a shift to Continuous Cover Forestry in Sweden : a practice-based approach to understanding what enables and challenges forest management practitioners to practice Continuous Cover Forestry

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Filippa Morner; [2023]
    Nyckelord :environmental communication; social practice theory; practice based approach; Continuous Cover Forestry; forest management practices; Swedish forestry;

    Sammanfattning : This thesis investigates the adoption of Continuous Cover Forestry (CCF) in response to mounting environmental concerns stemming from conventional forestry in Sweden. Utilising a social practice-based approach with qualitative interviews and observations of forest managers who engage in CCF “on the ground”, the study uncovers a complex of practices connected to CCF, encompassing policy and regulation, research, advice, services, and forest ownership.

  5. 14. Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece

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

    Författare :Emmanouil Papadakis; [2023]
    Nyckelord :Geography; GIS; Satellite Remote Sensing; Vegetation Indices; Classification; Archaeology; Earth and Environmental Sciences;

    Sammanfattning : During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception of archaeological landscapes and predict past behaviors.

  7. 15. Urban Trees : A case study in central Umeå

    Magister-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Maria Sundelin; [2023]
    Nyckelord :Urban trees; canopy cover; i-Tree Canopy;

    Sammanfattning : Urban trees are crucial to a healthy environment. The benefits range from good air quality to storm water management and public health. The aim of this thesis was to study urban trees in Umeå city. Umeå is in a process of densification and has a vision to increase in population to 200 000 by the year 2050. LÄS MER
