  1. 1. 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. 2. Effects of diversified cropping on arthropod communities

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Eira Eksvärd; [2022]
    Nyckelord :carabids; spiders; traits; organic amendments; ley legacy effects;

    Sammanfattning : Även intensiva moderna jordbruk är beroende av ekosystemtjänster som organismer bidrar med såsom biologisk bekämpning av skadedjur. Effekten av biodiversitet på ekosystemprocesser förklaras inte i tillräcklig grad av taxonomisk mångfald, utan beror snarare på mångfalden av funktionella egenskaper bland arterna. LÄS MER

  4. 3. Diversitet hos jordlöpare (Col: Carabidae) i hävdade strandnära gräsmarker

    L3-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :David Isaksson; [2003]
    Nyckelord :jordlöpare; naturbetesmarker; fallfällor; Harpsund; Nötmyran; Pustnäs; agonum dolens; panageus cruxmajor; chlaenius nigricornis;

    Sammanfattning : The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. LÄS MER
