    Sammanfattning : Trenden för biologisk mångfald i världen är negativ och skogslevande arter är inget undantag. I denna studie undersöks den tätortsnära, kommunägda skogen Hallaholm i Åtvidaberg, Östergötland. LÄS MER

  3. 32. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

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

    Författare :Julia Iwan; [2021]
    Nyckelord :Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Sammanfattning : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. LÄS MER

  4. 33. Change in surface area of semi-natural grassland in the Osby municipality, Scania and potential consequences for plant diversity

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

    Författare :Katharina Borgström-Lohde; [2021]
    Nyckelord :Land use change; Semi-natural grasslands; Biodiversity; Scania; Historical land use; Earth and Environmental Sciences;

    Sammanfattning : During the past, land use has changed and still is. It has been recognized that land use changes affect biodiversity all over the world. In Sweden semi-natural grasslands are a habitat with high biodiversity. The topic of this thesis is how land use change has affected the habitat of semi-natural grasslands in the area around Osby, Scania. LÄS MER

  5. 34. The effect of restoration of semi-natural grassland on arthropod populations

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

    Författare :Molly Wikingson; [2021]
    Nyckelord :Arthropoda; Conservation; Grasslands; Landscape factors; Restoration success; Species rich communities;

    Sammanfattning : Semi-natural grasslands are valuable ecosystems that have a high biodiversity. Unfortunately, a lot of this biodiversity is being lost as semi-natural grasslands are declining in both size and number. Restoration to reestablish semi-natural grasslands is often done by removing shrubs and trees and planting seeds. LÄS MER

  7. 35. Changes in habitat suitability for three declining Anatidae species saltmarshes on the Mersey estuary, North-West England

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

    Författare :Cecilia Baggini; [2020]
    Nyckelord :Geography; GIS; habitat suitability model; saltmarsh; protected areas; Earth and Environmental Sciences;

    Sammanfattning : Saltmarshes are areas of coastal grassland that are regularly flooded by seawater. They support a large number of resident and migratory bird species, both overwintering and breeding. LÄS MER
