  1. 1. The diversity of moths in a nature reserve in the Northern Cape, South Africa : Variation over time, depending on abiotic factors and differences between areas with different grazing types

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Nellie Jarl; [2023]
    Nyckelord :Moth diversity; grazing effects; land use; biodiversity;

    Sammanfattning : Land use changes globally have significant impacts on flora and fauna. In South Africa, extensive land is used for grazing by both domestic livestock and farmed native grazers. However, the effects of different grazing types on vegetation and fauna remain poorly understood. LÄS MER

  3. 2. ARCTIC PLANT COMMUNITIES RISE WITH TEMPERATURE Plant functional traits as a tool to predict global climate change

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Helena Sundell; [2022-07-06]
    Nyckelord :Arctic warming; plant functional traits; Community Weighted Mean; vegetational changes; global climate change;

    Sammanfattning : Global warming occurs at a rate at least three-fold in the arctic regions compared to the rest of the world. Here, plant community functional traits were assessed in response to experimental warming in three arctic areas of Fennoscandia (Latnajajure, Abisko and Kilpisjärvi). LÄS MER

  4. 3. Monitoring wetland cover changes during the past two decades within the protected areas of the Sudd wetland in South Sudan using MODIS data

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

    Författare :Charlotta Ruuskanen; [2021]
    Nyckelord :Physical Geography and Ecosystem analysis; MODIS; NDVI; Sudd Wetlands; Wetland Cover Classification; White Nile Hydrology; Armed Herder-Pastoralist Conflict analysis; Earth and Environmental Sciences;

    Sammanfattning : The Sudd wetland, situated along the White Nile in the Republic of South Sudan, is recognized internationally for its unique environmental features. The distinctive ecological characteristics have resulted in the creation of numerous nature reserves in efforts to conserve the habitats and ecosystem services provided. LÄS MER

  5. 4. A palaeoecological study of the establishment of beech forest in Söderåsen National Park, southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Maja Damber; [2020]
    Nyckelord :Odensjön; southern Sweden; palaeoecology; pollen; macrofossils; lake sediments; Fagus sylvatica; Earth and Environmental Sciences;

    Sammanfattning : Denna studie fokuserar på en sedimentsekvens som hämtats från Odensjön, i Söderåsens nationalpark i Skåne, södra Sverige. Den undersökta sekvensen, som täcker de översta 86 cm av sedimenten, är unik på grund av dess väldigt tydliga årsvarv, som har möjliggjort en precis datering (Hertzman in prep.). LÄS MER

  7. 5. The Vegetational and Environmental Development of Lina Mire, Gotland from 6900-400 BC

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Nichola Strandberg; [2017]
    Nyckelord :Pollen; Lina Mire; Archaeology; Baltic; Human impacts;

    Sammanfattning : Lina Mire, Gotland, is an area of archaeological significance and has a complex history of shoreline displacement. Archaeologists suspect that Lina Mire was once part of an important inland water system which connected the Littorina Sea with central Gotland. LÄS MER
