  1. 16. 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

  3. 17. Impact of management intensity on the plant diversity and soil carbon of grasslands in different agro-climatic regions of Sweden

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

    Författare :Hugo Blomberg; [2021]
    Nyckelord :plant species richness; pasture; meadow; soil C; subarctic; humid continental; oceanic; ploughing; fertilization; temperate; continental;

    Sammanfattning : Biodiversity loss is a global issue and within the EU and Sweden, funding is available for practices that can enhance biodiversity. Semi-natural grasslands, either cut or grazed, have proven to host a wide range of biodiversity that can serve important eco-system functions. LÄS MER

  4. 18. The effects of livestock grazing on semi-natural grassland communities along an elevational gradient in Norway

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ieva Petrauskaitė; [2020]
    Nyckelord :grazing intensity; elevational gradient; plant communities; species-specific responses; functional group responses; temporal variation;

    Sammanfattning : Moderate livestock grazing is often identified as a useful management tool for sustaining biodiverse grassland communities and has long been practiced in Scandinavian mountains. Despite of a growing number of studies focusing on grazing effects along elevational gradients worldwide, there is still limited knowledge of how grazing intensity varies over time and how it affects plant communities on species and functional group level.

  5. 19. Ekosystemtjänster i gräsmarker

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Anna Pettersson; [2020]
    Nyckelord :gräsmarker; SUPER-G; ekosystemtjänster; biologisk mångfald; matproduktion; rekreation; kolinlagring;

    Sammanfattning : The interest in the importance of grasslands in Europe has been addressed by the EU project SUPER-G, whose objective is to increase the productivity of grasslands while also exploring how these lands contribute to other types of ecosystem services, i.e. various benefits that humans receives from nature.

  7. 20. Historisk hävdtidpunkt i landskapets gräsmarker

    Kandidat-uppsats, SLU/Swedish Biodiversity Centre

    Författare :Marta Åkesson; [2020]
    Nyckelord :gullviva; hävdtidpunkt; historisk markanvändning; gräsmarker; biologisk mångfald; bete; ängar; storskifteskartor;

    Sammanfattning : Denna studie i biologi berör gräsmarkernas historiska hävdtidpunkt och dess betydelse för den viktiga biologiska mångfalden. Under det senaste århundradet har många av de artrika och hävdade gräsmarkerna i Sverige försvunnit till följd av den intensifiering av jordbruket som skett. LÄS MER
