  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. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

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

    Författare :Malin Ahlbäck; [2020]
    Nyckelord :Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Sammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER

  5. 19. 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.

  7. 20. 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.
