  1. 21. Diversity of soil microbial communities: In the perspective of targeting functional genes

    Författare :Lokeshwaran Manoharan; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil; metagenomics; sequence capture; microbial communities; functional diversity; taxonomic diversity;

    Sammanfattning : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. LÄS MER

  3. 22. Linking functional traits and cultural ecosystem services in urban areas through human preferences

    Författare :Julie Goodness; Erik Andersson; Thomas Elmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Functional traits; ecosystem services; cultural ecosystem services; urban; cities; human perception; preferences; ecosystem management; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Urban areas are now the daily lived experience for the majority of the world’s people, and it is therefore important to explore what kind of ecological communities and corresponding ecosystem functions and services are being generated in these environments. Urban areas are shaped by a variety of factors, but arguably one of the most influential is that of people, in terms of how their preferences and active selective choices for biota play out in the landscape.

  4. 23. Biodiversity and green infrastructure in urban landscapes

    Författare :Ulf G. Sandström; Per Angelstam; Abdul Khakee; Kjell Nilsson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biologi; Birds in cities; Communication between sciences; Conservation planning; Landscape ecology; Swedish green planning; Urban green space; Urban planning; Urban vegetation; Biologi med ekologisk inriktning; Biology; Biologi; Biologi med ekologisk inriktning;

    Sammanfattning : In this thesis, I evaluate the extent to which biodiversity is affected, and taken into consideration by, urban planning. Based on landscape ecology, I apply an interdisciplinary approach. LÄS MER

  5. 24. Effects of created habitats on farmland biodiversity

    Författare :Annelie Jönsson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agricultural intensification; brown hare; common pheasant; farming intensity; granivorous passerines; grey partridge; habitat creation; landscape heterogeneity; pollinators;

    Sammanfattning : Agricultural intensification has caused severe declines among biodiversity in European farmland over the last half century. The transformation of the agricultural landscape has led to reduced availability of key resources such as food, nesting habitat and shelter. LÄS MER

  7. 25. Managing for biodiversity and ecosystem services in a context of farmland abandonment

    Författare :Cibele Queiroz; Regina Lindborg; Henrique M. Pereira; Carl Folke; Joern Fischer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; farmland abandonment; agriculture; biodiversity; species richness; functional diversity; ecosystem services; forest regeneration; conservation views; response diversity; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : In agricultural landscapes around the world, intensification of production and land abandonment are the two main trends impacting biodiversity and ecosystem services. Intensified agriculture is mostly seen as negative for biodiversity but effects of abandonment are controversial among scientists and practitioners. LÄS MER
