  1. 1. Ecosystem processes and biodiversity : theoretical studies and experiments with an aquatic model ecosystem

    Författare :Jon Norberg; Michael L Pace; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Systems Ecology; systemekologi;

    Sammanfattning : Today, human enterprise has implications for all of nature, from the well being of the smallest organism, to the alteration of global biogeochemical cycles. To understand how major ecosystem processes are affected by environmental changes and decreasing biodiversity is crucial as many of natures services depend of such processes. LÄS MER

  2. 2. A network perspective on ecosystems, societies and natural resource management

    Författare :Örjan Bodin; Jon Norberg; Steve Lansing; Stockholms universitet; []
    Nyckelord :network; seed dispersal; pollination; natural resource management; lemur catta; social networks; landscape fragmentation; Madagascar; East Africa; fisheries; resilience; co-management; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis employs a network perspective in studying ecosystems and natural resource management. It explores the structural characteristics of social and/or ecological networks and their implications on societies’ and ecosystems’ ability to adapt to change and to cope with disturbances while still maintaining essential functions and structures (i.

  3. 3. Learning-by-modeling : Novel Computational Approaches for Exploring the Dynamics of Learning and Self-governance in Social-ecological Systems

    Författare :Emilie Lindkvist; Maja Schlüter; Jon Norberg; Örjan Ekeberg; James Dyke; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; SOCIAL SCIENCES; Complex adaptive systems; Renewable resources; Adaptive management; Small-scale fisheries; Artificial intelligence; Reinforcement learning; Agent-based modeling; agent-baserade modeller; artificiell intelligens; social-ekologiska system; komplexa adaptiva system; förnyelsebara naturresurser; adaptiv förvaltning; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : As a consequence of global environmental change, sustainable management and governance of natural resources face critical challenges, such as dealing with non-linear dynamics, increased resource variability, and uncertainty. This thesis seeks to address some of these challenges by using simulation models. LÄS MER

  4. 4. Function follows Form : Trait-based approaches to climate change effects on wetland vegetation and functioning

    Författare :Helen Moor; Jon Norberg; Andrew Gonzalez; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Functional traits; Plant community ecology; Trait distributions; Wetlands; Ecosystem functioning; Ecosystem Services; Climate change; Dispersal; Metacommunity modelling; Natural Resources Management; naturresurshushållning;

    Sammanfattning : Climate change and habitat fragmentation are altering the structure and functioning of plant communities world-wide. Understanding how, why and with what consequences are major challenges of ecology today. Trait-based approaches focus on functional rather than taxonomic identity to facilitate process-based explanation and prediction. LÄS MER

  5. 5. Social learning in the Anthropocene : Governance of natural resources in human dominated systems

    Författare :Björn Nykvist; Jon Norberg; Marianne Krasny; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; social learning; multi-level governance; resilience; adaptability; natural resource management; institutions; policy making; impact assessments; Natural Resources Management; naturresurshushållning;

    Sammanfattning : We live in the Anthropocene – an age where humans dominate natural systems – and there is ample evidence that our current practices degrade the capacity of natural systems to provide us with natural resources. How we, as humans, organize and learn, in communities and among state and other societal actors, constitute a decisive factor for both local management of natural resources and the functioning of the planet Earth.
