  2. 11. Diversity and Ecosystem Functioning : Redundancy and Resilience in Freshwater Bacterial Communities

    Author : Hannes Peter; Lars J. Tranvik; Eva S. Lindström; Silke Langenheder; Nelson G. Hairston; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functioning; bacteria; fresh water; biofilms; multifunctionality; ecological networks; perturbation; fragility; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Abstract : Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. READ MORE

  4. 12. Diversity, dynamics and deficits : the role of social networks for the health of aging populations in Indonesia

    Author : Julia Schröders; Miguel San Sebastian; Maria Nilsson; Fatwa Sari Tetra Dewi; Mark Nichter; Andreas Motel-Klingebiel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; social networks; loneliness; aging; older adult health; noncommunicable diseases; disablement processes; healthcare utilization; elderly care; mixed-methods; causal inference; Indonesia;

    Abstract : Background: This thesis takes as a predicate that humans are social animals and as such, that their social networks and health are intrinsically connected. A guiding heuristic of this thesis was the Berkman model which conceptualizes how social networks impact health. READ MORE

  5. 13. Ecological systems in space: From islands to contiguous landscapes

    Author : Ankit Vikrant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ecosystem stability; metacommunity; Metapopulation; community assembly; species area relationships; complex ecological systems;

    Abstract : Dispersal and interaction networks underlie many ecological systems, often dictating spatio-temporal dynamics as well as emergent patterns. Dispersal has implications for establishment for distinct subpopulations of individual species as well as for the emergence of universal spatial patterns and varied community level structures.

  6. 14. Advancing Resilience Practice : Bridging social-ecological resilience theory and sustainable development practice

    Author : My M. Sellberg; Garry D. Peterson; Albert V. Norström; Sara Borgström; Dirk Roux; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex adaptive systems; Local and regional planning; Resilience thinking; Social-ecological systems; Transdisciplinarity; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : This thesis investigates the application of resilience thinking in different real-world settings and research-practice interfaces, for example in the context of natural resource management, local government planning and food systems. The number of cases of resilience practice are growing, including resilience assessments, planning and action, but there are still few scientific studies and even less synthesis across cases.

  7. 15. Negotiating social-ecological fit through knowledge practice

    Author : Simon West; Lisen Schultz; Emily Boyd; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Knowledge practice; adaptive governance; adaptive management; social-ecological systems; problem of fit; performative; narrative; Natural Resources Management; naturresurshushållning;

    Abstract : Adaptive governance and management (AG and AM) have been proposed to address the “problem of fit” between ecosystems and governance systems. AG and AM are intended to reconfigure the relations between knowledge and action through, for instance, experimentation, collaboration and monitoring, to enhance social-ecological feedbacks. READ MORE
