  1. 21. Nurturing resilience in social-ecological systems : Lessons learned from bridging organizations

    Författare :Lisen Schultz; Carl Folke; Ryan Plummer; Stockholms universitet; []
    Nyckelord :adaptive co-management; social-ecological resilience; local stewards; bridging organizations; learning; participation; Kristianstads Vattenrike; Biosphere Reserves; sustainable development; biodiversity conservation; ecosystem management; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Sammanfattning : In an increasingly complex, rapidly changing world, the capacity to cope with, adapt to, and shape change is vital. This thesis investigates how natural resource management can be organized and practiced to nurture this capacity, referred to as resilience, in social-ecological systems. LÄS MER

  3. 22. Grassland restoration : Connectivity, plant community change and cows

    Författare :Rozália E. Kapás; Sara Cousins; Adam Kimberley; Lars A. Brudvig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; biodiversity; colonization; connectivity; dispersal; distance to species pool; diversity; grassland restoration; grassland specialist species; grazing livestock; habitat availability; plant community composition; restoration; semi-natural grassland; species richness; naturgeografi; Physical Geography;

    Sammanfattning : The ecological significance of semi-natural grasslands is high because these habitats provide a home for a diverse flora and fauna and support a range of associated ecosystem services. Due to large-scale land-use changes the extent of grassland habitat has declined. LÄS MER

  4. 23. Plant-seed predator interactions – ecological and evolutionary aspects

    Författare :Hannah Östergård; Johan Ehrlén; Peter Hambäck; William Kunin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apparent competition; community context; fruit abortion; defence; host range; monophagous; offence; oligophagous; plant-animal interactions; pre-dispersal seed predation; selection; spatio-temporal variation; Biology; Biologi; Plant Ecology; växtekologi;

    Sammanfattning : Plant-animal interactions are affected by both abundance and distribution of interacting species and the community context in which they occur. However, the relative importance of these factors is poorly known. LÄS MER

  5. 24. Meaning and Action in Sustainability Science : Interpretive approaches for social-ecological systems research

    Författare :Simon West; Lisen Schultz; Lorrae van Kerkhoff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meaning; interpretive; social-ecological system; complexity; science-policy interface; transformation; sustainability science methodology; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Social-ecological systems research is interventionist by nature. As a subset of sustainability science, social-ecological systems research aims to generate knowledge and introduce concepts that will bring about transformation. Yet scientific concepts diverge in innumerable ways when they are put to work in the world. LÄS MER

  7. 25. Bacterioplankton population dynamics in a changing ocean

    Författare :Markus V. Lindh; Jarone Pinhassi; Pierre Galand; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; ecology; bacterioplankton; community composition; diversity; seasonality; biogeography; bimodal; metapopulation; community functioning; climate change; environmental disturbance;

    Sammanfattning : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.
