  1. 21. 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

  3. 22. Seabirds as food for thought : An integrative study on seabird ecology and ecosystem services in changing marine systems

    Författare :Martina Kadin; Thorsten Blenckner; Morten Frederiksen; Olof Olsson; Johan Elmberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; seabirds; ecosystem services; social-ecological systems; marine systems; fisheries; foraging ecology; provisioning behaviour; common murre; common guillemot; Uria aalge; Stora Karlsö; Baltic Sea; naturresurshushållning; Natural Resources Management;

    Sammanfattning : The importance of the benefits that humans obtain from the oceans is increasingly recognized, along with the rapid decline in marine resources that threatens these benefits. Studying seabirds – top predators in marine ecosystems, can provide insights about multiple pressures and the state of the oceans. LÄS MER

  4. 23. Social-ecological dynamics of ecosystem service bundles

    Författare :Megan Meacham; Albert V. Norström; Garry D. Peterson; Dagmar Haase; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; multifunctionality; landscape; patterns; cluster; drivers; mapping; trade-offs; synergies; sustainability; land use; landscape management; Sweden; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : The environments in which we live are complex, adapting and evolving in non-linear ways. The ecosystem services produced in landscapes supply resources, support livelihoods and are foundational to human wellbeing. LÄS MER

  5. 24. Land Use, Freshwater Flows and Ecosystem Services in an Era of Global Change

    Författare :Line Gordon; Carl Folke; David Molden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freshwater; green water; ecosystem services; integrated water resources management; food production; land use and land cover change; vulnerability; resilience; hydrological cycle; global change; Australia; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The purpose of this thesis is to analyse interactions between freshwater flows, terrestrial ecosystems and human well-being. Freshwater management and policy has mainly focused on the liquid water part (surface and ground water run off) of the hydrological cycle including aquatic ecosystems. LÄS MER

  7. 25. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats

    Författare :Pia Norling; Nils Kautsky; Tom Ysebaert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; blue mussel; Mytilus spp.; ecosystem engineering; habitat-modifier; diversity; facilitation; ecosystem functioning; ecosystem services and water quality maintenance; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates. These assemblages change the local environment and create unique habitats. LÄS MER
