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

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

    Abstract : 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. READ MORE

  2. 2. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

    Author : Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. READ MORE

  3. 3. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs

    Author : Matilda Thyresson; Magnus Nyström; Edward H. Allison; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; fish; food; key ecosystem processes; functional groups; coral reefs; trade; gear; small-scale fisheries; social-ecological systems; Zanzibar; Tanzania; Western Indian Ocean; naturresurshushållning; Natural Resources Management;

    Abstract : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. READ MORE

  4. 4. Learning ecosystem complexity : A study on small-scale fishers’ ecological knowledge generation

    Author : Diana Garavito-Bermúdez; Camilla Thunborg; Cecilia Lundholm; Beatrice Crona; Alan Reid; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; small-scale fishers; informal learning; knowledge generation; systems thinking; ecological knowledge; ecosystem complexity; work practices; emotional bonds to place; sustainable fisheries management; environmental learning; Vättern; Blekinge; Baltic Sea.; pedagogik; Education;

    Abstract : Small-scale fisheries are learning contexts of importance for generating, transferring, and updating ecological knowledge of natural environments through everyday work practices. The rich knowledge fishers have of local ecosystems is the result of the intimate relationship fishing communities have had with their natural environments across generations (see e. READ MORE

  5. 5. Recalling Urban Nature : Linking City People to Ecosystem Services

    Author : Stephan Barthel; Carl Folke; Thomas Elmqvist; Johan Colding; Per Olsson; Susanne Stoll-Kleemann; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Ecosystem service; functional group; resilience; social-ecological system; urban; institution; property right; knowledge; sense-of-place; social-ecological memory; adaptive governance; scale-crossing broker; ecosystem management; Biology; Biologi; Natural Resources Management; naturresurshushållning;

    Abstract : Societal development is dependent on the generation of ecosystem services (ES) to sustain it; however, many ES are degrading. This thesis investigates how social-ecological features behind practices of actor groups shape the generation of ES. READ MORE
