  1. 1. 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 :NATURVETENSKAP; NATURAL SCIENCES; Functional traits; Plant community ecology; Trait distributions; Wetlands; Ecosystem functioning; Ecosystem Services; Climate change; Dispersal; Metacommunity modelling; naturresurshushållning; Natural Resources Management;

    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

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

    Författare :Matilda Thyresson; Magnus Nyström; Edward H. Allison; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

    Författare :Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. LÄS MER

  7. 5. Connections between biodiversity and ecosystem functioning in large-scale natural ecosystems

    Författare :James Hagan; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecology; ecosystem function; ecosystem process;

    Sammanfattning : Billions of years of evolution have given us a planet that supports a remarkable diversity of life. Estimates for the number of Eukaryotic species frequently number in the millions and the Prokaryotes are much more diverse than that. This biodiversity makes up the ecosystems that we, as humans, rely on to sustain almost every aspect of our lives. LÄS MER
