  1. 6. Fate of organic carbon in a tropical mangrove ecosystem

    Författare :John Machiwa; Michael Risk; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : The aim of this thesis was to study the budget and fluxes of organic carbon in a tropical mangrove forest. Maruhubi forest is located in the Island of Zanzibar, East Africa. Aspects of structure and functions of the ecosystem are investigated. LÄS MER

  3. 7. Changing land cover as a driver of surface water browning

    Författare :Martin Skerlep; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic matter; iron; land cover; browning; afforestation; biogeochemistry; spruce;

    Sammanfattning : Streams, rivers and lakes across wide areas of the Northern hemisphere have been subject to an increase in water color over the last decades. This increase, also known as browning, is a result of rising dissolved organic matter (DOM) and iron (Fe) concentrations in the water. LÄS MER

  4. 8. Towards an integrated ecology through mechanistic modelling of ecosystem structure and functioning

    Författare :Thomas Hickler; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; geomorphology; Physical geography; integrated ecology; plant hydraulic architecture; climate change; CO2 fertilisation effect; biogeography; biogeochemistry; vegetation dynamics; ecosystem modelling;

    Sammanfattning : Plant physiology, population dynamics and the structure and functioning of ecosystems are closely interrelated. However, these processes are often investigated independently within different subdisciplines of ecology. LÄS MER

  5. 9. Dynamic modelling of the forest ecosystem: Incorporation of the phosphorus cycle

    Författare :Lin Yu; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamic modeling; forest ecosystem; phosphorus cycle;

    Sammanfattning : The forest ecosystem provides and regulates many important ecosystem services, such as soil and water protection, timber production, and climate regulation. It has been influenced by changes induced by humans, for example, our increasing demand for timber and bioenergy, the increase in nitrogen (N) deposition and CO2 concentrations due to industrialization, and climate change which has caused an increase in global temperature and extreme events such as storms.

  7. 10. Biogeochemical processes in forest riparian zones : conceptualizing function and heterogeneity in boreal catchments

    Författare :Jose Ledesma; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The area of interaction between terrestrial and aquatic environments, i.e. the riparian zone (RZ), has long been recognized as an important landscape feature from both scientific and management perspectives. Surface water quality is to a great extent regulated by substances exported from RZs. LÄS MER
