  1. 26. Towards the Limits – Climate Change Aspects of Life and Health in Northern Sweden : studies of tularemia and regional experiences of changes in the environment

    Författare :Maria Furberg; Maria Nilsson; Anders Johansson; Lars Weinehall; Peter Friberg; Umeå universitet; []
    Nyckelord :Climate change; public health; Indigenous peoples; Sami; reindeer herding; resilience; tularemia; mixed-methods; infectious disease; seroprevalence; ELISA; outbreak investigation; risk factor; ecology; Francisella tularensis; Epidemiology; epidemiologi; folkhälsa; Public health;

    Sammanfattning : BackgroundIndigenous peoples with traditional lifestyles worldwide are considered particularly vulnerable to climate change effects. Large climate change impacts on the spread of infectious vector-borne diseases are expected as a health outcome. LÄS MER

  3. 27. Flocculation of Allochthonous Dissolved Organic Matter – a Significant Pathway of Sedimentation and Carbon Burial in Lakes

    Författare :Eddie von Wachenfeldt; Lars Tranvik; David Bastviken; John Downing; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flocculation; dissolved organic carbon; allochthonous; carbon sequestration; carbon cycle; boreal lakes; Freshwater ecology; Limnisk ekologi;

    Sammanfattning : Inland waters receive substantial amounts of organic carbon from adjacent watersheds. Only about half of the carbon exported from inland waters reaches the oceans, while the remainder is lost en route. This thesis identifies flocculation as an important and significant fate of carbon in the boreal landscape. LÄS MER

  4. 28. The role of sediments in the carbon cycle of boreal lakes

    Författare :Hannah Elisa Chmiel; Sebastian Sobek; James Cotner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Inland waters are active sites of carbon (C) processing and emitters of carbon dioxide (CO2) and methane (CH4) to the atmosphere. In the boreal zone, where surface waters receive large quantities of organic carbon (OC) from surrounding forests and wetlands, lakes and streams act as strong sources of these greenhouse gases.

  5. 29. Nest-site attendance and foraging ecology of the Northern Fulmar (Fulmarus glacialis) on the Faroe Islands. Is the Northern Fulmar a useful indicator of ecosystem productivity and pollution?

    Författare :Johannis Danielsen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nest-site attendance; foraging ecology; indicator species; Fulmar; Fulmarus glacialis; nocturnal activity; ecosystem productivity; pollution; mesopelagic fish;

    Sammanfattning : The Northern Fulmar (Fulmarus glacialis) is one of the most abundant seabirds in the Northern Hemisphere and the most abundant seabird on the Faroe Islands. Except from a few sporadic observations up until the 1950´s no study has focused on this species on the Faroe Islands. LÄS MER

  7. 30. Quantification of sources and removal mechanisms of atmospheric aerosol particles

    Författare :Henrik Grythe; Johan Ström; Dominick Spracklen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol; aerosol removal; aerosol emission; aerosol sources; FLEXPART; Arctic aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The focus of this work has been to quantify important processes for climatically relevant aerosols, and to improve our understanding of, and ability to accurately model, aerosols in the atmosphere on a large scale. This thesis contains five papers focused on different parts of the life cycle of atmospheric aerosol particles. LÄS MER
