  1. 11. Tillhör vi Sveriges framtid? : En etnologisk studie av vardag och hållbarhet i norrländsk glesbygd

    Författare :Elisabeth Wollin Elhouar; Kjell Hansen; Barbro Blehr; Håkan Berglund-Lake; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Phenomenology; policy; social sustainability; sparsely populated areas; community; place; infrastructure; everyday life; center and periphery; Ethnology; etnologi;

    Sammanfattning : This dissertation concerns everyday life and sustainability in sparsely populated parts of Northern Sweden. The aim is to study how sustainability is constructed, experienced, practised and perceived in a field of tension between local everyday life and political discourses. LÄS MER

  3. 12. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies

    Författare :Carsten Meyer-Jacob; Richard Bindler; Hendrik Vogel; Jan Karlsson; John F. Boyle; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fourier transform infrared spectroscopy; visible-near infrared spectroscopy; PLS regression; biogenic silica; climate change; carbon cycling; lake-water quality; geochemistry; paleolimnology; Holocene; Lake El’gygytgyn; Torneträsk;

    Sammanfattning : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. LÄS MER

  4. 13. Significance and Diversity of Lake Bacteriophages

    Författare :David Lymer; Eva Lindström; Lars Tranvik; Ruth-Anne Sandaa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; viral ecology; lake; bacteriophage; diversity; phosphorus; Freshwater ecology; Limnisk ekologi;

    Sammanfattning : Viruses has a relatively recently been discovered in high abundances in aquatic systems. Their possible importance has therefore been largely overlooked. LÄS MER

  5. 14. Diatoms in Lake Duluti : Tracking Environmental Variability in Northern Tanzania during the Past 1000 Years

    Författare :Helena Öberg; Lars-Ove Westerberg; Karin Holmgren; Jan Risberg; Robert Marchant; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleolimnology; Tanzania; Diatoms; Climate change; Crater lake; Physical Geography; naturgeografi;

    Sammanfattning : The tropics are the regions which are least understood climatically and new data on past climate variability is necessary for reliable future modeling of climate change. This thesis contributes with new paleoenvironmental information from a small crater lake in northern Tanzania and provides an additional link between the integrated history of climate, environment and socioeconomic variability in tropical Africa.
