  1. 1. Colonisation and PAH degradation by wood-rotting fungi in contaminated soil

    Författare :Erik Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural hydrology; Soil Science; Bioteknik; Biotechnology; PLFA; PAH metabolites; PAH; degradation; contaminated soil; soil; brown-rot fungi; white-rot fungi; Colonisation; fungal growth; Lantbrukshydrologi; marklära; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Bioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. LÄS MER

    Sammanfattning : Using data from long-term studies of the vegetation in two areas under primary succession, patterns of colonisation and the accumulated seed bank during plant succession were studied.At century-old small islands in Lake Hjälmaren, Sweden, the genetic structure of differently old populations of Moehringia trinervia and Lythrum salicaria was studied, using allozyme variation for M.

  4. 3. Living on Another Shore : Early Scandinavian Settlement on the North-Western Estonian Coast

    Författare :Felicia Markus; Anders Kaliff; Göran Hoppe; Kerstin Cassel; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Estonia; Estonian Swedes; Scandinavian settlement; Iron Age; early Medieval Period; colonisation; ethnic identity; migration; Baltic Sea; contacts; Christianisation; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

    Sammanfattning : Prior to the Second World War, there was a Swedish-speaking population settled on the north-western Estonian coasts. The early history of this group is largely unknown. No colonisation is mentioned in the written sources. The earliest such sources that mention Swedes originate in the late thirteenth century. LÄS MER

  5. 4. The ecological significance of sexual reproduction in peat mosses (Sphagnum)

    Författare :Sebastian Sundberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Bryophyte; colonisation; disturbance; experiment; longevity; mire; safe site; spore; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Peat mosses (Sphagnum) are widely distributed and are a major component of mire vegetation and peat throughout the boreal and temperate regions. Most boreal Sphagnum species regularly produce sporophytes, but the ecological role of the spore has been questioned. LÄS MER

    Sammanfattning : Huvudsyftet med avhandlingen är att förstå hur människor tänker om och hanterar kärlek, sexualitet och hälsa i sina vardagliga liv på landsbygden i nordöstra KwaZulu Natal i Sydafrika. Målet är att förstå vad kärlek innebär för dem, men också hur större samhälleliga processer påverkar erfarenheter av kärlek, hälsa och relationer. LÄS MER
