  1. 16. Endocrine disruption in fish : Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome

    Författare :Tove Porseryd; Inger Porsch Hällström; Ioanna Katsiadaki; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 17α-ethinylestradiol; endocrine disrupting chemical; fish; behavior; fertility; transcriptome; RNA sequencing; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. LÄS MER

  3. 17. Processes and factors governing benthic community dynamics—environmental change in the Baltic Sea

    Författare :Christian Sommer; Sara Sjöling; Patrik Dinnétz; Inger Porsch Hällström; Alexander Eiler; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Benthic communities; Baltic Sea; biodiversity; community composition; environmental change; environmental genomics; microbial ecology; Major Baltic Inflow; meta-population; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : As drivers of biogeochemical cycles and nutrient recycling, such as carbon turnover, the microbial community is essential in sustaining functioning ecosystems. Together with the metazoan community, the microbial community constitute the majority of all life in the benthos. LÄS MER

  4. 18. New Tides in Shipping : Studying incumbent firms in maritime energy transitions

    Författare :Ignė Stalmokaitė; Björn Hassler; Johanna Yliskylä-Peuralahti; Tommy Larsson Segerlind; René Taudal Poulsen; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; shipping; incumbent firms; maritime energy transitions; multi-level perspective; dynamic capabilities; regime-niche interactions; decarbonisation; air-borne emissions; sustainability transitions; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Shipping is a cornerstone of global transportation responsible for moving large volumes of traded goods. At the same time, negative environmental impacts of shipping operations have attracted growing concerns. LÄS MER

  5. 19. The “Dark Side” of Marine Spatial Planning : A study of domination, empowerment and freedom through theories of discourse and power

    Författare :Ralph Voma Tafon; Michael Gilek; Fred P. Saunders; Wesley Flannery; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine spatial planning; discourse; power; domination; empowerment; freedom; conflict; resistance; small-scale fisheries; offshore wind energy; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : This thesis aims to contribute to the marine spatial planning (MSP) literature by elaborating a robust theoretical account of power for a more rigorous and balanced critical analysis of MSP. Conceived as a problem-solving regime, MSP has emerged as a radical approach to govern the use and protection of marine resources. LÄS MER

  7. 20. Microbial Ecosystem Functions Along the Steep Oxygen Gradient of the Landsort Deep, Baltic Sea

    Författare :Petter Thureborn; Sara Sjöling; Mats Grahn; Matthias Labrenz; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbial ecology; ecosystem functions; microbial community; bacteria; archaea; metagenomics; metatranscriptomics; oxygen gradient; hypoxia; sediment; Baltic Sea; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Through complex metabolic interactions aquatic microbial life is essential as a driver of ecosystem functions and hence a prerequisite for sustaining plant and animal life in the sea and on Earth. Despite its ecological importance, infor­mation on the complexity of microbial functions and how these are related to environmental conditions is limited. LÄS MER
