    Nyckelord :tropical humid forest; deforestation; land-use change; slash-and-burn agriculture; spatial variation; vertical distribution; multielement analysis; sustainable development; rural livelihoods; bosque húmedo tropical; deforestación; cambios de uso de la tierra; agricultura de tala y quema; variabilidad espacial; distribución vertical; análisis multielemental; desarrollo sostenible; cambio climático; sustentos rurales; Miljövetenskap; Environmental Science;

    Sammanfattning : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.

  7. 5. Distribution and activity of pelagic fish - acoustic studies in the Baltic Sea

    Författare :Tomas Didrikas; Sture Hansson; Thomas Mehner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pelagic; fish; hydroacoustic; distribution; activity; Baltic; Biology; Biologi;

    Sammanfattning : Fisheries agencies around the Baltic Sea use hydroacoustics to assess stock sizes of herring and sprat. These assessments rely on the assumption that the acoustic properties of Baltic clupeids are the same as North Sea herring. LÄS MER
