    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis deals with variation in mortality of roe deer fawns, over time and in space, caused by red fox and Eurasian lynx predation in a boreal landscape. The thesis considers historic and recent effects of vole population dynamics on red fox predation on roe deer fawns, using long term time series from Grimsö Wildlife Research Area. LÄS MER

  3. 7. Wide-scope screening for contaminants of emerging concern in archived biota: Method development, suspect prioritisation, and non-target screening in a novel identification tool

    Författare :Wiebke Dürig; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Environmental monitoring of hazardous chemicals in wildlife conventionally uses target screening for selected contaminants, but relatively few contaminants are moni-tored and knowledge of potentially hazardous contaminants of emerging concern (CECs) in wildlife is lacking. In this thesis, a non-target screening (NTS) method com-bined with temporal trend analysis was developed and applied as a prioritisation tool for identification of CECs in top predators, using high-resolution mass spectrometry (HRMS).

  4. 8. The return of the wolf : effects on prey, competitors and scavengers

    Författare :Camilla Wikenros; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Apex predators may have both direct and indirect effects on other species through predation and competition. I investigated the effects of wolves (Canis lupus) on prey species, competitors (including humans) and the scavenging guild after the re-colonization by wolves of the Scandinavian Peninsula. LÄS MER
