  1. 11. Single-cell population genetics and dispersal limitation of a bloom-forming microalga

    Författare :Raphael Gollnisch; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gonyostomum semen; algal blooms; invasive species; population structure; RADseq; single-cell whole genome amplification; multiple displacement amplification; calcium; pH; iron;

    Sammanfattning : Microalgal range expansions are increasing in frequency and magnitude worldwide mostly due to anthropogenic factors. However, they often remain unnoticed until mass development (algal blooms) occurs due to difficulties in detection when population densities are low. LÄS MER

  3. 12. From data to decision - learning by probabilistic risk analysis of biological invasions

    Författare :Ullrika Sahlin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probabilistic models; establishment success; prediction; forecasting; uncertainty; risk; invasive species; Bayesian methods;

    Sammanfattning : Predicting an uncertain future with uncertain knowledge is a challenge. The success of efforts to preserve biodiversity, to maintain biosecurity and to reduce a negative impact from climate change, depend on scientifically based predictions of future events. LÄS MER

    Sammanfattning : This thesis takes the conservator as a starting point to explore more-than-human aspects of the museum of modernity. Assuming that built-in obstacles impinge when museums today deal with environmental issues‚ it investigates new and alternative perspectives on the engagement with our immediate surroundings, in this case the museum objects.

  5. 14. Non-invasive monitoring of low molecular weight biomarkers relevant to skin inflammation and cancer

    Författare :Skaidre Jankovskaja; Tautgirdas Ruzgas; Johan Engblom; György Marko-Varga; Melinda Rezeli; Pawel Lukasz Urban; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tryptophan; Kynurenine; Phenylalanine; Tyrosine; Low molecular Weight Biomarkers; Non-Invasive; Skin Surface Sampling; Skin Permeability; Hydrogels; Prussian White; Health and society; Hälsa och samhälle;

    Sammanfattning : Development of skin inflammation and cancer in viable epidermis and dermis involve slow molecular weight (LMW) metabolites. We hypothesize that these LMW compounds can be collected on the surface of the skin and used for non-invasive diagnostics of skin disorders. LÄS MER

  7. 15. Large-scale releases of native species : the mallard as a predictive model system

    Författare :Pär Söderquist; Högskolan Kristianstad; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Anas platyrhynchos; Farmed; Hunting; Introgression; Longevity; Mallard; Migration; Morphology; Population genetic; Restocking; SNPs; Sweden;

    Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.
