1. 21. Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture

   Författare :Ellika Faust; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conservation; Population structure; Genetics; Aquaculture; Hybridization; Corkwing wrasse; Cleaner fish; Sea lice; Symphodus melops; Escapee; Range expansion;

   Sammanfattning : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. LÄS MER

3. 22. Disentangling small genetic differences in large Atlantic herring populations: comparing genetic markers and statistical power

   Författare :Lena C. Larsson; Linda Laikre; Nils Ryman; Lorenz Hauser; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; marine fish; spatial and temporal genetic variation; molecular marker comparison; allozyme; microsatellite; selection; fisheries management; Biology; Biologi; populationsgenetik; Population Genetics;

   Sammanfattning : Genes are the foundation of evolution and biodiversity. The genetic structure of natural populations needs to be understood to maintain exploited resources rationally. This thesis focuses on genetic variability and methods to determine spatial and temporal genetic heterogeneities. LÄS MER

4. 23. Multiphoton Microscopy Targeting Tissue Development. Towards the real-time imaging of epidermal differentiation

   Författare :Monika Malak; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiphoton microscopy; fluorescence lifetime imaging; epidermal differentiation; reconstructed human epidermis; organ-on-a-chip; intrinsic fluorescence;

   Sammanfattning : The development of novel organ-on-a-chip models calls for methodologies, which will allow the study of tissue development and pharmacological outcome in real-time. Multiphoton microscopy (MPM) has been proposed as a suitable technique for noninvasive imaging of live specimens, utilizing intrinsic tissue fluorescence. LÄS MER

5. 24. Biomarkers aiming at cancer risk estimation of polycyclic aromatic hydrocarbons

   Författare :Hans Helleberg; Kimmo Peltonen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Biology; fysikalisk biologi;

   Sammanfattning : Polycyclic aromatic hydrocarbons (PAH), a family of compounds that are formed in incomplete combustion of organic matter, occur as general pollutants in air and food. Exposure to PAH is, according to preliminary estimates, associated with non-acceptable cancer risks showing the need for improved data to be used in risk estimation. LÄS MER

7. 25. The use of molecular markers for identifying species diversity and functional variation of ectomycorrhizal fungi

   Författare :Jenny Hedh; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ectomycorrhiza; molecular markers; Paxillus involutus; ITS region; phylogenetic species; host compatibility; gene expression; CGH;

   Sammanfattning : Ectomycorrhiza (EM) is a symbiosis between soil living fungi and the roots of woody plants. EM fungal communities are important in forest nutrient cycling, they are species rich and their structures vary between habitats and over time. LÄS MER
