  1. 1. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

    Författare :Kim H. Berndt; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

    Sammanfattning : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. LÄS MER

  3. 2. Influence of Admixtures on Crystal Nucleation of Vanillin

    Författare :Osvaldo Pino-García; KTH; []
    Nyckelord :Crystallization; nucleation; vanillin; admixtures; additives; impurities; induction time; interfacial energy; molecular modelling; interaction energy;

    Sammanfattning : Admixtures like reactants and byproducts are solublenon-crystallizing compounds that can be present in industrialsolutions and affect crystallization of the main substance.This thesis provides experimental and molecular modellingresults on the influence of admixtures on crystal nucleation ofvanillin (VAN).

  4. 3. Past demography and local adaptation in forest trees : Insights from natural populations and breeding programs of Norway spruce

    Författare :Lili Li; Martin Lascoux; Brunno Fady; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clines; demographic history; local adaptation; Picea abies; Picea obovata; population genetic structure; Swedish breeding program; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Spatial changes in natural selection patterns can give rise to local adaptation and genetic differentiation between populations. Local adaptation for phenological traits is pronounced in many forest tree species. LÄS MER
