  1. 1. Substructure dynamics : In-situ annealing coupled with numerical modelling

    Författare :Verity Borthwick; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : The understanding of substructural behaviour during post-deformational annealing is key to interpreting rheological adjustments during tectonic change, and the processes which cause them. The focus of this study is to use coupled in-situ experimental techniques with numerical simulation to increase understanding of substructure dynamics in geological materials. LÄS MER

  3. 2. Fundamentals of substructure dynamics : In-situ experiments and numerical simulation

    Författare :Verity Borthwick; Sandra Piazolo; Dorte Juul Jensen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; halite; in-situ; X-ray diffraction; EBSD; annealing; substructure; modelling; Earth sciences; Geovetenskap; Geology; geologi;

    Sammanfattning : Substructure dynamics incorporate all features occurring on a subgrain-scale. The substructure governs the rheology of a rock, which in turn determines how it will respond to different processes during tectonic changes. LÄS MER

  5. 4. 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

  7. 5. Population Genetic Analyses of Natal Dispersal and Substructure in Three Bird Species

    Författare :Tobias Sahlman; Jan Ekman; Jacob Höglund; Ben J. Hatchwell; Uppsala universitet; []
    Nyckelord :Ecology; Perisoreus infaustus; Gallinago media; Lagopus muta; relatedness; philopatry; biased dispersal; phylogeography; microsatellite; mitochondrial DNA; Ekologi;

    Sammanfattning : Genetic variation within and among populations is a result of past and ongoing processes. Among the most important of such processes are dispersal, habitat fragmentation and selection. This thesis use neutral genetic variation as a tool to investigate these processes in three bird species. LÄS MER
