  2. 1. Genetic Variation and Relatedness of Freshwater Pearl Mussel Margaritifera margaritifera L. populations

    Author : Amra Hadzihalilovic-Numanovic; Larry Greenberg; Nils Ryman; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Margaritifera margaritifera; genetic variation; age structure; genetic distance; Biology; Biologi; Biology; Biologi;

    Abstract : The two papers presented in this thesis focus on population genetic study on freshwater pearl mussel populations in Sweden, using RAPD method. In paper I, I examine genetic variation within and between 5 populations in a single drainage area in south western Sweden. READ MORE

  4. 2. Genetic variation in structured populations

    Author : Marina Rafajlovic; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genetic variation; varying population size; effective population size; mutation; recombination; migration; multiple paternity; geographic structure; tests of neutrality; gene tree; species tree;

    Abstract : It is widely acknowledged that the process of speciation in the presence of gene flow between different ecotypes is common in nature. However, the mechanisms underlying speciation are not understood. READ MORE

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

    Author : Kim H. Berndt; Enhet akvatisk ekologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia

    Author : Anna Palmé; Nils Ryman; Linda Laikre; Kerry Naish; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological diversity; conservation genetics; management unit; spatial genetic structure; sympatric populations; genetic monitoring; release of alien populations; northern pike; brown trout; harbour porpoise; Biology; Biologi; populationsgenetik; Population Genetics;

    Abstract : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. READ MORE

  7. 5. Genetics and ecology of natural populations

    Author : Elisabeth Lundqvist; Ulf Lagercrantz; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Angelica archangelica; Bistorta vivipara; Viscaria alpina; Eiseniella tetraedra; ecotypes; hydrochory; genetic differentiation; clone diversity; genetic patterns; riparian;

    Abstract : I have studied the genetic variation of single species using morphological variation and enzyme electrophoresis. I have striven to understand the interaction between the breeding structure and the ecology of the species in relation to the community, in which it lives. The work was done in the county of Västerbotten, northern Sweden. READ MORE
