  1. 1. Genetic structure of natural populations : aspects of the association between genetical and morphological variability patterns

    Författare :Ulf Lagercrantz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; populationsgenetik; Population Genetics;

    Sammanfattning : Most species comprise a number of more or less reproductively isolated subpopulations. These subpopulations may exhibit striking differences in morphology and ecology, and on the basis of those differences they are often given the rank of subspecies, race, stock, variety, etc. LÄS MER

  2. 2. Genetic processes in small populations : conservation and management considerations with particular focus on inbreeding and its effects

    Författare :Linda Laikre; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetik; Inavel; Populationsgenetik;

    Sammanfattning : .... LÄS MER

  3. 3. Hidden biodiversity in an alpine freshwater top predator : Existence, characteristics, and temporal dynamics of cryptic, sympatric brown trout populations

    Författare :Anastasia Andersson; Linda Laikre; Nils Ryman; Paulo Prodöhl; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cryptic sympatry; population genetic structure; sympatric populations; intraspecific biodiversity; genetic monitoring; conservation genetics; trophic polymorphism; genetic connectivity; temporal stability; Salmo trutta; populationsgenetik; Population Genetics;

    Sammanfattning : Intraspecific genetic diversity is imperative to the survival of species in a changing environment, and it plays a vital role in ecosystem function. Since this type of diversity can be difficult to detect it is sometimes referred to as “hidden biodiversity”. LÄS MER

  4. 4. Monitoring gene level biodiversity - aspects and considerations in the context of conservation

    Författare :Johan Charlier; Linda Laikre; Nils Ryman; Kjetil Hindar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brown trout; conservation genetics; genetic drift; genetic monitoring; effective population size; moose; one-sample approach; spatial genetic structure; statistical power; temporal data; populationsgenetik; Population Genetics;

    Sammanfattning : The objectives of this thesis relate to questions needed to be addressed in the context of genetic monitoring for implementing the Convention on Biological Diversity for the gene level. Genetic monitoring is quantifying temporal changes in population genetic metrics. LÄS MER

  5. 5. Exploring the role of gene duplications in plant-insect interactions

    Författare :Hanna Nicole Dort; Christopher Wheat; Noah Whiteman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant-insect interactions; comparative genomics; detoxification; transcriptomics; nitrile-specifier proteins; butterflies; populationsgenetik; Population Genetics;

    Sammanfattning : As evolutionary biologists, we are often curious about the genomic origins of our favorite adaptations. Although some innovations certainly arose de novo, many more originated through the process of whole-gene or within-gene duplication. LÄS MER
