  1. 1. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective

    Författare :Susanne Gustafsson; Pia Mutikainen; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Genetic engineering; Orchidaceae; Gymnadenia; conservation; microsatellites; genetic structure; mating pattern; Genteknik; Genetic engineering including functional genomics; Genteknik inkl. funktionsgenomik; naturvårdsbiologi; Conservation Biology;

    Sammanfattning : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. LÄS MER

  3. 3. Biodiversity patterns and the processes regulating them along elevation gradients in the Swedish mountains

    Författare :Johannes Måsviken; Love Dalén; Anne Bjorkman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; elevation gradients; spiders; insects; plants; latitude; altitude; alpha diversity; beta diversity; taxonomic diversity; phylogenetic diversity; functional diversity; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Biodiversity describes the total variation of life and includes the taxonomic, genetic, and phenotypic differences among organisms. Variations of biodiversity in space and time may be driven by ecological, evolutionary, or neutral processes. LÄS MER

  4. 4. Advances in studying the role of genetic divergence and recombination in adaptation in non-model species

    Författare :Ramprasad Neethiraj; Christopher Wheat; Sören Nylin; Mathieu Joron; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Recombination; Genetic divergence; Lepidoptera; Genetic variation; Genetic diversity; Holocentric chromosomes; cis-regulatory variation; Allele-specific expression; populationsgenetik; Population Genetics;

    Sammanfattning : Understanding the role of genetic divergence and recombination in adaptation is crucial to understanding the evolutionary potential of species since they can directly affect the levels of genetic variation present within populations or species. Genetic variation in the functional parts of the genome such as exons or regulatory regions is the raw material for evolution, because natural selection can only operate on phenotypic variation already present in the population.

  5. 5. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)

    Författare :Helena Eklöf; Pär K. Ingvarsson; Xiao-Ru Wang; Carolina Bernhardsson; Katri Kärkkäinen; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Picea abies; forestry; genetic diversity; seed orchards; forest management; WGS; GBS; sequencing; PoolSeq; capture probes; genetic differentiation;

    Sammanfattning : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. LÄS MER
