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

    Author : Susanne Gustafsson; Pia Mutikainen; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Ramprasad Neethiraj; Christopher Wheat; Sören Nylin; Mathieu Joron; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Helena Eklöf; Pär K. Ingvarsson; Xiao-Ru Wang; Carolina Bernhardsson; Katri Kärkkäinen; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria

    Author : Markus Johansson; Anssi Laurila; Juha Merilä; Craig R. Primmer; Michael W. Bruford; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; agriculture; agrochemicals; amphibians; effective population size; genetic diversity; genetic structure; hierarchical sampling; microsatellites; Rana temporaria; Biologi; Biology; Biologi;

    Abstract : The aims of this thesis were to evaluate the effects of agriculture on amphibians in terms of (i) population genetic consequences of agriculture-induced spatial changes of the landscape and (ii) local adaptation and tolerance to frequently used agrochemicals. The study was performed using the common frog Rana temporaria as a model. READ MORE
