  2. 1. Multiplex markers in a plant breeding perspective

    Author : Mats Hansen; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; plant breeding; SNP; RAPD; molecular markers; AFLP; Växtbiokemi;

    Abstract : Plant breeding is largely depending on the repeated selection for desirable traits. This process is both time and labour consuming, making the development of commercial plant varieties a slow and costly activity. READ MORE

  4. 2. Evolutionary Processes and Spatial Genetic Variation in Euphrasia stricta on the Baltic Island of Gotland

    Author : Anna-Karin Kolseth; Brita Svensson; Mikael Lönn; Joop Ouborg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; genetic differentiation; regional processes; conservation genetics; AFLP; microsatellites; gene flow; local adaptation; shape analysis; Ekologi;

    Abstract : The identification of processes governing genetic structure at different spatial scales remains a major challenge in evolutionary biology and is of considerable applied interest in conservation biology. In Euphrasia stricta five varieties have been identified (brevipila, gotlandica, stricta, suecica and tenuis) based on differences in habitat, phenology and morphology. READ MORE

  5. 3. Investigating genetic factors behind the decline of a threatened plant species – Tephroseris integrifolia (Asteraceae)

    Author : Kerstin Isaksson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantitative genetics.; AFLP; local genetic variation; relict populations; fragmentation; small populations; sporophytic self-incompatibility; extinction; threatened species; Inbreeding depression; population structure;

    Abstract : Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. READ MORE

  6. 4. Quantitative Genetics and Genome Structure in a Wild Population: the Use of a Great Reed Warbler Pedigree

    Author : Mikael Åkesson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; genome mapping ; AFLP; microsatellite; synteny; heterochiasmy; recombination; chicken; great reed warbler ; bird; Genetics; cytogenetics; Genetik; cytogenetik; Animal ecology; trait correlation ; Djurekologi; animal model ; selection; Djurs anatomi och morfologi; animal morphology; Animal anatomy; heritability;

    Abstract : Long-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population.

  7. 5. Ecology of red admiral migration

    Author : Oskar Brattström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nymphalidae; Lepidoptera; migration patterns; migration; genetic structure; AFLP; lipid content; Inachis io; stable isotopes; orientation; navigation; weather; Animal ecology; red admiral; Vanessa atalanta; Djurekologi;

    Abstract : The red admiral (Vanessa atalanta) is a migratory butterfly that can be found in North America, North Africa, Europe and some parts of Asia. In Europe the main part of the population spend winter in the Mediterranean region and the following spring leave this area to breed further to the north. READ MORE
